Summary

Cardiac pacing which involved stimulating the heart electrically with electrical wires that go into the heart is routine practice in the diagnosis and treatment of heart rhythm problems. Clinically this involved the fields of cardiac pacing and electrophysiology. Patients who are at risk of sudden death because of serious heart rhythms that are a result of malfunction of the electrical system of the pumping chambers of the heart (ventricles) are generally implanted with specialised pacemakers that can defibrillate (shock) the heart if a nasty life threatening rhythm should result. Shocks are painful and in order to try and treat these rhythms without shocks, anti tachycardia pacing is performed (this is routine part of the device), which aims to interrupt the rhythm by stimulating the heart electrically. This does not always work and can destabilise the rhythm leading to a shock. REVRAMP is a novel modification of anti tachycardia pacing which involved stimulating the heart through the defibrillator wires in a different way. It appears to work better and seems less likely to destabilise the heart rhythm, hence can reduce painful shocks.

Conditions

• Arrythmia

Interventions

Type	Name	Description
PROCEDURE	Induced pacing of the heart	Once the defibrillator leads have been inserted or, in the case of a box change, the old leads have been tested as per routine procedure, these pacing leads will be connected to an external pacing stimulator. The test involves electrically pacing your heart at different rates and we will be constantly monitoring you under close clinical supervision. During the test, your heart will be electrically stimulated to beat at a faster rate.
