Left Ventricular Dysfunction
Major morbidity and mortality due to myocardial contusion occurred in 17 per cent of the (7/42) patients; of these, three had biventricular dysfunction, one had left ventricular dysfunction, and two had a low cardiac index. [ncbi.nlm.nih.gov]
Such injuries usually manifest as a combination of left ventricular dysfunction and cardiogenic shock. Blunt pericardial rupture is rare but may be the most severe form of blunt cardiac injury. [aast.org]

Impulsivity
Cardiac contusion may be frequently found in patients with blunt chest trauma, and it presents clinically as a spectrum of injuries of varying severity, including transient disorders of impulse formation and propagation. [ncbi.nlm.nih.gov]
[…] myocardial contusion may have the following effects: bleeding into the membrane that surrounds the heart, which can cause cardiac tamponade bleeding within the heart muscle conduction problems, or an abnormality in the transmission of the electrical impulses [medicineonline.com]
Workup
Of the 644 admissions to monitored beds, 95 had workups for suspected contusion. Heart failure not obvious on admission did not occur and there were only four arrhythmias that required treatment. [ncbi.nlm.nih.gov]
Radiologic workup revealed a bilateral pleural effusion, a fracture of the right collarbone, a hepatic contusion, a right adrenal hematoma and a fracture of the left iliac wing. [panafrican-med-journal.com]
The authors concluded that a cTnI greater than 1.05 µg/L necessitated further workup. Neither CK total or CK-MB were helpful in predicting BCI. [east.org]
The initial workup revealed elevated cardiac troponin T of 0.576 μg/L (normal range, 0.00 to 0.03 μg/L) and creatine kinase-MB levels of 25.4 U/L (normal range, 0 to 25 U/L); the markers of inflammation proved to be negative (C-reactive protein level, [circ.ahajournals.org]
