ComplicationsBy Mayo Clinic Staff
If you have frequent premature ventricular contractions or certain patterns of premature ventricular contractions, you may be at increased risk of developing heart rhythm problems (arrhythmias) or weakening of the heart muscle (cardiomyopathy).
Rarely, when accompanied by underlying heart disease, frequent premature contractions can lead to chaotic, dangerous heart rhythms and possibly sudden cardiac death.
