How a VC Can Affect Your Heart PVCs are common and can be experienced by a wide range of people without causing any problems. If they occur often, PVCs may weaken your heart and increase the chance of suffering from heart failure. A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial or SA node) typically controls your heart rhythm. Electrical signals travel from there to the lower chambers of your heart, or ventricles. Causes PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different area of your heart called the ventricles and triggers a mistimed beat. These extra beats, also called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat, or it feels like it is like it is fluttering. They can happen infrequently, causing no symptoms, but they may also happen frequently enough to affect your standard of life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor might treat them with medication. PVCs are generally harmless and don't increase your risk of heart disease. Regular PVCs however, may weaken the heart muscle over time. This is particularly true if they are caused by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure. PVCs can cause symptoms like a feeling of your heart racing an beat, or fluttering. You may also feel breathless. The fluttering could be more noticeable when you exercise, or consume certain drinks or foods. People who experience chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin, and cocaine can increase the risk of developing them. If you have occasional PVCs Your doctor might recommend lifestyle changes and medicines. If you have frequent PVCs, your doctor might recommend avoiding certain foods and drinks, such as alcohol and caffeine. You can also take steps to reduce your stress, and get plenty of sleep and exercise. If you have a lot of PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It destroys cells that cause PVCs. This procedure is performed by a specialist, known as an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib) which is an illness that can lead to stroke. This is rare but it could be life-threatening. Symptoms Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or to flutter. These heartbeats that are not normal can be harmless, but you might want to consult your doctor if they are frequent or if you notice symptoms like dizziness, or fatigue. The normal electrical signals start in the sinoatrial region, which is in the upper right part of the heart. They then travel to the lower chambers, or ventricles, where blood pumps are located. The ventricles expand to pump blood into the lung. They return to the center to start the next cycle of pumping. A PVC starts at a different spot in the Purkinje fibers are located in the left-hand side of the heart. When PVCs happen they can make the heart appear to be beating faster or slower. If you only have a few episodes, and no other symptoms are present the cardiologist will likely not treat you. However, if you have lot of PVCs, the doctor may recommend an electrocardiogram, or ECG to gauge your heart rate over a 24-hour period. He or she may also recommend wearing a Holter monitor that records your heartbeat over time, allowing you to see the number of PVCs you have. People who have had a previous heart attack or have cardiomyopathy -which alters the way the heart pumps blood must be aware of their PVCs and talk to a cardiologist about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat. If you have frequent PVCs, even if you don't have any other symptoms you should see a cardiologist. These heartbeats that are irregular could signal a problem with the structure of your heart or lungs, and if they happen often enough, it could weaken your heart muscle. But the majority of people with PVCs don't have any issues. They simply want to know that the fluttering or racing heartbeats aren't normal. Diagnosis PVCs can feel like heartbeats that are fluttering especially if they are frequent and intense. People who experience a lot of them might feel like they're going to faint. Exercise can trigger them, but many athletes who suffer from these symptoms do not have heart or health issues. PVCs can show up in tests like an electrocardiogram, or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart. A doctor can often tell whether a patient has PVCs by examining them and taking their medical history. Sometimes, however, they may not be aware of PVCs until they examine patients for a different reason such as following an accident or surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias and can be used if there's any concern of a cardiac condition. If your cardiologist finds that your heart's structure is normal, reassurance is the only treatment required. However, if your symptoms are bothersome or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms continue or are severe, speak to your doctor about possible medication options to treat these symptoms. Treatment If PVCs are rare or do not cause symptoms, they don't usually require treatment. If they happen frequently your doctor may want to check for heart problems or suggest lifestyle modifications. You could also have an intervention to get rid of them (called radiofrequency catheter ablation). When you have PVCs the electrical signal that triggers your heartbeat begins somewhere other than the sinoatrial node (SA node) in the top right part of your heart. This could cause your heart to feel as if it skips beats or has extra beats. They're more common among people who suffer from heart issues however, it's not clear what causes them. PVCs may increase in frequency as you age, and may be more frequent during exercising. A doctor should conduct an ECG as well as an echocardiogram on a patient that suffers from frequent and painful PVCs to rule out structural heart diseases. The doctor may also conduct an exercise stress test in order to determine if the extra heartbeats are related to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other causes of the increased beats. Most people who suffer from PVCs do not experience any problems and can enjoy a normal lifestyle. But they can increase your risk of having dangerous heart rhythm problems, especially if you have certain patterns of them. In some instances, this means the heart muscle gets weaker and is unable to pump blood through your body. Regular exercise and a balanced diet can lower the chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your consumption of tobacco and caffeine. You should also try to get enough rest and reduce stress. Certain medicines can also increase your risk for PVCs. So if you take one of these medicines, it's important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication. the window doctor of patients with a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some people may need a heart transplant.
