Prognostic impact of morphology and duration of premature ventricular contractions in a population without structural heart disease

open access: yesAnnals of Noninvasive Electrocardiology, 2023
Background Premature ventricular contractions (PVCs) are a common form of arrhythmia associated with an unfavorable prognosis in patients with structural heart disease. It is unclear whether PVCs site of origin and QRS‐width has a prognostic significance
