INTRODUCTION: Increased methadone use in patients with pain has raised concerns that the effect of methadone on the QT interval duration and the potential risk of torsades de pointes (TdP) has been underestimated. Most studies on prolonged QT intervals by methadone are performed in maintenance patien...
The QT interval, which marks the "vulnerable" period of ventricular repolarization, is related to heart rate and can be affected by a broad range of physiopathologic conditions. The interval is considered to be prolonged when, once normalized for heart rate (QTc), it exceeds 0.44 to 0.45 seco...
Electrical systole duration has been studied in two groups of 23 patients (39 M and 7 F) admitted in the coronary care units of two different hospitals for documented acute myocardial infarction (AMI). The mean QT interval duration corrected for heart rate (QTc) was obtained from three ...
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 ...
The aim of this follow-up trial was to describe the association between the length of the QT interval, as a marker of myocardial electrical stability, and the risk of death in insulin-dependent (IDDM) diabetic patients with overt diabetic nephropathy. A consecutive sample of 85 IDDM patients ...
1 There are multiple factors that affect the duration of the QT interval including sex, heart rate and underlying heart rhythm. In clinical practice it is most relevant to correct QT for heart rate; Bazett’s formula (QTc = QT/√RR) is most widely used. Drug interactions can lead to a ...
We found no correlation between body habitus, cardiac dimensions, or metabolic parameters and the rate-corrected QT interval duration in girls with Turner syndrome.Cardiac conduction and repolarization abnormalities seem to affect both young girls and adults with Turner syndrome equally, suggesting that ...
