[Follow-up of the patient with pacemakers: Interrogation and basic programming].

Permanent pacemakers are a frequently used therapeutic modality. Its use has had a great impact on the morbidity and mortality and quality of life of patients with heart rhythm disturbances, with an exponential increase observed in recent decades. The use of this strategy presents different phases, in which follow-up throughout the useful life of the device is a fundamental and determinant pillar of the efficacy and safety of this therapeutic modality. This review seeks to provide a clear and structured update of the fundamental aspects to consider in the follow-up of all patients with pacemakers. The follow-up of the patient with a pacemaker must follow a complete, systematic and periodic protocol, evaluating aspects and parameters related to the patient and the pacemaker, in order to ensure the proper and safe operation of the device adapted to the person.
