心血管对寒冷反应,是对喜欢冬天游冰冷水的28个人(冰熊们”)中进行研究的。从病史和临床检查证明,除了一个高血压(180/106mmHg)而其他3个舒张压为95mmHg 以外,没有其他异常,当这些人在池旁一间小屋等候未穿衣、身体暴露在冷空气中时,收缩压明显地升高,而舒张压仅轻微上升。过4分钟后,血压又恢复到控制数值。心电图及心向量图描记仍无变化。虽然有几个人的压血都很高,但没有发现左心室肥大的体征,或心血管、脑血管的损害。
The cardiovascular response to the cold was studied in 28 people who like to swim in icy waters in winter (ice bear).
