窦性心动过速一般不需特殊的抗心律失常治疗,因为它是血流动力学的代谢的或肾上腺素能的应激作用于心脏的一种生理信号。当病人出现与生理需要不相称的且来自药物治疗、嗜铬细胞瘤或甲状腺机能亢进的窦性心动过速时,用β肾上腺素能阻滞剂降低窦性心率通常是有效的。本文报告1例 Sinus tachycardia generally does not require special antiarrhythmic therapy because it is a physiological signal that hemodynamic metabolism or adrenergic stress acts on the heart. Reducing sinus heart rate with β-adrenergic blockers is often effective when patients develop sinus tachycardia that is not commensurate with their physiological needs and comes from drug therapy, pheochromocytoma, or hyperthyroidism.
