Carbon monoxide (CO) poisoning frequently affects repolarization, resulting in abnormal electrocardiography findings. The goal of this study was to examine the effect of CO poisoning on the novel transmyocardial repolarization parameters T peak-T end (Tp-e), Tp-e dispersion, and Tp-e/QT and the relationship of these parameters to myocardial injury (MI). ⋯ Transmyocardial repolarization parameters indicative of arrhythmia were prolonged in patients with CO poisoning. T peak-T end was associated with MI.

A 53-year-old woman was hospitalized after out-of-hospital cardiac arrest due to ventricular fibrillation. Initial electrocardioagram showed sinus rhythm of 117 beats per minute, 452 ms QTc interval, ST-segment depression up to 1 mm in V(2)-V(6), and ST-elevation in lead aVR. ⋯ Laboratory test results showed hypocalcaemia. After rewarming and ion correction QT abnormalities resolved.

Behçet's disease is a multisystemic, potentially life-threatening condition with vascular involvement and thrombotic tendency. The disease course is characterized by exacerbations and remissions. Lower extremity vein thrombosis is the most frequent manifestation of vascular involvement, followed by vena cava thrombosis, pulmonary artery aneurysms, peripheral artery aneurysms, dural sinus thrombosis and abdominal aorta aneurysms. The case in this report was considered worth reporting due to vena cava thrombosis extending from brachiocephalic to jugular vein, accompanying thrombosis of the contralateral brachiocephalic vein and jugular veins as well as simultaneous dural sinus thrombosis, and also benefit from thrombolytic therapy.

Comparative Study
Differences of postresuscitation myocardial dysfunction in ventricular fibrillation versus asphyxiation.
This study aims to characterize postresuscitation myocardial dysfunction in 2 porcine models of cardiac arrest (CA): ventricular fibrillation cardiac arrest (VFCA) and asphyxiation cardiac arrest (ACA). ⋯ Compared with VFCA, ACA causes more severe cardiac dysfunction associated with less successful resuscitation and shorter survival time.

Observational Study
Clinical features of patients inappropriately undiagnosed of pulmonary embolism.
The objective of this study was to identify clinical factors associated with delayed diagnosis of acute pulmonary embolism (PE) in the emergency department (ED). ⋯ Delay in diagnosis of acute PE is frequent despite current diagnostic strategies. Patients are sent home or admitted to hospital with a wrong diagnosis depending on clinical presentation or coexisting medical conditions.
