About Dr Jeremy Chow

Dr Jeremy Chow is a cardiac electrophysiologist and device specialist with expertise in complex cardiac device management, catheter ablation for atrial fibrillation and ventricular tachycardia, cardiac resynchronisation therapy (CRT), and stroke prevention in atrial fibrillation. He completed his subspecialty fellowship at Kerckhoff Klinik, Bad Nauheim, Germany.

Dr Chow graduated from the National University of Singapore in 2001 and completed basic specialist training in internal medicine, obtaining his Master of Medicine and MRCP (UK and London). He was certified as a cardiologist in 2010 following advanced specialist training at Changi General Hospital and the National Heart Centre Singapore. He was awarded a Ministry of Health Health Manpower Development Plan (HMDP) scholarship for subspecialisation in cardiac implantable electronic devices and electrophysiology in Germany, completing his fellowship under Dr Johannes Sperzel at Kerckhoff Klinik. He has served as Consultant Cardiologist at Changi General Hospital and Clinical Lecturer at the Yong Loo Lin School of Medicine, NUS, and remains a Visiting Consultant at the National University Hospital Singapore.

Areas of Clinical Focus

  • Electrophysiology studies and catheter ablation — radiofrequency, cryotherapy, and pulsed field ablation for atrial fibrillation and ventricular tachycardia
  • Implantation of leadless pacemakers, implantable cardioverter defibrillators (ICD), and cardiac resynchronisation therapy defibrillators (CRT-D)
  • Complex cardiac device upgrades and lead extractions
  • Multipolar left ventricular lead implantation for CRT
  • Stroke prevention in atrial fibrillation with left atrial appendage closure device
  • Management of supraventricular tachycardias and outflow tract ventricular tachycardias
  • Coronary angiography via radial approach
  • Combined pulsed field ablation (PFA) and left atrial appendage occlusion (LAAO) as a single procedure for patients with atrial fibrillation

Media Coverage

Clinical Approach

At AHVC, Dr Chow and the team provide comprehensive atrial fibrillation management, offering patients both catheter ablation and stroke prevention with left atrial appendage occlusion as part of the same care pathway. The practice also sees patients requiring second opinions, including those with complex device complications, uncontrolled hypertension, and familial hyperlipidaemia with severe coronary artery disease.

Frequently Asked Questions

What does Dr Jeremy Chow specialise in?

Dr Jeremy Chow specialises in cardiac electrophysiology and device management. His areas of focus include catheter ablation for atrial fibrillation and ventricular tachycardia, implantation and management of pacemakers and defibrillators, leadless pacemakers, cardiac resynchronisation therapy, lead extraction, and stroke prevention in atrial fibrillation.

What is atrial fibrillation?

Atrial fibrillation (AFib or AF) is an irregular and often rapid heart rhythm (arrhythmia) affecting the upper chambers of the heart. It can cause palpitations, fatigue, and breathlessness, and is associated with an increased risk of stroke. Treatment options include medication, catheter ablation, and stroke prevention procedures such as left atrial appendage occlusion.

What is a leadless pacemaker?

A leadless pacemaker is a miniaturised pacemaker that is implanted directly into the heart via a catheter, without the need for surgical implantation or pacing leads running under the skin. Dr Jeremy Chow performs leadless pacemaker implantation at AHVC.

What is left atrial appendage occlusion (LAAO)?

Left atrial appendage occlusion is a catheter-based procedure to seal off the left atrial appendage, a small pouch in the heart where blood clots are commonly formed in patients with atrial fibrillation. It is used to reduce the risk of stroke in patients who cannot tolerate long-term anticoagulation therapy.
