The normal range of heart rate in hypertrophic cardiomyopathy is 60 to 100 beats/minute, as in normal adults. The normal range of heart rate in hypertrophic cardiomyopathy is the same as that of normal adults, which is 60~100 beats/min, less than 60 beats/min is bradycardia, and more than 100 beats/min is tachycardia. Hypertrophic cardiomyopathy due to the left ventricular outflow tract narrowing obstruction, caused by peripheral vascular blood volume reduction, heart rate accelerated, generally greater than 100 times / min, so the clinic generally need to apply β blocker, slow down the heart rate, reduce myocardial contraction force, so as to reduce the pressure of the outflow tract, the general will be the resting heart rate control in 60 ~ 80 times / about. If you suffer from hypertrophic cardiomyopathy, you should go to the hospital as soon as possible, and take medication or surgical treatment to reduce the obstruction of the left ventricular outflow tract and prevent structural lesions of the heart.
