More Details: Abstract Aims The aim of this study was to investigate the diagnostic and prognostic utility of the QRS‐T angle, an electrocardiogram (ECG) marker quantifying depolarization–repolarization heterogeneity, in patients with suspected acute decompensated heart failure (ADHF). Methods and results We prospectively enrolled unselected patients presenting to the emergency department with symptoms suggestive of ADHF. The QRS‐T angle was automatically derived from a standard 12‐lead ECG recorded at presentation. The primary diagnostic endpoint was a final adjudicated diagnosis of ADHF. The primary prognostic endpoint was all‐cause mortality during 2 years of follow‐up. Among the 1915 patients enrolled, those with higher QRS‐T angles were older, were more commonly male, and had a higher rate of co‐morbidities such as arterial hypertension, coronary artery disease, or chronic kidney disease. ADHF was the final adjudicated diagnosis in 1140 (60%) patients. The QRS‐T angle in patients with ADHF was significantly larger than in patients with non‐cardiac causes of dyspnoea {median 110° [inter‐quartile range (IQR) 46–156°] vs. median 33° [IQR 15–57°], P
