UMMC Cases Part II: Grouped Beats, Slow VT, and Diffuse ST Elevation

UMEM Potpourri ECG Cases with Dr. Amal Mattu

HPI

A 63-year-old man presents with shortness of breath. His ECG shows an unusual rhythm with repetitive groups of two beats separated by pauses.

Before watching this week’s workout, review the ECG carefully and consider:

    1. What is your differential diagnosis for this grouped beat pattern?
    2. Is the first beat of each pair premature, or is it an escape beat?
    3. What does this rhythm suggest about the function of the sinus node?
