Supraventricular Tachycardia (SVT) Symptoms
Supraventrical Tachycardia (SVT) Symptoms
Supraventricular tachycardias (SVTs) are usually 150-250 beats per minute but can be both slower or faster. Commonly, supraventricular tachycardia results in symptoms such as rapid heart beating, dizziness, shortness of breath, or chest discomfort.
SVTs are not felt to be life-threatening themselves. Patients with SVTs may have a wide range of symptoms. Particularly when SVTs are brief or not too rapid patients may not be aware that they have an SVT. Most commonly patients describe a rapid heart sensation, often as if their hearts are pounding out of their chests. Patients also describe shortness of breath, chest discomfort, or dizziness or lightheadedness.
For many patients, most or all episodes of SVT stop on their own. The duration ranges widely from seconds to minutes and occasionally hours.
