What Causes Tremors In Body With History Of Wolff Parkinson White Syndrome?

Hi, I've been experiencing a shaky, tremor type feeling off and on over the past year. None of my blood tests are showing anything, but I'm experiencing it right now and just checked my bp at one of those kiosks at shoppers drug mart. My bp is 145/104 and my pulse is 96. I have a history of Wolfe Parkinson White Syndrome which was corrected when I was 18. I am currently 34 years old, take 20mg of Prozac daily and 20mg of losec...I took 2 benadryl this morning for allergies and other than being shaky (which is a really icky feeling), feel good now. Not stressed or anxious, just curious. Thanks in advance. Tracy
