Is the difference in heart rate between night and day a sign of arrhythmia?

When I have indigestion from eating bread, my heart rate gradually increases from 80 to 120 and my systolic blood pressure increases to 178. Doctor, do I have an arrhythmia? My average heart rate during the day fluctuates between 66-80 beats/minute and at night between 63-70 beats/minute.

Hello!

The normal resting heart rate of an adult ranges from 60 to 100 beats per minute. When the body is under stress or is under stress, or when there are abnormalities in other organs, the heart rate can also increase or decrease.

If the rhythm is still sinus rhythm (through electrocardiogram) and in the situation of gastrointestinal symptoms, it could be a natural reaction of the body. Based on the information you provided, the average heart rate during the day is 66-80 beats/minute, at night from 63-70 beats/minute is within normal limits.

However, you also need to pay attention to the problem of blood pressure increasing to 178mmHg. You need to go to the doctor to determine if you have high blood pressure or not, from which you can have timely treatment measures.

Hello and good health!
