Patients	PM indication	Temporary pacing	Location of deployment	Number of deployments	R-wave amplitude (mV)	Impedance (Ω)	Pacing threshold (V)	Skin to skin implantation time (min)	Time from the TLE to re-implant (days)	Time from the TLE to discharge (days)
AF: atrial fibrillation; CAVB: complete atrioventricular block; PM: pacemaker; SSS: sick sinus syndrome; TLE: transvenous lead extraction.
