Table 1. Heart Rate, QT, JT, and JTc Measurements

Values are mean ± SD.

*P < 0.01 in intergroup comparison.

QT = the interval from the beginning of the Q wave to the end of the T wave; JT = the JT interval, reflecting the phase from the end of the electrocardiographic ventricular wave complex to the end of the T wave; JTc = heart rate corrected JT interval.
