Brief summary
Temporary cardiac pacing with active-fixation leads (TPAFL) using a reusable permanent pacemaker generator has been shown to be safer than lead systems without fixation. However, TPAFL requires the off-label (non-certificated) use of Pacemaker leads and generators. It is designed a fastening system to ensure the safety and efficacy of the procedure: the KronoSafe System®. The aim of this study is to demonstrate the safety and effectiveness of the KronoSafe System® for temporary pacing in a series of patients receiving TPAFL.
Interventions
All patients included in the study will have a temporary pacemaker with active fixation leads, held by the KronoSafe® fixation system.

Study design
Intervention model description
The study will be carried out in an Arrhythmia Unit or Intensive Care Unit. Patients who need urgent temporary cardiac pacing due to bradycardia, or elective pacing to prevent heart rhythm disturbances during high-risk arrhythmia interventions, such as transcatheter aortic valve implantation (TAVR), alcoholic septal ablations, etc., will be included. After the temporary pacemaker implantation with active fixation electrode in a correct way, the KronoSafe® external pacemaker fixation system will be placed. The correct functioning of the system (R wave detection, lead impedance and right ventricle threshold) will be checked at 24 hours and every other day until the end of cardiac stimulation. During temporary pacing, associated complications are going to be recorded: lead displacement, capture or sensing failure, generator or lead detachment, and cardiac perforation.
Eligibility
Inclusion criteria
* Patient older than 18 years. * Need for temporary cardiac stimulation * Temporary active fixation pacemaker implantation through left or right jugular access. * Signature of informed consent * Correct functioning of the electrode after the implantation: sensing of the R wave above 5 millivolts. Ventricular pacing threshold below 1 volt. Electrode impedance between 400-1200 Ohm. * Pacemaker programming with stimulation output at 5 volts intensity and 1 millisecond pulse duration. * Placement of the KronoSafe® fastening system after electrode implantation.
Exclusion criteria
* Complication during the procedure: pneumothorax, hematoma at the puncture site, cardiac perforation, accidental arterial puncture or other that, in the investigator's opinion, poses an added risk of pacemaker dysfunction. * Need to transfer the patient to another center with loss of follow-up. * Absence of surveillance through continuous electrocardiographic monitoring with detection of arrhythmic events.
