Dr Gall is a Cardiologist with a special interest in the investigation and treatment of arrhythmia (cardiac electrophysiology), including inherited syndromes. He developed a particular interest in dizzy spells, blackouts and collapses of uncertain cause, which led on to the development of the Neuro-cardiology service at King’s. Working closely with colleagues in neurology, neuro-otology and psychiatry, the clinics now see patients from around the UK and further afield with this problem. All forms of transient loss of consciousness are managed in the service with patients sign-posted to other experts as required. PoTS, inappropriate sinus tachycardia, orthostatic intolerance and other autonomic conditions are a particular focus of the clinic, now being one of the largest in the UK.
