Thanks to all regarding LBBB life expectancy. The NIH article was and was not helpful because it says people with my condition, male or female, have not been studied. I have heart failure due to complete LBBB (His-Purkinji) location. No heart disease or other morbidity concerns. EF 35%. I recognize that a CRT may be in my future should my EF go below 29% and insurance will then cover it. Cardio Rehab workouts raise my PVCs to frequent occasions with mild exercise and include clustered quadrilles and triplets depending on the day. These clustered PVCs are to be avoided.

Thanks for the information. I had a myocardial infarction August 17th and survived. I am waiting to find out what it did to my EF and so on. My cardiologist wouldn't talk to me after the ER visit. I have questions. The cardiologist had her nurse read aloud to me over the phone the cardiologists interpretation of the tests they did at ER. I can't get a new cardiologist to talk to me my only approved cardiologist care allowed by my insurance until 12-18-24.

Looking for a new cardiologist for the New Year when I will be on Medicare and have some choice.
