Woldemar Mobitz and His 1924 Classification of Second-Degree Atrioventricular Block

Woldemar Mobitz and His 1924 classification of second-degree atrioventricular block.

Woldemar Mobitz, an early 20th century German internist, analyzed arrhythmias by graphing the relationship of changing atrial rates and premature beats to AV conduction. Through an astute mathematical approach, he was able to classify second-degree atrioventricular block into 2 types, subsequently referred to as Mobitz type I (Wenckebach) and Mobitz type II (Hay). Type I AV block was most often...

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...

A rare cause of trauma in the elderly: Mobitz type-II second-degree atrioventricular block.

Cardiac rhythm problems are frequently seen in the geriatric population, and they can experience trauma after syncope. A 78-year-old female was examined for thoracic trauma after falling. With a history of beta-blocker use, arterial blood pressure measured 60/30 mmHg and pulse rate was 30 bpm. Electrocardiogram showed a Mobitz type-II second-degree atrioventricular block. There was no response ...

Second-degree Atrioventricular (Mobitz 1) Heart Block in a 52-hour-old Newborn: A Very Rare Case Report

Background: Cardiac conduction disorders are rare syndromes in neonates and children. According to the literature atrial septal defect, especially ostium secundum type, is associated with atrioventricular (AV) block. Wenckebach conduction heart block is very rare in a neonate; however, there is a dearth of research on the prevalence of this type of heart block regarding the neonates and pediatr...
