How a VC Can Affect Your Heart PVCs are commonplace and can be experienced by a wide range of people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure. The heart's rhythm is controlled by a bundle of nerve fibers situated in the upper right corner of your heart. This is known as the sinoatrial node or SA. Electrical signals travel to ventricles, or lower chambers of the heart. Causes PVCs happen when the electrical impulse that usually starts your heartbeat in a region called the sinus node (also called the sinoatrial or SA node) does not. The impulse actually begins in the ventricles and causes an irregular heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart beats faster or feels like it is fluttering. They may occur infrequently, causing no symptoms, but they could be frequent enough to affect your quality of life. Your doctor may prescribe medication if they are frequent or cause weakness, dizziness or fatigue. PVCs are generally harmless and don't increase your risk of heart disease. Frequent PVCs, however, can weaken the heart muscle over time. This is especially when the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure. PVCs can cause symptoms, such as a sensation of your heart beating an beat, or the feeling of your heart fluttering. It is also possible to feel breathless. The fluttering can be more evident when you exercise or have certain drinks or foods. People who suffer from chronic stress or anxiety can have more PVCs, and some drugs like amiodarone digoxin, and cocaine may increase the likelihood of developing them. If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor may recommend that you avoid certain foods and drinks such as caffeine and alcohol. You can also lower your stress levels by having enough sleep and exercising. If you've got a lot of PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. It is generally effective in treating PVCs and reducing symptoms but it doesn't stop them from recurring in the future. In some instances, it can increase your risk of having atrial fibrillation (AFib), which can lead to a stroke. It is not common, but it can be life-threatening. Symptoms Premature ventricular contractions, also known as PVCs, may make your heart appear to flutter or skip one beat. These extra heartbeats are usually harmless, however, you should consult your physician when you experience frequent episodes or signs like dizziness or weakness. Normaly, electrical signals begin in the sinoatrial, located in the upper right part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles then expand to push blood into your lungs, and then return to your heart and start the next pumping cycle. However, a PVC begins at a different spot, from the bundle of fibers called the Purkinje fibers, located in the left-hand side of the heart. When PVCs happen, the heart may feel as if it's racing or pounding. If you experience only a few episodes, and no other symptoms are present, your cardiologist will probably not treat you. If you've got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. They might also recommend wearing a Holter monitor that will track your heart rhythm over time, allowing you to see how many PVCs you have. If you've had previously from a heart attack or cardiomyopathy – an illness that affects the heart's blood flow – should take their PVCs seriously and speak to an expert in cardiology about lifestyle modifications. These include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and getting enough rest. A cardiologist might prescribe medication to slow the heartbeat for example, beta blockers. Even if you don't have any other symptoms however, you should have PVCs checked by an cardiologist if they occur often. These heartbeats that are irregular can indicate problems with the structure of your heart or to other health conditions and, over time if they occur often enough, they could weaken the heart muscle. Most people who suffer from PVCs don't experience any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal. Diagnosis PVCs might be felt as fluttering or skipped heartbeats, especially when they are frequent or intense. Patients who have a lot of them may feel they're about to faint. They can also occur with exercise, though many athletes who experience them don't have any problems with their heart or health. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to examine the heart and see how it's working. A doctor may be able to identify if a person is suffering from PVCs from a history and physical examination. Sometimes it is possible that they only notice PVCs when examining patients for a different reason such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They are able to detect cardiac disease if there is any reason to be concerned. If your cardiologist finds that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are troubling, or cause you to feel anxious, staying away from alcohol, caffeine and other over the drug decongestants and reducing stress may aid. Engaging in regular exercise, keeping 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 control the symptoms. Treatment If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If double glazing doctor repairmywindowsanddoors occur frequently your doctor may need to examine for heart problems or suggest lifestyle changes. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate of them. If you have PVCs in your heart the electrical signal that 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 could cause your heart to feel as if it skips a beating or has additional beats. It's not clear what causes them, but they're more frequent in those with other heart issues. PVCs can increase in frequency with age and might happen more often during exercises. If a patient is experiencing frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor may also conduct an exercise stress test to determine if the additional heartbeats are due to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be conducted to determine other causes for the additional beats. Most people who suffer from PVCs don't experience any problems and can enjoy an ordinary life. However, they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some cases, this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout the body. A healthy, regular diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. Stress and sleep are also crucial. Some medicines may also increase the risk of developing PVCs. If you're taking one of these drugs, it's important to follow your doctor's instructions about eating well, exercising and taking your medication. In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats), a higher rate arrhythmia-induced cardiac myopathy was discovered. This can lead to the need for a transplant in a few individuals.
