How a VC Can Affect Your Heart Many people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure. The heart's rhythm is usually controlled by a group of fibers located in the upper right-hand part of your heart. This is known as the sinoatrial node or SA. Electrical signals are transmitted from there to the lower heart chambers or ventricles. Causes PVCs occur when the electrical impulse that typically begins your heartbeat in a region called the sinus node (also known as the sinoatrial node or SA node) isn't. Instead, the impulse is generated in a different part of your heart called the ventricles and triggers an untimed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat, or it feels like it is fluttering. They can occur infrequently and have no symptoms or they can happen often enough to interfere with your daily life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor might treat them with medication. PVCs are generally harmless and do not increase the risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is particularly when the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure. PVCs can trigger symptoms, such as a sensation of your heart beating a beat, or fluttering. You may also feel exhausted. The fluttering can be more noticeable if you exercise, or consume certain beverages or foods. PVCs are more prevalent in those suffering from chronic anxiety or stress. Some medications, such as digoxin, amiodarone, and cocaine, can also increase the risk. If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your physician may suggest that you stay away from certain drinks and foods, like caffeine and alcohol. You can also lower your stress levels by having enough sleep and exercising. If double glazing doctor experiencing many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. Electrophysiologists are the ones who execute this procedure. It is generally successful in treating the PVCs and reducing symptoms however it does not stop them from occurring in the future. In certain cases, it may increase the risk of developing atrial fibrillation (AFib), a condition that can cause stroke. This isn't common but it could be life-threatening. Symptoms Premature ventricular contractions, also known as PVCs, can cause your heart seem to flutter or skip one beat. These extra heartbeats are usually harmless, but you should consult your physician if you have frequent episodes or other symptoms such as dizziness or weakness. Normally, electrical signals begin in the sinoatrial node, located in the upper right side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles expand to force blood into the lungs. They then return to the center to begin the next cycle of pumping. A PVC starts in a different place in the Purkinje fibres bundle at the left side of the heart. When PVCs occur, they make the heart beat faster or feel as if it skipped the beat. If you only have a few episodes, and there are no other symptoms, your cardiologist will probably not treat you. If you've got a number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over 24 hours. He or she may also recommend wearing a Holter monitor that will track your heartbeat over time to determine the number of PVCs you have. Anyone who has had a previous heart attack or suffer from cardiomyopathy -which alters the way the heart pumps blood should take their PVCs seriously and talk to an expert in cardiology about lifestyle changes. This includes the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough rest. A cardiologist may also prescribe medication to slow heartbeat, for example, a beta blocker. Even if there aren't any other indications however, you should have PVCs checked by a cardiologist if they happen often. These heartbeats that are irregular can point to an issue with the structure of your heart or other health conditions and, over time, when they are frequent enough, they can weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They just want to be aware 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. Patients who have a lot of them might feel like they're going to faint. They can also occur during exercising, but most athletes who experience them do not have any issues in their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to examine the heart and observe how it's working. A doctor may be able to tell whether a person has PVCs from a patient's history and physical exam. Sometimes, they may not be aware of them until they examine the patient for different reasons, like following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They may be used to detect heart disease when there is a reason to be concerned. If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment required. If your symptoms are causing you discomfort or make you be anxious, avoiding alcohol, caffeine and other over the counter decongestants, and decreasing stress can aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or are extreme, talk to your doctor about medication options to treat these symptoms. Treatment If PVCs aren't common or don't cause symptoms, they don't usually require treatment. If you experience them frequently and frequently, your doctor might want to examine for other heart conditions and recommend lifestyle changes or medication. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid of them. If you suffer from PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. It's unclear what causes them, but they're more common in people who have other heart conditions. PVCs can increase in frequency as you age, and may occur more frequently during exercises. A doctor should perform an ECG as well as an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They should also conduct an exercise stress test to see whether the additional beats are caused by physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be done to look for other reasons for the additional beats. The majority of people with PVCs are not affected and can live an ordinary life. However, they may increase the risk of developing dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout the body. A healthy and balanced diet and plenty of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat and reduce your intake of caffeine and tobacco. Sleep and stress are also important. Some medicines can also increase the risk of getting PVCs. If you're taking one of these drugs it's crucial to follow your doctor's recommendations about a healthy diet, exercise and taking your medication. Studies of patients with a high amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. This could lead to a need for a heart transplant in certain individuals.
