How a VC Can Affect Your Heart
A lot of people experience occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase your risk of heart failure.
A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial or SA node) typically controls your heart's rhythm. Electrical signals are transmitted to the lower heart chambers or ventricles.
Causes
PVCs are caused by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat or is fluttering. They can occur rarely and not cause any symptoms, but they can be frequent enough to impact your quality of life. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor may treat them with medication.
PVCs are generally harmless and do not increase the risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is particularly the case if they are caused by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.
The symptoms of PVCs include feeling like your heart beats slower or it flutters. You may feel breathless. The fluttering can be more evident when you exercise or have certain drinks or food items. PVCs are more common in those suffering from chronic anxiety or stress. Some medications, such as digoxin, amiodarone, and cocaine, may increase their risk.
If you experience occasional PVCs your doctor may suggest lifestyle changes and medications. If they're a frequent occurrence, you may have to avoid certain foods and beverages, such as caffeine and alcohol. You can also lessen your stress by getting enough sleep and exercising.
If you have many PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation, which destroys cells that cause PVCs. This procedure is performed by a specialist, known as an electrophysiologist. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from returning in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), which can result in stroke. This is rare but can be life-threatening.
