Normal computerized Q wave measurements in healthy young athletes.

Background: Recent Expert consensus statements have sought to decrease false positive rates of electrocardiographic abnormalities requiring further evaluation when screening young athletes. These statements are largely based on traditional ECG patterns and have not considered computerized measurements.

Objective: To define the normal limits for Q wave measurements from the digitally recorded ECGs of healthy young athletes.

Optimizing QT Interval Measurement for the Preparticipation Screening of Young Athletes.

Purpose: Sudden cardiac death is the leading cause of death in athletes. Long QT syndrome (LQTS) is one of the most common cardiogenetic diseases that can lead to sudden cardiac death and is identified by QT interval prolongation on an ECG. Recommendations for QT monitoring in athletes are adopted from nonathlete populations.
