what is svt

Supraventricular tachycardia (SVT) is a type of arrhythmia characterized by an irregularly fast or erratic heartbeat that affects the hearts upper chambers. It is a condition where the heart suddenly beats much faster than normal, with a heart rate exceeding 100 beats per minute. SVT can be caused by various factors such as exercise, stress, lack of sleep, coronary artery disease, heart failure, and abnormal pathways or electrical circuits in the heart. The condition can be diagnosed through tests like an electrocardiogram (ECG) and an electrophysiology study to determine the type of SVT and its underlying cause. Treatment options for SVT include lifestyle changes, medication, and heart procedures, depending on the severity of the condition. If someone experiences symptoms such as a fast heartbeat lasting longer than 30 minutes, sudden shortness of breath with chest pain, or other concerning symptoms, immediate medical attention is necessary.
