The chest electrode of ECG includes conventional chest lead, posterior wall lead and right ventricular lead. The placement of chest lead electrode shall comply with the specification.
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.
Chest lead is a lead system used to detect the transverse electrical activity of the heart, typically consisting of six electrodes placed in the right and front of the left chest.
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.
When the R wave amplitude of lead V1 in adults exceeds 6mm and there are no organic heart disease or other disease electrocardiogram changes, it is a simple right ventricular high voltage.
In ventricular septal defects, left ventricular hypertrophy, biventricular hypertrophy, or right ventricular hypertrophy ECG may be present.
When sinus arrest occurs, the electrocardiogram will show a long P-P interval, which is not multiples of the basal sinus cycle, including physiological and pathological reasons.
Sometimes, the amplitude of sinus P wave is extremely low, close to equipotential line, and it is easy to be misdiagnosed as junctional rhythm.
In the first degree of atrioventricular block, the PR interval was prolonged by more than 200ms, and there was no QRS wave loss in ECG. The blocking site can occur anywhere in the conduction system.
The electrocardiogram diagnosis of first-degree atrioventricular block is relatively simple, with an adult PR interval greater than 200ms and no QRS wave shedding.
Male, 71 years old, was clinically diagnosed with upper gastrointestinal bleeding. During sleep at night, ECG monitoring showed sinus bradycardia, blood pressure 115 and 70mmHg.
Patients with ventricular septal defects have left ventricular hypertrophy in the early stage and biventricular hypertrophy in the middle and late stages.

In the first degree of atrioventricular block, the PR interval was prolonged by more than 200ms, and there was no QRS wave loss in ECG. The blocking site can occur anywhere in the conduction system.
Simple left ventricular high voltage has no abnormalities such as left atrial abnormality, left axis deviation and ST-T change, but the amplitude of R wave in left chest lead is increased.
Ventricular high voltage refers to an increase in R-wave amplitude, which can be both a normal variation and an electrocardiographic indicator of ventricular hypertrophy.
Sometimes, it is necessary to place electrodes in the high intercostal space at the conventional chest lead electrode placement position, which is called a high intercostal chest lead.
In frontal lead system, anatomical transposition and electrical transposition are not in good agreement, because some electrical transposition has nothing to do with anatomy.
The atrial foci originating from the anterior and posterior walls of the right atrium form an inverted P wave and positive and negative biphasic P wave in the V1 lead, respectively.
Male, 75 years old, clinically diagnosed as acute anterior septal and high lateral myocardial infarction.The culprit vessel was located in the LAD proximal segment.Prolonged QT interval with TDP.
In the conventional 12 lead ECG, the chest lead system represents the electrical activity in the transverse or horizontal plane, and there are 6 traditional leads.

Ventricular tachyarrhythmia includes many clinical types, some benign and some malignant. For malignant ventricular arrhythmias, patients are at risk of death.
