Have res cardiomyopathy from cardiac sarcoid found from card biopsy developed arrhythmias may need defib implanted ..does the defib shock hurt me?

Hmmmm...: Ventricular fibrillation usually causes rapid unconsciousness, so you might be unaware of the event. However, if you're still conscious at the time of the shock, you may feel it. People vary so widely in their pain threshold and tolerance that it's not possible to predict for you. Since the alternative is "Sudden Cardiac Death", a brief, uncomfortable sensation is worth enduring. Best wishes
