Beware of the “Highly Sensitive” Troponin

  • Post category:Cardiology

In 2009, “highly sensitive” troponin assays became available. These assays can detect the presence of troponin at much lower serum levels compared to traditional troponin assays. “Highly sensitive” troponins have a higher sensitivity and negative predictive value, but lower specificity, when compared with traditional troponin assays.

Criteria for Discriminating Ventricular Tachycardia from SVT with Aberration

It can be especially difficult to distinguish between ventricular tachycardia (VT) and supraventricular tachycardia (SVT) with aberrant conduction. Fortunately, if the patient is unstable, the initial treatment for both rhythms is synchronized electrical cardioversion.

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.
