Small left ventricle & hyperdynamic heart
^(F26 average height and weight, non-smoker & drinker)
Last year I got to meet a cardiologist for my SVT (had it since 2012). While he was doing the echo, he found I have a small left ventricular cavity (diastolic volume 60 ml) with hyperdynamic systolic function (LVEF: 80%). According to him, the diastolic volume should be closer to 80-100 ml. Everything else looked good: normal wall thickness, normal right ventricle, and all my bloodwork is good too. The findings do explain my chronically high resting HR (90ish bpm) and blood pressure (120/87) tho. It was recommended for me to go straight to an ablation (already done, and sadly on the waitlist for a second one) and keep away from beta blockers since I need my high HR.
I feel fine for the most part; I just get exhausted easily, and walking up stairs or doing basic chores like laundry gets my HR in the 160-170s. I get a bit dizzy when I stand up too quickly, and I have passed out from my SVT episodes before. It's been like this for as long as I can remember; I didn't even realize how high my HR actually is until I got a smartwatch and kept track!
I was just wondering if someone else has a similar anatomy to me, or has some more information, since my cardiologist couldn't give me much more than "you have a small but hard-working heart".
