rytmihäiriössä

Rytmihäiriö, known medically as arrhythmia, refers to an irregular heartbeat. This condition occurs when the electrical signals that coordinate the heart's contractions do not function properly, causing the heart to beat too fast, too slow, or with an irregular rhythm. While some arrhythmias are harmless, others can be serious and may lead to complications such as stroke, heart failure, or sudden cardiac arrest.

There are many different types of arrhythmias, broadly categorized as bradycardias (slow heart rates) and tachycardias (fast heart rates). Common symptoms can include palpitations, a fluttering sensation in the chest, dizziness, shortness of breath, chest pain, and fainting. However, some individuals with mild arrhythmias may experience no symptoms at all.

The causes of arrhythmias are diverse and can include underlying heart disease, such as coronary artery disease or heart valve problems, as well as non-cardiac factors like stress, caffeine, alcohol, certain medications, electrolyte imbalances, and thyroid disorders. Age and genetics can also play a role.

Diagnosis typically involves a physical examination, a review of medical history, and diagnostic tests such as an electrocardiogram (ECG or EKG), Holter monitoring, or an echocardiogram. Treatment approaches vary depending on the type and severity of the arrhythmia and may include lifestyle modifications, medications to control heart rate or rhythm, or procedures like cardioversion, pacemakers, or ablation.
