The incidence of exercise-induced bundle branch block has been reported as ranging
from 0.2% to 1.1%.

In >3 of every 4 cases, the blocked branch is the left one.

Exercise-induced right bundle branch block implies the existence of a proved coronary
disease,

but the appearance of an exercise-induced left bundle branch block (LBBB) is a controversial
matter raising a diagnostic problem.

The presence of significant coronary artery disease in exercise-induced LBBB is up
to 70%, and it is especially severe,

but in some patients appearance of rate-dependent LBBB is not associated with either
coronary disease or other structural heart disease. Some investigators have described
a subgroup of patients who experienced chest pain that coincided with the first beat
with the LBBB that was very similar to angina; these patients had angiographically
normal coronary arteries.

This condition was termed painful LBBB.

The goal of this study was to analyze the clinical profile and long-term follow-up
of patients with painful LBBB diagnosed during the last 15 years at the nuclear cardiology
laboratory of our hospital.To read this article in full you will need to make a payment
