As many of you in this community are well aware, I have been suffering from troublesome episodes of
sinus tachycardia for quite some time. At the onset of
these incidents, I thought for certain that something was seriously wrong with my heart, but after submitting to numerous tests, it has been determined that my heart is, in fact, healthy, and that my symptoms are caused by anxiety. In order to relieve them, my doctor prescribed me an SSRI, Lexapro, which has greatly reduced their frequency.
