WebMobitz type II is a type of 2nd degree atrioventricular block, which refers to a cardiac arrhythmia that reflects a conduction block at the atrioventricular (AV) node. On an ECG, Mobitz type II can be identified by the presence of intermittent, non-conducted P waves without progressive prolongation of the PR interval.

WebJan 19, 2024 · First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by ECG changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG.
