How a VC Can Affect Your Heart PVCs are common and may be experienced by a variety of people with no cause for concern. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure. A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial, or SA, node) typically controls your heart rhythm. Electrical signals are transmitted to the ventricles or lower chambers of your heart. Causes PVCs are caused when the electrical impulse that usually begins your heartbeat in a region known as the sinus node (also known as the sinoatrial node or SA node) doesn't. Instead, the impulse begins in another area of your heart, the ventricles, and causes a mistimed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat or feels fluttering. They may happen rarely and cause no symptoms, or they may occur frequently enough to impact your daily life. Your doctor may prescribe medicine in the event that they are frequent or cause weakness, dizziness or fatigue. In most people, PVCs are harmless and don't increase your risk of heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure. PVCs can cause symptoms like a feeling of your heart skipping an beat, or fluttering. windows doctor is also possible to feel breathless. The fluttering may be more noticeable when you exercise or eat or drink certain drinks or foods. People who experience chronic anxiety or stress can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine can increase the chance of developing them. If you experience occasional PVCs your doctor may recommend lifestyle changes and medication. If you experience frequent PVCs, your doctor may suggest that you stay away from certain drinks and foods, such as caffeine and alcohol. You can also take steps to lessen your stress, and take advantage of plenty of rest and exercise. If you're experiencing a lot of PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. This procedure is performed by a specialist, known as an electrophysiologist. The treatment is generally effective in treating PVCs, reducing symptoms but does not prevent them from returning 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 make your heart appear to flutter or skip one beat. These extra heartbeats are generally harmless, but it is important to consult your physician if you have frequent episodes or signs like dizziness or weakness. Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles contract to push the blood into the lungs. They then return to the center to begin the next cycle of pumping. However, 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 can make the heart appear to be beating faster or slower. If you have a few episodes and no other symptoms, your doctor will probably not treat you. If you've got a lot of PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. The doctor may also recommend wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs. If you've had a previous heart attack or cardiomyopathy - an illness that affects method by which the heart pumps blood - must take their PVCs seriously and speak to a cardiologist regarding lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might also prescribe medication to slow heartbeat, like beta blockers. Even if you don't experience any other indications, you should still get PVCs checked by an cardiologist if they occur frequently. These extra heartbeats can indicate a problem with the structure of your heart or 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 are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal. Diagnosis PVCs can appear to be fluttering or skip heartbeats, especially if they're frequent or intense. People who experience them frequently might feel faint. Exercise can cause PVCs, but a lot of athletes who experience them have no heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist may also use an ultrasound echocardiogram to study the heart. A doctor will usually be able to determine if a patient has PVCs by looking at them and taking a medical history. Sometimes, they may only notice them while examining the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They are able to identify cardiac problems when there is a reason to be concerned. If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine, and over the counter decongestants, and reducing stress may aid. Regular exercise, being at a healthy weight and drinking enough water can help reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your physician about the medications that could help reduce these symptoms. Treatment If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If they occur frequently, your doctor might need to examine for heart conditions or recommend lifestyle modifications. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation). If you have PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease however it's unclear the reason behind them. PVCs may increase in frequency as you age, and they could be more frequent during exercising. A doctor should conduct an ECG and an echocardiogram on a patient who suffers from frequent and painful PVCs to rule out structural heart diseases. They should also conduct an exercise stress test to determine whether the extra beats are due to physical activity. To find out if there are other causes for the extra beats the heart catheterization or cardiac MRI is possible. Most people who suffer from PVCs do not experience any issues and can live 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 instances, this means the heart muscle gets weaker and is having difficulty pumping blood throughout your body. Regular exercise and a balanced diet can reduce your risk of developing PVCs. You should avoid foods that are high in fat and sodium and restrict your intake of tobacco and caffeine. It is also important to get enough rest and reduce stress. Certain medicines can also increase your risk for PVCs. So if you take one of these medications it is important to follow the doctor's advice about eating well, 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 arrhythmia-induced cardiac myopathy was discovered. Certain people may require a heart transplant.
