Heart palpitations while fasting

I began fasting because my blood pressure was through the roof... Perhaps brought on by anxiety... This has happened before.

I read that fasting can help bring down blood pressure.

I am on my 4th day. When I started my blood pressure was 168/95. Now it is a bit lower... 131/92.

I feel bouts of extreme anxiety at times during my fast. My heart will race to around 120 beats per minute, I break out in sweats, and it feels as if my heart will explode.

I take only water and Braggs Apple Cider Vinegar. I also supplement with Vitamin C, Heart & Body Extract by Healthy Hearts Club, a Vitamin B complex, and Vitamin E.

Some times I feel great... Others not so great.

This does not feel like a heart attack. Last June I had an EKG and my heart checked out fine. It was then diagnosed as a panic attack... Doc wanted to subscribe medication. I did not take.

Any thoughts? Is my body merely cleansing and repairing itself?

Thanks.
