Manhattan Cardiology’s own Dr. George Welch was recently interviewed in New York Daily News (nydailynews.com) to speak about the recent passing of Tom Petty by sudden cardiac arrest. Dr. Welch is quoted as saying:
“Cardiac arrest occurs when your heart abruptly stops beating due to a malfunction in the body’s electrical system,” says George Welch, M.D., a cardiologist with Manhattan Cardiology.
