I am not a runner, but 16 years ago I had SVT, 205 bpm. It was determined that my resting heart rate was too low for drugs. I had an ablation. Three months later the SVT came back (the electrophysiologist has said there was that chance). I had a second ablation. Since then I’ve had PVC’s from time to time. Last May I almost passed out at work from a short fast arrhythmia. My cardiologist thought it might be ventricular tachycardia. In June I had a LINQ loop recorder implanted.
