Origin distributions for PVC circadian patterns. Origin distributions for F-PVC (a), S-PVC (b), and I-PVC (c), respectively. ASV, aortic sinus of Valsalva; GCV, great cardiac vein; LAF, left anterior fascicle; LAPM, left anterior papillary muscle; LBB, left bundle branch; LPF, left posterior fascicle; LPPM, left posterior papillary muscle; LV, left ventricle; LVOT, left ventricular outflow tract; PSC, pulmonary sinus cusp; PVC, premature ventricular complexes; RV, right ventricle; RVOT, right ventricular outflow tract.
