Macrovolt T-wave alternans and polymorphic ventricular tachycardia.

A previously healthy 18-year-old woman presented to her local hospital with 3 days of heart failure symptoms. An echocardiogram showed severe left ventricular dilation and global hypokinesis with an ejection fraction of 17%. Her history and clinical evaluation were consistent with an acute virus-induced cardiomyopathy. She had not taken any medications before her presentation, and her initial E...

SELF ASSESSMENT ANSWERS An unusual electrocardiographic abnormality

Q1: What is shown in fig 1 (see p 539), and what is its significance? Figure 1 shows a prolonged QT interval (corrected QT 520 milliseconds) and macroscopic T wave alternans. T wave alternans is defined as a beat to beat variation in the amplitude or polarity of the T wave. Macroscopic T wave alternans is a predictor of malignant ventricular arrhythmias. Microvolt T wave alternans is a validate...
