If a person has no underlying health conditions such as a heart disease but has a severe panic attack which jumps his or her heart rates up to 180 BPM from 80 BPM within seconds, could this sudden, unexpected change in heart rate and/or the adrenaline rush itself kill you? I have read that 200k+ people die per year from sudden death syndrome.
If so, what are the chances of this happening to someone with frequent panic attacks?
