@entity1164 is responsible for >40% of @entity1 with @entity712 losing their lives. Thus, the prevention of life-threatening @entity943 is a major goal in the management of @entity712 . In several randomized clinical trials, electrical therapy with the @entity737 ( @entity737 ) has proved superior to medical antiarrhythmic therapy in both the secondary and primary prevention of @entity1164 in @entity1 with reduced left ventricular function. In addition to the severity of @entity1002 , the etiology of the @entity296 appears to be a determinant in the benefit derived from this form of electrical therapy. Whereas @entity1 with @entity296 clearly show improved survival with @entity737 therapy, outcome data in @entity1 with @entity296 are less convincing. The major challenge lies in the risk stratification of @entity1 with @entity712 for @entity204 . Catheter ablation is another form of electrical therapy that can help in the treatment of @entity1 with @entity712 . In @entity1 with a @entity591 -mediated @entity296 because of drug-refractory @entity955 with rapid ventricular response, catheter ablation of the atrioventricular node and pacemaker implantation can effectively restore a physiologic heart rate, often with dramatic regression of @entity1002 . In @entity1 with frequent @entity737 therapies because of frequent recurrences of @entity1165 , catheter ablation of @entity1165 can be an effective adjunctive therapy. New catheter ablation techniques and new atrial pacing algorithms can also significantly reduce the @entity955 burden in @entity1 with @entity712 who are particularly susceptible to decompensation because of @entity955 . Pacing for hemodynamic benefit in @entity712 has evolved from dual-chamber pacing modes with optimized atrioventricular delay to biventricular pacing resulting in cardiac resynchronization. This new treatment modality for advanced @entity712 has been shown to result in significant symptomatic and hemodynamic improvement.
