Abstract
Congestive heart failure is a highly fatal disorder with a .5 year survival
rate less than 50%.
Introduction and Aim of the Work. J
Many patients with congestive heart failure die suddenly and
unexpectedly and most of these sudden deaths. are probably arrhythmic in origin.
However, several studies confirm that short term survival in severe congestive
heart failure is related to both functional status and the presence of high grade
ventricular arrhythmias. Those patients with markedly impaired left ventricular
function in whom complex ventricular arrhythmias detected by 24 hours
ambulatory Holter monitoring are at the highest risk of sudden death. Thus it
can be argued that antiarrhythmic therapy is indicated in those patients although
there is no evidence that antiarrhythrnic therapy prevents sudden death.
