Hi,
I am a 21 year old male, very physically active (college athlete, cross country and track). I have always had little palpitation related symptoms along with some occasional lightheadedness. About 3 months ago I got a little scared after feeling some of these palpitations while running (which occasionally happened before, but this time it scared me more) I decided to finally have these infrequent symptoms investigated. I have had resting EKG's, an echo, a stress test, a 24 hour Holter, have seen a cardiologist and an electrophysiologist, and am currently wearing a 30 day event monitor. . My echo showed no structural damage (DCM, HCM, valve abnormalities, etc), my 24 hour Holter just showed some isolated PACs and PVCs (16 PACs, 3 PVCs), my resting EKG's just showed RSr, my stress test was normal, the event monitor has helped us catch a couple PACs and PVCs I felt, along with a few brief sinus pauses while sleeping. My EP has looked at all my EKG's and said I don't show signs of Brugada, CPVT, ARVD, and he doesn't seem concerned with Long QT. However, I still am. Based on all this (palpitations during/post running, no fam. hist., no syncope, borderline QTc) what do you think about the possibility of me having LQT? Would you say it is a valid concern, or should I listen to my EP and not worry about it? Here are the EKG numbers:
404/445ms 73bpm, context: ER visit for palpitations (May ’12)
412/453ms, 71bpm, context: 24 hour Holter (April ’12)
412/448ms, 71bpm, context: visit to GP over palpitations, routine EKG (March’12) same visit, literally like 30 seconds later. They just ran it for about a minute and got a couple EKG strips.
414/427ms, 64bpm, context: visit to GP over palpitations, routine EKG (March’12)
380/398ms, 66bpm, context: ER visit for dehydration episode after long run in heat. (July ’11)
