I went for an echocardiogram and an electrocardiogram, and the results showed that when lying down, my heart rate is normal, when standing, my heart rate is about 120 to 130, when exercising up to 171. I went to the doctor and was diagnosed with acid reflux. thick. Doctor let me ask my heart rate when standing 130, when I exercise 171, will I get sick? I would like to thank the doctor.
