How a VC Can Affect Your Heart PVCs are common and can be experienced by a variety of people with no cause for concern. If they happen frequently, PVCs may weaken your heart and increase the risk of heart failure. The rhythm of your heart is controlled by a bundle of fibers that are located in the upper right-hand part of your heart. This is known as the sinoatrial node, or SA. Electrical signals travel from this node to the lower chambers of your heart or ventricles. Causes PVCs happen when the electrical impulse that usually begins your heartbeat in a part known as the sinus node (also called the sinoatrial or SA node) does not. The impulse actually begins in the ventricles, which causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia and 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 may occur frequently enough to interfere with your daily life. Your doctor may prescribe medicine if they are frequent or cause weakness, dizziness or fatigue. For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health problems. Regular PVCs, however, can weaken your heart muscle over time. This is particularly true if they are caused by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure. The symptoms of PVCs include feeling like your heart beats slower or flutters, and you may feel exhausted. The fluttering could be more evident when you exercise or have certain drinks or food items. PVCs are more prevalent in people with chronic anxiety or stress. Some drugs, like digoxin, amiodarone, and cocaine, may increase the risk. If you have occasional PVCs your doctor may suggest lifestyle changes and medications. If you have frequent PVCs, your physician may recommend avoiding certain drinks and foods, such as alcohol and caffeine. You can also lower your stress by getting enough sleep and working out. If you've got 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. Electrophysiologists are the ones who perform this procedure. The treatment is generally effective in treating PVCs and reducing symptoms, but it does not stop them from recurring in the future. In certain cases it can increase the risk of developing atrial fibrillation (AFib) which can result in stroke. This is rare but can be life-threatening. Signs and symptoms Premature ventricular contractures PVCs, also known as PVCs, can cause your heart to skip or flutter. These heartbeats can be harmless, but you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness. Normally, electrical signals start in the sinoatrial node located in the upper right-hand side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles expand to push the blood into the lungs. They then return to the center to begin the next cycle of pumping. But a PVC begins at a different spot that is separate from the bundle of fibers called the Purkinje fibers, in the left-hand side of the heart. When PVCs occur they can make the heart appear to be beating faster or slower. If you experience only a few episodes, and there are no other symptoms, your cardiologist will probably not be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. They may also suggest wearing a Holter monitor that records your heartbeat over time, allowing you to see how many PVCs you have. People who have suffered previously from a heart attack or have suffered from cardiomyopathy – an illness that affects method by which the heart pumps blood – must take their PVCs seriously and speak to a cardiologist regarding lifestyle changes. These include abstaining from alcohol, caffeine and smoking, managing anxiety and stress and getting enough sleep. A cardiologist can also prescribe medication to slow heartbeat, for example, a beta blocker. If you are experiencing frequent PVCs, even if you do not have other signs, you should see a cardiologist. These extra heartbeats may be a sign of a problem with the structure of your heart or lungs and if they occur often enough, it could weaken the heart muscle. window doctor of people with PVCs do not experience any issues. They simply want to be aware that the fluttering and racing heartbeats aren't normal. Diagnosis PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience a lot of them might feel like they're about to faint. Exercise can trigger PVCs, but a lot of athletes who experience them have no heart or health issues. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to look at the heart and see how it's functioning. Often, a doctor will be able to determine if a person is suffering from PVCs from a patient's history and physical exam. However, sometimes they will only notice them while examining the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias, and could be utilized in the event of any suspicion of heart disease. If your cardiologist has determined that your heart is structurally healthy, reassurance could be all you need. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medication that could be able to reduce these symptoms. Treatment If PVCs aren't common or don't cause symptoms, they rarely need treatment. If they happen frequently, your doctor might need to examine for heart problems or suggest lifestyle modifications. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid them. When you have PVCs The electrical signal that triggers your heartbeat starts somewhere other than the sinoatrial node (SA node) located in the upper right part of your heart. This can make it feel like your heart skips beats or is beating faster. PVCs are more prevalent among people suffering from heart disease, but it's not known what causes them. PVCs can become more frequent as you age, and might occur more frequently during exercises. If a patient experiences frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out heart disease that is structural. They should also conduct an exercise stress test to see if the extra beats are a result of physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other causes for the extra beats. Most people with PVCs have no complications and can lead the normal life. They can increase the risk of dangerous heart rhythm disorders, especially if they occur in certain patterns. In some cases, that means that the heart muscle becomes weaker and has trouble pumping blood through your body. A healthy and balanced diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat and limit caffeine and tobacco. Sleep and stress are also important. Certain medicines can also increase your risk of getting PVCs. If you're taking one of these medications, it's important to follow the doctor's advice regarding eating healthy, exercising and taking your medication. Studies of patients with a high burden of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. This could lead to the need for a heart transplant in a few people.
