Evidently it is a matter of the supposed rate
of heart beats that differentiate one from the other. I guess a high percentage of SD's are just that, sudden death. However, I survived this episode,was in the hospital for another 2 and a half days. This time I was released after taking, and being prescibed Metoprolol, 50 mg. I was OK for about a week, hospitalized again, and this time was put on Mexelitine and Amiodarone.
