How does hypothermia affect heart rate

Web1. Vasoconstriction: Cold water causes vasoconstriction, which is the narrowing of blood vessels in the body. This can lead to reduced blood flow and oxygen to the lungs and other parts of the body. As a result, one may experience shortness of breath, as the body struggles to get enough oxygen to its tissues. 2. WebBackground: In congestive heart failure (CHF), a low body temperature at hospital admission predicts in-hospital mortality. We hypothesized that a postdischarge reduction in body temperature predicts early CHF rehospitalization and death. Methods: We reviewed the records of 198 patients discharged after CHF hospitalization. We categorized the patients …
