Had an EKG about 8 months ago. Was perfect. Lately-feeling nervousnes, rapid heartbeat, suddennfear of choking, ect. They said it was panic attacks?

Quite possibly. How bad? Had it before? A panic attack = feeling scared to death. It is an abrupt onset of panic or dysphoria w/ autonomic activation (rapid heartrate, shortness of breath, nausea, sense of choking, cold sweat, etc). Try breathing slowly &/or breathing into a paper bag (in case you're hyperventilating). It usually dissipates in a few minutes but may recur.
