Figure 2From: Cardiac implications of hypoglycaemia in patients with diabetes – a systematic reviewEffect of experimental hypoglycaemia on QT interval. Typical QT measurement with a screen cursor placement from a subject during euglycaemia (a), showing a clearly defined T wave, and hypoglycaemia (b), showing prolonged repolarization and a prominent U wave. Horizontal: 799 ms epoch, vertical: 1.33 mV full scale (adapted from Marques et al. [55]).Back to article page
