The Study Of Prolonged Qtc Interval As A Predictor Of Outcome In Patients Admitted With Medical Emergencies

Abstract

To study the QTc interval in patients admitted as medical emergencies and to predict in-hospital outcomes of the patients MATERIAL and METHODS: Prospective observational study carried out in 312 patients admitted in our hospital with Acute medical emergency. Clinical, echocardiographic and laboratory profile and in-hospital outcome of patients with medical emergencies were assessed as a part of work up. QTc interval was calculated by using Bazzets formula with in 24hrs of admission by using standerd 12 lead ECG . Patients with QTc ≥0.44 sec in male and QTc ≥0.46 sec in females were taken as the cutoff value for prolonged QTc interval and values were compared with outcome and duration of stay in hospital . The patients during hospital stay and were observed for out come like duration of stay ,development of major complications or worsening of symptoms ,and death were assessed in relation to the QTc interval
