Arrhythmia

An arrhythmia is an irregular or abnormal heartbeat.
You pulse rate is the number of heart beats per minute.

The heart’s electrical system triggers the heart beat. A normal heart rhythm indicates that the electrical activity within the heart follows a normal pathway. A regular normal heart rhythm is between 60-100 beats per minute.

A fast heart rhythm is referred to as a tachycardia and suggests a rate greater than 100 beats per minute.
A slow heart rate is referred to as a bradycardia and suggests a rate less than 60 beats per minute.

An arrhythmia may be silent and not cause any symptoms. It can be detected by checking your pulse, listening to the heart or by performing tests that monitor your heart rhythm.
Palpitations, breathlessness, fatigue and chest pains are commons symptoms of
arrhythmias.

Arrhythmia can occur as a result of: an underlying heart condition; a complication of heart surgery; other medical conditions.
