The medical abbreviation "SVT" stands for "Supraventricular Tachycardia".
SVT is a type of abnormal heart rhythm or arrhythmia, characterized by rapid and regular heartbeats originating from above the ventricles of the heart. The normal resting heart rate for adults is typically between 60 and 100 beats per minute, while in SVT, the heart rate may exceed 150 beats per minute. This can cause symptoms such as palpitations, chest discomfort, lightheadedness, and shortness of breath.
SVT can occur in people of any age, and may be triggered by various factors, such as stress, caffeine, alcohol, or certain medications. In some cases, the cause of SVT is unknown.
Treatment of SVT depends on the severity of symptoms and the frequency of episodes. Mild cases may not require treatment, while more severe or frequent episodes may require medication or medical procedures such as cardioversion, catheter ablation, or surgery.
