3D illustration of an electrocardiogram (ECG) showing prolonged QT interval with broad-based T-waves, characteristic of type 1 long QT syndrome.
A normal electrocardiogram includes normal morphology, amplitude, and various measurements of duration and interval, normal electrical axis, and normal R wave progression.
At present, there is a younger trend in patients with acute myocardial infarction, so it is important to check the ECG for acute chest pain in young people.
Hypoplastic left heart syndrome is a rare congenital heart defect in which the left side of the heart is severely underdeveloped.It may affect the left ventricle, aorta, aortic valve, or mitral valve. 3D Render

The accompanying ST-T changing in the context of wide QRS complexes.The wide QRS complex changes the order of ventricular depolarization and secondary changes in the order of repolarization.
Firstly, select point J as the reference point, and then select 60ms after point J as the measurement point to evaluate the ST segment offset morphology and amplitude.
Under physiological conditions, the upward sloping ST segment depression forms a U-shaped curve, where the depressed PR segment, J point, and ST segment form a smooth parabola.
Early repolarization is mostly a benign ECG change, specifically referring to J point and ST segment elevation equal to and greater than 1mm, and a few are malignant, with a risk of cardiac arrest.
Under normal circumstances, notch T waves are more common in leads V2-V3 and are caused by asynchronous local ventricular repolarization.
R wave greater than S wave is judged to be positive; R smaller than S is judged to be negative; R equal to S amplitude is judged to be equipotential.
The QT interval of ECG is from the beginning of QRS wave to the end of T wave, representing the total time of ventricular depolarization and repolarization.
