一定程度的行为应激可通过神经——内分泌系统等诱发冠脉缺血,血流变学变化和心电紊乱,易促发危重型心律失常。通过较多的资料表明,由于个体之间的交感激惹阈存在一定的差异。所以,行为应激对个体的损害亦不同。但造成危害的机制,除上面所述之外,可能还有一些不知因素参与,尚需进一步深入研究(如建立生物应激模型等)。 A certain degree of behavioral stress induces coronary ischemia, changes in hemorheology and ECG disturbance through the neuroendocrine system, and it is easy to induce critical arrhythmia. More information shows that due to the interaction between individuals sympathetic stimulation there are some differences. Therefore, behavioral stress is also different damage to individuals. However, besides the above, there may be some unknown factors involved in the mechanism causing harm, which requires further study (such as the establishment of biological stress models).
