Thanks for posting your story, slynnb. I experienced Tachycardia, but while running. For me, simply breaking into a walk would get it to stop. I had the good fortune of getting referred to a cardiologist who diagnosed PSVT. I tried blocker med’s but stopped due to heavy fatigue. I got evaluated for an ablation but the EP said my episodes were too short to catch for electrical mapping. I’ve reluctantly stopped running as my solution to avoiding PSVT.
