Long QT syndrome (LQTS) is a heart rhythm condition that can potentially cause fast, chaotic heartbeats. These rapid heartbeats might trigger a sudden fainting spell or seizure. In some cases, the heart can beat erratically for so long that it causes sudden death. You can have a genetic mutation that puts you at risk of being born with congenital long QT syndrome. In addition, certain medications, imbalances of the body's salts and minerals (electrolyte abnormalities), and medical conditions might cause acquired long QT syndrome. You might need to take medications to prevent an erratic heart rhythm. In some cases, treatment for long QT syndrome involves surgery or an implantable device. You'll also need to avoid certain medications that could trigger your long QT syndrome.

Caution, Drug Interaction QTc prolongation cisapride or droperidol for gastroparesis with citalopram Diagnostic Confusion Delay in gastric emptying; hold TCAs for 48–72 h In 2011, the labeling for the antidepressant citalopram, a selective serotonin reuptake inhibitor SSRI, was updated to include a warning about the risk of QTc prolongation with higher doses.

Thompson, Pharm D Clinical Pharmacist Columbus Regional Healthcare System Columbus , Georgia Ryan R. Crossman, Pharm D Pharmacy Practice Resident Columbus Regional Healthcare System Columbus , Georgia Predicting the risks involved with most of these drugs is difficult, since they are often structurally and pharmacologically unrelated. However, a patient's risk of a fatal ventricular arrhythmia may be reduced with the pharmacist's awareness of nonpharmacologic risk factors, drugs known to cause QT prolongation, and specific drug interactions. The QT interval is the length of time required for the heart to repolarize following the onset of depolarization. Ventricular depolarization, expressed as the QRS complex on an electrocardiogram (ECG), is the rapid movement of ions (sodium, potassium, and calcium) across the cellular membrane, creating electrical impulses that lead to ventricular contraction. When the outflow of potassium from the myocardium exceeds the inflow of sodium and calcium, repolarization occurs and is expressed as the T wave on the ECG. If the ion channels of the myocardium malfunction, most commonly the delayed potassium rectifier channels (IKr), an excess sodium influx or a decreased potassium efflux may result.

Therefore, citalopram should not be used at doses above 40 mg per day. FDA Drug Safety Communication Revised recommendations for.. QT Prolongation Risk Assessed for Non-SSRI Antidepressants. Flupentixol - Wikipedia. Objective To quantify the impact of citalopram and other selective serotonin reuptake inhibitors on corrected QT interval QTc, a marker of risk for ventricular To correct for this, the QT interval is often expressed as the heart rate-corrected QT interval QTc. 1,3 The QTc can be calculated using the Bazett formula, which corrects for heart rate by dividing the QT interval by the square root of the difference between the Rs of two QRS complexes QTc = QT/RR. 1-3 Who have Long qt syndrome with Cymbalta - from FDA reports Long qt syndrome is found among people who take Cymbalta, especially for people who are female, 60+ old, have been taking the drug for 2 - 5 years, also take medication Lorazepam, and have Delirium.
