Epärytmi

Epärytmi is a Finnish term that translates to "arrhythmia" in English. It refers to an irregular heartbeat or an abnormal heart rhythm. This condition occurs when the electrical signals that coordinate the heart's contractions malfunction, causing the heart to beat too fast, too slow, or with an irregular pattern.

There are many types of arrhythmias, categorized by their origin in the heart's chambers and their speed. Some common examples include atrial fibrillation, where the upper chambers of the heart beat irregularly, and bradycardia, where the heart rate is too slow. Conversely, tachycardia describes a heart rate that is too fast.

The causes of epärytmi can be varied, including underlying heart conditions, such as coronary artery disease or heart failure, as well as non-cardiac factors like stress, certain medications, alcohol consumption, and electrolyte imbalances. In some cases, the cause may remain unknown.

Symptoms of epärytmi can range from unnoticeable to severe. Some individuals may experience palpitations, a fluttering or racing sensation in their chest, while others might feel dizziness, shortness of breath, chest pain, or even faint. In certain severe arrhythmias, the heart may not be able to pump blood effectively, leading to serious complications.

Diagnosis typically involves an electrocardiogram (ECG) to record the heart's electrical activity. Further tests, such as Holter monitoring or event recorders, may be used for continuous monitoring. Treatment depends on the specific type and severity of the arrhythmia and may include lifestyle modifications, medications to control heart rate or rhythm, or procedures like cardioversion or pacemaker implantation.
