Normal range for heart rate
A
60-100 bpm
B
40-60 bpm
C
50-100 bpm
D
6-10 bpm
Explanation: 

Detailed explanation-1: -A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

Detailed explanation-2: -Heart rates that are consistently above 100, even when the person is sitting quietly, can sometimes be caused by an abnormal heart rhythm. A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body.

Detailed explanation-3: -Causes of supraventricular tachycardia (SVT) SVT happens when the electrical system that controls your heart rhythm is not working properly. This causes your heart to suddenly beat much faster. It can then slow down abruptly. A normal resting heart rate is 60 to 100 beats per minute (bpm).
