title: ECG changes in response to diuresis in an ambulatory patient with congestive heart failure.
abstract: This case report describes an ambulatory patient with congestive heart failure and peripheral edema who lost 18 lb in response to enhanced diuresis over the course of 1 week. The ECG showed increases in the amplitude of P waves, QRS complexes, and T waves; the duration of P waves, QRS complexes, and QT intervals; and the dispersion of P and QT. The clinical implications of these ECG changes are discussed.
