sydämensyke

Sydämensyke, also known as cardiac arrhythmia, refers to any abnormal heart rhythm. This can range from mild, such as an extra heartbeat (ectopic beat), to life-threatening, such as ventricular fibrillation, which can lead to sudden cardiac death if not treated immediately. The heart's electrical system controls its rhythm, and any disruption in this system can cause an arrhythmia.

Common types of arrhythmias include:

- Atrial fibrillation: A quivering or irregular heartbeat that can cause palpitations, shortness of breath, and an increased risk of stroke.

- Ventricular tachycardia: A fast heart rate originating below the atrium, which can lead to ventricular fibrillation if not treated.

- Bradyarrhythmias: Slow heart rates, which can be life-threatening if severe.

Risk factors for arrhythmias include coronary artery disease, high blood pressure, diabetes, and a family history of heart disease. Symptoms may include palpitations, dizziness, chest pain, shortness of breath, and fainting. Diagnosis typically involves an electrocardiogram (ECG) or an event monitor.

Treatment depends on the type and severity of the arrhythmia. Options may include lifestyle changes, medication, catheter ablation, or implantable cardioverter-defibrillator (ICD). Early detection and management are crucial, as some arrhythmias can progress to more serious conditions. Regular check-ups and a healthy lifestyle can help prevent or manage arrhythmias.
