左心室假肌腱的解剖发生率已经确定了100心脏从连续解剖的病人谁有各种各样的心脏状况。本组病例中，34例发现异常带。一项回顾性二维（2D）超声心动图研究仅能在18%的解剖证据中识别出假肌腱，这表明即使有适当的投影，2mm也是二维超声心动图分辨率的极限。最后，组织学检查显示假肌腱包含传导组织，因此假定是His束的腔内辐射。最后的考虑引入了新的物理和电生理含义。
The anatomic incidence of left ventricular false tendons has been determined in 100 hearts obtained from consecutive autopsies on patients who had a wide variety of cardiac conditions. In this series, an anomalous band was found in 34 cases. A retrospective two-dimensional (2D) echocardiographic study was able to identify false tendons in only 18 percent of cases with anatomic evidence of them, indicating 2 mm as the limit of resolution of 2D echocardiography even with appropriate projections. Finally, the histologic examination has shown false tendons to contain conduction tissue and thus it is assumed to be intracavitary radiations of the bundle of His. This last consideration introduces new physical and electrophysiologic implications.
