Can anxiety cause a constant irregular heartbeat?

I recently had a heart scare, but after testing the only thing found was a slight leak in my mitral valve. My heart rate is about 60-65 at rest, but as soon as I do anything my heart starts racing. EKG's came back normal, Holter monitor=normal, echocardiogram=normal, slight valve leak CT scan=normal. I was quite the caffeine addict when I had a tachycardia 4 weeks ago and a moderate drinker. I gave up both instantly, but have had no improvement in active heart rate. Before the tachycardia 4 weeks ago I had never had this happen to me. This is quite baffling, any ideas? They already told me I don't have mitral valve prolapse and I am seeing a cardiologist on Wednesday.

You may want to take a vacation from the usual stresses of your life. Just getting off caffeine won't help. You've got to stop all that worrying that you're doing....

This is the way to cured from serious desease like (Cancer, Deprssion, anxiety, Hepatitis B,C, Heart and those deseases that reach at the end limit)

Kindly purchase the audio cassette of Surrah 鈥淎L-REHMAN鈥?recited by Qari Abdul Basit, listen the cassette 3 times in a day (morning, afternoon, evening) before you start listening, close your eyes, feel your self in front of GOD and then hear it with greater concentration. When the recitation is finished, kindly take a half glass of water again close your eyes and say 鈥淎LLAH鈥?3 times in your heart and then drink the water with closed eyes. So you have to drink water 3 times each after listening the recitation. You have to do it repeatedly for 7 days, 鈥淪HIFA鈥?is from the almighty ALLAH. 鈥淪HIFA MIN-JANIB-ALLAH鈥? if you can not buy Cassette then download from web site www.alrehman.com Thanks
