The normal range and determinants of the intrinsic heart rate in man.

چکیده
Jose and Collison published a study on the normal range and the determinants of intrinsic heart rate in man in Cardiovascular Research in 1970 [Jose AD, Collison D. The normal range and determinants of the intrinsic heart rate in man. Cardiovasc Res 1970; 4: 160-167)]. The intrinsic heart rate is the heart rate under complete pharmacological blockade. They showed that (i) the resting heart rate is lower than the intrinsic heart rate and that (ii) the intrinsic heart rate declines with age. They also established that the variability in intrinsic heart rate between individuals of the same age is of the same order as the effect of ageing at the population level. This update discusses the relevance of these data with emphasis on sinus node function and autonomic balance. The paper of Jose and Collison was cited more than 200 times. The frequency of citation started to increase more than 10 years after publication.

The impacts of prone position on the blood oxygen saturations and heart rates of preterm infants under the mechanical ventilation
Background: The methods of baby's position are an important critical factor in ventilation and oxygenation of tissues. Although the prone position as one of the recommended position has beneficial effect on the development of premature infants, little research has been done. Methods: In a clinical trial among mechanically ventilated infants, hospitalized in the neonatal intensive care units (N...

Introduction: Recent studies have acknowledged the potential of convolutional neural networks (CNNs) in distinguishing healthy and morbid samples by using heart sound analyses. Unfortunately the performance of CNNs is highly dependent on the filtering procedure which is applied to signal in their convolutional layer. The present study aimed to address this problem by a...

In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...
