Treatments for arrhythmias

ArrhythmiaEffective treatments exist to control or cure most arrhythmias. This may involve reassurance alone or simple medications, or sometimes procedures to destroy areas of the heart responsible for the problem (ablation).

Some patients may benefit from devices such as a pacemaker to treat slow heart beats, or a defibrillator to treat fast heart beats. In certain cases, devices may be used to treat breathlessness caused by a weak heart (heart failure).

ArrhythmiaSometimes, arrhythmias are the first clue that there may be significant heart disease, such as coronary artery disease, that needs treatment.

For the above reasons, it is very important that patients have access to the appropriate medical and nursing staff to ensure timely investigations are carried out, and the correct treatment given.
