The ventricles are the lower chambers of the heart. The human heart has 2 ventricles, the right ventricle receives blood from the right atrium and pumps it to the lungs through the pulmonary artery. The left ventricle receives blood from the left atrium and pumps it into the circulatory system through the aorta.

Ventricular arrhythmia is a type of arrhythmia that causes the heart to beat at an abnormally fast rate. If not detected and treated promptly, ventricular arrhythmias can be life-threatening.

Aortic valve stenosis is a dangerous heart valve disease with a high incidence, especially in the elderly. What causes aortic valve stenosis? How to vet? The following article will help you better understand this disease.

The heart plays an important role in the cardiovascular system, which includes all the blood vessels that carry blood from the heart to the body, and then back to the heart. So how does blood flow through the heart?

Gene mutations that are associated with abnormalities in cardiac repolarization lead to prolongation of the QT interval on the electrocardiogram, also known as congenital long QT syndrome. Patients with congenital long QT syndrome are at increased risk of ventricular arrhythmias and sudden death.

Acquired long QT syndrome is a cardiac repolarization disorder characterized by acquired QT interval prolongation on the electrocardiogram. This is often caused by drug and electrolyte abnormalities that can trigger torsades de pointes ventricular arrhythmias.

Ventricular arrhythmias are one of the most common types of cardiac arrhythmias. The variable heart rate originates supraventricularly with different foci of pacing, mainly originating in the atria. The disease has many causes and is mainly due to cardiovascular diseases.

With the exception of aortic valve disease, ventricular septal defect is the most common congenital heart disease, accounting for about 25% of congenital heart diseases. Children with this malformation are often slow to grow and can have many dangerous complications if not handled promptly. This article will provide you with knowledge about ventricular septal defect to be more proactive in dealing with this disease.

Currently, ventricular septal defect accounts for 15-20% of all congenital heart diseases. The following article will outline some of the complications of ventricular septal defect and the most effective treatment methods.
