McKittrick-Wheelock Syndrome Presenting with Acute Kidney Injury and Metabolic Alkalosis: Case Report and Narrative Review

Figure 1

Electrocardiogram performed on first visit. The U waves are seen in precordial derivations (arrows). In V2-V3-V4, they are fused to the end of the T waves. In V5-V6, inverted T waves are followed by subtle U waves. The pseudo-prolonged QT interval actually results from the measurement of a long QU interval. HR = heart rate; bpm = beats per minute; QT = QT interval; QTc = corrected QT interval; ms = milliseconds.
