Because of its high success rate and low morbidity, radiofrequency (RF) catheter ablation has become first line treatment for many arrhythmias. In this procedure, one or more electrode catheters are advanced percutaneously through the vasculature to contact cardiac tissues. A diagnostic study is performed to define the arrhythmia mechanism, and subsequently an ablation catheter is positioned ad...

The 3D cardiac arrhythmia visualization model in this paper was developed to assist medical students and fellows in understanding the underlying electrophysiology of cardiac arrhythmias and their treatments. In this detailed cardiac model, the user can freely move to any position of the heart and observe it from any point of view. A transparent mode is applied to facilitate a more detailed expl...

Increased consumption of fish rich in omega-3 polyunsaturated fatty acids (omega3-PUFAs) is associated with decreased incidence of sudden cardiac death in post-myocardial infarction patients, but is also related to increased incidence of sudden death and arrhythmias in patients with acute myocardial ischemia. This review discusses the possible pro- and antiarrhythmic mechanisms of omega3-PUFAs ...

Patients with tetralogy of Fallot are at risk for ventricular arrhythmias and sudden cardiac death. These abnormalities associated pulmonary regurgitation, right enlargement, a substrate discrete, slowly-conducting isthmuses. Although these arrhythmic events rare, their prediction is challenging. This review will address contemporary assessment prevention strategies. Numerous variables have bee...
