Criteria for diagnosing hypertrophy of the right and left ventricles were developed. heart in children 3-7 and 8-15 years old Comparative analysis of the results indicates a higher sensitivity of the Frank system compared with 12 conventional leads in identifying left ventricular hypertrophy in children.</p>ventricular hypertrophyECGcorrected orthogonal leadsгипертрофия желудочковЭКГкорригированные ортогональные отведения
