WebTo test for the false-negative rate, they imputed a slope so that there was a 10 msec prolongation at supratherapeutic concentrations. Results from 1000 simulated studies showed a false-negative rate of 6.5%. In the same manner, 1000 studies were simulated under the assumption of a true effect of 3 msec at the supratherapeutic dose. WebEKG abnormalities were frequent and included nonspecific ST-T changes (30.9%), possible left ventricular hypertrophy (5.4%), and supraventricular arrhythmias (1.3%). A QTc ≥440 msec was found in 15.3%, while a QTc ≥460 msec was found in 5.3%. Mean ± SD QTd was 34.2 ± 14.7 msec and QTd ≥40 msec was frequent (38.1%). Neither the ...

PR segment: … WebNov 1, 2024 · Normal PR Interval. A normal PR interval is 0.12 to 0.2 seconds. This corresponds with four to five ECG printout squres. Any result of or between 120 to 200 milliseconds is considered normal. This shows that electrical activity is running smoothly from the sinoatrial node to the ventricles.
