Diagnosing and treating disturbances in heart rhythm

What are arrhythmias?

Arrhythmias are disturbances in cardiac (heart) rhythm and are very common.

There are many different types of arrhythmia, including simple extra beats and more sustained rapid beats. Disturbances of rhythm can also sometimes cause slow heart beats. 

The symptoms experienced are varied. Some people may notice simple ‘skips and jumps’, others rapid heart beats. Sometimes dizziness or less commonly blackouts may occur.
