Heart rate recovery (HRR) is the reduction in heart rate at peak exercise and the rate as measured after a cool-down period of fixed duration. [56] A greater reduction in heart rate after exercise during the reference period is associated with a higher level of cardiac fitness.
Ventricular tachycardia (V-tach or VT) is a fast heart rate arising from the lower chambers of the heart. [6] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
“So you can do things that will briefly lower your heart rate—like deep breathing and meditation—but if you are trying to lower your overall heart rate over a longer period of time, the ...
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [1] Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart).
A faster-than-normal heart rate. Bradycardia. A slower-than-normal heartbeat. Atrial fibrillation (A-fib). An irregular and often very fast heart rate. ... Infections during pregnancy, such as ...
The most efficient way to lower your heart rate is through breathing, says Dr. Wang. “Deep exhalations can decrease your heart rate. Breathing in through the nose for the count of 4, holding it ...
The resting heart rate in children is much faster. In athletes, however, the resting heart rate can be as slow as 40 beats per minute, and be considered normal. [citation needed] The term sinus arrhythmia [26] refers to a normal phenomenon of alternating mild acceleration and slowing of the heart rate that occurs with breathing in and out ...
Cardioversion is a medical procedure by which an abnormally fast heart rate (tachycardia) or other cardiac arrhythmia is converted to a normal rhythm using electricity or drugs. Synchronized electrical cardioversion uses a therapeutic dose of electric current to the heart at a specific moment in the cardiac cycle , restoring the activity of the ...
