Heart arrhythmias are irregular heartbeats. The heart can beat too fast, too slow or irregularly — learn how to recognise the symptoms here.
Long QT syndrome
Long QT syndrome (LQTS) is a disorder of the heart's electrical system that can cause fast, chaotic heartbeats, called arrhythmias.
This condition can disrupt the rhythm of your heart. It can cause palpitations, fainting or, in serious cases, cardiac arrest.
Wolff-Parkinson-White syndrome is a possible cause of tachychardia (occasional or frequent episodes of very fast heartbeats). Learn more here.
Has your doctor recommended you to have a pacemaker? Find out what it is, who needs it and things to consider before and after the surgery.
Bradycardia is a slower than normal heart rate, which can lead to a range of symptoms such as feeling faint, tired or short of breath.
Implantable cardioverter defibrillators
An ICD, sometimes called an ACID (automated implantable cardioverter defibrillator), may be needed if you have an abnormally fast or irregular heartbeat.
Atrial fibrillation (when part of the heart ‘quivers’ rather than beating normally) could lead to a stroke. Know the symptoms and decrease your risk.
An external cardioversion is a procedure to treat an abnormal heart rhythm. It involves connecting you to a defibrillator machine that gives a controlled electric shock to make your heart beat normally again.
Beta blockers are medicines that are used to treat high blood pressure (hypertension), although there can be risks for some people. Find out more about the benefits and risks of using beta blockers.
