An “electrical storm” is a situation in which multiple shocks from an ICD are delivered in a short period of time (more than 3 shocks in 24 hours). This situation corresponds to an urgent situation in which your condition has changed and arrhythmias become very frequent. It justifies rapid treatment to avoid the repetition of arrhythmias and therefore shocks. In general, if you receive more than one shock in the course of 24 hours, you must very quickly contact your doctor or your implantation center because this can be the onset of an electrical storm. An electrical storm requires hospitalization and, often, intravenous treatment or even general anesthesia to stabilize the situation.
