Second-degree atrioventricular block.
1) While it is possible only one type of second-degree AV block exists electrophysiologically, the available data do not justify such a conclusion and it would seem more appropriate to remain a "splitter," and advocate separation and definition of multiple mechanisms, than to be a "lumper," and embrace a unitary concept. 2) The clinical classification of type I and type II AV block, based on pr...
متن کاملSecond-degree AV block.
Second-degree AV block includes a variety of conduction patterns of variable prognostic significance. Careful analysis of the pattern of PR and R-R intervals, the QRS axis and duration, as well as the presence or absence of structural heart disease should allow the medical director to assess the applicant's risk for life insurance.
متن کاملBradycardia-dependent bundle branch block during Mobitz I second degree heart block.
B radycardia-dependent bundle branch block is a relatively infrequent form ofrate-dependent bun-dIe branch block. When it occurs in the setting of Mobitz I second degree heart block, it must be differentiated from ventricular escape and from Mo-bitz II block, both of which are much more common causes of wide QRS complexes. The differential diagnosis is important since Mobitz II block has a poor...
متن کاملProfound first-degree atrioventricular block.
To cite: Akhtar W, Rathod KS, Alexander J, et al. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013010474 DESCRIPTION We present a case of profound first-degree heart block with the longest reported PR interval (640 ms). The aetiology of extreme first-degree block in our case was multifactorial, due to senile conductive system fibrosis, hypothermia and digoxin ...
متن کاملElectrophysiologic studies on Mobitz type II second-degree heart block.
SUMMARY Experimental studies were carried out in animals with intracellular and extracellular electrodes used to record simultanieously from the atrium, atrioventricular (A-V) node, bundle of His, bundle branches, Purkinje fibers, and ventricles to deteimine the site of conduction delay and block in Mobitz type II second-degree heart block. Type II block with block occurring within the His-Purk...
