PVCs, NSVT, PACs Lifelong Recreational Endurance Athlete
68 years old. 50+ years of recreational endurance training on bike, rowing, running & Precor AMT. No more running because hip replacement 3 years ago.
Been wearing a Polar H10 chest strap with ECG app designed for Polar H10. PACs (burden ~1-3% w/couplets); PVCs burden <1% but with a few 1 to 8 second runs if NSVT.
Atrial flutter (not afib) ablation 9 years ago.
Zio Patch & Boston Scientific patch over last 9 years similar results.
No documented afib.
SPECT myocardial stress test: 143 bpm (93% predicted max) with PVCs and PACs including couplets.
Echocardiogram: Enlarged left and right atrium (53 "severely" dilated); EF 58% rest & 57% stress. "No significant fixed or reversible defects."
hs-Troponin elevated after workout (38 - 40 -45 - 40 - 35).
EP says CCTA & Cardiac MRI/LGE not necessary. But to give me "piece of mind" regarding fibrosis/scars, he ordered CMR/LGE. No results yet.
EP said I'm cleared to resume long cardiovascular workouts (2+ hours). He said my PREVENT score was 4.1%.
So, I'm still doing the long workouts while wearing a Livenpace ECG monitor which has detected PVCs (burden <1%) including a few runs of 1-8 seconds of NSVT (also on my Zio Patch from 9 years ago); PACs (burden 1-3%) including couplets; SVT (few seconds); no afib, no aflutter.
But, because I know about these arrhythmia, I am experiencing some periodic chest tightness at rest. Trying to determine if it's a result of health anxiety (aka cardiophobia) or something heart related.
EP says: Go for it. No restrictions.
Any thoughts. Any recommendations. Any similar experiences?
Thanks in advance.
68 and want to keep at it a bit longer. 😀
