Prolonged QTc interval, pericardial effusion and diastolic dysfunction are associated with higher mortality.

A prolonged QT interval has a variety of causes and can be a very serious ECG finding, as it may lead to the potentially fatal arrhythmia polymorphic ventricular tachycardia (Torsades de Pointes).

Lower heart rates also result in a longer QT interval. A quick way to distinguish a prolonged QT interval is to examine if the T wave ends beyond the halfway point between the RR interval.

Long QT syndrome (LQTS ... the QT interval corrected for heart rate (QTc interval) actually increased by 50 ± 30 ms. By contrast, the QT interval did not decrease in patients with LQTS (it ...

A significantly prolonged QT interval increases the risk of arrhythmias, which can sometimes lead to sudden cardiac arrest. Additional risk factors, such as pre-existing heart conditions ...

The likely mechanism for both increased rigidity of the cardiac chambers leading on to impaired cardiac filling and thus causing diastolic dysfunction as well as prolonged OTc interval is possibly ...
