Is pain in the carotid artery a sign of heart failure with frequent pvc's, faintness, fast heart rate and bloating?

Carotid artery: disease in itself has no symptoms; it causes symptoms when blood flow to the brain is decreased because of it. Perhaps you are having neck pain, near the location of the carotid artery, but I would not interpret that as a sign of heart failure or cause of PVC's. Certainly frequent PVC's might be a sign of more serious dysrhythmia causing faintness/fast heart rate. You need to continue cardiac care
