How will I know if I get shocked?

Most people are aware of getting an ICD shock and each describes the event differently. Those who are awake during a therapy shock describe it as a “kick in the chest.” The shock startles them, but the feeling passes quickly. Some find it fleeting but still distressing. Others find the therapy shock a reassuring reminder that their heart device is protecting them from sudden cardiac arrest. Some people lose consciousness because of a rapid heartbeat, and they are not aware they received a therapy shock.
