I really need someone to put my mind at rest or at least tell me if I should do more. In the past 3 and a half months I have had xray, 3-4 blood tests + heart enzymes test, 2 holter monitors (during which I didn't get the flutters I experience, but felt light-headed and dizzy), had a doctor listen to my heart several times, several ECGs (all came back perfect), doctors assure me that it is all based on anxiety but sometimes it happens out of the blue. The flutters happen for a second and make me take a deep breath. One doctor was listening to my heart while I felt smth like that he didn't say anything until I asked if he had heard it. He said it was a begin pvc. So is that enough or I should request an echo or smth?
