关于正常人左、右上肢血压的差异历来众说不一,或谓相差5mmHg或谓10～20~+mmHg等,使临床工作者无所适从。传统认为,由于右侧肱动脉解剖位置的缘故致使右侧血压高。在高血压普查时亦强调以右上肢血压测值为准。近年有人也以肱动脉位置的差异为理由认为左侧血压高。现就上述问题及其临床意义探讨如下。 对象和方法 对本院内科门诊就医者无选择地测量左、右上肢血压(间隔3分钟)。剔除大血管病变及两侧血压都超过140/90mmHg的测量对
About the normal left and right upper limb blood pressure differences have always been different, or that a difference of 5mmHg or that 10 ~ 20 ~ + mmHg, so that clinicians know what to do. Traditionally, the right side of the blood pressure was high due to the anatomic location of the right brachial artery. Hypertension survey also stressed the right upper limb blood pressure measurement prevail. In recent years, some people also to brachial artery position for the reason that the left high blood pressure. The above questions and their clinical implications are discussed below. Subjects and Methods There was no choice of measuring left and right upper extremity blood pressure (interval 3 minutes) for medical clinic staff in our hospital. Excluding macrovascular disease and measurement of blood pressure greater than 140 / 90mmHg on both sides
