Dr Oliver Segal, Consultant Cardiologist, London

Oliver Segal qualified from King's College Hospital, London in 1995 and trained in cardiac electrophysiologyCaring for patients with heart rhythm disorders, palpitations, blackouts and patients potentially at high risk of dying suddenly due to cardiac arrest. and device implantation at St Mary's and St George's Hospitals in London. In 2004 he won 1st prize in the prestigious Heart Rhythm Society Young Investigator Award for Clinical Research in San Francisco, USA for his work on ventricular tachycardiaAn abnormally fast heart rhythm developing in the ventricles, the pumping chambers of the heart which he undertook at the National Heart & Lung Institute, Imperial College, London. He was then selected for and completed a fellowship in Pacing and Electrophysiology at Professor George Klein's world famous laboratory in London, Ontario, Canada.

Dr Segal is a Consultant Cardiologist at The Heart Hospital, University College London Hospital and The Harley Street Clinic hospitals, London. He has been practising electrophysiology for 10 years, and he has performed 1000 ablations and over 600 device implantation procedures, including pacemakers, defibrillatorsDevices used for defibrillation, which involves giving a controlled electric shock to restore normal heart rhythm in cases of cardiac arrest. (ICDs), biventricular pacemakers and left atrial appendage occlusionThe blockage of a passage, canal, vessel or opening in the body. devices (Watchman). He has published widely on all aspects of arrhythmias and has presented his work at numerous national and international conferences. His special interests include atrial fibrillationA common abnormal heart rhythm causing a rapid, irregular pulse and failure of the upper chambers of the heart (atria) to pump properly. Abbreviated to AF., ventricular tachycardiaAn abnormally fast heart rhythm developing in the ventricles, the pumping chambers of the heart , ablation and cardiacRelating to the heart resynchronisation therapy.

Personal treatment philosophy: Patients deserve the best quality healthcare provided by highly trained professionals. I am proud to be able to offer the state of the art in treatment for arrhythmiaAny form of disturbance to the heart's normal regular beat patients and especially to have been the first to offer the laser balloon to patients in the UK.

Abbreviated to AF., every treatment approach has its set of potential complications. As with all surgical approaches, complication rates are related to surgical skill, experience and the selected method. Although complication rates are low, some complications are more serious than others.

    Who can have Ablation for Atrial Flutter?

    Almost anyone can undergo ablation for typical atrial flutterAn abnormally fast but regular heart rhythm due to disturbances in the biological electrical system of the atria of the heart. It is a type of supraventricular tachycardia. Patients must be able to lie flat without discomfort. Some patients may need to be able to tolerate a general anaestheticAny agent that reduces or abolishes sensation, affecting the whole body.. Most patients will have the ablation performed whilst taking bloodA fluid that transports oxygen and other substances through the body, made up of blood cells suspended in a liquid. thinning medications such as warfarinAn anti-coagulant drug used to treat and prevent abnormal blood clotting., usually for at least a month beforehand and so a previous history of bleeding may preclude this.

    What is Atrial Flutter and How is Atrial Flutter Diagnosed?

    The normal beating of the heart is controlled by electrical impulses. Atrial flutter is an abnormal electrical short circuit that results in a rapid or irregular heartbeat. It can occur in either the left or right atriumOne of the two upper chambers of the heart. of the heart, which are the top 2 chambers in the heart.

For many patients undergoing this procedure it will mean that they are able to come off their anti-coagulants, betablockers and anti-arrhythmic drugs.

    Atrial fibrillationAbnormally fast and uneven contractions of the heart muscle, so that blood cannot be pumped efficiently is the most common heart rhythm disorder in the developed world and it is estimated that 1 million people in the UK have this condition. Atrial fibrillation, or AFAn abbreviation for atrial fibrillation for short, is the leading cause of strokeAny sudden neurological problem caused by a bleed or a clot in a blood vessel. in the country and may also cause heart failureFailure of the heart to pump adequately. in some patients. It results from abnormal electrical impulses in the top chambers of the heart, the atriaThe two upper chambers of the heart., which can lead to rapid, irregular palpitationsThe feeling when you become aware of your heartbeat - when frightened, for example., breathlessness, chest pain, light-headedness and tiredness.
