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

Case Presentation 
– 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

Summary

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
