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.

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.

A 14-year-old leukemic child had a sudden wide QRS tachycardia with a frequency of 167 bpm, and the rhythm was regular. After anti-arrhythmia treatment, the patient recovered to sinus rhythm.

The larger the left ventricular volume and the closer the distance between the left ventricular wall and the chest wall, the greater the amplitude of R wave in the left chest lead, and vice versa.
In the first degree of atrioventricular block, the PR interval was prolonged by more than 200ms, and there was no QRS wave loss in ECG. The blocking site can occur anywhere in the conduction system.
The electrocardiogram diagnosis of first-degree atrioventricular block is relatively simple, with an adult PR interval greater than 200ms and no QRS wave shedding.
Under the background of sinus rhythm, if the difference of P-P interval is less than 120ms, it can be considered that the rhythm is basically regular and can not be diagnosed as sinus arrhythmia.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When QRS wave is multi-component in V1 lead and notch appears in inferior lead, it is highly suggested that the subject may suffer from atrial septal defect.
Sometimes, there may be slight non-specific changes and normal variations in the electrocardiogram, which are often due to physiological reasons and have no clinical therapeutic significance.

Male, 38 years old. There is no history of tachycardia in clinical practice. Electrocardiogram diagnosis: Sinus rhythm; Short PR interval; Early repolarization.
