Суточная оценка нарушений ритма и проводимости показала, что нарушение ритма сердца по типу частой наджелудочковой экстрасистолии (до 17 560/сут) и частой желудочковой экстрасистолии (до 22 450/сут) встречалось преимущественно у спортсменов, тренирующих выносливость (аэробные нагрузки), тогда как у спортсменов, тренирующих скоростно-силовые качества (динамические нагрузки), чаще регистрировалось нарушение проводимости по типу АВ блокады 2-й степени, Мобитц 1 (с максимальной продолжительностью пауз до 3 сек). У спортсменов с бругадоподобными изменениями при ХМ – ЭКГ и ЭхоКГ изменений не выявлено, однако они находятся под пристальным контролем.</p></abstract><trans-abstract xml:lang="en"><p>The article presents research data of 12-lead electrocardiography at rest (Rest ECG) and Holter ECG monitoring of athletes. Daily assessment of cardiac rhythm and conduction disturbances showed that the cardiac rhythm disorders by type of frequent supraventricular arrhythmia (up to 17 560/day) and frequent ventricular arrythmia (up to 22 450/day most frequently encountered in endurance-athletes (aerobic exercises), whereas the athletes training speed-strength (dynamic loads) had conduction disturbances by type of the second-degree AV block, Mobitz Type 1 (with a maximum duration of pauses up to 3 seconds). However, changes in Holter ECG and EchoCG have not been revealed in athletes with Brugada-like changes, but they are still under close control.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спортивное сердце</kwd><kwd>нарушение ритма сердца</kwd><kwd>холтеровское мониторирование ЭКГ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>athlete’s heart</kwd><kwd>heart rhythm disorder</kwd><kwd>Holter ECG</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Деряпа Н.Р.
