Thromboelastography (TEG) has been recommended to characterize post-traumatic coagulopathy, yet no study has evaluated the impact of pre-injury anticoagulation (AC) on TEG variables. We hypothesized patients on pre-injury AC have a greater incidence of coagulopathy on TEG compared to those without AC. ⋯ TEG has limited clinical utility to evaluate the presence of pre-injury AC. Traditional markers of drug induced coagulopathy should guide reversal decisions.

Brugada syndrome (BrS) is a genetic heart disorder due to alteration of the ion channels function that causes an impaired in the cardiac conduction system. It is characterized by an abnormal electrocardiogram pattern and may be complicated by malignant ventricular arrhythmias. Pericarditis is an inflammation of the pericardium and 90% of isolated cases of acute pericarditis are idiopathic or viral. Acute pericarditis may appears with chest pain, fever, pericardial friction rub, and cardiac tamponade. Moreover, widespread ST segment changes occur due to involvement of the underlying epicardium. ⋯ Our case report shows that the pericarditis may mimic BrS. Moreover, it is important to underline that a Brugada ECG pattern should only be considered as a sign of electrical heart disease but detailed diagnostic tests are anyway needed.

Case Reports
Not all ST-segment elevations are myocardial infarction: Hyperkalemia and Brugada phenocopy.
Several clinical conditions other than Brugada syndrome (BrS) can mimic acute ST-segment elevation myocardial infarction and Brugada phenocopies are a part of those conditions that can mimic either true BrS or acute myocardial infarction. Our manuscript shows an interesting and didactic case report of type-1 Class A Brugada phenocopy (BrP) induced by hyperkalemia and allow us to teach the systematic approach to the proper diagnosis of BrP. A prompt recognition of this clinical and electrocardiographic entity may expedite the initiation of appropriate treatments as illustrated in this case report.
