Managing the risk of sudden cardiac death in non-ischemic patient ( wearable Cardioverter-defibrillator )
Those are ejection fraction less than 35%, the presence of nonsustained VT or frequent PVCs or a high PVC burden, and prolonged QRS duration. Those 3 factors have been shown time and again, both in meta-analyses of trials and also in subgroup analysis of the major trials, to predict the higher risk of sudden cardiac death.
Determining the risk of sudden cardiac death
– Ejection fraction < 35%
– High PVC burden
– Prolonged QRS duration
– A 62 years old patient presented with atrial fibrillation with a rapid ventricular response and heart failure .
– Heavy alcohol consumer
– Non-ischemic cardiomyopathy
– Coronary angiogram was clear
– Ejection fraction :25%
– Non-sustained VT
– Potential for improvement in cardiac function
Criteria for the use of a wearable defibrillator in nonischemic cardiomyopathy :
– Low ejection fraction
– Presence of non-sustained VT
– QRS duration of > 120 millisecond s
