beta blockers.

These heart medications are standard of care for most people with long QT syndrome. They slow down the heart rate and reduce the likelihood of a long QT episode. Beta-blockers used to treat long QT syndrome include nadolol (Corgard) and propranolol (Inderal LA, InnoPran XL).

What happens to QT interval prolongation?

LQTS occurs due to defects in ion channels that cause a delay in the time it takes for the electrical system to recharge after each heartbeat.It increases when the QT interval is longer than normal Risk of torsades de pointes, a life-threatening ventricular tachycardia.

Why is prolonging QT bad?

If the QT interval is prolonged, Patients may be at risk for ventricular rhythm disturbances. This means, basically, an electrical disturbance in the lower chambers of the heart.

When should the QT interval be corrected?

If the T wave ends beyond the midpoint of the RR interval, it is prolonged. Due to the influence of heart rate, the corrected QT interval (QTc) is often used. QTc is considered to be prolonged If male exceeds 450 ms, female exceeds 470 ms. It is calculated using Bezett’s formula, described below.
