How a VC Can Affect Your Heart PVCs are common and can be experienced by a wide range of people with no cause for concern But if they occur frequently PVCs can weaken your heart muscle and increase the risk of heart failure The rhythm of your heart is usually controlled by a bundle of fibers located in the upper righthand part of your heart This is known as the sinoatrial nerve or SA Electrical signals travel to the ventricles or lower chambers of the heart Causes PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node also called the Sinoatrial or SA node is not initiated Instead the impulse starts in a different area of your heart the ventricles and causes a wrongly timed beat These extra beats also known as ventricular tachycardia or ventricular fibrillation can feel like your heart skipped a beat or it feels like it is like it is fluttering They may happen rarely and cause no symptoms or they can occur frequently enough to interfere with your quality of life If they occur frequently or cause weakness dizziness or fatigue your doctor could treat them with medicine For most people PVCs are harmless and dont increase your risk of heart disease or other health issues In time repeated PVCs can weaken the heart muscle This is especially relevant if the PVCs are caused by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure The signs of PVCs include feeling like your heart beats slower or flutters and you may feel breathless The fluttering can be more apparent when you exercise or have certain drinks or food items PVCs are more common in people with chronic anxiety or stress Certain medications such as digoxin amiodarone and cocaine can also increase the risk If window doctors have occasional PVCs your doctor may suggest lifestyle changes and medication If you are prone to frequent PVCs your physician may suggest that you stay away from certain foods and drinks like caffeine and alcohol You can also lower your stress levels by getting enough sleep and exercising If youve got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation This procedure destroys the cells that cause them Electrophysiologists are the ones who perform this procedure The treatment is typically effective in treating PVCs which reduce symptoms but does not prevent them from recurring in the future In certain cases it can increase your risk of atrial fibrillation AFib which can lead to stroke It is not common but it could be lifethreatening Symptoms Premature ventricular contractures or PVCs can cause your heart to skip or flutter These heartbeats that are not normal can be harmless but you may need to see your doctor when they occur frequently or if you are experiencing symptoms like dizziness or fatigue Normally electrical signals begin at the sinoatrial junction located in the upper right portion of the heart and move down to the lower chambers or ventricles which pump blood The ventricles contract to propel the blood into your lungs and return to the heart and start the next pumping cycle But a PVC begins in a different location that is separate from the bundle of fibers known as the Purkinje fibers in the lower left part of the heart When PVCs occur they cause the heart beat or feel as if it skipped a beat If youve experienced just a few episodes but no other symptoms your doctor probably wont be able to treat you If you have a lot of PVCs the doctor may suggest that you undergo an electrocardiogram ECG to determine the heartbeat for 24 hours The doctor might also recommend wearing a Holter monitor that records the hearts rhythm over time allowing you to see the number of PVCs you have People who have had a prior heart attack or have cardiomyopathy which affects the way that the heart pumps blood should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes This includes abstaining from alcohol caffeine and smoking managing anxiety and stress and getting enough sleep A cardiologist can prescribe beta blockers to slow the heartbeat Even if there arent any other signs however you should have PVCs examined by an expert in cardiology if they occur frequently These extra heartbeats may signal a problem with the structure of your heart or lungs and if they occur frequently enough they can weaken the heart muscle But the majority of people suffering from PVCs dont experience any problems They want to know if the irregular heartbeats or fluttering is normal Diagnosis PVCs may feel like heartbeats that are fluttering particularly if theyre frequent and intense Patients who have a lot of them might feel like theyre going to faint They can also occur with exercising but most athletes who experience them do not have any issues with their health or heart PVCs could show up in tests like an electrocardiogram ECG or Holter monitor They have sensors that record electrical impulses coming from your heart A cardiologist could also employ an echocardiogram which makes use of ultrasound to examine the heart and observe how its working Often a doctor will be able to tell whether a person is suffering from PVCs from a patients history and physical examination Sometimes however they might only be able to detect PVCs when they examine the patient for another reason such as following an accident or surgical procedure 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 a cardiac condition If your cardiologist finds that your hearts structure is normal reassurance is the only treatment needed If your symptoms are bothersome or make you feel anxious staying away from alcohol caffeine and overthe prescription decongestants as well as reducing stress may help Getting regular exercise staying at a healthy weight and drinking enough water can also help reduce the frequency of PVCs If your symptoms continue or are severe speak to your doctor about possible treatments that could help control the symptoms Treatment If PVCs dont cause symptoms or are not frequent they usually dont need treatment If they occur frequently your doctor may need to examine for heart problems or suggest lifestyle modifications You could also undergo a procedure called radiofrequency cathode ablation to get rid them If you suffer from PVCs in your heart the electrical signal that causes your heartbeat begins somewhere outside of the sinoatrial SA node that is located in the upper righthand corner of your heart This can make it feel like your heart skips beats or is beating faster Its not clear what causes these symptoms but theyre frequent in those with other heart conditions PVCs are more likely to occur as you age and may be more frequent during exercising A doctor should conduct an ECG along with an echocardiogram on a patient who suffers from frequent and painful PVCs to rule out structural heart diseases They may also perform an exercise stress test to see whether the additional beats are due to physical exercise A heart catheterization or cardiac MRI or nuclear perfusion study could be performed to find other reasons for the additional beats The majority of people who suffer from PVCs do not suffer from any problems and can enjoy an ordinary life They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout your body Regular exercise and a balanced diet will lower the risk of developing PVCs Avoid foods high in fat and sodium and limit your intake of tobacco and caffeine Sleep and stress are also important Some medicines may also increase your risk for PVCs If you take any of these medications it is important to follow the advice of your doctor regarding eating a healthy diet exercising and taking your medication Studies of patients suffering from a high burden of PVCs thats more than 20 percent of their total heart beats discovered that they had a higher incidence of arrhythmiainduced cardiomyopathy This can lead to the need for a transplant in a few individuals
