早期复极(亦叫过早复极)综合征,是由于心脏在复极过程中位相2(平台)心肌缩短所致,确切原因尚不明了,可能和迷走神经张力增高有关,多见于1.0％～6.1％健康男性,这是非器质性心脏病的特征,因此需要和急性心肌梗塞、急性心包炎和变异性心纹痛鉴别,以免造成误诊。1 心电图的表现见图1示意图。 Early repolarization (also known as premature repolarization) syndrome, is due to the heart during repolarization phase 2 (platform) myocardial shortening due to the exact cause is not clear, may be related to increased vagal tone, more common in 1.0% ~ 6.1% of healthy men, this is a non-structural heart disease characteristics, and therefore need and acute myocardial infarction, acute pericarditis and varicose heart disease identification, so as to avoid misdiagnosis. 1 ECG performance shown in Figure 1 schematic.
