Are there any useful investigations that predict which patients with bifascicular block will develop third degree atrioventricular block?

Disopyramide induced second and third degree atrioventricular block in patients with bifascicular block. An acute stress test to predict atrioventricular block progression.
Syncopal attacks in patients with bifascicular block may be due to both ventricular tachyarrhythmias and intermittent atrioventricular block in addition to non-cardiac causes and lead to antiarrhythmic treatment with drugs or pacemaker or both. The acute electrophysiological effect of intravenous disopyramide 2 mg/kg body weight given over five minutes on the His-Purkinje system was assessed in...
متن کاملEditorial: 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 کاملDisopyramide stress test: a sensitive and specific tool for predicting impending high degree atrioventricular block in patients with bifascicular block.
OBJECTIVE To study the value of intravenous disopyramide as part of an invasive electrophysiological study in predicting impending high degree atrioventricular block in patients with bifascicular block. DESIGN An invasive electrophysiological study was performed in the basal state and after the infusion of disopyramide (2 mg/kg body weight). The progression to high degree atrioventricular blo...
متن کاملCardiac pacing in left bundle branch/bifascicular block patients.
The primary concern in patients with bifascicular block is the increased risk of progression to complete heart block. Further, an additional first-degree A-V block in patients with bifascicular block or LBBB might increase the risk of block progression. Anesthesia, monitoring and surgical techniques can induce conduction defects and bradyarrhythmias in patients with pre-existing bundle branch b...
متن کاملIncidence and site of atrioventricular block in patients with chronic bifascicular block.
Four hundred fifty-two patients with chronic bifascicular block and initially intact atrioventricular (AV) conduction were detected, studied, and prospectively followed between January 1970 and March 1978. There were 360 males and 92 females, ages 18--93 years (mean +/- SD, 62 +/- 15 years). Follow-up ranged from 29-2804 days (mean 1066 +/- 97 days). AV block (2 degrees or 3 degrees) developed ...
