QT Measurement and Heart Rate Correction during Hypoglycemia: Is There a Bias?
Figure 2
Measurements of the T wave offset from ECG lead II using the semiautomatic slope-intersect method (SI) and manual annotation (MA) method. The two ECGs are from (left side) and at (right side) at the same episode. At the SI method underestimates the end of the T wave compared with the MA method. With the flattening of the T wave at the SI method overestimates the end of the T wave compared with the MA method.
