无创性(非侵入性)心脏检查技术近年来发展迅速,不仅广泛用于各种心血管疾病的诊断,而且是评价心功能状态、观察病情、疗效考核和估价预后的极有用的方法。无创性心脏检查包括常规体表心电图(ECG)、动态心电图、超声心动图(M型、二维、三维和多普勒超声心动图等)、心尖搏动图、心阻抗图、颈动脉波、体表希氏束电图、食管心房调搏技术、X线检查、电子计算机断层扫描(CT)、核磁共振(nuclear magnetic resonance,NMR)以 Noninvasive (noninvasive) cardiac examination has developed rapidly in recent years. It is widely used not only in the diagnosis of various cardiovascular diseases but also as a useful method for assessing the status of cardiac function, observing the condition, evaluating the curative effect and assessing the prognosis. Noninvasive cardiac examinations include conventional surface electrocardiogram (ECG), ambulatory electrocardiogram, echocardiography (M type, two dimensional, three dimensional and Doppler echocardiography, etc.), apex cardiogram, cardiac impedance plot, carotid artery wave, Table His bundle, Esophageal atrial pacing technique, X-ray examination, computed tomography (CT), nuclear magnetic resonance (NMR)
