Dr Louisa Malcolme-Lawes Consultant cardiologist and electrophysiologist

Background

Louisa is a consultant in cardiac electrophysiology specialising in both catheter ablation and complex device implantation. Her cardiology training was undertaken at Imperial College Healthcare following a BHF Research Excellence Award funded PhD in Cardiac Electrophysiology and the Autonomic Nervous System. She regularly performs catheter ablation for atrial and ventricular arrhythmias, as well as implanting all types of complex devices including sub-cutaneous ICDs, conduction system pacemakers and leadless pacemakers. She has recently started performing the highly specialised and novel technique of cardioneural ablation for vasovagal syncope.

Louisa works at both Imperial College Healthcare and West Herts Teaching Hospital NHS Trusts, seeing all types of cardiology patients, but specialising in patients with cardiac arrhythmias. As an Honorary Clinical Lecturer at Imperial College she continues to be closely involved in ongoing research studies in both centres and is Principle Investigator at West Herts for the Protect HF study which is a national study of conduction system pacing being run by Imperial College. She also participates in research activities within Imperial College including student vivas and teaching programs, regularly teaching on the BCS Mayo Clinic Cardiology Board Review Course.
