Sudden Death
Death
Ventricular Tachycardia - is fast heart rhythm, that originates in one of the ventricles of the heart. This is a potentially life-threatening arrhythmia because it may lead to ventricular fibrillation, asystole, and sudden death

sudden death word in a dictionary. sudden death concept.
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.
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.
During left posterior fascicular block, the ECG showed right axis deviation. The QRS wave in leads I and aVL was rS wave, and the duration of QRS wave was less than 120 ms.
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.
Male, 60 years old, clinically diagnosed as acute extensive anterior wall myocardial infarction. The patient died of ventricular fibrillation after admission.
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.
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.
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.
Cardiac Death through Stress
Female, 51 years old, diagnosed with mitral stenosis. When this ECG was taken, the patient still maintained sinus rhythm.Note that the P wave duration was widened.
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.

A 36 year old man survived CPR after sudden syncope. The electrocardiogram was suggestive of Brugada syndrome type 1. Implantation of ICD therapy.

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.
In complete left bundle branch block, the conduction of the LBB can be completely interrupted or can still be conducted, but it is delayed by at least 45ms than the RBB.
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.
Learning cardio system concept. Chalk drawing of human heart and inscription Sudden death
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.
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.
Male, 52 years old, diagnosed with acute extensive anterior wall myocardial infarction. The patient repeatedly experienced ventricular tachycardia and eventually died of cardiogenic shock.
Under physiological conditions, T waves in leads III, aVL, and V1 can exhibit inversion However, sometimes it is necessary to differentiate it from pathological T wave inversion.
Male, 65 years old, admitted with chest pain for 2 hours. Coronary angiography indicates subtotal occlusion of the proximal to middle segment of the left anterior descending artery.
A patient with AIMI presents with a sudden widening of the QRS complex in the junctional escape rhythm, premature ventricular contractions, resulting in polymorphic ventricular tachycardia.
When ectopic impulses from the anterior wall of the right atrium produce a completely negative P wave in lead V1, the posterior wall ectopic impulse produces a positive and negative biphasic P wave.
Atrial focal originating in the left upper pulmonary vein, with an upright P wave in V1 and wide duration, inverted P wave in lead aVL and an upright P wave with notch in inferior leads.
The standard for diagnosing right atrial abnormality in ECG is that the amplitude of P-wave in limb leadsI is greater than 2.5mm, and the amplitude of upright P-wave in chest leads is 1.5mm.
When the duration of a ventricular tachycardia attack exceeds 30 seconds or is less than 30 seconds accompanied by circulatory instability, it is called persistent ventricular tachycardia.
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.
The ECG changes of left atrium abnormality include widening of P wave duration, bimodal P wave and increasing of P wave terminal potential in lead V1 lead P wave.
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, 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.
Third degree atrioventricular block in young women may be congenital, with the block located on the atrioventricular node or above bifurcation of the His bundle.
When the rhythm of the atria originates in the lower part of the atria, the whole atria are excited from inferior to superior, producing negative P waves in the inferior leads.
Male, 84 years old, admitted to hospital with chest pain for 1 day. These ECG rhythms are the Holter monitor records of the patients after admission, and they are third degree atrioventricular block.
When the left ventricle dilates, the amplitude of the QRS wave increases, and the electrocardiogram can diagnose left ventricular hypertrophy, which is essentially enlargement of the heart cavity.
Third degree atrioventricular block in young women may be congenital, with the block located on the atrioventricular node or above bifurcation of the His bundle.
Third degree atrioventricular block in young women may be congenital, with the block located on the atrioventricular node or above bifurcation of the His bundle.
Four anatomical malformations of tetralogy of Fallot: 1 aortic straddling; 2 ventricular septal defect; 3 right ventricular hypertrophy and 4 pulmonary artery stenosis.
