Why does the heart rate vary between rest and exertion?

Question

Hello doctor,

I have no previous history of heart issues. I am 28 years old, and for the last seven days, my heart rate has been sporadically up and down within seconds. When I am resting, it is in the low 80's or even 70 beats per minute. The minute I move, it can jump to 90 or 100 beats per minute. Anytime I get up and do anything, it goes to a high 100 to 120 beats per minute. It is hard to take a deep breath. My oxygen level is low when monitored during sleep, and it has become difficult to get sleep.

At times, I spit up white sputum, and my urine has turned yellow despite drinking water and not taking any medication. I have been fasting for two days and have not been hungry whatsoever. I tested negative for COVID-19 and influenza, and my EKG (electrocardiogram) seemed fine. My chest feels hit every time I cough. I have been burping a little lately and have had two headaches in seven days. My blood pressure is the same as it has been for a while. I figured it would improve within seven days, but it has worsened in the last three days. I know my body well and have never had these issues.

It is similar to altitude sickness, but it has not gone away. My main concern is when I breathe, it hurts my throat or chest. Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query, and I can understand your concern.

A regular heart rate at rest typically ranges between 60 and 100 beats per minute and increases during physical exertion, which is a normal physiological response. If chest pain occurs, it could be due to muscular causes, such as muscle strain or possibly a chest infection. To properly diagnose the cause, a detailed history and physical examination are necessary. Regarding the shortness of breath and yellow urine, I recommend conducting a few tests to assess the situation more accurately. From a cardiac perspective, your current weight may pose some concern. Maintaining a healthy weight is important for reducing the strain on your heart and overall well-being.

I advise incorporating regular exercise into your routine, as physical activity helps improve heart health lung function, and reduces symptoms of shortness of breath. Additionally, adopting a Mediterranean diet, rich in fruits, vegetables, whole grains, and healthy fats, can provide numerous benefits, including heart disease prevention. Avoiding junk foods that are high in unhealthy fats, sugar, and salt will also support your heart health. Over time, with consistent exercise and dietary changes, your symptoms should ease, and you will experience improved overall health and wellness.

I hope this will help you.

Thank you.

Hello,

Welcome back to icliniq.com.

I have read your query, and I can understand your concern.

Wearable devices are not always accurate. Moreover, machine reading is not always correct. Please share your ECG (electrocardiogram) or wearable device rhythm strip. I may guide you accordingly. Even the best medical-grade devices like ECG machines, cardiac monitors, and pulse oximeters will show variable readings if the patient is not relaxed or moving or if some other electrical appliance is nearby. So, a doctor should interpret these readings.

I hope this will help you.

Thank you.
