Isorhythmic AVD
Results:
AV Block: Third-Degree (Complete Heart Block)
Key Points Definition: Complete heart block (CHB) is characterized by total failure of conduction from the atria to the ventricles, leading to independent atrial and ventricular rhythms (AV dissociation). Atrial…
AV Block: Second-Degree, High-Grade (Advanced AV Block)
Key Points Definition: High-grade or advanced AV block is a severe form of second-degree AV block, usually associated with a Mobitz II pattern, where multiple consecutive P waves fail to…
Rhythm Interpretation: AV dissociation does not always mean there is a complete heart block
A 64-year-old woman presents to the emergency department with sore throat. The following ECG was obtained at triage:
