Core Tip
Core Tip: A number of publications have claimed that Mobitz type II atrioventricular block (AVB) may occur during sleep. None of the reports defined it and representative electrocardiograms were either misinterpreted or missing. Sleep-induced relatively benign narrow QRS-Mobitz type I AVB must be differentiated from serious Mobitz type II AVB. This depends solely on strict electrocardiograms definitions and behavior of the sinus rate where slowing rules out Mobitz type II AVB even if all the PR intervals are constant. Mobitz type II AVB does not occur solely during sleep when it is absent in the awake state.
