P-wave alternans in a patient with hyponatremia.
نویسندگان
چکیده
We describe an unusual electrocardiographic (ECG) case of an alternating P-wave configuration that spares other ECG components. Hyponatremia due to chronic indapamide use was proposed as a plausible cause of this ECG phenomenon because its correction led to the recovery of a steady P-wave morphology.

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...
