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.

HealthDay News -- Three antidepressents have been associated with prolonged corrected QT QTc interval -- a marker of increased ventricular arrhythmia risk, study results show. Two selective serotonin reuptake inhibitors, citalopram and escitalopram, and the tricyclic antidepressant amitriptyline. Duloxetine is a selective serotonin and norepinephrine reuptake inhibitor antidepressant SSNRI. Duloxetine affects chemicals in the brain that may be unbalanced in people with depression. Duloxetine is used to treat major depressive disorder in adults. Internet Explorer 8.0 and older will automatically be redirected to this legacy version.

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.
