Hypertension. Aging itself causes left atrial growth, probably in relation to structural changes in the atrial tissue. T-wave inversions in leads V1-V4 are present in 12% of black athletes and are usually preceded by J-point elevation and convex ST segment elevation. Interpretation of neonatal and pediatric electrocardiograms (ECG) If a Type 2 pattern is seen, the ECG needs to repeated to ensure proper lead placement, and a repeat ECG with V1 and V2 in higher intercostal leads should be performed: if there is no evidence of a Type 1 Brugada pattern, no further assessment is required unless there is a history of syncope or relevant family history. A pathological Q-wave (depth exceeding 25% of the height of proceeding R wave) is abnormal. If severe mitral regurgitation resulting from a floppy mitral leaflet, rupture of the chordae tendineae, or extreme lengthening of the valve should occur, surgical repair may be indicated. could the abnormal been anxiety produced?, and is it something to be worried about?
