Paperback. Condizione: New. Print on Demand. This book, a detailed study of the influence of temperature on heart rate, is the result of the author's extensive experiments on isolated dog hearts. Prior to the author's work, scientists had largely relied on extrapolating data from frog hearts or human observations to understand the relationship between temperature and heart rate in mammals. However, the author demonstrates that the direct application of temperature to the mammalian heart offers unique insights not available through other methods. The book outlines a novel technique for isolating the heart while keeping it alive and perfused with a controlled blood supply, allowing for meticulous manipulation of temperature. The author's experiments reveal that temperature exerts a direct influence on the heart rate of mammals, with higher temperatures leading to faster heart rates and vice versa. This finding challenges the prevailing notion that only a decrease in temperature can slow the heart rate and demonstrates the importance of studying the direct effects of temperature on the heart. The book concludes by emphasizing the significance of understanding how temperature influences heart rate, as it has implications for our comprehension of the physiological regulation of body temperature and potentially abnormal heart rhythms.
