How a VC Can Affect Your Heart PVCs are common and may be experienced by a variety of people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure. The heart's rhythm is controlled by a bundle of fibers that are located in the upper right-hand part of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel to lower heart chambers or ventricles. Causes PVCs are caused when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. The impulse actually begins in the ventricles, which causes a mistimed heartbeat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart beats faster or feels like it is fluttering. They can happen infrequently and cause no symptoms, or they can occur frequently enough to affect your daily life. If they are very frequent or cause dizziness, weakness, or fatigue, your doctor might treat them with medication. PVCs are generally harmless and don't increase the risk of heart disease. A lot of PVCs however, could weaken the heart muscle over time. This is particularly true if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure. The signs of PVCs include feeling like your heart beats slower or it flutters. You may feel breathless. The fluttering can be more evident when you exercise or have certain drinks or foods. People who suffer from chronic stress or anxiety can have more PVCs and certain drugs like amiodarone digoxin, and cocaine may increase the likelihood of developing them. If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as alcohol and caffeine. You can also reduce your stress by having enough sleep and exercising. If you have many PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. The procedure is carried out by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but does not prevent them from returning in the future. In some instances it can increase the risk of developing atrial fibrillation (AFib), which can lead to stroke. It is not common, but it could be life-threatening. Symptoms Premature ventricular contractions, or PVCs, can cause your heart seem to flutter or skip a beat. These heartbeats that are not normal can be harmless, but you might want to consult your doctor if they are frequent or if you are experiencing symptoms like dizziness, or fatigue. Normally, electrical signals begin at the sinoatrial junction, located in the upper right-hand side of the heart, and descend to the lower chambers (or ventricles) that pump blood. The ventricles contract to propel blood into your lungs, and then return to your heart and start the next pumping cycle. A PVC begins at a different spot that is the Purkinje fibres bundle at the left side of the heart. When PVCs happen, the heart may feel like it is skipping a beat or pounding. If you have a few episodes and no other symptoms, your doctor will probably not treat you. However, if you have number of PVCs the doctor may recommend an electrocardiogram, or ECG to determine your heartbeat over 24 hours. He or she may also recommend wearing a Holter monitor that records your heart rhythm over time to see how many PVCs you have. People who have suffered a previous heart attack or cardiomyopathy – an illness that affects the way the heart pumps blood – should take their PVCs seriously and speak to a cardiologist regarding lifestyle changes. upvc window doctor includes the avoidance of alcohol, caffeine, and smoking, reducing anxiety and stress and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow the heartbeat. If you have frequent PVCs even if do not have other signs, you should see an expert in cardiology. These heartbeats that are irregular can indicate an issue with the structure of your heart or other health issues, and over time, when they are frequent enough, they could weaken the heart muscle. Most people who suffer from PVCs do not have any issues. They just want to be aware that the fluttering or skipping heartbeats aren't normal. Diagnosis PVCs may feel like heartbeats that flutter, particularly if they're frequent and intense. People who experience them regularly may feel weak. Exercise can trigger them, but most athletes who experience them have no heart or health problems. PVCs may show up on tests such as an electrocardiogram or Holter monitor. These are sticky patches that have sensors that record electrical signals from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart. A doctor can often tell the presence of PVCs by looking at them and taking a medical history. Sometimes, however, they may only notice PVCs when examining patients for a different reason, such as after an accident or surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition. If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are causing you discomfort, or cause you to feel anxious, staying away from alcohol, caffeine, and over the drug decongestants and reducing stress may help. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can reduce your episodes of PVCs. If your symptoms are persistent or severe, speak to your physician about the medications that could be able to control them. Treatment If PVCs aren't common or don't cause symptoms, they do not usually require treatment. If you have them often, your doctor may want to examine for any other heart problems and recommend lifestyle changes or medicine. You might also get an intervention to get rid of them (called radiofrequency catheter ablation). If you have PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can cause your heart to feel like it skips beats or has additional beats. It's unclear what causes these, but they're more common in people who have other heart conditions. PVCs are more frequent with age and might happen more often during exercising. A doctor should conduct an ECG and an echocardiogram on a patient who has frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to determine whether the extra beats are a result of physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes of the additional beats. The majority of people with PVCs have no complications and live a normal life. They can increase the risk of developing heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body. Regular exercise and a balanced diet will lower the risk of developing PVCs. Avoid foods that are high in fat and sodium, and you should also reduce your intake of caffeine and tobacco. Also, you should try to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you take any of these medicines, it is important to follow the advice of your doctor 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 heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. This can lead to a need for a heart transplant in a few individuals.
