早在1861年Chauvean和Marey就首次成功地记录了心尖搏动图(Apexcardiogram,ACG)。但此后这种方法多年未被重视。直到本世纪60年代初期,Dimond和Benchimol令人信服地证实了胸壁搏动与从心内记录的图形的关系,指出心尖搏动图能准确地反映心动周期的收缩和舒张活动,从而又重新唤起了人们对ACG的兴趣。此后许多研究者证实和扩充了他们的研究。目前,ACG已成为确定心室收缩开始,二尖瓣开放,第三心音和第四心音的较准确 As early as 1861, Chauvean and Marey successfully recorded the Apexcardiogram (ACG) for the first time. However, this method has not been taken seriously for years. It was not until the early 1960s that Dimond and Benchimol convincingly confirmed the relationship between chest wall pulsation and the pattern recorded from the heart and pointed out that the apical pulsation diagram accurately reflects the systolic and diastolic activities of the cardiac cycle, Interest in ACG. Since then many researchers have confirmed and expanded their research. At present, ACG has become more accurate in determining the onset of ventricular contractions, mitral valve opening, third heart sounds and fourth heart sounds
