In an analysis of 44896 ECGs representing all adult non鈥搗entricular-paced ECGs in a major hospital ECG database over the course of 1 calendar year, the computerized interpretation program stated "Prolonged QT" on 9.8% of the ECGs. However, 36.2% of all ECGs had a QTc more than 460 ...

In acquired long QT syndrome with no prior suggestive feature, it is not impossible to miss the prolonged QT-interval on the ECG tracing. We share our experience so that the clinicians, especially the junior doctors, will be more alert on checking the QT-interval even in asymptomatic patients...
In the event of an overdose, QT prolongation can occur and ECG monitoring should take place for at least 2 days after ingestion in order to prevent life-threatening arrhythmias such as torsades de pointes (tdp). Other factors and drugs that could contribute to prolongation of the QT interval ...
In conclusion, (1) a significant number of patients (24% to 32%) with dilated or hypertrophic cardiomyopathy may have a long QTc interval on the surface ECG, and (2) ventricular hypertrophy/dilation may be additional rare causes of acquired prolongation of the QT interval. 展开 ...
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...
Multivariable analysis was performed using the composite outcome as the dependent variable and APACHE II score and prolonged QT as the independent variables.RESULTS: We identified 112 patients with ECG at the time of ICU admission or MV. A prolonged QTc interval was present in 17 (15.2%) of ...
On admission the patient’s electrocardiogram (ECG) demonstrated normal sinus rhythm with a prolonged corrected QT interval (QTc) of 638 ms (the upper limit of normal for females is 460 ms).1 Blood tests, including electrolytes, were all within normal limits and there was no postural blood pr...
