QRS Morphology in Lead V1 for the Rapid Localization of Idiopathic Ventricular Arrhythmias Originating from The Left Ventricular Papillary Muscles: A Novel Electrocardiographic Criterion

12-lead electrocardiogram (ECG) criteria have been developed to identify idiopathic ventricular arrhythmias (VAs) from the left ventricular (LV) papillary muscles (PAPs), but accurate localization remains a challenge.
