The normal heart rhythm (normal sinus rhythm) shows the electrical activity in the heart is following the normal pathway. The rhythm is regular and the node is normal (about 50 to 100 beats per minute).Tachycardia: fast heart rhythm (greater than 100 beats per minute).he normal heart rhythm (normal sinus rhythm) shows the electrical activity in the heart is following the normal pathway. The rhythm is regular and the node is normal (about 50 to 100 beats per minute).
For example, a young, strong, healthy athlete may have a resting heart rate of 30-40 beats per minute, but may easily increase his heart rate to 180 beats per minute with exercise.This is normal.low heartbeat (heart rate), called bradycardia, is an arrhythmia, or disorder of the heartâs rhythm. Each day, a normal heart beats about 100,000 times, at a rate anyÂ­where from 60 to 100 times a minute. Changes in heart rate caused by activity, diet, medications, and age are normal and common.
