Heartbeat away from making medical history (Australia)

Marshall Hastings has a very rare genetic heart condition that causes his heart to beat abnormally fast, but what makes him extraordinary is that he still alive. The 10-year-old was pulled from the bottom of a swimming pool by lifeguards after he suddenly and inexplicably sank mid-race during a swimming carnival last October. A combination of cardiopulmonary resuscitation and a defibrillator - which the Botany Aquatic Centre, Australia, had recently installed but never used - saved Marshall from certain sudden cardiac death (SCD). - SMH
