Release of adenosine and lactate from human hearts during atrial pacing in patients with ischemic heart disease.

abstract：BACKGROUND:The right bundle branch block (RBBB) and the bifascicular blocks affect QRS duration in the right precordial leads, which are usually used for QT interval determination. Up to now, there is no clear recommendation how to determine QT interval in patients with RBBB or bifascicular block. HYPOTHESIS:The hypot...
