How a VC Can Affect Your HeartPVCs are common and may be experienced by a variety of people with no cause for concern. If they occur often, PVCs may weaken your heart and increase the risk of heart failure.The rhythm of your heart is usually controlled by a group of nerve fibers situated in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel from there to the lower heart chambers, or ventricles.CausesPVCs occur when the electrical impulse that typically begins your heartbeat in a region known as the sinus node (also known as the sinoatrial or SA node) does not. Instead, the impulse is generated in another area of your heart–the ventricles–and causes a wrongly timed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or feels like it’s fluttering. They may happen rarely and have no symptoms or they can happen often enough to interfere with your daily life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor might treat them with medicine.For most people, PVCs are harmless and don’t increase your risk of heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is especially true if they are caused by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.PVCs can trigger symptoms such as a feeling of your heart skipping one beat, or even the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more noticeable when you exercise or consume certain drinks or foods. PVCs are more common in people with chronic anxiety or stress. Certain medications, like digoxin, amiodarone and cocaine, may increase the risk of developing PVCs.If you have occasional PVCs Your doctor might suggest lifestyle changes and medications. If you have frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks, like caffeine and alcohol. You can also reduce your stress levels by getting enough sleep and exercising.If you have a lot of PVCs, he may suggest a medical treatment called radiofrequency catheter ablation. It destroys cells that cause PVCs. The procedure is carried out by a specialist called an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms however it does not stop them from occurring in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib), which can cause stroke. This is rare but can be life-threatening.Signs and symptomsPremature ventricular contractions or PVCs, can make your heart seem to flutter or skip the beat. These extra heartbeats are generally harmless, but you should talk to your doctor if you have frequent episodes or signs like dizziness or weakness.The electrical signals normally begin in the sinoatrial region, which is in the upper right-hand part of the heart. They then travel to the lower chambers, also known as ventricles, that pump blood. The ventricles contract to pump blood into the lungs. They return to the heart’s center to begin the next cycle of pumping. However, a PVC starts at a different spot that is separate from the bundle of fibers, known as the Purkinje fibers, in the lower left part of the heart.When PVCs occur, they can make the heart pound or feel like it skipped a beat. If you experience just a few episodes but no other symptoms, your doctor probably won’t be able to treat you. But if you have a large number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG to determine your heart rate over the course of 24 hours. The doctor may also recommend wearing a Holter monitor that will track your heartbeat over time to determine how many PVCs you have.If you’ve had a prior heart attack or suffer from cardiomyopathy -which alters the way the heart pumps blood – should take their PVCs seriously and talk to an expert in cardiology about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, managing anxiety and stress and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.If you have frequent PVCs even if don’t have any other symptoms, you should consult an expert in cardiology. These extra heartbeats can point to problems with the structure of your heart or other health issues and, over time if they occur often enough, they can weaken the heart muscle. The majority of people with PVCs don’t experience any problems. They just want to be aware that the fluttering or skipping heartbeats aren’t normal.DiagnosisPVCs can be felt as fluttering or skipped heartbeats, especially if they’re intense or frequent. People who experience them regularly may feel faint. They can also happen with exercise, though many athletes who get them do not have any issues with their health or heart. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.A doctor will usually be able to determine if a patient has PVCs by looking at them and taking a medical history. However, sometimes they will only be able to detect them when they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They are able to identify cardiac problems if there is any concerns.If your cardiologist determines that your heart is structurally normal, reassurance will be the only treatment needed. If your symptoms are bothersome, or cause you to feel anxious, staying away from alcohol, caffeine and other over the counter decongestants, and decreasing stress can help. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms continue or are extreme, talk to your doctor about medication options to treat them.TreatmentIf PVCs are rare or don’t cause symptoms, they don’t usually require treatment. If they are frequent, your doctor might need to examine for heart conditions or recommend lifestyle adjustments. 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 causes your heartbeat begins somewhere other than at the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. It’s not known what causes them, but they’re more common in people with other heart problems. PVCs can increase in frequency as you age, and may occur more often during exercise.If a patient has frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also likely perform an exercise stress test in order to determine if the additional heartbeats are due to physical exercise. To determine whether there are other reasons for the extra beatings the heart catheterization or a cardiac MRI can be performed.the window doctor of people who suffer from PVCs don’t experience any problems and can enjoy 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, that means the heart muscle gets weaker and has trouble pumping blood through your body.Regular exercise and a healthy 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. It is also important to sleep enough and manage stress. Certain medicines can also increase the risk of developing PVCs. So if you take one of these drugs it’s crucial to follow your doctor’s instructions about a healthy diet, exercise and taking your medication.In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Certain people may require an organ transplant.
