VanIsle, I was rushed to the hospital by ambulance for irregular heart beat (my wife insisted).
Tests proved that this particular occasion was NOT a heart attack, but I had had one - a "SILENT" one - sometimes in the past, and was not even aware of it.
I am not trying to minimize panic attacks. After all, only the person who experiences can know how it feels.
If I was out of line, I apolgize.
