SSSy – sick sinus syndrome, AV – atrioventricular, LBBB – left bundle
branch block, RBBB – right bundle branch block, BBB – bundle branch
block, UHF-ECG – ultra-high frequency ECG, * HV – His to ventricle
(RBB potential-ventricle intervals in patients with HV < 35 ms
are included), RWPT – R wave peak time, cSp – conductive system septal
pacing

RVIT, RVOT captures and spontaneous rhythms without bundle branch blocks
