How a VC Can Affect Your Heart PVCs are common and may be experienced by a wide range of people without causing any issues But if they occur frequently PVCs can weaken your heart muscle and increase the risk of heart failure The hearts rhythm is usually controlled by a bundle of fibers located in the upper righthand part of your heart This is known as the sinoatrial node or SA Electrical signals are transmitted from there to the lower heart chambers or ventricles Causes PVCs are caused when the electrical impulse that usually begins your heartbeat in a part called the sinus node also called the sinoatrial or SA node doesnt Instead the impulse starts in another area of your heart called the ventricles and triggers a mistimed beat These extra beats also called ventricular tachycardia or fibrillation could feel as if your heart skipped a beat or feels like its fluttering They may happen rarely and not cause any symptoms or they can happen often enough to interfere with your daily life If they occur frequently or cause dizziness weakness or fatigue your doctor may treat them with medicine PVCs are generally harmless and dont increase your risk of developing heart disease Over time frequent PVCs can weaken the heart muscle This is especially true if they are caused by a heartrelated condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure PVCs can cause symptoms like a feeling of your heart beating an beat or the feeling of your heart fluttering It is also possible to feel breathless The fluttering can be more apparent when you exercise or have certain drinks or food items PVCs are more prevalent in people with chronic stress or anxiety Some drugs like digoxin amiodarone and cocaine can increase the risk of developing PVCs If you experience occasional PVCs your doctor may recommend lifestyle changes and medications If theyre a frequent occurrence you may need to stay clear of certain drinks and foods such as alcohol and caffeine You can also lower stress by getting enough sleep and exercising If youre experiencing lots of PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation which eliminates the 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 recurring in the future In some cases it can increase the risk of developing atrial fibrillation AFib a condition that can result in stroke Its not common but it can be lifethreatening Signs and symptoms Premature ventricular contractures or PVCs can cause your heart to skip or flutter These extra heartbeats are harmless but you might want to consult your doctor if they are frequent or if you experience symptoms such as dizziness or fatigue Normally electrical signals start at the sinoatrial junction which is in the top right side of the heart and descend to the lower chambers or ventricles that pump blood The ventricles expand to force blood into the lungs They then return to the center to begin the next cycle of pumping But a PVC begins in a different location from the bundle of fibers called the Purkinje fibers in the lower left part of the heart When PVCs occur they cause the heart beat or feel like it skipped one beat If you only have a few episodes and there are no other symptoms the cardiologist will likely not prescribe treatment If youve got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram ECG to monitor your heartbeat for 24 hours He or she may also suggest wearing a Holter monitor that will track your heart rhythm over time to determine the number of PVCs you have the glass doctor who has had a previous heart attack or suffer from cardiomyopathy a condition that affects how the heart pumps blood should be aware of their PVCs and speak with a cardiologist about lifestyle changes This includes abstaining from caffeine alcohol and smoking reducing stress and anxiety and getting enough rest A cardiologist might prescribe medication to slow heartbeat such as a beta blocker Even if you dont experience any other signs it is still recommended to have PVCs examined by a cardiologist if they happen often These extra heartbeats may indicate a problem in the structure of your lungs or heart and if they occur frequently enough can weaken your heart muscle But the majority of people with PVCs do not experience any issues They would like to know if fluttering heartbeats or skipping heartbeats is normal Diagnosis PVCs can be akin to heartbeats that flutter particularly if theyre frequent and intense People who experience them frequently may feel weak Exercise can cause them but most athletes who suffer from them do not have heart or health issues PVCs can be detected on tests such as an electrocardiogram or Holter monitor These use sticky patches with sensors that record electrical impulses from your heart A cardiologist may also use an ultrasound echocardiogram for examining the heart A doctor may be able to identify if the patient has PVCs through a medical history and physical examination However sometimes they will only be able to detect them when they examine the patient for other reasons for instance after an accident or surgery Ambulatory ECG monitoring systems can also aid in detecting PVCs and other arrhythmias and they might be used in the event of any suspicion of cardiac disease If your cardiologist concludes that your hearts structure is normal reassurance is the only treatment needed If your symptoms are bothersome or make you feel anxious avoiding alcohol caffeine and other decongestants and reducing stress can aid Engaging in regular exercise keeping at a healthy weight and drinking enough fluids can reduce your episodes of PVCs If your symptoms persist or are extreme talk with your physician about possible medications that can control these symptoms Treatment If PVCs do not cause any symptoms or happen rarely they usually dont need treatment If you experience them frequently or frequently your doctor may wish to look for other heart conditions and suggest lifestyle changes or medication You may also undergo an operation to rid yourself of them called radiofrequency catheter ablation If you suffer from PVCs in your heart the electrical signal which causes your heartbeat begins somewhere different than the sinoatrial SA node located in the upper right corner of your heart This can make it feel like your heart skips beats or has extra beats Its not known what causes them but theyre more common in people who have other heart conditions PVCs are more frequent as we age and can occur more frequently during exercising If a patient has frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to rule out structural heart disease They will probably also do an exercise stress test to see whether the additional beats are due to physical activity A heart catheterization cardiac MRI or nuclear perfusion study can be performed to find other causes for the increased beats Most people with PVCs do not suffer from any complications and can lead a normal lifestyle They can increase your risk for heart rhythm disorders that can be dangerous especially if they occur in certain patterns In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body A healthy regular diet and plenty of exercise can help reduce your chances of developing PVCs Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco Sleep and stress are equally crucial Some medicines may also increase the risk of developing PVCs If you are taking one of these drugs its important to follow your doctors instructions regarding eating healthy exercising and taking your medication In studies of patients suffering from PVC burdens that are excessive more than 20 of heartbeats there was a higher incidence of arrhythmiainduced cardiac myopathy was found This can result in the need for a transplant in certain people
