What is tachycardia?

Tachycardia is a condition where the heart beats faster than normal while at rest.
A normal resting heart rate is between 60 and 100 beats per minute. Tachycardia is defined when it exceeds 100 beats per minute.
This can affect how efficiently the heart pumps blood and delivers oxygen to the body.
