ep study could not induce my arrhythmia
hi. i've experienced an arrhythmia/tachycardia for several years now, but it's been very illusive. at my cardiologist's suggestion, i wore an event monitor for about a month, and got some good recordings of it. after looking at the recordings (200+bpm), he suggested that i have an ep study to determine the type of arrhythmia (he predicted it was an avnrt), and an ablation to fix the arrhythmia. i had this procedure yesterday--was on the table for six hours--and he wasn't able to induce ANY arrhythmia. i have a few questions:
1) is it common not to be able to induce an arrhythmia in an ep study? he used several pacing protocols and even adenosine, and couldn't get any evidence of accessory pathways or dual av nodal physiology (according to the report);
2) could the ep study have made the arrhythmia worse? after i got home today, i started having more symptoms than i usually do, even after taking my toprol xl; and
3) is there any reason to believe that a second ep study will reveal the arrhythmia so he can ablate it? are there any additional risks for having another procedure?
