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. As noted above, the transition from...
V2,V3 and even up to V4)ofpediatricpatients. In an otherwise healthy child(with no heart murmur)—this finding represents abenignnormal variant(referred to as a"Juvenile" T Wave Pattern). However, thesameECG (with identical T wave inversion...
T-wave corresponds to the phase of rapid repolarization of the ventricular action potential. In the 12-lead ECG of adults, the normal T-wave is inverted in aVR; upright or inverted in leads aVL, III, and V1; and upright in limb leads I, and II, and in V3 to V6. Sometimes also ...

A readily available ECG parameter that has recently gained attention is the QRS‐T angle. It is the angle between the axis of the QRS complex and the axis of the T‐wave and represents a measure of cardiac depolariza...
Normal ECG waves and intervals P wave The P wave is the first deflection on the ECG and represents atrial depolarization. The normal electrical impulse originates in the sinoatrial (SA) node which is in the upper right atrium, at the junction of the crista terminalis and superior vena cava....
Fill in the blank: Normally, the T wave on an ECG has a positive deflection of about ___ mV. T Wave: In an electrocardiogram, the T wave represents ventricular repolarization. Ventricular polarization refers to when the muscle cells of the ventricles contract to pump...
Introduction:\nRight bundle branch block (RBBB) is the most common His-Purkinje conduction abnormality seen on ECG. It is currently unclear if there are any quantitative ECG differences in RBBB without and with structural right ventricular (RV) disease. Our aim was to evaluate quantitative ECG ...
Label each axis, and label and describe the P wave (atrial depolarization/contraction), QRS wave (ventricular depolarization/contraction), and T wave (ventricular repolarization/relaxation). Identify the waveforms in a normal electrocardiogram (EC...
while the T-wave represents their electrical recovery. The ST segment is a relatively quiescent period. It has been found that the T-wave is the best interval of the ECG complex for detecting alternans. That is, a level of variation in the T-waves of alternating beats is the best indicato...
