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 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.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When the limb leads are reversed, it is common for the left upper limb and the right upper limb to be reversed, affecting the ECG pattern of the limb leads.
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.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
The PR interval of an adult ECG is less than 120 ms, which is called a short PR interval.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
When the limb leads are reversed, it is common for the left upper limb and the right upper limb to be reversed, affecting the ECG pattern of the limb leads.
