LBBB and Training

Recently had an EKG and they found a Left Branch Bundle Block (LBBB). I had an MI and a stent five years ago, but no problems until now. Is there any relationship between this sort of thing and weight training? Is there anything I can do to mitigate the effects (although I don’t really know what the effects are)?

You state, “no problems until now” – what problems are happening now? Why did you get the EKG done?

It was a routine follow up appointment with my cardiologist. I was going to have a stress echo. They started with an EKG and identified the LBBB. I’m now doing it all, i.e.14-day monitor, sonogram and a CAT scan in a few weeks. I’m not particularly symptomatic, although I have had some light-headedness that I was told might be related to Tirzepatide. Otherwise, I have been lifting twice a week and Jiu Jitsu three times a week and feeling good.

I should add that I have had EKG’s over the last few years, and the LBBB was not identified. Whatever this is, it arose in the last year.

Hi,

This is getting a bit into the weeds for a forum discussion, but if you had a routine follow up with your cardiologist and have not been experiencing any changes, new symptoms, or limitations, I am not sure that launching an extensive evaluation for LBBB is necessarily needed – but I can’t speak to all of the pertinent details in your specific situation that may be influencing the cardiologist’s recommendations.

However, LBBB can arise for a number of reasons, including ischemic heart disease. To your original question, while it is possible for people to have exercise-induced LBBB, this is not something that I would attribute to exercise in your situation with the MI history, nor is there any specific exercise adjustment that needs to be made as a result of finding it, assuming you are tolerating your training well.

Thanks. I was curious about the training relationship question. Appreciate the input as always.
