How a VC Can Affect Your Heart A lot of people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure. A bundle of fibers in the top right portion of your heart (the sinoatrial or SA node) usually controls the heart's rhythm. Electrical signals travel from this node to the lower heart chambers, or ventricles. Causes PVCs occur when the electrical impulse that typically begins your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA node) isn't. The impulse actually begins in the ventricles, which causes an untimed heartbeat. These extra beats, called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat, or it feels like it is fluttering. They can occur rarely, causing no symptoms, but they can be frequent enough to impact your quality of living. If they are very frequent or cause dizziness, weakness or fatigue, your doctor could treat them with medication. In most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. Regular PVCs, however, can weaken your heart muscle over time. This is especially the case if they are caused by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure. PVCs can trigger symptoms like a feeling of your heart beating a beat, or the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more evident when you exercise or consume certain drinks or food items. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, may increase the risk of developing PVCs. If you are experiencing occasional PVCs, your doctor may suggest lifestyle changes and medications. If they're a frequent occurrence, you may have to avoid certain drinks and foods like caffeine and alcohol. You can also lower your stress by having enough sleep and exercising. If you're experiencing many PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation. It eliminates the cells that cause PVCs. This procedure is performed by a specialist known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib), which can result in stroke. It is not common, but it could be life-threatening. Signs and symptoms Premature ventricular contractions, or PVCs can cause your heart to skip or flutter. These extra heartbeats are usually harmless, however, you should talk to your doctor in case you experience frequent episodes or signs like dizziness or weakness. The electrical signals typically begin in the sinoatrial node, located in the upper right side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to propel the blood into your lungs and then return to the heart to begin the next cycle of pumping. A PVC begins at a different spot that is the Purkinje fibres bundle at the left side of the heart. When PVCs occur, they cause the heart beat faster or feel as if it skipped a beat. 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 measure the heartbeat over the course of 24 hours. He or she may also suggest wearing a Holter monitor that records your heart rhythm over time to determine how many PVCs you have. Anyone who has had a previous heart attack or suffer from cardiomyopathy -an illness that affects how the heart pumps blood — should be aware of their PVCs and talk to a cardiologist about changes to their lifestyle. Those include the avoidance of alcohol, caffeine, and smoking, reducing anxiety and stress and ensuring adequate sleep. the window doctor might also prescribe medication to slow heartbeat, for example, a beta blocker. Even if you don't have any other symptoms however, you should have PVCs examined by an expert in cardiology if they occur often. These heartbeats that are irregular can point to an issue with the structure of your heart or other health issues and, over time, when they happen frequently enough, they could 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 feel like fluttering or skipped heartbeats, especially if they are frequent or intense. People who experience them regularly might feel faint. Exercise can trigger them, but most athletes who experience them have no heart or health problems. PVCs can show up in tests like an electrocardiogram, or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart. A doctor may be able to determine if the patient has PVCs through a medical history and physical examination. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason, like following an accident or surgical procedure. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They can be used to detect heart disease in the event of any concern. If your cardiologist finds that your heart is structurally normal, reassurance is the only treatment needed. If your symptoms are bothersome, or cause you to be anxious, avoiding alcohol, caffeine, and over the drug decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms continue or are severe, speak to your doctor about treatments that could help control the symptoms. Treatment If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If they are frequent your doctor may want to check for heart problems or suggest lifestyle adjustments. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them. If you have PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can make it feel like your heart skips a beat or is beating faster. It's unclear what causes them, but they're more frequent in those with other heart problems. PVCs may increase in frequency as you age, and may be more frequent during exercising. A physician should perform an ECG along with an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. They should also conduct an exercise stress test to determine whether the extra beats are a result of physical exercise. To find out whether there are any other causes for the increased beats an invasive heart catheterization or a cardiac MRI is possible. Most people who suffer from PVCs do not experience any complications and can lead an ordinary life. They may increase your risk for heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some instances, this means that your heart muscle gets weaker and has trouble pumping blood throughout your body. A regular, healthy diet and a lot of exercise can reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. It is also important to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you take any of these medicines it is crucial that you follow the advice of your doctor regarding healthy eating exercising, as well as taking your medication. In studies of patients suffering from PVC burdens that are high (more than 20% of heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This can result in the need for a transplant in a few individuals.
