T wave alternans
Key Points Definition: T wave alternans (TWA) is a phenomenon where there is a beat-to-beat variation in the amplitude or morphology of the T wave on the ECG, without affecting…
STAT ECG Diagnoses: abnormal T waves and T wave alternans
An elderly male presents with weakness and lightheadedness to his primary care physician. He is referred to the ED after the following ECG is obtained:
