Most patients with drug-induced QT prolongation are asymptomatic and are diagnosed solely by EKG in association with a history of using medications known to cause QT prolongation. [7] A minority of patients are symptomatic and typically present with one or more signs of arrhythmia, such as lightheadedness, syncope, or palpitations. [7]
AZCERT focuses on drugs and drug–drug interactions, especially those that cause QT prolongation and Torsades de Pointes (TdP) arrhythmia, and provides its research and its lists of drugs [10] free of charge to the public, healthcare providers, and researchers for personal, professional, and non-commercial purposes. To maintain the ...
Although long QT syndrome is often a genetic condition, a prolonged QT interval associated with an increased risk of abnormal heart rhythms can also occur in people without a genetic abnormality, commonly due to a side effect of medications. Drug-induced QT prolongation is often a result of treatment by antiarrhythmic drugs such as amiodarone ...
It can be caused by certain drug interactions, as well as drinking alcohol while taking a medication like Lexapro. ... If you have a history of heart problems — such as QT prolongation and heart ...
The mechanism of action of certain antiarrhythmic drugs, like amiodarone or sotalol, involve intentional pharmacological QT prolongation. In addition, high blood alcohol concentrations prolong the QT interval. [30] A possible interaction between selective serotonin reuptake inhibitors and thiazide diuretics is associated with QT prolongation. [31]
Compounds that prolong the action potential: matching the modern classification, with the key drug example being amiodarone, and a surgical example being thyroidectomy. This was not a defining characteristic in an earlier review by Charlier et al. (1968), [ 17 ] but was supported by experimental data presented by Vaughan Williams (1970).
Additionally, in clinical trials ranolazine slightly increased QT interval in some patients [13] and the FDA label contains a warning for doctors to beware of this effect in their patients. [10] The drug's effect on the QT interval is increased in the setting of liver dysfunction; thus it is contraindicated in persons with mild to severe liver ...
Diversion, abuse, and a relatively high rate of overdose deaths in comparison to other drugs of its group. This drug continues to be available in most of the world including the US, but under strict controls. Terfenadine (Seldane, Triludan) 1997–1998 France, South Africa, Oman, others, US Prolonged QT interval; ventricular tachycardia [2] [3]
