Editorial: Prognosis of Patients with Chronic Bifascicular Block
OF ALL RECENT conceptual advances in electrocardiography, few, if any, are as popular as the concept of a trifascicular conduction system distal to the bifurcation of the His bundle.' The wide appeal of the trifascicular concept is understandable. The distinct morphological electrocardiographic patterns of various fascicular blocks are easily recognizable even to a nonexpert. The schematic diag...
متن کاملCARDIAC COMPLICATIONS IN SURGICAL PATIENTS WITH BIFASCICULAR BLOCK 343 The Risk of Cardiac Complications in Surgical Patients with Bifascicular Block* A Clinical and Electrophysiologic Study in 98 Patients
Ninety-eight patients with ECG evidence of bifascicular block who had undergone general anesthesia and surgery have been followed up. His bundle electrogram was recorded in all patients prior to the surgery. On the basis of electrophysiologic studies, patients were classified in two groups: normal H-V group (47 patients) and prolonged H-V group (51 patients). The prolonged H-V group presented a...
متن کاملSurgical bifascicular block.
Electrophysiological studies were performed in 18 patients who developed bifascicular block after repair of ventricular septal defect (VSD) or tetralogy of Fallot (TF). Two had transient complete heart block (CHB) in the immediate postoperative period. The P-A intervals were normal in all. A-H and H-V intervals were prolonged in three and four cases, respectively. Atrial pacing at progressively...
متن کاملSignificance of chronic bifascicular block without apparent organic heart disease.
Eighty-six of 452 patients (19%) with chronic bifascicular block were found to have no clinically apparent associated organic heart disease (OHD) and were defined as having primary conduction disease (PCD). Comparison of patients with PCD and OHD revealed a significantly lower incidence of the following clinical variables in the PCD patients (p less than 0.001): exertional angina, dyspnea, cong...
متن کامل[Novel predictors of progression of atrioventricular block in patients with chronic bifascicular block].
INTRODUCTION AND OBJECTIVES Patients with chronic bifascicular block (BFB) can progress to advanced atrioventricular block (AVB), especially when syncope or a prolonged HV interval is present. It is possible that other variables could help identify patients who would benefit from prophylactic pacemaker implantation. METHODS The study involved 263 consecutive BFB patients seen at a single cent...
