What is the portion of the ECG that indicates ventricular repolarization?
The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
How does the structure of earths interior affect the wave speed and direction of seismic waves?

Atrial repolarization coincides in time with?
the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.
Why T wave is in same direction of QRS wave in ECG?
The T wave in an ECG is typically in the same direction as the QRS complex because both represent ventricular depolarization and repolarization, respectively. During the QRS complex, the ventricles depolarize, and then during the T wave, they repolarize, leading to the similar orientation of the waves.
Is Lvh with repolarization abnormality dangerous?
LVH (left ventricular hypertrophy) is represented by classic EKG findings, namely that the sum of V1Q and V5R > 35 mm (ie: a very deep Q wave in V1 and a very tall R wave in V5). Further, you will expect to find left axis deviation as represented by tall R waves in both lead II and aVL. LVH is one of many conditions (including bundle branch blocks) that can also have repolarization abnormalities. Simply put, a repolarization abnormality is shown on EKG with a T wave going the opposite direction as the main direction of the QRS. Recall, normally these will be in the same direction despite the fact that the QRS is ventricular depolarization and the T wave is ventricular repolarization, because they occur in opposite directions.
The T wave tracing measures atrial repolarization?
The T wave on an electrocardiogram (ECG) actually represents ventricular repolarization, not atrial repolarization. Atrial repolarization occurs during the QRS complex and is typically not visible on the ECG due to the larger electrical activity of the ventricles. The T wave reflects the recovery phase of the ventricles after they have contracted and is crucial for understanding cardiac function.
What does the t wave represent on an ecg?
It represents the repolorization of the ventricles. The ventricles must reset electrically after contracting. In a normal Sinus Rhythm the p wave comes first. Then the QRS complex which is the largest part of the heartbeat will come less than .2 seconds later. The QRS complex usually lasts less than .12 seconds. The final bump is (usually) the T wave.
