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?. ...
Although a QT interval of at least 500 milliseconds generally has been shown to correlate with a higher risk of torsades de pointes, there is no established threshold below which prolongation of the QT interval is considered free of proarrhythmic risk. The risk of torsades de pointes should be...
whether the QTinterval is prolonged in comparison to its pre- dicted value at a reference heart rate of 60 beats/min (i.e., an TABLE 1 QT-Heart Rate Correction Formulas 1 Method Formula Comment Exponential Bazett QTc = QT/RR 1/2 Widely used; may give erroneous results at both slow an...
This maximum is believed to provide a more meaningful indicator of the underlying rate of aging because the average life span may be prolonged entirely because of an optimization of the maintenance conditions rather than a slowdown of the rate of aging. It is worthwhile to note that it has ...

Vascular eye-based measures are considered a proxy for the status of the cerebrovascular system,73,74 which is assumed to play, among other factors, a vital role in the positive relationship between physical activity and fitness and measures of cognitive performance.13,34,36,75 Various approaches...
In the past, asthma was considered mainly as a childhood disease. However, asthma is an important cause of morbidity and mortality in the elderly nowadays. In addition, the burden of asthma is more significant in the elderly than in their younger counter
Some side-effects were reported based on isolated case reports and their consistent relationship to the KD is unknown (e.g., cardiomyopathy, prolonged QT interval syndrome, acute pancreatitis, hepatic dysfunction, valproic acid hepatotoxicity, susceptibility to infection, hypoproteinemia) [21]. Quite ...
