Sinus bradycardia <40 bpm, Mobitz type 1 second degree AVB and junctional rhythm are not uncommon and don't warrant further investigation in asymptomatic athletes. Mitral regurgitation (backward Type 1 Brugada ECG pattern (coved type) is abnormal. Anterior wall infarctions, on the other hand, generally leave permanent bradycardia and thus demand permanent pacemaker.

As forventricular enlargement, the ECG cannot differentiate dilatation from hypertrophy, which is why some experts have suggested that the termatrial abnormality be used instead of enlargement. MeSH References: [9] By approximating the shape of the left atrium as an ellipsoid, its volume can be calculated from measurements of its dimensions along three perpendicular directions. The juvenile ECG pattern (T-wave inversion in leads V1-V3) is acceptable up to age 16 years. These tracings are recordings of the rhythm of the heart.
