Associations Between Inflammation And Fatigue
IL-6 was marginally correlated with fatigue . Women with higher IL-6 values reported marginally greater average levels of fatigue and fatigue severity. The associations between IL-6 and fatigue indices remained marginally significant when physical activity was added to the model . After controlling for age and BMI, the associations between IL-6 and fatigue were not significant . CRP was not associated with any indices of fatigue.
How Heart Rate Can Tell You When To Rest
If you are experiencing a high level of perceived exertion and a hard time elevating your heart rate following a period of rest, that is a sign that additional rest is needed before taking on more training volume and intensity. At this point, making a change to the plan and backing off for a few additional days would be wise. Complete rest or a few days of easier spins may be all it takes to see heart rates respond more easily and while experiencing lower perceived exertions.
Sometimes it takes much longer than anticipated to gain good rest, so if youre recovering from a hard race or experiencing overtraining symptoms, listen to feedback from your heart, as well as overall feel and mindset to determine when it is best to start back into more intense training.
If you’re in the midst of a training block, know that you are beginning to push the limits when you can elevate your heart rate into the prescribed ranges for the prescribed durations, but experience a higher than normal perceived exertion. For example, if you are able to work into the upper zones with a responding heart rate, but you experience a higher than normal perceived exertion or experience more leg fatigue than usual, then you are beginning to push the limits.
Heart Rate Trends Over A Training Block
When starting into the first week of a new training period after a week of reduced hours or a longer period of rest, it is a common trend to see heart rates elevate quickly, accompanied by a low to moderate perceived exertion. This is a sign of being well-rested and gives the green light to press on through the week and training period. While the study cited above supports that absent of factors such as fatigue, it common to see heart rates respond with little variation through the first week and most of the second week of training.
As you work through your second week and into your third, you may experience slightly more variation in heart rate and an increase in perceived exertion in all heart rate ranges. It will most likely become harder for you to elevate your heart rate as you build training fatigue, but that is of course part of the goal. You want to experience greater amounts of fatigue towards the end of a training block, but you also want to recognize when you are pushing your limits too far to prevent working into an over-trained state.

What Are The Symptoms Of Arrhythmia
Some patients have no associated symptoms with arrhythmia, while others may notice symptoms but not have a life-threatening arrhythmia. It is important to have regular check-ups with your GP, especially if you are concerned.
Common symptoms of a heart arrhythmia include:
- Fluttering feeling in the chest
- Racing heartbeat

Does Heart Rate Affect Blood Pressure
Heart rate and blood pressure are controlled separately. However, they can impact each other. This is especially true at extremes, such as when heart rate is very high or blood pressure is very low.
In some cases, heart rate has a direct effect on blood pressure. For example, if the heart rate becomes dangerously high, such as during an arrhythmia, blood pressure often drops. This happens because the heart rate is too high for the heart to pump blood effectively.
On the other hand, blood pressure can also have an effect on heart rate. If you experience a condition called shock, in which the blood pressure is dangerously low, the heart rate typically rises. It does so to try to compensate and provide blood flow to the body. For example, this is seen in hypovolemic shock caused by low blood volume.

Follow Your Heart: Using Hr To Gauge Fatigue
When it comes to training, heart rate is most often used to help measure intensity and maintain a consistent pace. However, heart rate can also provide key information about your current training status and level of fatigue.
Heart rate is one of the most widely used tools to help measure training intensity. The heart rate monitors of today are more accurate than ever, come with many functions, and provide a reliable source of feedback. Understanding how to use the feedback from your heart is the key. When it comes to training, heart rate is most often used to help measure intensity and maintain a consistent pace. However, heart rate can also provide key information about your current training status and level of fatigue.
Understanding Your Heart Rate By The Numbers
If youre curious about your heart rate, you can measure it yourself. First, find your pulse by holding a finger to the radial artery on the inside of your wrist. Then, count the number of beats per minute while youre resting.
Other places your heart rate can be measured include:
- on your neck, alongside your windpipe
- inside your elbow
- on the inside of your groin/upper thigh
- on the top of your foot
When youre determining your heart rate, here are some numbers to keep in mind:
- A resting adult heart rate is normally between

Stress Burnout And Heart Health
Vital exhaustion is more than just depression.
The World Health Organization ties burnout to chronic workplace stress that has not been successfully managed. It may show up as exhaustion, being cynical about work, or feeling less effective at your job.
A recent Gallup poll found that about two-thirds of full-time workers experienced burnout on the job, with almost one-quarter feeling burned out very often or always.
Among physicians, burnout is just as high around 67 percent .
However, study author Dr. Parveen Garg, an associate professor of clinical medicine at the University of Southern Californias Keck School of Medicine, told CNN that burnout can be caused by any stressor, including personal stress or tension at home or in your family.
Dr. J Shah, a cardiologist in Boulder, Colorado, and author of Heart Health: A Guide to the Tests and Treatments You Really Need, said anger, anxiety, and depression have all been linked to the development of coronary artery disease and congestive heart failure.
But the impact on AF has not been established, said Shah, who wasnt involved in the study.
Previous research on the link between AFib and mental health has been mixed.
In one , young and middle-age veterans with post-traumatic stress disorder had a higher risk of developing AFib.
Shortness Of Breath Or Chest Pain After Covid
Shortness of Breath
You want to consult a doctor if any of your symptoms are severe, especially shortness of breath, Post says. She recommends using a commercially available O2 saturation monitor.
Shortness of breath by itself is not always a sign of a serious problem, but if you have that symptom along with low O2 , that is a reason to be concerned. Sometimes people are short of breath with exertion after COVID-19 because they have been less active for a long time and need to gradually build their fitness level back up.
COVID-19 Chest Pain
What about lingering chest pain, another common post-COVID complaint? Chest pain may be nothing serious, but if you are having severe chest pain, get help, especially if it is persistent or if you are also having nausea, shortness of breath or lightheadedness: These could be symptoms of a heart attack.
If you have chest pain when you inhale, you might have lung inflammation. Sudden, severe chest pain could be a blood clot in the lung , Post says.
Family doctor or cardiologist?
If your symptoms are not severe but you want to be checked out, Post says a cardiologist doesnt need to be your first stop if youve never had heart problems before and are not at risk. For nonemergency post-COVID-19 symptoms, your primary care practitioner can advise you, she says.

Other Heart Electrical Issues
If the heart is unable to send electrical signals due to a blockage or heart disease, this can lead to bradycardia.
Complete heart block is when there is a total loss of communication between a persons atria and the ventricles. This occurs when the SA node is unable to pass a signal to the AV node.
Complete heart block results in a persons atria and ventricles activating independently of each other. It can be fatal if a person does not receive treatment for complete heart block quickly.
How Your Heart Works
Your heart has a right side and a left side, separated by a wall. Each side has a small collecting chamber , which leads into a large pumping chamber . There are four chambers the left atrium and right atrium , and the left ventricle and right ventricle .
Normally, the upper chambers of your heart contract first and push blood into the lower chambers . The ventricles then contract the right ventricle pumping blood to your lungs and the left ventricle pumping blood to the rest of your body.
In a healthy heart, heartbeats are set off by tiny electrical signals that come from your hearts natural pacemaker a small area of your heart called the sinus node, located in the top of the right atrium. These signals travel rapidly throughout the atria to make sure that all the hearts muscle fibres contract at the same time, pushing blood into the ventricles.
These same electrical signals are passed on to the ventricles via the atrioventricular node and cause the ventricles to contract a short time later, after they have been filled with blood from the atria. This normal heart rhythm is called the sinus rhythm, because it is controlled by the sinus node.

Treatment Of Cardiac Arrhythmia
Treatment is often required if the arrhythmia causes significant symptoms putting the patients at risk of a more serious arrhythmia or arrhythmia complications. However, treatment of cardiac arrhythmia may vary among individuals, depending on type of arrhythmia and its severity as well as each patients condition.
Heart Rate Variability Analysis
Heart rate variability was assessed between 3:00 pm and 6:00 pm in a semi-dark room maintained at a temperature between 20 and 24 °C during weekdays. At the start of each test session, all subjects were asked to abstain from alcoholic and caffeinated beverages, cigarette smoking, cardioactive medications and heavy exercise for at least 48 h prior to testing, as their actions might alter their autonomic function. After 5 min of rest lying down, participants were asked to remain in supine position and still without speaking or making any movements, and HRV data were recorded continuously for 5 min of natural breathing. Participants session ratings of continuous heart rate were collected and analysed with the FitLab® system an application that runs on a mobile device connected via Bluetooth with a cardiac chest band and connected via wireless to a remote server. The system allows performance of individual HRV recordings in each session and checks data quality in real time. All participants performed the three 5-min HRV tests at rest in the supine position. The intervals between consecutive heartbeats were continuously monitored over three 5-min periods on different days.
Heart rate variability analysis was performed for RR intervals in 5 min periods using the FitLab® software, following the recommendations of the Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology .

How Are Arrhythmias Treated
Many arrhythmias dont need treatment. For those that do, these options might be used:
- Medicines. Many types of prescription anti-arrhythmic medicines are available to treat arrhythmia. Sometimes, these can increase symptoms and cause side effects, so the patient will be closely watched by the doctor.
- Pacemakers. A pacemaker is a small battery-operated device implanted into the body through a surgical procedure. Connected to the heart by a wire, a pacemaker can detect if the heart rate is too slow and send electrical signals to speed up the heartbeat.
- Defibrillators. A small battery-operated implantable cardioverter defibrillator is surgically placed near the left collarbone. Wires run from the defibrillator to the heart. The ICD senses if the heart has a dangerously fast or irregular rhythm and sends an electrical signal to restore a normal heartbeat.
- Catheter ablation. A catheter is guided through a vein in the leg to the heart. Arrhythmias often are caused by microscopic defects in the heart muscle. Once the problem area of the heart is pinpointed, the catheter heats or freezes the defective muscle cells and destroys them.
- Surgery. Surgery is usually the treatment recommended only if all other options have failed. In this case, a person is put under anesthesia and a surgeon removes the tissue causing the arrhythmia.
What Is Kidney Failure
Kidney failure, also known as end-stage kidney disease, occurs when the kidneys are no longer able to adequately remove waste from your blood and control the level of fluid in your body. Kidney failure can happen suddenly or gradually. People with kidney failure need dialysis or a kidney transplant to stay alive.
If you have kidney disease, it does not mean that you will develop kidney failure. One in ten Australians aged 18 and over has at least one sign of chronic kidney disease, and over 23,000 Australians receive dialysis or a kidney transplant for kidney failure.
You can lose up to 90 per cent of your kidney function before experiencing symptoms. In many cases, the signs of disease arent noticed until the kidneys are close to failure.

What Are The Symptoms Of Chronic Fatigue Syndrome
This serious, long-term condition involves a lot more than just tiredness. People with CFS can also experience loss of memory/concentration, enlarged lymph nodes in the neck or armpits, headaches, and more. Some heart-related abnormalities can indicate that you have CFS in fact, many with CFS have an unusually high heart rate and low blood pressure after standing for a while, but this may be more due to altered automatic nerve reflexes.
To be clear, CFS does not cause a heart attack. The symptom of fatigue may indicate heart artery disease, but it can also be a factor in other conditions, such as sleep disorders or thyroid problems. Thats why its best to see your provider before you panic and assume the worst.
Path Analyses Testing Inflammation As A Mediator Of Hrv And Fatigue
Next, we conducted path analyses to test whether the association between HRV and fatigue was mediated by IL-6 or CRP. The models are illustrated in Figure 1. We selected RMSSD as the predictor variable and FSI average as the dependent variable for these analyses based on results from the correlation and regression analyses. Note that mediational effects may still be present when the relationship between the independent and dependent variable is weak . Age and BMI were included as covariates in all models. Results showed that neither IL-6 nor CRP were significant mediators of the association between RMSSD and average fatigue.

Slow Heartbeat And Anxiety
If you suffer from anxiety symptoms generally and you also have what appears to be a slow heart rate, it is entirely possible that the two are related.
The causes of slow heart rate in the case of anxiety are not entirely clear. However, here are some possible causes:
Stop Checking Your Pulse
You should see a doctor if you’re concerned about a low heart rate. But once the doctor rules out medical symptoms, you need to stop checking your pulse unless instructed to do so by a doctor. Persistent pulse checking is a symptom of anxiety, and it’s a symptom that serves to fuel and reinforce your existing anxiety problem.
This behavior is self-sustaining. For example, when you check your pulse multiple times a day, you’ll never be satisfied with a normal result. You’ll instead keep checking until you finally have the anomaly you’ve been waiting for, which will then reinforce the idea that you need to keep checking your pulse constantly.
On the other hand, every time you check your pulse and you see that its normal, this gives you a bit of a buzz, temporarily alleviating your anxiety and giving you a sense that everything is ok. That positive feeling reinforces not just the pulse taking, but also the anxiety that precedes the pulse-taking. Youll soon find yourself becoming anxious and taking your pulse again, allowing the cycle to repeat.
In either case, the take-home message is that repeatedly checking your pulse is not a helpful behaviour.
