Complications
By Mayo Clinic staffComplications of tachycardias vary in severity depending on such factors as the type of tachycardia, the rate and duration of a rapid heart rate, and the existence of other heart conditions. Possible complications include:
- Blood clots that can cause a stroke or heart attack
- Inability of the heart to pump enough blood (heart failure)
- Frequent fainting spells
- Sudden death, usually only associated with ventricular tachycardia or ventricular fibrillation
