The ECG interpretative statement "Prol onged QT" means different things to different people. It can be taken as a purely descriptive statement referring to the QT interval beyond a certain threshold. Alternatively, it could be taken to refer to a disease state (eg, congenital long QT syndrome...
Objective To evaluate the effect of diabetic ketoacidosis (DKA) on the QT interval corrected for heart rate (QTc) in children. Ketosis occurs in several conditions, including DKA and alcoholic ketoacidosis, and during use of very low-carbohydrate diets. Prolongation of the QTc has been described ...
Psychotropic drugs have been associated with sudden deaths and the lengthening of corrected-QT interval (QTc) on the electrocardiogram which may be a precursor of life-threatening arrhythmias as reported with some of these drugs. The objectives of this study were to measure the frequency of QTc le...

We attempted to evaluate whether subjects who exhibit prolonged corrected QT (QTc) interval (≥440 ms in men and ≥460 ms in women) on ECG, with and without ECG-diagnosed left ventricular hypertrophy (ECG-LVH; Cornell product, ≥244 mV×ms), are at increased risk of stroke. Among the 10...

Subsequent echocardiogram and 24 h ECG were normal. Following surgical intervention for the fracture, and input from the multi-disciplinary team, the patient was transferred to a community rehabilitation facility. Discussion The QT interval is the measurement between the start of the QRS complex and ...
The ECG is abnormal in most patients with arrhythmogenic right ventricular dysplasia (ARVD). Right ventricular parietal block, reduced QRS amplitude, epsilon wave, T wave inversion in V1-3 and ventricular tachycardia in the morphology of left bundle branch block are the characteristic changes that ...
