How a VC Can Affect Your Heart Many people experience occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase your risk of heart failure. Repair My Windows And Doors of fibers in the top right portion of your heart (the sinoatrial node, also known as SA) usually controls your heart rhythm. Electrical signals travel to the ventricles or lower chambers of your heart. Causes PVCs occur when the electrical impulse that normally begins your heartbeat in a region known as the sinus node (also known as the sinoatrial node or SA node) doesn't. The impulse actually begins in the ventricles and causes an untimed heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. They may feel like the heart beats faster or feels fluttering. They may happen rarely and not cause any symptoms, or they can occur frequently enough to impact your daily 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 developing heart disease. In time, repeated PVCs can weaken the heart muscle. This is particularly when the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure. PVCs can cause symptoms, such as a sensation of your heart skipping one beat, or even the feeling of your heart fluttering. You may also feel breathless. The fluttering could be more apparent if you exercise, or consume certain beverages or foods. People who suffer from chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the chance of developing them. If you have occasional PVCs Your doctor might suggest lifestyle changes and medication. If you are prone to frequent PVCs, your physician may recommend avoiding certain foods and drinks, such as caffeine and alcohol. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise. If you've got a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. This is done by a specialist called an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms however, it doesn't prevent them from recurring in the future. In certain instances, it can increase the risk of having 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 flutter. These extra heartbeats are usually harmless, however, you should talk to your doctor in case you experience frequent episodes or other symptoms such as dizziness or weakness. Normally, electrical signals start at the sinoatrial junction, located in the top right side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles contract to propel the blood into the lungs, and then return to the heart and start the next cycle of pumping. However, a PVC begins in a different place, from the bundle of fibers, known as the Purkinje fibers, located in the bottom left portion of the heart. When PVCs happen, the heart may feel as if it's racing or pounding. If you experience only one or two episodes, and there are no other symptoms the cardiologist will likely not prescribe treatment. However, if you have lot of PVCs, the doctor may suggest an electrocardiogram, or ECG to determine your heart rate over a 24-hour period. The doctor may also suggest wearing a Holter Monitor which tracks the heart's rhythm and count the number of PVCs. Anyone who has suffered previously from a heart attack or cardiomyopathy, an illness that affects the way the heart pumps blood – must take their PVCs seriously and speak to an expert in cardiology about lifestyle modifications. Those include avoiding caffeine, alcohol and smoking, managing anxiety and stress and getting enough sleep. A cardiologist may prescribe beta blockers to slow down the heartbeat. If you have frequent PVCs even if you do not have any other symptoms you should see an expert in cardiology. These heartbeats that are irregular could be a sign of a problem with the structure of your heart or lungs and if they happen often enough, it could weaken the heart muscle. However, most people suffering from PVCs don't experience any problems. They just want to be aware that the fluttering or skippy heartbeats aren't typical. Diagnosis PVCs can feel like fluttering or skipped heartbeats, especially if they're intense or frequent. People who get lots of them may feel they're going to faint. They can also happen with exercise, though many athletes who get them don't have issues with their health or heart. PVCs can show up on tests such as an electrocardiogram 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 observe how it's functioning. A doctor will usually be able to determine the presence of PVCs by looking at them and taking a medical history. Sometimes, however, they may not be aware of PVCs until they examine a patient for another reason such as following an accident or surgery. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias and they might be used in the event of any suspicion of heart disease. If your cardiologist determines that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are troubling or cause you to feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Regular exercise, being at a healthy weight and drinking enough fluids can decrease the likelihood of PVCs. If your symptoms persist or are severe, talk to your doctor about treatments that could help control these symptoms. Treatment If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If you experience them frequently, your doctor may want to examine for other heart issues and suggest lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them. If you have 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 can make it feel like your heart skips beats or has extra beats. It's not known what causes these symptoms, but they're frequent in those with other heart conditions. PVCs are more frequent as you age, and may occur more frequently during exercising. If a patient has frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. They should also conduct an exercise stress test to determine whether the extra beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion studies can be conducted to determine other reasons for the additional beats. Most people with PVCs do not have any issues and can live an ordinary life. They may increase the risk of heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body. A healthy, regular diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat, and you should also reduce your intake of caffeine and tobacco. Sleep and stress are equally crucial. Certain medicines can also increase your risk for PVCs. If you are taking any of these medicines it is crucial that you follow your doctor's recommendations about eating healthy and exercising as well as taking your medication. Studies of patients suffering from a high amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require a heart transplant.
