Information & Advice for Arrhythmia Patients


Atrial Fibrillation

Atrial fibrillation (usually referred to as AFib) is an abnormality in the rhythm of the heart (arrhythmia). It involves the upper chambers of the heart, the atria, beating irregularly.


A heartbeat that is too slow is called bradycardia. A healthy heart will beat in a steady and coordinated way.

Brugada Syndrome

In Brugada syndrome the heart is structurally normal, but patients may be at risk of developing a fast heart rhythm due to changes within the ion channels of the heart.

Inappropriate Sinus Tachycardia

Inappropriate Sinus Tachycardia (IST) is a condition in which an individual’s resting heart rate is abnormally high – greater than 100 beats per minute or rapidly accelerating to over 100 beats per minute without an identifiable cause

Long QT Syndrome

Long QT syndrome is a rare condition. Experts would suggest that approximately 1 in 7,000 people are affected but, as it is often never diagnosed, this is only an estimate.

Sudden cardiac arrest

Sudden cardiac arrest (SCA) is a condition in which the heart suddenly and unexpectedly stops beating due to a malfunction in the heart’s electrical system.

Supraventricular tachycardia

Supraventricular tachycardia, frequently abbreviated to SVT, is a rapid abnormal heart rhythm that begins in the upper chambers of the heart.


A heartbeat that is too fast is called tachycardia.

Wolff-Parkinson-White Syndrome

In Wolff-Parkinson-White syndrome (WPW) an abnormal electrical pathway directly connects the atria (the top chambers of the heart) to the ventricles (the bottom chambers of the heart), bypassing the atrioventricular (AV) node.
