A more important question is why Mr. Morosini died from sudden cardiac arrest (SCA)? SCA is preventable. Microvolt T-Wave Alernans (MTWA) can determine who is susceptible to SCA. It is non-invasive (sensors placed on one's torso), takes a half-hour to perform, and has been CE approved for years. NASA uses MTWA on astronauts.
