LV enlargement: The key here is to determine why your left ventricle is enlarged? That's the important data that's missing. Separately, a recording of your heart rhythm (24 hr, 48 hr, 30 days or longer) can help correlate your symptom of "painful protruding heartbeat" with your actual rhythm. From this, treatment, if necessary, can be determined.
