Ventricular Rhythm Disorders
The heart is an organ composed of four chambers: two atria and two ventricles, located on the left and right sides. The ventricles are the largest chambers.
The articles in this section explore abnormal heart rhythms associated with the ventricles, known as ventricular rhythm disorders.

Ventricular tachycardia: disorganized contractions
Tachycardia refers to an abnormally fast heart rate. It can originate in either the atria or the ventricles. Here, we will focus on the latter condition: ventricular tachycardia. The heart is an organ composed of four chambers: two atria and two ventricles, located on the left and right sides. Each ventricle serves a specific function.…

Ventricular extrasystoles are premature heart contractions
The heart is an organ composed of four chambers: two atria and two ventricles, located on the left and right sides. Each ventricle serves a specific function. The right ventricle contracts and pushes blood into the pulmonary arteries. The left ventricle contracts and pushes blood into the aorta. The oxygen-rich blood is then delivered to…

Ventricular fibrillation: a leading cause of cardiac arrest
The heart is an organ composed of four chambers: two atria and two ventricles, located on the left and right sides. The ventricles, which are involved in this disorder, are the lower chambers. Their function is to contract to pump blood out of the heart and into the arteries. The atria and ventricles contract in…

Junctional tachycardia: the heart in the fast lane
The heart is a muscle that works tirelessly to pump blood throughout our entire body. It consists of four chambers – two atria and two ventricles – and is controlled by a complex electrical system. Like a conductor leading an orchestra, this system sends electrical signals that trigger the rhythmic contraction of the atria and…

Idiopathic ventricular fibrillation
Idiopathic ventricular fibrillation is a rare heart rhythm disorder characterized by the chaotic activity of the heart ventricles. It prevents effective cardiac contraction, causes loss of consciousness in just minutes and, in certain cases, is fatal. Ventricular fibrillation is called “idiopathic” when it occurs in a healthy heart without any identifiable cause to prevent it.…

Sudden cardiac arrest: when the brain doesn’t get enough oxygen
The heart is an organ composed of four chambers: two atria and two ventricles, located on the left and right sides. The ventricles, which are involved in this disorder, are the largest chambers. Their function is to contract to pump blood out of the heart and into the arteries. Cardiac arrest, also known as heart…
