Coupled Pacing and Coupled Pacing with Concealed Conduction
SINCE their introduction by Lopez and coworkers,' paired electrical stimulation and coupled pacing of the heart have been investigated intensively and have been shown to be useful in slowing the effective mechanical rate of the heart or in causing sustained potentiation of cardiac contraction or for both. A recent symposium on this subject provides an excellent review.2 The techniques, in essen...

متن کاملConcealed conduction: an indication for temporary demand pacing.
A lthough cardiac pacemakers have a proved place in the treatment of chronic heart block,1,2 there have been some differences of opinion regarding the efficacy of artificial pacing in heart block complicating acute myocardial infarction. Second degree atrioventricular (A-V) block can be divided into type I (Wenckebach) and type II ( ‘sI bjt ) . The former is the type usually associated with inf...
متن کاملPacing the Human Cardiac Conduction System
Specialized fiber electrograms were recorded from selected sites along the His bundle and bundle branches during open-heart surgery in 26 patients. The heart was then paced from the same recording sites. Stimuli applied to the proximal His bundle recording site always resulted in His bundle pacing, which was characterized by a stimulus artifact-to-QRS interval which equaled or very nearly equal...
متن کاملThe hemodynamic effect of intrinsic conduction during left ventricular pacing as compared to biventricular pacing.
OBJECTIVES We sought to investigate the effect of intrinsic conduction over the right bundle on the maximum rate of left ventricular pressure rise (LVdP/dt(max)) during left ventricular (LV) pacing compared to biventricular (BiV) pacing. BACKGROUND Simultaneous BiV pacing and LV pacing both improve LV function in patients with heart failure and LV asynchrony. We studied the hemodynamic effect...
