The typical ST-T changing of left ventricular hypertrophy are: ST segment slightly convex with downward sloping depression; fusion of ST segment and inverted T wave; asymmetry of inverted T wave.
Male, 60 years old, clinically diagnosed as acute extensive anterior wall myocardial infarction. The patient died of ventricular fibrillation after admission.
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.
In acute left main occlusion, the left ventricular myocardium is massively ischemic and necrotic, the excitatory potential of the left ventricle is weakened, and the axis may deviate to the right .
Male, 65 years old, was clinically diagnosed with acute anterior myocardial infarction. The patient was treated with a coronary stent, but no reperfusion T wave occurred on day 2.
The presence of ST-segment prolongation and T wave symmetry and high tip on ECG suggests hypocalcemia and hyperkalemia.
During the onset of variant angina pectoris, ECG is divided into non fusion wave, partial fusion wave and complete fusion wave according to the fusion degree of QRS wave, ST segment and T wave.
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.
The left main coronary artery can be divided into the left anterior descending artery and the left circumflex artery, and sometimes the intermediate branch artery.
Coronary artery spasm causes transmural myocardial ischemia, and ST segment elevation in ECG has localization characteristics. Criminal vessels can be derived from ST segment elevation leads in ECG.
In ST segment elevation myocardial infarction, the ST-T of ECG will undergo a characteristic evolution process, and finally appear pathological Q wave, sometimes lasting for a lifetime.
In acute myocardial ischemia, the amplitude of T wave is increased first, and then the ST segment is elevated. When the end of QRS wave is deformed, there is a lack of collateral circulation.
According to the offset amplitude of the ST segment at J point and J60 point, ST segment elevation can be divided into three basic types: concave upward, oblique straight and concave downward type.
White tongue, causes and treatments
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.
Male, 60 years old, clinically diagnosed as acute extensive anterior wall myocardial infarction. The patient died of ventricular fibrillation after admission.
In acute high lateral myocardial infarction, there is indicative ST segment elevation in leads I and aVL, and corresponding ST segment depression in leads II, III and aVF.
When the ST segment is depressed, the amplitude of depression at point J and point J60 can be divided into three types: horizontal (A), downward sloping (B), and upward sloping (C).
The coronary angiography showed complete occlusion of the left main artery, TIMI 0 and no stenosis in the right coronary artery with TIMI 3, and a lateral circulation to left coronary artery.
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.
T wave inversion is a common ECG phenomenon, which can be a normal ECG phenomenon and is more common in structural heart disease.
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.
Sometimes, because the QRS axis is in the upper left quadrant, the high-amplitude R wave of left ventricular hypertrophy occurs in the limb leads, and left chest leads is normal.
