Abstract
A number of publications have claimed that Mobitz type II second-degree atrioventricular (AV) block can occur during sleep apnea. None has provided a definition of type II block used in the articles, and representative electrocardiograms have been generally missing. Despite these reports, the existence of type II AV block during sleep must remain questionable.
Zusammenfassung
In einigen Publikationen wurde behauptet, dass es bei Schlafapnoe zu einem atrioventrikulären (AV) Block 2. Grades vom Typ Mobitz II kommen kann. In keiner dieser Arbeiten wurde angegeben, welche Definition des AV-Blocks Typ Mobitz II angewandt worden war, und EKG-Beispiele (EKG: Elektrokardiographie) fehlen weitgehend. Trotz dieser Berichte bleibt die Existenz eines AV-Blocks 2. Grades vom Typ Mobitz II während des Schlafs fragwürdig.
