A case of florid rheumatoid heart disease with complete heart block is described, and the histopathology of the atrioventricular conducting tissue is described in detail.

Twenty patients with congenital complete heart block (CHB) were monitored with ECG tape recordings while awake and asleep. Episodes of marked ventricular slowing during sleep (R-R greater than 3000 msec., i.e. less than 20 beats/min) were noted in 35% (7/20). Most of these sudden R-R prolongations were 2:1 or 3:1 exit block of the junctional focus. Atrial and ventricular rate changes were mostl...

The development of complete heart block is described in a patient with polymyositis. The implantation of a permanent pacemaker has controlled the heart block, but the progression of the underlying disease despite treatment with relatively high dosage of corticosteroids makes the outlook uncertain.

Complete heart block is a conduction disorder characterized by a random relationship between the atrial and the ventricular activation where the atrial impulses are not conducted to the ventricle. The incidence of complete heart block (CHB) is estimated to be 1 in 15,000 to 20,000 live births [1]. It may be congenital or acquired. The acquired variety is rare during pregnancy as this type is mo...

Atrioventricular block may occur in various acute and chronic diseases pertaining to the myocardium, or the structures surrounding, or in close proximity to the A-V node,' bundle and bundle branches. When atrio-ventricular conduction is disrupted the ventricles are activated by distal pacemakers. Complete heart block usually results in some degree of cardiac insufficiency, manifested as a reduc...

This is a pathophysiological correlation in two cases showing split His bundle potentials. The first case had a history of previous complete heart block and the electrophysiological studies revealed split His potentials with intact A-V conduction. Case two had split His potentials with complete heart block. Serial sections of the conduction system in both cases revealed calcific impingement on,...

background: neonatal lupus erythematosus is an uncommon disease. congenital complete heart block (cchb) usually happens in neonates with maternal systemic lupus erythematosus. the most prevalent presentation of cchbis bradycardiathatcanbediagnosed through an electrocardiogram. case report: here in, we present the case of a full-term male neonate with gestational age of 37 weeks and birth weight...
