Acute local myocardial ischaemia is associated with a decrease in baroreflex sensitivity while electrical instability (vulnerability) of ventricles increases. Co-administration of a benzodiazepine and a potent analgesic (analgosedation) has been found to raise both baroreflex sensitivity and ventricular fibrillation threshold. Pharmacological modulation of neurovegetative ionization of the heart in the early phase of ischaemia is a promising method for preventing sudden coronary death.
急性局部心肌缺血与压力反射敏感性降低相关,而心室的电不稳定性(易损性)增加。已发现同时给予苯二氮䓬类药物和强效镇痛药(镇痛镇静)可提高压力反射敏感性和心室颤动阈值。在缺血早期对心脏自主神经离子化进行药理学调节是预防心源性猝死的一种有前景的方法。
