title: [Usefulness of ambulatory ECG in the follow-up of patients with pacemakers].
abstract: In order to evaluate the diagnostic efficacy of Holter monitoring in the follow-up of pacemaker patients, the recordings of 122 patients were reviewed. Indications for monitoring were: evaluation of pacemaker function in 23.6% of the cases; sporadic appearance of arrhythmias in 26.7%; total or partial unconsciousness in 9.7%; a variety of symptoms such as palpitation (12.7), dizzy-spells (9.7%) and irregular pulse (4.2%). Prolonged monitoring of cardiac activity allowed us to exclude pacemaker malfunction in 87.5% of cases of syncope and 88.6% of cases of palpitation, dizzy-spells and irregular pulse; while it disclosed defects of electrostimulation in 11.4% of cases in loss of consciousness in 12.5% of patients with various symptoms and none in cases of arrhythmias. It allowed us to evaluate the therapeutic efficacy of used drugs in 18.2% of cases. Given the variety of clinical and instrumental problems of pacemaker patients, Holter monitoring proved to be a very essential diagnostic means in the follow-up of such patients.
