Ventricular threshold continues to increase
I have been on 3 monthly checks this year because my ventricular threshold is steadily increasing from 1v to 2.9v (in 9 months).
I have a DDD pacemaker for total heart block after surgery for valve replacement and subsequent infective endocarditis.
The cardiologist doesn't seem to be concerned, just says come back in 3 months. Should I be worried?
