The article is devoted to the study of location of ventricular arrhythmia focuses in patients with coronary heart disease with a post-infarction cardiosclerosis. The technique of a noninvasive three-dimensional heart mapping with Amikard system was used.
12 patients with coronary heart disease and post-infarction cardiosclerosis were surveyed. In all patients the politopy ventricular extrasystolia was registered. The location of the extrasystolia focuses in the scar zone is revealed in 66,7% of cases, out of scar zone — in 33,3% of cases. The epicardial location is revealed in 5 patients (41,7%) and in all patients the focuses localization coincided with a scar zone of a myocardium. The endocardial location of the focuses coincided with the scar zone in 3 patients, in 4 patients the ventricular extrasystolia focuses were localized out of the scar zone only. Thus, the scar zone was ventricular extrasystolia source in 8 (66,7%) patients, in 33,3% of cases the only out of a scar zone location of the focuses is revealed.
Conclusions:
- Noninvasive three-dimensional mapping of heart with Amikard system in patients with ischemic heart disease with post-infarction cardiosclerosis allows to define localization of the ventricular extrasystolia focuses both in the field of a scar zone and in an ischemic myocardium.
- Epicardial localization of the focuses is characteristic for a scare zone, endocardial — both for an ischemic myocardium, and for a scar zone. (Проверено, исправлено, но этого нет в русском тесте – Прим.переводчика)
