I recently had an Event monitor for 7 days. It showed 260 episodes of Paroxysmal SVT. They were not sustained, but were extremely frequent, occurring in rapid bursts over several hours on several days. The Cardiologist reassured me that this is not life-threatening, but did recommend an ablation. I am scheduled to have a consult with an Electrophysiologist in a couple of weeks. I did forget to ask him, however, if this kind of non-sustained SVT can still cause symptoms. When I have these 'episodes' I notice increased shortness of breath, some mild chest pressure, and terrible fatigue. My heart is otherwise healthy and free of disease. Do any of you have regular, short bursts of SVT that cause lingering symptoms.
