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.
Sometimes, left ventricular hypertrophy with tall T waves is easily misdiagnosed as hyperkalemia and hyperacute T waves, and ECG needs to be carefully identified in combination with clinic.
Torsade de pointes refers to the pleomorphic ventricular tachycardia that occurs in the background of long QT interval, and the polarity of QRS wave twists around the equipotential line.
A 4-year-old boy with a clinical diagnosis of long QT syndrome. No genetic testing was done during hospitalization. The child died suddenly during follow-up.
A 4-year-old boy with a clinical diagnosis of long QT syndrome. No genetic testing was done during hospitalization. The child died suddenly during follow-up.
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.
A 4-year-old boy with a clinical diagnosis of long QT syndrome. No genetic testing was done during hospitalization. The child died suddenly during follow-up.
T wave inversion is a common ECG phenomenon, which can be a normal ECG phenomenon and is more common in structural heart disease.
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.
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.
3D illustration of an electrocardiogram (ECG) showing prolonged QT interval with broad-based T-waves, characteristic of type 1 long QT syndrome.
Bidirectional ventricular tachycardia is a kind of malignant arrhythmia. The polarity of QRS main wave alternates from beat to beat, and it is easy to degenerate into ventricular fibrillation.

Normal T waves are asymmetrical. Coronary T waves are not absolutely symmetric, but increase in symmetry. From the bottom of the T wave to the bottom, the asymmetry gradually increases.
