How a VC Can Affect Your Heart Many people have occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure. A bundle of fibers in the upper right part of your heart (the sinoatrial node, also known as SA) typically regulates your heart rhythm. Electrical signals travel to the ventricles, or lower chambers of the heart. Causes PVCs happen by the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) is not initiated. The impulse actually begins in the ventricles and causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beating or feels fluttering. They can happen infrequently and have no symptoms or they can occur frequently enough to affect your daily life. Your doctor may prescribe medication in the event that they are frequent or cause weakness, dizziness or fatigue. PVCs are generally safe and do not increase the risk of heart disease. A lot of PVCs however, may weaken the heart muscle over time. This is particularly when the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure. PVCs can trigger symptoms such as a feeling of your heart racing a beat, or the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more evident if you exercise, or consume certain beverages or foods. People with chronic stress or anxiety can have more PVCs and certain medications like amiodarone digoxin, and cocaine can increase the likelihood of developing them. If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medications. If they are a frequent occurrence, you may have to avoid some foods and beverages like alcohol and caffeine. You can also reduce your stress, and get plenty of sleep and exercise. If you have many PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. It eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. It is generally effective in treating PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib), which can lead to stroke. This is rare but can be life-threatening. Symptoms Premature ventricular contractions, also known as PVCs, can make your heart appear to flutter or skip a beat. These extra heartbeats are usually harmless, but it is important to consult your physician when you experience frequent episodes or signs like dizziness or weakness. The normal electrical signals start in the sinoatrial, located in the upper right-hand corner of the heart. They then travel to the lower chambers, or ventricles, which pump blood. The ventricles then expand to push blood into your lungs and return to the heart to start the next pumping cycle. However, a PVC begins in a different location, from the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart. When PVCs occur, they cause the heart beat or feel like it skipped the beat. If you experience only just a few episodes and there are no other symptoms the cardiologist will likely not prescribe treatment. If you've got a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. He or she might also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs. 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 consult a cardiologist regarding lifestyle modifications. These include the avoidance of alcohol, caffeine, and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat. If you have frequent PVCs even if you do not have any other symptoms, you should consult an expert in cardiology. These heartbeats that are irregular can point to an issue with the structure of your heart or other health conditions, and over time, if they occur often enough, they may weaken the heart muscle. However, most people suffering from PVCs don't have any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal. Diagnosis PVCs can feel like fluttering or skipped heartbeats, particularly when they are frequent or intense. People who experience them often might feel faint. Exercise can cause them, but most athletes who suffer from them have no heart or health problems. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. These are sticky patches that have sensors on them to record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to examine the heart and determine how it's working. Most of the time, a doctor will be able to determine if a person is suffering from PVCs from a patient's history and physical examination. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason, like following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They can be used to detect cardiac disease if there is any reason to be concerned. If your cardiologist determines your heart is structurally healthy, reassurance may be all that's needed. If your symptoms are troubling, or cause you to be anxious, avoiding alcohol, caffeine, and over the drug decongestants and reducing stress may help. Regular exercise, 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 medications that could be able to reduce the symptoms. Treatment If PVCs aren't causing symptoms or happen rarely generally, they don't require treatment. If window doctors happen frequently your doctor may want to check for heart conditions or recommend lifestyle adjustments. You might also get an intervention to get rid of them (called radiofrequency catheter ablation). If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. They're more common among people who suffer from heart issues, but it's not known the reason behind them. PVCs can become more frequent as you age, and could be more frequent during exercise. A doctor should perform an ECG along with an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They may also perform an exercise stress test to see if the extra beats are a result of physical exercise. To determine if there are other causes for the increased beats the heart catheterization or a cardiac MRI can be performed. The majority of people with PVCs have no complications and live a normal life. 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 is having difficulty pumping blood through your body. A healthy, regular diet and a lot of exercise can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium and restrict your intake of tobacco and caffeine. It is also important to get enough sleep and reduce stress. Certain medicines can also increase your risk of PVCs. If you are taking any of these medications it is crucial that you follow your doctor's advice regarding eating a healthy diet and exercising as well as taking your medication. In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. This can result in the need for a heart transplant in a few people.
