Myocardial contusion is far more common, but its clinical significance is questionable, unless accompanied by ventricular dysfunction or dysrhythmia. The presence of biochemical markers of cardiac injury, specifically troponin, may only be important when combined with echocardiographic findings of right ventricular dysfunction.

Perform an ECG. Myocardial contusion may result in ventricular conduction abnormalities and arrhythmias.ECG abnormalities range from sinus tachycardia, atrial fibrillation, bundle branch block and ventricular extrasystoles to non-specific ST and T wave abnormalities or ST elevation.

At the same time, the status of the neck veins must be noted. A patient who is in shock with flat neck veins is assumed to have hypovolaemic shock until proven otherwise. If the neck veins are distended, the most likely possibilities are: Tension pneumothorax.Pericardial tamponade.Myocardial contusion (cardiogenic shock).Myocardial infarction (cardiogenic shock).Air embolism.

Clinically significant cardiac injury occurs in 5-15% of cases of BCT (5). Most commonly this is myocardial contusion. Rarely, the coronary vasculature may be damaged which can result in MI. One early study found only 10 cases of coronary injury out of 546 cases of BCT (4) with only 77 cases reported in more recent worldwide literature (1). The rarity of this presentation means the understanding of this condition remains limited.
