Dr Rajappan is a Consultant Cardiologist and Electrophysiologist. He has particular expertise in managing heart arrhythmias – electrical disorders of the heart’s beating rhythm.

He was appointed Consultant Cardiologist at the John Radcliffe Hospital in 2007. Before that, he completed advanced training in managing cardiac rhythm disorders at St Bartholomew’s Hospital, London with pioneering cardiologist and electrophysiologist, Professor Richard Schilling.

Each year he sees and treats hundreds of patients with rhythm disorders such as atrial flutter and atrial fibrillation. One of the key treatments is catheter ablation in which a catheter is inserted via a vein and threaded round to the heart. The heat from an electrode (metal ring) at the tip of the catheter destroys the problem tissue and restores normal heart rhythm. A benefit of this treatment is there is no longer a need for medication.

The patients Dr Rajappan sees will typically have one or more of the following: rapid palpitations, irregular heartbeats, ectopic or ‘skipped’ beats, slow heartbeats, dizzy spells, blackouts, breathlessness.

Diagnosis of their condition is backed up by evidence from the Oxford Private Heart and Lung Centre’s state of the art cardiac imaging suite.
