case_images: The initial electrocardiogram (ECG) (Fig. 1) revealed tall, peaked T waves (greater than 10 mm) and a QRS duration of 100 msec.
case_images: Electrocardiogram while potassium was 5.9 demonstrating narrowing of the QRS and less peaked T waves.

case_images: Potassium had dropped to 5.9 by that time. Potassium decreased further to 4.2 after 9 more hours, and the tracing at that time was identical to the normal one taken a week later (Fig. 3).
