[Electrocardiography with the use of the orthoclinostatic test in the diagnosis of extrasystolic arrhythmia in childhood]. / Elektrokardiografiia s primeneniem ortoklinostaticheskoi proby v diagnostike ékstrasistolicheskoi aritmii v detskom

The differential-diagnostic importance of some ECG criteria and results of orthoclinostatic test in distinguishing functional form organic extrasystolic arrhythmias in childhood is appraised. Among the electrocardiographic indices the coupling interval is of great importance in differential diagnosis. Left-ventricular extrasystole is mostly encountered in rhythm disorders of functional origin. The data of the orthoclinostatic test are highly reliable in distinguishing functional disorders of rhythm from organic disorders.
