Heart or Pulse is the number of times the heart beats per minute. This happens due to the contractions of the heart per minute. A normal resting heartbeat varies between 60-100 beats per minute. Abnormal Heart Rates or Heart Beats reflect the cardiac conditions of the body. If unnoticed and untreated, this can sometimes be fatal. Conditions when the heartbeat goes beyond 120-140 beats per minute or falls below 60 beats per minute, can be considered dangerous, and immediate doctor’s intervention is a must.
