Cardiac arrest

Cardiac arrest or heart failure was the term for one's heart stopping. Many things could cause failure, such as a physical blow, an electrical pulse and shock. (TV: The Shakespeare Code, The Power of Three)

For as many ways the heart could fail, there were ways in which it could be restarted again. Defibrillators were a common means. (TV: The Power of Three)

Resuscitation was another way; however, species with a binary vascular system would require both hearts to be restarted at the same time. (TV: Smith and Jones)
