    Heart Issue

    I've had a right bundle branch block for an unknown number of years and doctors have always said it was nothing to be concerned about. Two years ago there was a complete block and a pacemaker was implanted on an emergency basis. The pacemaker is presently pacing the upper chambers approximately 20% of the time and the lower chambers approximately 95% of the time.

    My continuing problem is that upon sustained exertion, I just "hit a wall". There is tightness in my chest, I'm out of breath and I have to stop whatever I'm doing. An example of sustained activity would be walking on a moderate upgrade. It requires me to stop a few minutes every 100 yards. The doctors have done a heart catheterization and that showed no blockages of the heart vessels with the heart looking excellent. I have a St Jude's pacemaker and the company representative met with the doctor, technician and myself to attempt to fine tune the pacemaker to be more effective but that didn't help.

    In June of 2008 I tested positive for Lyme disease and was treated with time release doxycycline for one week. When the problem with the heart occured in October 2011and the pacemaker was implanted, the doctors suspected the electrical problem was the result of having had Lyme disease. However, the infectious disease doctor disagreed with that diagnosis. I take no prescription medications, just an aspirin, a fish oil supplement and a general vitamin daily.

    I'd appreciate any help in determining why sustained activity cannot be tolerated. I'm seventy and in excellent health other than this issue. .

    "The doctors have done a heart catheterization and that showed no blockages of the heart vessels with the heart looking excellent. "

    What about a stress-echocardiogram, as this may/can reveal problems (such as in the heart chambers or valves) only when the heart is put under a load, and of course, compare the difference in heart function (includes wall motion) at rest and stress.

    How's your lungs doing?

    Bundle branch block (BBB) is a relatively frequent finding on the electrocardiogram.
