Is supraventricular tachycardia serious?
Supraventricular tachycardia can vary in severity. This depends on the rate and duration of a rapid heart rate and whether you have other heart conditions. Some possible complications may include: the formation of blood clots that can cause a stroke or heart attack; the inability of your heart to pump enough blood (heart failure), and; sudden death - some of the less common forms of supraventricular tachycardia can transform into very unstable heart rhythms.
