How a VC Can Affect Your Heart PVCs are commonplace and can be experienced by a wide range of people without causing any issues. If they occur often, PVCs may weaken your heart and increase your chance of suffering from heart failure. The rhythm of your heart is controlled by a group of fibers located in the upper right-hand corner of your heart. This is known as the sinoatrial node or SA. Electrical signals travel to ventricles or lower chambers of your heart. Causes PVCs occur when the electrical impulse that typically begins your heartbeat in a region called the sinus node (also known as the sinoatrial node or SA node) isn't. Instead, the impulse begins in another area of your heart—the ventricles—and causes a wrongly timed beat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels fluttering. They may occur infrequently without causing any symptoms, but they may occur frequently enough to impact your quality of life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor could treat them with medication. PVCs are generally harmless and don't increase the risk of heart disease. In time, repeated PVCs can weaken the heart muscle. This is particularly when the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure. PVCs can trigger symptoms such as a feeling of your heart racing an beat, or the feeling of your heart fluttering. You might also feel breathless. The fluttering could be more noticeable when you exercise or eat or drink certain drinks or foods. PVCs are more common in those suffering from chronic anxiety or stress. Some drugs, like digoxin, amiodarone or cocaine, can increase the risk. If you experience occasional PVCs your doctor may suggest lifestyle changes and medications. If they're a frequent occurrence, you may need to avoid certain drinks and foods like caffeine and alcohol. You can also take steps to lessen your stress, and take advantage of plenty of rest and exercise. If you're suffering from many PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation. This destroys cells that cause PVCs. This is done by a specialist known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can result in stroke. This is rare but it could be life-threatening. Symptoms Premature ventricular contractions or PVCs, may make your heart appear to skip or flutter one beat. These heartbeats can be harmless, but it is important to talk to your doctor when you experience frequent episodes or symptoms like dizziness or weakness. Normaly, electrical signals begin in the sinoatrial region, which is in the upper right corner of the heart. They then move to the lower chambers, also known as ventricles, which pump blood. The ventricles expand to push the blood into the lungs. They return to the heart's center to begin the next cycle of pumping. A PVC starts at a different spot that is the Purkinje fibres bundle at the left side of the heart. When PVCs occur, they make the heart beat or feel as if it skipped a beat. If you experience a few episodes and no other symptoms, the doctor probably won't be able to treat you. If you have many PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. The doctor might also recommend wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see how many PVCs you have. Anyone who has suffered a previous heart attack or have suffered from cardiomyopathy – a condition which affects the method by which the heart pumps blood – should take their PVCs very seriously and speak to a cardiologist about lifestyle changes. These include avoiding caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat. Even if the window doctor don't experience any other signs, you should still get PVCs checked by a cardiologist if they happen frequently. These heartbeats that are irregular could signal a problem with the structure of your lungs or heart, and if they occur frequently enough, can weaken your heart muscle. However, most people with PVCs don't experience any problems. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal. Diagnosis PVCs might feel like fluttering or skipped heartbeats, especially when they're frequent or intense. People who experience them frequently might feel faint. They can also occur with exercise, though many athletes who suffer from them do not have any issues in their heart or health. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and see how it's working. A doctor can often tell if a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes however, they might not be aware of PVCs until they examine a patient for another reason such as following an accident or a surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias, and they might be used if there's any concern of heart disease. If your cardiologist concludes that your heart is structurally healthy, reassurance may be all you need. If your symptoms are causing discomfort or make you feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress may aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your doctor about medications that may be able to manage them. Treatment If PVCs don't cause symptoms or occur rarely, they usually don't need treatment. If you are frequently affected or frequently, your doctor may wish to examine for any other heart problems and suggest lifestyle changes or medications. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them. If you have PVCs in your heart, the electrical signal which creates your heartbeat is located different than the sinoatrial (SA) node that is located in the upper right corner of your heart. This can cause your heart to feel as if it skips a beating or has extra beats. It's not clear what causes these symptoms, but they're frequent in those with other heart issues. PVCs are more likely to occur as you age, and may be more frequent during exercises. If a patient has frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely conduct an exercise stress test in order to determine if the extra heartbeats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be done to look for other causes of the extra beats. The majority of people who suffer from PVCs don't experience any issues and can live an ordinary life. They can increase your risk for 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 it is more difficult to pump blood throughout the body. Regular exercise and a healthy diet can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium and limit your intake of tobacco and caffeine. You should also try to get enough sleep and manage stress. Some medicines may also increase your risk for PVCs. If you take any of these medicines it is essential that you follow the advice of your doctor regarding eating a healthy diet exercising, as well as taking your medication. Studies of patients with a high burden of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to the need for a transplant in some patients.
