Key result
Irregular bradycardia with variable QRS morphology requires an advanced differential diagnosis in elderly dyspnea.
Why the study?
Bradycardia with irregular rhythm and varying QRS morphology presents a diagnostic challenge requiring detailed differential diagnosis.

Population
A 92-year-old male patient presenting with shortness of breath
Design
Case report
Broaden differentials for irregular bradycardia with varying QRS in dyspneic elderly patients; this case leaves open further characterization of such rhythms.
We describe the case of a 92-year-old male patient presenting with shortness of breath and an electrocardiogram showing bradycardia with irregular rhythm and varying QRS morphology. A differential diagnosis is discussed. (Level of Difficulty: Advanced.)
