supraventiikulaarinen

Supraventikulaarinen refers to something located above the ventricles of the heart. In a medical context, it most commonly describes arrhythmias, which are abnormal heart rhythms originating from electrical activity above the ventricles. These supraventricular arrhythmias can arise from the atria, the atrioventricular (AV) node, or the junctional tissue connecting the atria and ventricles.

Common types of supraventricular arrhythmias include atrial fibrillation, atrial flutter, and supraventricular tachycardia (SVT). SVT is a broad category that encompasses several rapid heart rhythms originating above the ventricles. Symptoms of supraventricular arrhythmias can vary but often include palpitations, dizziness, shortness of breath, chest pain, and fainting. The underlying causes are diverse and can include structural heart disease, electrolyte imbalances, hormonal conditions, and certain medications.

Diagnosis typically involves an electrocardiogram (ECG) to record the heart's electrical activity. Holter monitors or event recorders may be used for intermittent arrhythmias. Treatment strategies depend on the specific type of supraventricular arrhythmia, its severity, and the patient's overall health. Options can range from lifestyle modifications and medications to electrical cardioversion or catheter ablation procedures. Understanding the location of origin, above the ventricles, is crucial for accurate diagnosis and effective management.
