Second degree AV block Type I (Wenckebach or Mobitz Type I) results from a cyclical and progressive conduction delay through the AV junction. The ECG presents with a cyclical lengthening of the PR interval followed by a dropped QRS - a P wave not partnered with a QRS.
Regular cardiology follow-ups, annual ECGs, avoid dehydration, review AV-conducting medications, and seek emergency care for dizziness or fainting.
Mobitz I block, or Wenckebach phenomenon, is a second-degree AV block characterized by a progressive prolongation of the PR interval on an ECG until a P wave is not followed by a QRS complex, indicating failed ventricular conduction. This pattern occurs in cycles.
