If they occur often, PVCs may weaken your heart and increase your chance of suffering from heart failure. The rhythm of your heart is usually controlled by a bundle of fibers that are located in the upper right corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from there to the lower heart chambers or ventricles. Causes PVCs occur when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. Instead, the impulse begins in another area of your heart, the ventricles, and causes a mistimed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat, or it feels like it is like it's fluttering. They can occur infrequently and cause no symptoms, or they can occur frequently enough to impact your daily life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medication. For the majority of people, PVCs are harmless and do not increase the risk of heart disease or other health problems. Regular PVCs however, may weaken the heart muscle over time. This is particularly the case if they are caused by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure. The symptoms of PVCs include a feeling that your heart beats faster or it flutters. You may feel exhausted. The fluttering may be more apparent when you exercise, or eat or drink certain drinks or foods. People who experience chronic stress or anxiety can have more PVCs and certain medications such as amiodarone, digoxin and cocaine can increase the risk of developing them. If you experience occasional PVCs your doctor might suggest lifestyle changes and medicatio
