How a VC Can Affect Your Heart Many people experience occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase the risk of heart failure. A bundle of fibers located in the upper right part of your heart (the sinoatrial, or SA, node) usually controls your heart's rhythm. Electrical signals travel from this node to the lower heart chambers or ventricles. Causes PVCs occur when the electrical impulse that usually starts your heartbeat in a part called the sinus node (also called the sinoatrial or SA Node) isn't. Instead, the impulse starts in a different area of your heart called the ventricles and triggers a wrongly timed beat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart skipped a beating or feels like it is fluttering. They can occur infrequently and not cause any symptoms, or they may occur frequently enough to interfere with your daily life. Your doctor might prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue. PVCs are generally harmless and do not increase the risk of heart disease. Regular PVCs however, could weaken the heart muscle over time. This is particularly relevant if the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure. The symptoms of PVCs include a feeling that your heart beats slower or it flutters. You may feel exhausted. The fluttering can be more apparent if you exercise, or eat or drink certain foods or beverages. PVCs are more common for those who suffer from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone and cocaine, can also increase the risk of developing PVCs. If you have occasional PVCs your doctor may recommend lifestyle changes and medication. If they are a frequent occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. window doctor can also take steps to lessen your stress levels, and take advantage of plenty of rest and exercise. If you've got a lot of PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In some cases it can increase the risk of atrial fibrillation (AFib), a condition that can cause stroke. It is not common, but it could be life-threatening. Symptoms Premature ventricular contractions or PVCs, can cause your heart appear to flutter or skip one beat. These extra heartbeats can be harmless, but you might need to see your doctor in the event of frequent heartbeats or if you are experiencing symptoms like dizziness or fatigue. The electrical signals typically begin at the sinoatrial junction, which is in the top right-hand side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles contract to force blood into the lungs. They then return to the center to begin the next cycle of pumping. A PVC starts in a different location, the Purkinje fibres bundle in the bottom left of the heart. When PVCs occur, they can make the heart beat or feel as if it skipped the beat. If you've experienced just a few episodes but no other symptoms, your cardiologist probably won't treat you. If you've got a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. They may also suggest wearing a Holter monitor that will track the heart's rhythm over time to determine how many PVCs you have. Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -which alters the way the heart pumps blood must be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. These include avoiding alcohol, caffeine and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat. If you experience frequent PVCs, even if you do not have other signs, you should see a cardiologist. These heartbeats that are irregular can be a sign of a problem with the structure of your heart or to other health conditions and, over time if they occur often enough, they may weaken the heart muscle. Most people with PVCs don't experience any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal. Diagnosis PVCs might appear to be fluttering or skip heartbeats, especially when they're frequent or intense. People who experience a lot of them might feel like they're about to faint. They can also occur during training, even though many athletes who get them do not have any issues with their health or heart. PVCs may show up in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart. A doctor will usually be able to determine whether a patient has PVCs by examining them and taking their medical history. Sometimes, however, they may not be aware of PVCs until they examine the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They may be used to detect cardiac disease when there is a concern. If your cardiologist determines that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are causing discomfort or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your doctor about medication that could be able to control the symptoms. Treatment If PVCs aren't causing symptoms or occur rarely, they usually don't need treatment. If they are frequent, your doctor might need to examine for heart issues or suggest lifestyle changes. You could also have an operation (called radiofrequency cathode ablation) to eliminate of them. If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or is beating faster. They're more common among people suffering from heart disease however it's unclear the reason behind them. PVCs can become more frequent as you age, and they may be more frequent during exercise. A doctor should perform an ECG and an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also perform an exercise stress test in order to determine if the extra heartbeats are related to physical activity. To find out whether there are any other causes for the extra beatings the heart catheterization or an MRI is possible. The majority of people who suffer from PVCs do not experience any problems and can enjoy an ordinary life. But they can increase your risk of having dangerous heart rhythm problems, especially if you have certain patterns of them. In some instances, this means that your heart muscle gets weaker and is having difficulty pumping blood throughout your body. A healthy and balanced diet and regular exercise can reduce the chances of developing PVCs. Avoid foods that are high in sodium and fat, and limit your consumption of tobacco and caffeine. Sleep and stress are equally important. Certain medications can increase the risk of developing PVCs. If you are taking one of these drugs it is important to follow your doctor's recommendations about eating well, exercising and taking your medication. Studies of patients suffering from a high burden of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can result in a need for a heart transplant in some individuals.
