There are various kinds of diagnostic examinations in the field of clinical cardiology. In this field, information concerning cardiac structure, dimensions (hypertrophy and dilatation) and cardiac functions are inevitably important. Noninvasive methods are desirable. Except for radiological examinations, electrocardiography and ultrasonic echocardiography are 2 main examinations in cardiology. Holter monitoring is one of the recent topics in clinical electro-cardiology. It is useful for the detection of rest angina or variant angina. Recently "silent myocardial ischemia" has been studied by using this method. This method is also useful for the study of arrhythmia, which is a major cause of sudden death. Quantitative analysis of arrhythmia in the studies of antiarrhythmic drugs can also be done by Holter monitoring. Late potential is also a topic in electro-cardiology. Ultrasonic echocardiography can detect the changes of cardiac structure and function. Doppler echocardiography, developed recently, has made it possible to estimate intracardiac pressure (especially pulmonary arterial pressure) noninvasively. With esophageal echocardiography findings in left atrium, such as thrombus or myxoma in left atrium can be obtained. The most appropriate tool must be selected from the many kinds of diagnostic examinations for efficient clinical diagnosis and therapy.
临床心脏病学领域有各种各样的诊断检查。在该领域，有关心脏结构、尺寸（肥厚与扩张）及心脏功能的信息必然很重要。非侵入性方法是可取的。除放射学检查外，心电图和超声心动图是心脏病学中的两项主要检查。动态心电图监测是临床心电图学的最新热门话题之一。它有助于检测静息型心绞痛或变异型心绞痛。最近已用这种方法对“无症状心肌缺血”展开研究。该方法对心律失常的研究也很有用，心律失常是猝死的主要原因。在抗心律失常药物研究中，也可通过动态心电图监测对心律失常进行定量分析。晚电位也是心电图学的一个话题。超声心动图可检测心脏结构和功能的变化。最近开发的多普勒超声心动图已使无创估计心内压力（尤其是肺动脉压力）成为可能。通过食管超声心动图可获得左心房的相关发现，如左心房血栓或黏液瘤。必须从众多诊断检查中选择最合适的工具，以实现高效的临床诊断和治疗。
