1 A normal adult resting heart beat is between 60-100 heartbeats per minute. 2  Some experienced athletes may see their resting heartrate fall below 60 beats per minute. 3  Tachycardia refers to the heart beating too fast at rest-over 100 beats per minute.
Pulse. 1  The pulse measures the number of heartbeats per minute. 2  A normal pulse in adults is between 60 and 100 beats per minute. 3  Bradycardia means the heart beats slowly (fewer than 60 times a minute). 4  Tachycardia means the heart beats very fast (more than 100 times per minute).
