Corrected QT interval (QTc) prolongation in humans is usually predictable based on results from preclinical findings. This study confirms the signal from preclinical cardiac repolarization models (human ether-a-go-go-related gene, guinea pig monophasic action potential, and dog telemetry) on the clinical effects on the QTc interval. A thorough QT/QTc study(More)
Sonar sensors are widely used in mobile robots applications such as navigation, map building, and localization. The performance of these sensors is affected by the environmental phenomena, sensor design, and target characteristics. Therefore, the readings obtained from these sensors are uncertain. This uncertainty is often modeled by using Probability(More)
The rat precardial region was exposed to single 30-minute and course radiations with pulse ultrasound at 2640 kHz before and after experimental myocardial infarction. Ligation of the left coronary artery caused an increase in 99mTc pirphotech accumulation by 243.4% as compared with the controls. Single and course ultrasounding after left coronary ligation(More)
Dynamics of heart rhythm variability (HRV) according to 24-h Holter monitoring of ECG was studied in patients with chronic IHD with paroxysmal cardiac fibrillation (PCF) and controls in response to unfavourable medical weather types and high geomagnetic activity. In unfavourable meteorological conditions IHD patients with PCF show attenuation of a general(More)
