Are PVCS caused by adrenaline?

Answer by  Moma123 (1043)

PVC is called premature ventricular contraction which is felt as palpitations in the chest. It is the irregular contraction of ventricles. Heart beats stop or become rapid and random, giving a feeling of skipped beat. Excess adrenaline can cause PVC. In normal case, adrenaline increases the heart rate.

Not usually. Pvcs are a sign of a conductivity issue in the heart and in small numbers are not that much of a problem
