How a VC Can Affect Your Heart PVCs are common and may be experienced by a wide range of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure. A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) usually controls your heart's rhythm. Electrical signals are transmitted from there to the lower chambers of your heart or ventricles. Causes PVCs are caused when the electrical impulse that typically starts your heartbeat at a point known as the sinus node (also called the sinoatrial or SA Node) doesn't. Instead, the impulse is generated in another area of your heart—the ventricles—and causes a wrongly timed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It may feel like the heart skipped a beating or feels fluttering. They can happen infrequently and have no symptoms or they may occur frequently enough to affect your quality of life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medicine. repairmywindowsanddoors are generally safe and do not increase the risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure. PVCs can trigger symptoms, such as a sensation of your heart skipping an beat, or fluttering. You may also feel exhausted. The fluttering can be more evident when you exercise or have certain foods or drinks. People with chronic anxiety or stress can have more PVCs and certain medications such as amiodarone, digoxin, and cocaine may increase the chance of developing them. If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medication. If you have frequent PVCs, your doctor might recommend avoiding certain drinks and foods, like caffeine and alcohol. You can also reduce your stress and get plenty of sleep and exercise. If you have a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. This procedure is performed by a specialist called an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms however, it doesn't prevent them from occurring in the future. In some instances, it can increase your risk of having atrial fibrillation (AFib) which can result in stroke. It is not common but it could be life-threatening. Symptoms Premature ventricular contractions, or PVCs, can make your heart appear to skip or flutter a beat. These heartbeats that are not normal can be harmless, but you might be advised to consult your physician if they are frequent or if you notice symptoms like dizziness, or fatigue. Normally, electrical signals start in the sinoatrial node located in the upper right portion of the heart. These signals move down to the lower chambers (or ventricles) that pump blood. The ventricles expand to pump blood into the lungs. They then return to the center to start the next cycle of pumping. However, a PVC starts in a different location that is separate from the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart. When PVCs occur and the heart is affected, it may feel as if it's racing or pounding. If you experience just a few episodes but no other symptoms, the doctor probably won't be able to treat you. But if you have a large number of PVCs the doctor may recommend an electrocardiogram, also known as an ECG, to measure your heart rate over 24 hours. The doctor may also suggest wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs. Anyone who has suffered an earlier heart attack or have suffered from cardiomyopathy – an illness that affects method by which the heart pumps blood – should take their PVCs very seriously and speak to a cardiologist about lifestyle modifications. Those include abstaining from alcohol, caffeine and smoking, reducing anxiety and stress, and ensuring adequate sleep. A cardiologist may also prescribe medication to slow the heartbeat, like a beta blocker. If you experience frequent PVCs, even if you don't have any other symptoms 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, when they are frequent enough, they may weaken the heart muscle. The majority of people with PVCs do not experience any problems. They just want to know that the fluttering or racing heartbeats aren't normal. Diagnosis PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience a lot of them might feel like they're going to faint. They can also happen with exercise, though many athletes who suffer from them don't have issues with their health or heart. PVCs may show up on tests such as an electrocardiogram, or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart. Often, a doctor will be able to tell whether a person has PVCs from a patient's history and physical exam. But sometimes they might not be aware of them until they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias and they might be used when there is a concern of heart disease. If your cardiologist concludes that your heart's structure is normal, reassurance will be the only treatment required. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine, and over the prescription decongestants, as well as decreasing stress can help. Getting regular exercise, staying at a healthy weight and drinking enough water can also reduce your episodes of PVCs. If your symptoms persist or extreme, consult your doctor about medication that could help reduce the symptoms. Treatment If PVCs are rare or do not cause symptoms, they don't usually require treatment. If you are frequently affected and frequently, your doctor might want to look for other heart conditions and suggest lifestyle changes or medicine. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them. If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips a beating or has additional beats. PVCs are more prevalent among people who suffer from heart issues however it's unclear what causes them. PVCs can become more frequent as you age, and they may be more frequent during exercising. A doctor should conduct an ECG along with an echocardiogram for a patient who has frequent and painful PVCs to rule out structural heart diseases. They may also perform an exercise stress test to determine whether the additional beats are a result of physical exercise. To find out whether there are other reasons for the extra beatings, a heart catheterization or an MRI is possible. The majority of people with PVCs don't experience any issues and can live an ordinary life. They can increase the risk of developing dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases, this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout the body. Regular exercise and a healthy diet can reduce your risk of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. You should also try to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you are taking any of these medicines, it is important that you follow your doctor's recommendations regarding healthy eating, exercising, and taking your medication. Studies of patients with an excessive amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to a need for a heart transplant in some patients.
