Mapping analysis of cardiokymography is helpful in clarifying the relationship between vibratory pattern and recording sites, but needs a highly stable recording technique. We have therefore studied the stability of recording cardiokymograms, and present here a new method for creating stable maps which enables diagnosis of chest-wall vibration abnormalities. Cardiokymograms were recorded on 16 points of the chest wall located at regular intervals horizontally and vertically. The time interval between a R-wave peak of the electrocardiograms and an E-point of the cardiokymograms were measured for all the 16 records. Isochronal maps in 23 healthy subjects were classified into four types. The map of a patient with myocardial infarction was quite different from any one of the four normal patterns and seemed to show a paradoxical movement of the chest wall.
心动周期图的映射分析有助于阐明振动模式与记录部位之间的关系，但需要高度稳定的记录技术。因此，我们研究了心动周期图记录的稳定性，并在此提出一种创建稳定图谱的新方法，该方法能够诊断胸壁振动异常。在胸壁上以水平和垂直方向等间隔定位的16个点记录心动周期图。测量所有16份记录的心电图R波峰值与心动周期图E点之间的时间间隔。将23名健康受试者的等时图谱分为四种类型。一名心肌梗死患者的图谱与四种正常模式中的任何一种都有很大不同，似乎显示出胸壁的反常运动。
