Hello Dr. Since one year my heart start to beat very fast, with dry mouth, dizziness and lose of control and after less than one hour i felt normal. Made ecg and eco and holter and everything was normal. Since one month and half i went to a physilogy doctor and got treatment for my panic disorder(escitalopram and clomipramine hydrochloride) felt much better than before but still have some panic attack in a week once or twice, which take only 20-30 min. But since i had this panic attack since a year Suddenly i feel an electric shock and a sense like squeezing arround my chesht and stomach, is this nornal or happened because of this anxiety ? I got X ray for my chesht and it was normal, liver also normal. Please help.
