蛛网膜下腔出血(SAH)可能伴有心脏的异常,包括心律失常和其他心电图(ECG)变化。中风急性期ECG 的典型变化包括T 波倒置、ST 抬高或下降、QT 间期延长和出现U 波。但是对于ECG 改变的机制仍然不清。有人曾提出心律失常、心肌坏死和ECG异常可能是由于交感系统活性异常的增强所引起。外周交感系统活性的指征——血浆去甲肾上腺素(NE)浓度升高可能与脑血管病时ECG 变化有关。虽然,有人使用了β-肾上腺素阻滞剂,但是,没有临床报告能证实SAH 时NE 升高引起了ECG 的变化。
Subarachnoid hemorrhage (SAH) may be associated with heart abnormalities, including arrhythmias and other ECG changes. Typical changes in acute ECG of stroke include T wave inversion, ST elevation or fall, prolongation of QT interval, and U wave appearance. However, the mechanism of ECG changes remains unclear. It has been proposed arrhythmia, myocardial necrosis and ECG abnormalities may be due to abnormal sympathetic system activity caused by. Indications of Peripheral Sympathetic System Activity - Elevated plasma norepinephrine (NE) levels may be related to ECG changes during cerebrovascular disease. Although beta-adrenergic blockers were used, no clinical report confirms that elevation of NE at SAH causes ECG changes.
