Hi doctor! I am 20 years old this year, recently I have seen a sudden high heart rate, often up to 100-110, because I wear an Apple watch, so I know. I often have hand tremors, heart rhythm errors and acid reflux.

I have a daughter born in 2000, the history of asthma from 6 years old to 12 years old is gone (hospital treatment). Now that the Covid-19 vaccine has been administered twice, the heart rate is above 120 beats / min, the blood pressure is normal. So the doctor asked me why the high heart rate when I was vaccinated against Covid

During exercise, your heart rate increases and increases with your activity level. Blood flows to your muscles so they can get the oxygen and nutrients they need to function. When running, you should exercise at 50 to 85 percent of your maximum heart rate.
