Is QTc accurate in AFIB?

QTc was overestimated in AF compared to SR when using Bazett’s formula (ΔQTc = 14.28 ms, 95 \% CI 11.25 to 17.31, p <0.001) and Hodges formula (ΔQTc = 7.52 ms, 95\% CI 4.83 to 10.21, p <0.001).

What is long QT syndrome (LQTS)?

Long QT syndrome (LQTS) is a disease that can cause a dangerous rapid heart rate and irregular rhythm involving the bottom pumping chambers of the heart (ventricles). The heart has both muscular and electrical components. Electricity flowing through the heart muscle triggers the muscle to squeeze (contract) or beat.

What is LQTS and why is it so dangerous?

In LQTS, a problem in the ion channels leads to an upset in the flow of electricity that causes a prolonged “repolarizing” of the heart cells. This delay means the heart isn’t ready for the next beat. This can create a set-up for a very rapid and dangerous heart rhythm (arrhythmia) that may cause fainting or sudden death.

What is the prevalence of LQTS in the US?

When the Q-T interval is longer than normal, it increases the risk for torsade de pointes, a life-threatening form of ventricular tachycardia. LQTS is rare. The prevalence is about 1 in 5,000 persons in the United States. Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission.
