METHODS
A 35-year-old patient presented with a non-penetrating chest trauma due to an automobile accident. Examinations showed a trauma of the left shoulder (reversed Hill-Sachs lesion). After diagnostic procedures, he underwent surgery four weeks later. During the hospital stay, the patient developed angina pectoris, dizziness and syncopes.
METHODS
When the patient was transferred to our institution a 12-leads electrocardiogram and blood analysis were unremarkable. Cardiac catheterization revealed a relaxation disorder of the left ventricular anterior wall with normal coronaries. The Holter-ECG detected with occasional attacks of dizziness and recurrent syncopes concurrent with intermittent episodes of high-degree atrioventricular block and supraventricular tachycardias. This led to the diagnosis of myocardial contusion with long term symptomatic arrhythmias.
METHODS
Since syncopes and arrhythmias persisted over several weeks following myocardial contusion a combined therapy with a dual chamber pacemaker and beta-blocker was initiated.
CONCLUSIONS
ECG monitoring after blunt chest trauma in the early period and after several days is mandatory to screen and prevent potentially life threatening posttraumatic arrhythmias.
