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.
Ventricular tachyarrhythmia includes many clinical types, some benign and some malignant. For malignant ventricular arrhythmias, patients are at risk of death.
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.
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.
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.
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.
A 36 year old man survived CPR after sudden syncope. The electrocardiogram was suggestive of Brugada syndrome type 1. Implantation of ICD therapy.
A normal electrocardiogram includes normal morphology, amplitude, and various measurements of duration and interval, normal electrical axis, and normal R wave progression.
Electric impulses can be conducted, but the conduction speed slows down, resulting in conduction delay and affecting the morphology of the P wave, PR interval, and QRS wave.
In the frontal plane lead system, when the initial vector of the QRS wave is directed downward, the positive initial QRS wave is recorded in leads II, III, and aVF.
The upper limit value of R wave amplitude in each lead of ECG is related to age, sex, body shape, etc. Here are the ECG data of Japanese adults.
Male, 84 years old, admitted to hospital with chest pain for 1 day. ECG showed acute inferior and posterior MI and possibly right MI. The patient died of ventricular fibrillation the next day.
When acute left main artery occlusion causes ST segment elevation myocardial infarction, it is often accompanied by extensive anterior and high lateral myocardial infarction.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.
When intermittent conduction dysfunction occurs in the Bachmann bundle, intermittent left atrial abnormality may be seen on the ECG, which can be differentiated from anatomical left atrial enlargement.
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.
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.
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.
In the spatial anatomy of the heart, the axis from the base of the heart to the apex of the heart is called the long axis, that is, the upper right side faces the lower left side.
The larger the left ventricular volume and the closer the distance between the left ventricular wall and the chest wall, the greater the amplitude of R wave in the left chest lead, and vice versa.
Four anatomical malformations of tetralogy of Fallot: 1 aortic straddling; 2 ventricular septal defect; 3 right ventricular hypertrophy and 4 pulmonary artery stenosis.
A patient with acute inferior and anterior myocardial infarction(MI) caused by distal occlusion of the RCA and one day later, combined with occlusion of the LAD, caused high lateral and anterior MI.
In the aVR lead, the QRS wave can be in the form of QS, rS, Qr, rsr, etc., with the main wave being negative.
Some measured values of ECG have differences in gender, age and race, for example, the QRS wave amplitude of Chinese is different from that of Caucasians.
Second degree rinteratrial block includes two types: type 1 block with progressive worsening of conduction and interruption of conduction, and type 2 block with fixed conduction and interruption.
Under the background of sinus rhythm, if the difference of P-P interval is less than 120ms, it can be considered that the rhythm is basically regular and can not be diagnosed as sinus arrhythmia.
Some patients with severe sinus bradycardia have triggers that can disappear after treatment, while others are permanent and require treatment with ventricular pacemakers.
Septal q wave loss refers to the initial q wave loss of leads I, aVL, V5, and V6, which can be partially or completely lost.
When the frontal QRS axis is at +83, the R amplitude of lead aVF is the highest.The frontal QRS axis is almost perpendicular to the axis of lead .
Clockwise rotation electrocardiogram refers to the transition of the rS waveform of the chest lead to the left chest lead, with the transition lead exceeding the V4 lead.
In the 12 lead ecg, the highest R wave amplitude is commonly found in the left chest lead, while the lead with the deepest S wave amplitude is commonly found in the right chest lead.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
The accompanying ST-T changing in the context of wide QRS complexes.The wide QRS complex changes the order of ventricular depolarization and secondary changes in the order of repolarization.
When QRS wave is multi-component in V1 lead and notch appears in inferior lead, it is highly suggested that the subject may suffer from atrial septal defect.
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.
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.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
Clockwise and counterclockwise rotation are common electrocardiographic phenomena, mainly used to describe the evolution of R-wave amplitude in chest leads.
When Bachmann bundle conduction is interrupted, the right atrium excites the left atrium through the coronary sinus, producing positive and negative biphasic P-waves in the inferior leads.
In the frontal lead system, when the initial vector of the QRS wave points upward, the II, III, and aVF leads record a negative initial QRS wave, i.e., a small q wave.
Female, 6 years old, clinically diagnosed with Tetralogy of Fallot. The electrocardiogram shows sinus rhythm, extreme right axis deviation, biatria abnormality, right ventricular hypertrophy, etc.
Male, 13 years old, clinically diagnosed with secundum atrial septal defect. Note that the QRS wave in lead V1 of the electrocardiogram has a qR shape, indicating right ventricular hypertrophy.
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.
Sometimes, there may be slight non-specific changes and normal variations in the electrocardiogram, which are often due to physiological reasons and have no clinical therapeutic significance.
Abnormal ECG refers to changes in depolarization waves and or repolarization waves, most of which are pathologic and few are physiological.
The high lateral lead group includes leads I and aVL, used to explore the myocardium of the high lateralwall of the left ventricle.
Female, 5-year-old, clinically diagnosed with dextrocardia. The characteristic of dextrocardia electrocardiogram is a gradual decrease in R-wave amplitude from leads V1 to V6.
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.
