The only purpose of an ICD shock is to terminate a dangerous cardiac arrhythmia. Shock is not pleasant and your doctor will coordinate your device and medications to minimize the chances of shock. Scientific studies have suggested that most people describe the shock as strongly uncomfortable and moderately painful. Nonetheless, the experience of shock can be unsettling personally, and to those around you. Patients may feel a wide range of emotions. Most patients are sensitive to the view of others. However, ICD patients may also underestimate how much others are sensitive to a medical situation and recognize that it is not directly under your control. Consequently, embarrassment is rarely reported by anyone after experiencing an ICD shock.
