SD standard deviation, SpO 2 percutaneous oxygen saturation 3.2 Heart Rate Evaluation As shown in Table 3, heart rate at CCTA was 65.4 ± 8.0 beats/min, which was significantly lower than the value of 77.1 ± 9.8 beats/min before administration of the study drug (paired t test: p < 0.0001). The heart rate-lowering rate, defined as percent change from the baseline to Ceritinib cell line CCTA, was −14.46 ± 8.4 % and the reduction rate showed statistical significance (paired t test: p < 0.0001) as did the mean heart rate at CTTA. The heart rate then rapidly recovered toward the baseline value at approximately
6 min after completion of the study drug administration (Fig. 3).
