Physiology: : The T wave represents ventricular repolarization. Morphology Shape: asymmetrical, with the downward slope steeper than the initial upward slope Amplitude: < 10 mm (between 1/8 and 2/3 of the R wave) Polarity: physiologically concordant to the QRS complex (positive if the QRS ...

Loss of precordial T-wave balance Loss of precordial T-wave balance occurs when the upright T wave is larger than that in V6. This is a type ofhyperacute T wave. The normal T wave in V1 is inverted. An upright T wave in V1 is considered abnormal — especially if it is tall (...
T wave amplitudeventricular action potentialThe T wave seen on the surface ECG represents the repolarization of the ventricular action potential. The amplitude of the T wave is usually most positive in the anterior leads, specifically V2 or V3. The upper limits of normal for positive T wave ...
T Wave – represents the repolarization of the ventricles. Note: The repolarization of the atrial chambers is obscured by the depolarization of the ventricles and is thus not specifically represented within the ECG complex. ECG Solutions from DSI ...
QRS波群终点至T波起点间的等电位线,反映心室复极的2相平台期。代表心室除极完毕到复极开始的一段时间。ST段在任何导联压低不应超过0.05mV,抬高不应超过0.1mV(V1～V3导联除外)。 T wave The T wave represents ventricular repolarization. The direction of normal T wave is consistent with QRS wave. T wave...
The T wave represents ventricular repolarization, and marks the beginning of ventricular diastole. An ECG can convey a large amount of information about the structure of the heart and the function of its underlying conduction system, including: the rate and rhythm of heartbeats, the size and posi...
The T wave represents the ventricular repolarization of the ventricles.On rare occasions, a U wave can be seen following the T wave. The U wave is believed to be related to the last remnants of ventricular repolarization. 心脏周期:典型的ECG心跳包括P波,QRS复合波和T波。 P波代表从SA节点扩展...
The T wave represents the recovery phase, in which the electrical current spreads back over the ventricles in the opposite direction. The heart, seen on the left, is beating in time with the ECG. Oxygen-depleted (blue) blood is pumped from the heart to the lungs, which supply oxygen. ...
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...
