johtumishäiriö

Johtumishäiriö is a Finnish term that translates to "conduction disorder" or "conduction disturbance" in English. It refers to a disruption in the normal electrical signaling within the heart. The heart's electrical system is responsible for coordinating the rhythmic contractions of the atria and ventricles, ensuring that blood is pumped efficiently throughout the body. When this system is not functioning correctly, it can lead to various problems with heart rate and rhythm.

These disturbances can arise from issues with the sinoatrial node, the heart's natural pacemaker, or with the pathways that conduct electrical impulses from the atria to the ventricles, such as the atrioventricular node and the bundle of His. Causes of johtumishäiriö can include congenital heart defects, damage from a heart attack, aging, certain medications, electrolyte imbalances, and other underlying heart conditions.

Symptoms can vary widely depending on the severity and type of conduction disorder. Some individuals may experience no symptoms, while others might notice palpitations, dizziness, fainting (syncope), shortness of breath, or chest pain. A diagnosis typically involves an electrocardiogram (ECG) or Holter monitor to record the heart's electrical activity. Treatment strategies are tailored to the specific condition and may involve medications to regulate heart rate, lifestyle modifications, or the implantation of a pacemaker to help maintain a regular heartbeat.
