这关键区别between systolic and diastolic pressure is thatsystolic pressure is the pressure building on the arterial wall during the phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into动脉舒张压是心肌放松并允许腔室充满血液时,舒张压是动脉壁上的压力。
Pressure is the word commonly used to refer to arterial blood pressure. The heart is the organ that acts as a pump to carry out the blood circulation throughout the body. When the heart pumps, the blood will enter theaorta用力量。当加压血进入主动脉时,它会在其墙壁上施加压力,主动脉具有伸展和扩展的弹性能力。之后,心脏将再次放松,主动脉的血液供应停止,主动脉开头的瓣膜关闭。目前,主动脉从扩张位置恢复正常位置。同样,这种后退将对血液施加压力。

什么是收缩压?
Systolic pressure is one of the two values described in blood pressure. It is the pressure blood exerts against the artery walls when the heart beats. Heart muscles contract and the heart pumps blood to the aorta with a force. Then the blood exerts a pressure on the artery wall.
通常,健康人的收缩压应低于120毫米Hg。在沉重的工作中,您感到恐惧等情况下,收缩压可能会提高到更高的水平。但是,其余的水平恢复正常。低收缩压会导致一种称为收缩性低血压的疾病,该疾病会产生头晕,头晕,晕厥或器官衰竭。低收缩压背后的原因可能是血容量太低,血管无力或血液扩张。
什么是舒张压?
舒张压是血压中指示的第二个值。当心脏休息或放松时,血液对动脉壁施加的压力。舒张压发生在心跳之间。在这一点上,心脏无法积极地将血液泵入动脉。这是心肌收缩的心室松弛期和准备期。
此外,健康个体的舒张压为80 mm Hg或以下。
What are the Similarities Between Systolic and Diastolic Pressure?
- Systolic and diastolic blood pressures represent the pressures within the blood vessels during different parts of the cardiac cycle.
- 两种压力因个人的活动而异。
- 此外,女性的收缩压和舒张压可能较小。
- 此外,儿童的收缩压和舒张压也较小。但是,这取决于他们的年龄和活动。
- 准确地衡量这两个值对于诊断和管理很重要hypertension。
What is the Difference Between Systolic and Diastolic Pressure?
收缩压和舒张压是两个表示个体血压的测量。收缩压是当心脏肌肉收缩并心脏将血液泵入动脉时,血液在动脉壁上延伸的压力。相反,舒张压是当心脏在心跳之间放松时,血液在动脉壁上延伸的压力。因此,这是收缩压和舒张压之间的关键区别。
比较这两个值时,收缩压更为重要,因为它会增加心血管疾病的风险。健康的个体具有120 mm HG收缩压和80 mm Hg舒张压。因此,我们也可以将其视为收缩压和舒张压之间的差异。
摘要 - 收缩压与舒张压
Blood pressure is indicated in two values: systolic pressure and diastolic pressure. The systolic pressure is the pressure on the arterial wall during the heart muscle contraction. Diastolic pressure is the pressure when the heart is relaxing. In a healthy individual, the normal systolic pressure is 120 mm Hg while the diastolic pressure is 80 mm Hg. Elevated systolic and diastolic pressure values indicate the risk of cardiac diseases and hypertension. Thus, this summarizes the difference between systolic and diastolic pressure.
