Why do I have a high heart rate despite normal ECG reports?

Question

Hi doctor,

I recently observed that my heart rate, including my resting rate, is high. My resting heart rate is between 75 and 85 beats per minute, while my average brisk walking rate is around 115 to 120 beats per minute. Until recently, I lived a perfectly normal life with 15 to 16 active hours each day. However, during a recent ECG, my doctor informed me that my heart rate was elevated, measuring about 110 beats per minute. My blood pressure was 110/80 mm Hg, and the ECG results were normal. My cholesterol levels are good, and I am currently taking Metformin and Aspirin. My HbA1c is 6.1%.

Please advise.

Hello,

Welcome to icliniq.com.

Regarding your heart rate, a resting heart rate of 75 to 84 beats per minute is generally considered acceptable and does not indicate any major abnormalities. Factors such as exercise, stress, anxiety, smoking, and caffeine can certainly lead to an elevated pulse rate. As you mentioned, your ECG (electrocardiogram) was normal except for the heart rate, which suggests sinus tachycardia. This can occur due to anxiety, especially if you had been brisk walking prior to the test.

Furthermore, your home readings are fine, so there is nothing to worry about. I recommend getting your thyroid and hemoglobin levels tested. An increase in pulse rate during exercise is completely normal. Based on your age, your maximum heart rate is approximately 160 beats per minute. Additionally, try to monitor your pulse rate while sleeping.

Overall, I believe there is no need for concern. However, your HDL (high-density lipoprotein) is lower than expected (the ideal level is above 40). The best way to raise it is through a healthy lifestyle, including a balanced diet low in calories and fats, weight loss, and avoiding smoking and alcohol consumption. Your HbA1c (glycated hemoglobin test) results are also good.

I hope this helps you.

Thank you.
