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.
Electromechanical separation is a kind of terminal ECG. The patient's ECG has electrical signals, the ECG wave is widened with morphological abnormalities, and the ventricle has no contraction.
A patient with acute extensive anterior myocardial infarction developed ventricular tachycardia during hospitalization and quickly experienced cardiac arrest.
The illustration shows the two patterns of ventricular tachycardia episodes.The green circle represents sinus rhythm. Picture A shows paroxysmal episodes of ventricular tachycardia, and picture B shows short bursts.
When acute left main artery occlusion causes ST segment elevation myocardial infarction, it is often accompanied by extensive anterior and high lateral myocardial infarction.
Early afterdepolarization is an arrhythmogenic mechanism that triggers activity, occurring before the end of the T wave and commonly seen in QT interval prolongation.
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.
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.
In case of acute anterior myocardial infarction, the characteristics of ST segment elevation in ECG can be used to deduce whether the culprit vessel system is the left main trunk or the proximal LAD.
When acute left main artery occlusion causes ST segment elevation myocardial infarction, it is often accompanied by extensive anterior and high lateral myocardial infarction.
