摘要

心脏是一个泵，每分钟跳动72次，相当于1.2赫兹，每次跳动持续约0.830毫秒(毫秒)，以促进血液循环，运输和分配营养和氧气，维持液体和体温的平衡，并从身体所有细胞中清除二氧化碳和其他代谢副产物。在一年的时间里，不考虑心率通常会上升的压力和情绪时刻，心脏跳动约为38843300次。因此，一个每天24小时工作，泵出大约2亿升血液(超过70年的寿命)来维持我们生命的系统的重要性这项工作旨在综合心脏周期的生理学，并指出心脏周期失败后的主要影响。

The heart cycle: review

The heart is a pump that performs 72 beats per minute, equivalent to 1.2 Hertz, which each beat lasts around 0.830 ms (milliseconds) to boost the blood circulation that transports and distributes nutrients and oxygen, maintains the balance of fluids and body temperature as well as removes carbon dioxide and other metabolic byproducts from all cells of the body. Over a year, the heart beats around 38,843,300 times without taking into account the moments of stress and emotion in which the heart rate normally rises. Hence the importance of a system that works 24 hours a day, pumping about 200 million liters of blood (over a life of 70 years) to keep us alive.1 This work aims to synthesize the physiology of the cardiac cycle as well as to point out the main affections after a failure of this cycle.

期刊介绍： For many diseases, women’s physiology and life-cycle hormonal changes demand important consideration when determining healthcare management options. Age- and gender-related factors can directly affect treatment outcomes, and differences between the clinical management of, say, an adolescent female and that in a pre- or postmenopausal patient may be either subtle or profound. At the same time, there are certain conditions that are far more prevalent in women than men, and these may require special attention. Furthermore, in an increasingly aged population in which women demonstrate a greater life-expectancy.
