How a VC Can Affect Your Heart A lot of people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure. The heart's rhythm is usually controlled by a bundle of nerve fibers situated in the upper right part of your heart. This is called the sinoatrial node, or SA. Electrical signals travel to ventricles or lower chambers of your heart. Causes PVCs are caused when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. Instead, the impulse begins in a different part of your heart, the ventricles, and causes a wrongly timed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. They may feel like the heart beats faster or feels 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. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue. For the majority of people, PVCs are harmless and don't increase your risk of heart disease or other health issues. A lot of PVCs, however, can weaken the heart muscle over time. This is especially relevant if the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure. PVCs can trigger symptoms, such as a sensation of your heart beating one beat, or even fluttering. It is also possible to feel breathless. The fluttering could be more noticeable when you exercise or eat or drink certain drinks or foods. People who experience chronic anxiety or stress may have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the likelihood of developing them. If you have occasional PVCs your doctor might suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor may recommend that you avoid certain foods and drinks such as caffeine and alcohol. You can also take steps to reduce your stress, and make sure you get enough sleep and exercise. If you're experiencing lots of PVCs, he may suggest a medical treatment called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. The procedure is carried out by a specialist, known as an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In certain cases it may increase the risk of developing atrial fibrillation (AFib) which could lead to a stroke. This is rare however it could be life-threatening. Symptoms Premature ventricular contractions, or PVCs can cause your heart to skip or flutter. These extra heartbeats are generally harmless, but it is important to consult your physician in case you experience frequent episodes or signs like dizziness or weakness. Normally, electrical signals begin in the sinoatrial node which is in the top right-hand side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles expand to push blood into your lungs and return to the heart and start the next cycle of pumping. However, a PVC begins in a different place that is separate from the bundle of fibers, known as the Purkinje fibers in the left-hand side of the heart. When PVCs occur they can make the heart feel as if it's beating faster or slower. If you experience just a few episodes but no other symptoms, your doctor will probably not treat you. If you have a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. They may also suggest wearing a Holter monitor that records your heart rhythm over time to see the number of PVCs you have. If you've had previously from a heart attack or have suffered from cardiomyopathy – an illness that affects way the heart pumps blood – should take their PVCs very seriously and consult a cardiologist regarding lifestyle modifications. Those include abstaining from alcohol, caffeine and smoking, managing stress and anxiety and getting enough sleep. A cardiologist might prescribe medication to slow heartbeat, such as a beta blocker. Even if you don't have any other symptoms, you should still get PVCs checked by a cardiologist if they happen frequently. These irregular heartbeats could indicate problems with the structure of your heart or to other health conditions and, over time when they are frequent enough, they can weaken the heart muscle. Most people who suffer from PVCs don't experience any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal. Diagnosis PVCs may be felt as fluttering or skipped heartbeats, especially if they're frequent or intense. People who experience them regularly might feel faint. They can also happen with exercise, though many athletes who experience them don't have any problems with their heart or health. PVCs can be detected in tests like an electrocardiogram or a Holter monitor. These use sticky patches with sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and see how it's working. A doctor may be able to determine if the patient has PVCs through a medical history and physical examination. But sometimes they might only be able to detect them when they examine the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to identify cardiac problems when there is a concerns. If your cardiologist has determined that your heart is structurally healthy, reassurance may be all you need. However, if your symptoms are causing discomfort or make you feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms continue or are extreme, talk to your doctor about possible treatments that could help control them. Treatment If PVCs aren't common or don't cause symptoms, they don't usually require treatment. If they happen frequently, your doctor might want to check for heart conditions or recommend lifestyle modifications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation). If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located different than the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips beats or has additional beats. It's not known what causes them, but they're more frequent in those with other heart problems. PVCs are more likely to occur as you age, and they may be more frequent during exercising. A physician should perform an ECG along with an echocardiogram on a patient that suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor may also conduct an exercise stress test to determine if the increased heartbeats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for other reasons for the increased beats. Most people with PVCs do not suffer from any issues and can live a normal lifestyle. They may increase your risk for heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases, that means that your heart muscle gets weaker and has trouble pumping blood through your body. A healthy and balanced diet and plenty of exercise can reduce your risk of developing PVCs. You should avoid foods that are high in fat and sodium, and you should also limit caffeine and tobacco. Also, you should try to get enough rest and manage stress. repairmywindowsanddoors can increase the risk of developing PVCs. If you are taking any of these medicines, it is important to follow your doctor's advice regarding healthy eating and exercising as well as taking your medication. Studies of patients suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require a heart transplant.
