Aims: Intravenous procainamide and amiodarone are drugs of choice for well-tolerated ventricular tachycardia. However, the choice between them, even according to Guidelines, is unclear. We performed a multicentre randomized open-labelled study to determine the safety and efficacy of intravenous procainamide and amiodarone for the acute treatment of tolerated wide QRS complex (probably ventricular) tachycardia. Methods and results: Patients were randomly assigned to receive intravenous procainamide (10 mg/kg/20 min) or amiodarone (5 mg/kg/20 min)...

OBJECTIVES: To evaluate whether patients who experience cardiac arrest in hospital receive epinephrine (adrenaline) within the two minutes after the first defibrillation (contrary to American Heart Association guidelines) and to evaluate the association between early administration of epinephrine and outcomes in this population. DESIGN: Prospective observational cohort study. SETTING: Analysis of data from the Get With The Guidelines-Resuscitation registry, which includes data from more than 300 hospitals in the United States...

OBJECTIVE: Biomarkers are a critical component in the investigation of patients with potential ischaemic heart disease. The proposed benefits of a high-sensitivity troponin (hs-Tn) assay include earlier diagnosis of myocardial infarction. However, the decreased specificity may adversely affect clinical practice. The present study aims to investigate the impact that the introduction of a hs-Tn assay had on patients presenting to the ED. METHODS: A pre- and post-interventional analysis was performed on all patients presenting to the Royal Melbourne Hospital ED, and had a troponin, in the 12 months before and after the introduction of the hs-Tn assay...

We present a rare case of a young patient with chest pain whose ascending thoracic aortic aneurysm (TAA) was detected by point-of-care ultrasound (POCUS) leading to a successful surgical repair. POCUS identified a moderate pericardial effusion and an associated severely dilated ascending aorta. In this context, it is important to rule out aortic rupture and aortic dissection. We also discuss the epidemiology, complications, and management of TAAs as well as the role of cardiac POCUS in the diagnosis of thoracic aneurysmal disease...

ST-segment elevation myocardial infarction (STEMI) is defined as pathologic ST-segment elevation occurring in at least 2 anatomically contiguous leads in a patient with a clinical presentation consistent with acute myocardial infarction (AMI); these findings can suggest the need for urgent revascularization. Unfortunately, the electrocardiogram (ECG) may be nondiagnostic in a large portion of patients who initially present with AMI; furthermore, it is now recognized that ECG patterns that do not meet the traditional diagnostic criteria for STEMI may represent significant AMI--these patterns are generally referred to as the STEMI equivalent patterns in that they are caused by occlusion of an epicardial coronary artery, place significant portions of the left ventricle in jeopardy, and can result in a poor outcome if not recognized and treated appropriately...
