The normal T-wave. Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age.

WAVE OR INTERVAL DURATION (msec) P wave duration – <120 msec; PR interval – <200 msec; QRS duration – <110-120 msec; QT interval (corrected) -≤440-450 msec; Normal Values for Durations of ECG Waves and Intervals in Adults. Normal Values for Durations of ECG Waves and Intervals in Adults
The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age.
T-wave progression should be normal in chest leads. In limb leads the amplitude is highest in lead II, and in the chest leads the amplitude is highest in V2–V3. Common findings. Normal variants: An isolated (single) T-wave inversion is accepted in lead V1 and lead III.
Normally, T waves are upright in all leads, except aVR and V1 leads. Highest amplitude of T wave is found at V2 and V3 leads. The shape of the T wave is usually asymmetrical with a rounded peak. T wave inversions from V2 to V4 leads are frequently found and normal in children.
4 lis 2015 · There are a number of ways to calculate the QT c depending on the actual HR of the patient: Bazett’s Formula (HR 60-100bpm) Federicia’s Formula (HR <60 & >100) The Normal ECG. The normal ECG will display these characteristics: Rhythm <10% variation in RR intervals) Rate. 60- 99bpm; Cardiac Axis-30° – 90° P Waves. 0.2-0.3mV; 0.06 – 0.12s
