Peak t wave criteria
WebIn some normal individuals, particularly women, the T wave is symmetrical and a distinct, horizontal ST segment is present. The normal T wave is usually in the same direction as the QRS except in the right precordial leads. In the normal ECG the T wave is always upright in leads I, II, V3-6, and always inverted in lead aVR. WebJul 7, 2024 · a) P wave: Normally it is 2.5 mm wide and 2.5 mm high. Tall P waves indicate RA enlargement (RAE), wide P waves indicate LA enlargement (LAE), wide and bi-peaked P waves indicates bi-atrial enlargement (BAE). b) PR interval varies with age and heart rate and is <0.2 sec at any age c) QRS duration (2-3 small squares or 0.08-0.12 sec).
