Arrhythmia Atrial fibrillation Large-wave

Large-wave atrial fibrillation (WCA) is a special type of arrhythmia, which is characterized by the presence on the electrocardiogram (ECG) of relatively large and rare (300-500 per minute) atrial fibrillation waves. This form of arrhythmia is usually observed with heart defects with atrial overload.

Arrhythmias include various heart rhythm disorders that can occur due to problems with the conduction of electrical impulses in the heart. Arrhythmias can vary in type and severity, and their diagnosis and treatment require specialized medical attention.

Atrial fibrillation is one of the most common types of arrhythmias. It is characterized by a fast and irregular heart rhythm that is caused by abnormal electrical impulses generated in the atria. In the case of atrial fibrillation MCV, these impulses have relatively large and sparse waves on the ECG.

Atrial fibrillation is usually associated with heart defects that cause overload of the atria. Atrial congestion means that the atria are under excessive strain due to the volume of blood that collects in them or because of abnormalities in their structure. This can be caused by conditions such as mitral stenosis (narrowing of the mitral valve) or atrioventricular defective line (a defect characterized by the presence of an additional opening between the atria and ventricles).

Doctors use an ECG to diagnose atrial fibrillation. The ECG shows irregular atrial fibrillation with characteristic large and sparse waves. Additional diagnostic methods may include monitoring symptoms and other cardiac tests.

Treatment for MVC arrhythmia aims to control the heart rhythm and prevent serious complications such as thromboembolic events or heart failure. Doctors may recommend a variety of treatments, including antiarrhythmic medications, electrical cardioversion (a procedure in which the heart is pumped with an electrical pulse), an implantable cardioverter defibrillator, or surgery to ablate (destroy) abnormal electrical pathways in the heart.

The prognosis for patients with atrial fibrillation MVC depends on the severity of the arrhythmia and the presence of concomitant diseases. Timely consultation with a doctor and proper treatment can significantly improve the patient’s prognosis and quality of life.

In conclusion, MVC atrial fibrillation is a special type of arrhythmia characterized by the presence of large and sparse atrial fibrillation waves on the ECG. It usually occurs with heart defects with atrial overload and requires a specialized approach to diagnosis and treatment. Early consultation with a doctor and following specialist recommendations will help control arrhythmia and maintain cardiovascular health.

Arrhythmia is a disturbance in the rhythm of heart contractions. Occurs when the formation, conduction or interaction of nerve impulses is disrupted. Ventricular arrhythmias and atrial rhythm disturbances are distinguished. **Atrial fibrillation** is characterized by the fact that impulses during an attack of arrhythmia excite the atria, which leads to the development of arrhythmic contraction of the atrial muscle. The work of the ventricles is not impaired, since their impulse comes from the sinus node without pauses. Thus, the contractions of the ventricles and atria are irregular, but have approximately the same frequency. **Large-wave arrhythmias** progress too quickly, with one heartbeat followed by another without sufficient ST-segment warning. For this reason, they can lead to ischemia in the heart muscle. A feature of arrhythmia **is a large wave (usually >=6 cycles) with the appearance of a jagged rhythm**. It can be either left (with predominance of the left ventricle) or right.

Signs that can be detected in a patient with arrhythmia:

tachycardia - heart rate increases, that is, the amount
