WebHealthcare providers measure heartbeats on an electrocardiogram (ECG). This test evaluates your heart’s electrical signals. On the ECG, specific voltage waves — called P, Q, R, S and T — mark each heartbeat. When blood flows through your heart, it moves from your top right heart chamber (atrium) to your bottom right heart chamber (ventricle). WebJul 1, 2024 · WHAT IS NORMAL? The definition of the lower limit of the normal QT interval is a matter of debate. Mason et al 4 analyzed the electrocardiograms of 79,743 healthy people (including babies and children) and found that a QTc value 2 standard deviations below the mean was 350 ms in males and 360 ms in females.
