Right bundle branch block during transvenous ventricular pacing.
Cardiac pacing through a transvenous catheter located in the right ventricle usually produces a pattern of left bundle branch block (LBBB). When right bundle branch block (RBBB) occurs during apparent right ventricular pacing, a complication (perforation or malposition of the catheter) has usually occurred. In the patient reported here, uncomplicated right ventricular transvenous pacing produce...
متن کاملRight Bundle-Branch Block and Response to Cardiac Resynchronization Therapy
Cardiac resynchronization therapy (CRT) in appropriately selected patients has been shown to improve cardiac function, heart failure symptoms, and survival.1,2 On the basis of results of large, randomized trials, current American Heart Association/American College of Cardiology/Heart Rhythm Society guidelines recommend consideration of CRT in patients with cardiomyopathy on optimal medical ther...
متن کاملIncomplete Right Bundle-Branch Block
Incomplete right bundle-branch block (IRBBB) usually is thought to be associated with abnormalities of the peripheral Purkinje system. This paper discusses the results of a study of six dogs from the same family and three nonrelated dogs with congenital IRBBB. Cardiac catheterization data were normal, and no evidence or history of cardiac disease was found before or after death. The depolarizat...
متن کاملSafe right bundle branch block pattern during permanent right ventricular pacing: a case report.
We present the case of a 72-year-old male who underwent a permanent transvenous DDD pacemaker implantation for symptomatic complete heart block. The postoperative surface electrocardiogram (ECG) revealed a right bundle branch block (RBBB) pacing pattern with transition in lead V3 and left bundle branch block (LBBB) in D1, suggesting a malpositioned ventricular lead in the left heart. Malpositio...
متن کاملSite of antegrade and retrograde functional right bundle branch block in the intact canine heart.
The purpose of this study was to determine the site of conduction delay or block in situ during antegrade and retrograde functional right bundle branch block (FRBBB) and whether reentrant excitation can occur in both directions in the blocked bundle branch, depending on whether the site of block occurred proximally or distally. Studies were performed in 20 adult mongrel dogs during cardiopulmon...
