8 paź 2024 · A review of the basic ECG features, causes and pathophysiology of Mobitz I AV Block (Wenckebach Phenomenon) with some example ECGs.
Although later re-classified by Mobitz in 1924 as type 1, second degree AV block, the phenomenon still bears the legacy of the person who first documented its presence, long before the advent of electrocardiography .
Second-degree AV block Mobitz type I exhibits the Wenckebach phenomenon, which means that there are ECG signs of gradual exhaustion of impulse conduction. This manifest on the ECG as gradual increase of PR interval before a block occurs.
9 cze 2023 · The initial electrocardiogram (ECG) demonstrated sinus rhythm with intermittent Mobitz type I second degree AV block and cardiac monitoring revealed frequent episodes of Wenckebach phenomenon...
Mobitz type I atrioventricular block in children, adolescents and young adults without overt heart disease or drug intoxication has been considered less significant than Mobitz type II block. In highly trained athletes and some nonathletes it has been presumed to be a benign manifestation of heightened vagal tone.
