Sydänjohteluongelma

Sydänjohteluongelma refers to a disruption in the normal electrical pathway of the heart. The heart's electrical system is responsible for coordinating the contractions of its chambers, ensuring efficient blood pumping. This system involves specialized cells that generate and conduct electrical impulses. When there is a problem within this system, the impulses may be slowed, blocked, or follow an abnormal route, leading to a conduction disorder.

These disorders can manifest in various ways. Some may cause no noticeable symptoms, while others can lead to dizziness, fainting (syncope), shortness of breath, or palpitations. The severity and specific symptoms depend on the location and extent of the conduction abnormality. Common types of sydänjohteluongelma include heart blockages, where the electrical signal is partially or completely prevented from reaching certain parts of the heart, and arrhythmias, which are irregular heart rhythms resulting from faulty electrical signaling.

The causes of sydänjohteluongelma are diverse. They can be congenital, meaning present at birth, or acquired later in life. Acquired causes include underlying heart disease such as coronary artery disease, heart muscle diseases (cardiomyopathies), high blood pressure, and previous heart surgery. Age-related wear and tear on the electrical system can also contribute. Certain medications and electrolyte imbalances can also play a role. Diagnosis typically involves an electrocardiogram (ECG) to record the heart's electrical activity. Further investigations like Holter monitoring or electrophysiological studies may be required to pinpoint the exact issue. Treatment strategies vary depending on the specific condition and its severity, ranging from medication to pacemakers or even surgical interventions.
