Don’t Skip a Beat!
An arrhythmia is a disorder of the heart rate (pulse) or heart rhythm, such as beating too fast (tachycardia), too slow (bradycardia), or irregularly. One of the most common is abnormally slow heartbeats, a condition known as bradycardia. For most people, a normal resting heart rate is considered to be between 60 to 100 beats a minute; anything less than this may be considered bradycardia.
A slow heart rate is perfectly normal, and even a sign of good physical fitness. Healthy young adults and athletes often have resting heart rates of less than 60 beats per minute. This occurs because high-intensity training makes the heart muscle very powerful, able to pump more blood with each contraction, making fewer contractions necessary.
