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: -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).

Detailed explanation-3: -Why is my heart rate jumping up and down? In adults, a typical resting heart rate is 60–100 beats per minute, but structural or electrical disorders of the heart can cause it to rise or fall. Medications, a lack of sleep, and stress may also be factors.

Detailed explanation-4: -For adults, a normal resting heart rate is between 60 and 100 beats per minute (bpm). The normal resting heart rate for children can be higher than that of adults, depending on their age.

Detailed explanation-5: -Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
