Moreover it returns the QT corrected interval expressed in both seconds and milliseconds.
Normal paediatric ECG • LITFL • ECG Library Diagnosis
WebKey points. Supraventricular tachycardia (SVT) is common in infancy and childhood. Most SVT in children is due to a re-entrant mechanism and usually occurs in otherwise normally well children. Greater than a third of new onset SVT occurs in the first few weeks of life, commonly presenting after many hours with signs of heart failure. WebMean QTc interval for all patients in DKA was 454 ± 32 msec. Mean QTc in the mild group was 441 ± 22 msec, moderate group 460 ± 36 msec, and severe group 461 ± 34 msec. There was a significant difference in QTc interval across DKA severity groups (P = .05). There was a significant association between higher anion gaps and greater QTc ... coffee 1450
