Suggest Treatment For Palpitation And Panic Attacks

I have been a little sick. Today I tried to get ready for work in the dark. Power outtage. I teach kindergarten and have been under serious stress. When I got to my car, I had faster heart palpitations. That has been an hour ago. I have panic attack disorder, so I took one of the klonopin and went to bed. It still felt fast after the hour, but not as fast. I took my pulse for 15 seconds on my neck. It was 27, so I think it was 108 for the minute. I am 58, 5'3" and my blood pressure is always low. I have a heart valve that backflows into the ventrical when blood is pumped to the main artery, diagnosed about 4 years ago and had the dye procedure that showed that all of my arteries are clear, at that time. My cholestorol is usually borderline and a little above at times. I do not eat much salt and I usually do not eat that much: cereal, fruits, vegetables, occasional meat, but I do love ice cream and have it a few times a week lately. I did feel weak from the cold I have been fighting. I also took some antiviral drugs for I feared that I was going to have a herpes outbreak. I did not. I take trazadone for night terrors, paxil for depression and strattera for ADHD also. I just took my pulse again. It is still 108.
