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...

669 September 2015 A the overall pulmonary artery catheter (PAC) use has decreased, it remains a valuable tool in select patients. PAC insertion may result in ventricular or supraventricular dysrhythmias due to contact of the catheter with the cardiac chamber walls. The use of balloon-tipped catheters during insertion serves to increase the catheter tip surface area, thereby mitigating applied ...

background: isolated right bundle branch block (rbbb) is a common finding in the general population. the atrioventricular node (avn) artery contributes to the blood supply of the right bundle branch. our hypothesis was that the anatomy of the avn artery and the pattern of dominancy differ between subjects with and without rbbb. methods: w e retrospectively studied the coronary angiography of 92...

I N 1917 Rothberger and Winterberg’ published an electrocardiographic record which depicts the gradual clearing of a defect in conduction affecting the right branch of the bundle of His. An attempt to cut this structure in the course of an experiment on a dog blocked it only temporarily. Fortunately, one of the tracings taken spanned the period during which the injured bundle gradually recovere...

Four cases of complete right bundle-branch block and one case of atrioventricular heart block, all occurring within three generations of the same family, are described. The 4 patients with bundle-branch block had no symptoms, whereas the patient with atrioventricular heart block suffered Adams-Stokes attacks from the age of 13 and died at 47 years of age. A 33-year-old man with bundle-branch bl...

Atrial fibrillation is one of the most frequent arrhythmias diagnosed in clinical practice and it is also relatively common in dialysis patients. Atrioventricular and intraventricular conduction disturbances are less investigated in hemodialysis patients and data about their prevalence are insufficient. The objective of this study was to determine the prevalence of atrial fibrillation, atrioven...
