Key result

ECG aberrancy aids in identifying underlying cardiac diagnoses during challenging clinical presentations.

Key Points

To illustrate how transient aberrant intraventricular conduction on an electrocardiogram can expose an underlying rhythm disorder and guide accurate diagnosis.
Clinical and electrophysiological assessment of diagnostic 12-lead electrocardiogram tracings in a clinical presentation.
Aberrant conduction patterns revealed distinctive QRS morphology shifts that clarified the mechanism of the arrhythmia.
Electrocardiographic analysis enabled accurate differentiation between ventricular and supraventricular conduction abnormalities without invasive testing.
