Detection of cardiac disturbances following thoracic trauma with high-frequency analysis of the electrocardiogram

J Trauma. 1977 Jun;17(6):419-24. doi: 10.1097/00005373-197706000-00002.


High-frequency electrocardiograms (HF-ECG) were recorded from rabbits before and after delivery of blunt, nonpenetrating thoracic trauma. The conventional electrocardiographic record showed transient changes following the blow; the HF-ECG showed distinct notching and slurring in the QRS complex in most cases, which persisted throughout the course of the experiment. At autopsy, a contusive lesion of the right ventricle was always found.
