Antidepressant Link To Heart Rhythm Abnormalities No Cause For Alarm
Some antidepressants have been linked to a long QT, which may increase the likelihood of having a serious heart rhythm abnormality. However, as they are extremely rare, the benefits offered by antidepressant far outweigh the risks and patients should not be alarmed, says the British Heart Foundation. American scientists demonstrated an association between the antidepressants citalopram and escitalopram and a long QT interval in some patients' ECGs (electrocardiograms). They reported their findings in the BMJ (British Medical Journal)... (Source: Health News from Medical News Today)

Some Antidepressants May Cause Heart Rhythm Problems, Study Confirms
SSRIs (selective serotonin reuptake inhibitors), types of antidepressants, are associated with a long QT interval, researchers from Massachusetts General Hospital, Boston, reported in the BMJ (British Medical Journal). The QT interval is the duration of electrical activity of the heart muscle. A long QT interval is a marker for heart rhythm abnormalities. The researchers say that their findings support warnings by the FDA (Food and Drug Administration) about citalopram (Celexa). They add that other antidepressants may have similar effects...

Pharmacovigilance study confirms modest QT interval prolongation with antidepressant use
Source: BMJ Area: News The US Food and Drug Administration issued a warning in 2011 that citalopram had been associated with QT prolongation, based on post-marketing surveillance and a small crossover study. However no studies have explored this risk in general clinical populations, or its specificity for citalopram.   This US cross sectional study explored the relationship between citalopram and other selective serotonin reuptake inhibitors on corrected QT interval (QTc), a marker of risk for ventricular arrhythmia, in a large and diverse clinical population.   A total of 38,397 adult patients with an e...

Antidepressant contribution to arrhythmia risk clarified

Popular Antidepressants May Put Patients At Risk For Serious Arrhythmias
In August 2011 the FDA issued a safety communication recommending that the extremely popular antidepressant citalopram (Celexa) not be used at doses greater than 40 mg/day because of a potential increased risk for serious cardiac arrhythmias associated with prolongation of the QT interval. Now a study published in BMJ lends support to this warning and suggests that other antidepressants may also prolong the QT interval. (Source: Forbes.com Healthcare News)
