Key ECG Characteristics of Mobitz Type I and Type II AVB

Second-degree AVB is divided into two types, Mobitz type I and type II. It is important for the emergency provider to be able to distinguish between these two types of second-degree AVB, as treatment, disposition, and prognosis can be vastly different.

Comparison of Multifocal Atrial Tachycardia, Atrial Fibrillation and Atrial Flutter
  • Post category:Cardiology

The most common misdiagnoses of Multifocal Atrial Tachycardia are atrial fibrillation (Afib) and sinus tachycardia. Since the treatment of each of these dysrhythmias is different, it is imperative for the emergency provider to correctly diagnose MAT.

Consider Aortic Dissection in Patients with Chest Pain and Ischemic ECGs

In Aortic Dissection, a defect in the aortic intima allows entry of blood into the tunica media. A false lumen develops and can propagate in an anterograde or retrograde direction. Aortic Dissections that involve the ascending aorta (Stanford type A) can cause coronary insufficiency by several mechanisms.
