It looks as though we have similar issues. I have been diagnosed with apical hypertrophic cardiomyopathy, ventricular tachycardia, and some myocardial bridging. I have just about every test imaginable the last two years, and so far i'm being treated with drugs. I have worn a holter monitor 4 times, the last being a month long. At the present I have had a loop monitor installed to monitor my heart rhythms 24/7. I could have this in place for 3 years. I believe from this monitoring, my team of cardiologist will be able to determine whether or not I will need an ablation. They seem to be covering all the bases before any more invasive action is taken. Personally, I wish the pace would pick up a little. I'm getting pretty tired of being tired.
