How a VC Can Affect Your Heart Many people experience occasional PVCs with no problems However if they happen frequently PVCs can weaken your heart muscle and increase your risk of heart failure A bundle of fibers in the top right portion of your heart the sinoatrial or SA node typically regulates the hearts rhythm Electrical signals are transmitted to the ventricles or lower chambers of the heart Causes PVCs occur when the electrical impulse that normally initiates your heartbeat in a region called the sinus node also called the sinoatrial or SA Node does not Instead the window doctor starts in a different part of your heart the ventricles and causes an untimed beat These extra beats are known as ventricular tachycardia and ventricular fibrillation It could feel as if the heart skipped a beat or feels fluttering They can occur rarely without causing any symptoms but they could also happen frequently enough to affect your standard of living If they are very frequent or cause dizziness weakness or fatigue your doctor could treat them with medication PVCs are generally safe and do not increase your risk of heart disease In time frequent PVCs can weaken the heart muscle This is particularly relevant if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure The signs of PVCs include a feeling that 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 foods People who suffer from chronic anxiety or stress can have more PVCs and some medications like amiodarone digoxin and cocaine can increase the chance of developing them If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication If they are a frequent occurrence you may need to avoid certain drinks and foods such as alcohol and caffeine You can also take steps to reduce your stress levels and get plenty of sleep and exercise If youve got a lot of PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation It eliminates the cells responsible for them This procedure is performed by a specialist known as an electrophysiologist The treatment is usually successful in treating PVCs and reducing symptoms but it does not stop them from returning in the future In some instances it can increase your risk of having atrial fibrillation AFib which can result in a stroke It is not common however it could be lifethreatening Signs and symptoms Premature ventricular contracts or PVCs may cause your heart to skip or flutter These heartbeats can be harmless but it is important to talk to your doctor when you experience frequent episodes or signs like dizziness or weakness Normally electrical signals begin in the sinoatrial node located in the top right portion of the heart and travel down to the lower chambers or ventricles that pump blood Then the ventricles expand to push blood into the lungs and return to the heart to start the next pumping cycle But a PVC begins in a different location from the bundle of fibers known as the Purkinje fibers located in the bottom left portion of the heart When PVCs occur they make the heart pound or feel as if it skipped a beat If you only have one or two episodes and there are no other symptoms the cardiologist will likely not prescribe treatment But if you have a number of PVCs the doctor may recommend an electrocardiogram also known as an ECG to measure your heart rate over the course of 24 hours He or she may also suggest wearing a Holter monitor which will record your heartbeat over time allowing you to see how many PVCs you have People who have had a prior heart attack or suffer from cardiomyopathy a condition that affects how the heart pumps bloodand must be aware of their PVCs and speak with a cardiologist about lifestyle changes Those include the avoidance of alcohol caffeine and smoking managing stress and anxiety and getting enough rest A cardiologist can prescribe beta blockers to slow the heartbeat If you experience frequent PVCs even if dont have any other symptoms you should see a cardiologist These extra heartbeats can indicate problems with the structure of your heart or to other health conditions and over time when they happen frequently enough they can weaken the heart muscle But the majority of people suffering from PVCs do not experience any issues They would like to know if irregular heartbeats or fluttering is normal Diagnosis PVCs can be akin to heartbeats that are fluttering especially if they are frequent and intense Patients who have a lot of them may feel theyre going to faint Exercise can trigger PVCs but a lot of athletes who experience them have no heart or health problems PVCs may show up in tests such as an electrocardiogram ECG or Holter monitor They have sensors that record electrical impulses coming from your heart A cardiologist could also employ an ultrasound echocardiogram to examine the heart A doctor may be able to identify if someone has PVCs from a patients history and physical exam Sometimes however they may only notice PVCs when examining a patient for another reason such as after an accident or surgery Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias They are able to detect cardiac disease in the event of any concerns If your cardiologist determines that your heart is structurally normal reassurance is the only treatment required If your symptoms are causing you discomfort or make you feel anxious staying away from alcohol caffeine and other over the prescription decongestants as well as the reduction of stress could aid Regular exercise maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs If your symptoms persist or severe speak to your doctor about medication that could help reduce them Treatment If PVCs are rare or dont cause symptoms they rarely require treatment If they are frequent your doctor might want to check for heart conditions or recommend lifestyle modifications You may also undergo a procedure called radiofrequency cathode ablation to get rid them If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial SA node which is located in the upper right corner of your heart This could cause it to feel like your heart skips a beat or has extra beats Theyre more common among people with heart problems but its not known what causes them PVCs can increase in frequency as you age and may occur more frequently during exercises If a patient has frequent and painful PVCs a physician should perform an ECG and an echocardiogram to rule out structural heart disease They will probably also do an exercise stress test to see if the extra beats are due to physical exercise A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for other causes of the extra beats The majority of people with PVCs do not experience any problems and can enjoy an ordinary life But they can increase the risk of developing dangerous heart rhythm problems especially if you are suffering from certain patterns of them In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout your body A healthy regular diet and a lot of exercise can reduce the risk of developing PVCs Avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco Stress and sleep are also crucial Certain medicines can also increase your risk of getting PVCs If youre taking one of these medications its crucial to follow your doctors recommendations regarding eating healthy exercising and taking your medication In studies of patients suffering from PVC burdens that are high more than 20 of heartbeats the higher rate of arrhythmiainduced cardiac myopathy was found This could lead to the need for a heart transplant in some people
