What conditions or situations cause prolonged QT intervals in the electrocardiogram besides the use of antidepressants? If there is a need for an antiarrhythmic in a patient on an antidepressant, which antiarrhythmics are less likely to cause further prolongation of the QT interval?. ...
We selected for review registries and case series examining clinical outcomes of patients with prolonged QT interval and the effect of different methods of measurement of the QT interval on patient outcomes. Ten studies were identified by the search, of which 6 were included in the analysis.4-9...
(R–R cycle length), so heart rate correction is required in the analysis of repolarization duration. Various heart rate cor- rection formulae have been developed in order to determine whether the QTinterval is prolonged in comparison to its pre- dicted value at a reference heart rate of 60...
aPropofol reduces idiopathic prolonged QT interval and QT dispersion during implantation of cardioverter defibrillator. 在cardioverter去纤颤器的安放期间, Propofol减少先天长时期的夸脱间隔时间和夸脱分散作用。[translate] aUltraman beat little monster Ultraman敲打小妖怪[translate] ...
[69]. Notably, a recent retrospective chart review on 55 patients with cutaneous sarcoidosis found a prolonged QT interval only in 5.4% of patients (vs 12.1% in 116 controls), with a non-significant increase in mean QT length (+ 6 ms) in a sub-analysis of 22 patients [70]. Another ...
Heart palpitations occur when methadone is combined with haloperidol, as this combination results in a prolonged QT interval over 500ms. 55μM of fluoxetine reduces the enzyme breakdown of methadone by 50%, resulting in higher levels of circulating methadone and respiratory depression [15]. ...
Therefore, monitoring of liver function tests is recommended before and during treatment. Very rarely, prolongation of QT or QTc interval and torsades de pointes have been reported. Posaconazole is pregnancy category C and has not been studied in pregnant women. Administration of another azole, ...
Prolonged use of hydromorphone during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Hydromorphone is excreted in breast milk; use is not recommended...
NMS is more common with first-generation antipsychotics, but all antipsychotic medications can cause NMS [1]. Heart conditions Antipsychotic medications can increase the risk of harm to the heart, including increased or irregular heartbeat and prolonged QT interval [7]. This risk is greater with ...
