Intermittent LBBB?

Michael Bennett said:

Hello:

I'm a mid-forties male. Two years ago I was given a physical exam by a GP which included an EKG.
It showed LBBB. I just had another physical exam by the same doctor which included an EKG but this
time it did not show any LBBB. The doctor said the LBBB is presently gone and that I have
intermittent LBBB. Does that sound right?

It is possible that your LBBB is intermittent or rate dependent.

Could the machine have been mis-set either or both times?

No.

If it really is intermittent, I guess I can get it again next week, right?

Correct. Or you could have it when your heart rate is higher.

Why all this strange activity in my heart?

It is not activity but a dysfunctional left bundle of His purkinje fibers.

Thank you.

You are welcome, Mike.
