“…Nonetheless, arrhythmias are relatively nonspecific and non-sensitive for the diagnosis of MC which might be affected by several possible etiologies including high catecholamine state, hypoxia, hypokalemia, hypovolemia or even pre-existing heart disease or head injuries. Although various abnormalities of electrocardiography have been reported in patients with MC including ST-segment elevation, T-wave change, bundle branch block, prolonged QT intervals etc., atrial fibrillation/flutter and premature ventricular contractions are more specific for MC [17][18][19]. In the present study, concomitant serious, even fatal ventricular arrhythmias were recorded as soon as the canine precordial region was impacted.…”

We sought to investigate the role of two-dimensional stress echocardiography in the early assessment of myocardial contusion. For this purpose, 12 dogs, weighing 11.36 ± 1.50 kg, were selected and the myocardial contusion was experimentally induced. Two-dimensional dobutamine stress echocardiography (DSE) was used to detect abnormal myocardial motions segments at time phases of baseline and 0.5, 2, 4, and 8 h post-wounding. Finally, the above results were compared with pathological findings. The data show that after the dogs were induced to have severe myocardial contusion, 122 segments were found with abnormal myocardial wall motions at 0.5 h post-wounding, 133 segments at 2 h post-wounding, and 142 segments, each, at 4 h and 8 h post-wounding. The wall motion score (WMS) and wall motion score index (WMSI) increased (P < 0.001) as compared with the pre-impaction values. Considering the left ventricular axis view as the standard section, in the 60 segments examined by echocardiography, 54 segments were found to have wall motion abnormalities. Comparing with the results of pathological TTC staining, the sensitivity and specificity were found to be 100 and 66.6%, respectively. It was, therefore, concluded that two-dimensional DSE was a valuable technique in the early diagnosis of myocardial contusion due to its better sensitivity and specificity.
