METHOD OF EARLY DIAGNOSTICS OF LATENT ELONGATION OF QT INTERVAL IN PATIENTS WITH MINOR HEART ANOMALIES Russian patent published in 2013 - IPC A61B5/402 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely to cardiology. Displastic syndromes and phenotypes are determined in patients with minor heart anomalies. Medication Atarax is administered in case of myxomatous mitral valve prolapsed MVP, Marfan-like phenotype, syndrome of joint hypermobility and normal QT. Holter ECG monitoring is carried out. If QT interval increases by more than 450 ms on ECG of rest or in Holter ECG monitoring on the second-third day of intake, with duration not less than 0.7% of day monitoring time, latent elongated QT interval is diagnosed. If QT remains lower than 450 ms during entire time of Holter ECG monitoring, norm, absence of latent QT elongation, is diagnosed.

EFFECT: method makes it possible to make diagnostics of QT changes more specific as well as to avoid complications associated with diagnostic intake of adrenalin.
