vezetésblokk
Vezetésblokk, also known as heart block or atrioventricular block, is a condition where there is a delay or interruption in the electrical conduction between the atria and the ventricles of the heart. The heart's electrical system is responsible for coordinating the contractions of the heart chambers, ensuring blood is pumped efficiently. The atrioventricular (AV) node is a critical component of this system, acting as a gatekeeper that slows down the electrical impulse from the atria before it reaches the ventricles. Invezetésblokk, this normal slowing process is disrupted.
There are three main degrees ofvezetésblokk. First-degree AV block is characterized by a prolonged PR interval
The causes ofvezetésblokk are varied and can include age-related degeneration of the heart's electrical system, coronary
