In recent years, cardiac rhythm disturbances in childhood become to be frequently encountered problem, with the increased postoperative population size. Electrocardiyography (ECG), at rest gives an idea for only short period of cardiac rhythm and lots of this disturbances are overlooked. In this study, 24-hour holter ECG recordings of 490 patients. In this retrospective study, we have revised our patients with dysrhytmia and we want to emphasize the importance of holter ECG in pediatric cardiology. Age range was between 6 days and 28 years and average was 11±5 years. Indications of 24-hour holter ECG were in order: Dysrhythmia found on ECG or cardiac auscultation without symptom (42 %), palpitation (9 %), palpitation and chest pain (10 %), syncope (7 %), SA and AV node dysfunction (6 %), palpitation and dysrhythmia (5 %), control of pacemaker (4 %), control of intracardiac defibrillator (3 %), palpitation and syncope (2 %), and long QT syndrome (2 %). In addition, holter ECG results of 30 patients with asymptomatic isolated false tendon were evaluated. Results of 246 of patients (53.4 %) were found to be normal. In 214 of patients, different spectrum of rhythm disturbances were detected. These findings in order were ventricular dysrhytmia 112 patients (52.3 %), supraventricular dysrhytmia 45 patients (21 %), supraventricular in combination with ventricular dysrhytmia 17 patients (9 %), complete AV block 19 patients (8.8 %), first and second degree AV block 10 patients (4.6 %), WPW syndrome 7 patients (3.2 %), long QT syndrome 4 patients (1.8 %).

24-hour holter ECG is a reliable tool in diagnosis, choice of treatment and follow up of patients with dysrhytmia.
