kammioventrikulaarinen

Kammioventrikulaarinen refers to a characteristic of the heart's electrical system and its coordination. It describes the process by which the ventricles, the lower chambers of the heart, contract and pump blood. This contraction is triggered by an electrical impulse that travels from the atria to the ventricles. The normal sequence of events is crucial for efficient blood circulation.

The electrical signal originates in the sinoatrial (SA) node, then passes through the atrioventricular (AV) node, and subsequently travels down the bundle of His and Purkinje fibers to the ventricular muscle. This structured pathway ensures that the ventricles contract in a coordinated manner, pushing blood out into the pulmonary artery and aorta.

Deviations from the normal kammioventrikulaarinen conduction can lead to various heart rhythm disorders, known as arrhythmias. These can manifest as a heart beating too fast, too slow, or irregularly. The assessment of kammioventrikulaarinen function is a key component of electrocardiography (ECG) and other cardiac diagnostic tests. Understanding this aspect of cardiac electrophysiology is vital for diagnosing and managing heart conditions.
