Do Not Confuse Mobitz Type I and Mobitz Type II Atrioventricular (AV) Block

Do Not Confuse Mobitz Type I and Mobitz Type II Atrioventricular (AV) Block
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.

Do not confuse Multifocal Atrial Tachycardia with Atrial Fibrillation

Do not confuse Multifocal Atrial Tachycardia with Atrial Fibrillation
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.

Cardiac Glycosides

Diverse plants are sources of sugarcontaining compounds (glycosides) that also contain a steroid ring and augment the contractile force of heart muscle : cardiotonic glycosides / cardiosteroids, or “digitalis”. If…

ECG Interpretation

Approach all EKGs systemically. Always note: rate, rhythm, QRS axis, complexes and intervals, chamber enlargement, ischemia/infarction, compare with prior EKG.
