How a VC Can Affect Your HeartA lot of people experience occasional PVCs without any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial, or SA, node) usually controls your heart rhythm. Electrical signals travel to the ventricles, or lower chambers of the heart.CausesPVCs occur when the electrical impulse that normally starts your heartbeat in a region called the sinus node (also called the sinoatrial or SA Node) isn’t. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beat or feels fluttering. They may happen rarely and not cause any symptoms, or they may occur frequently enough to interfere with your quality of life. If they occur frequently or cause weakness, dizziness or fatigue, your doctor might treat them with medication.PVCs are generally harmless and don’t increase the risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is particularly relevant if they are triggered by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.The symptoms of PVCs include a feeling that your heart beats faster or is fluttering, and you feel breathless. The fluttering may be more noticeable when you exercise or consume certain drinks or foods. PVCs are more common for those who suffer from chronic stress or anxiety. Some medications, such as digoxin, amiodarone or cocaine, can increase the risk of developing PVCs.If you experience occasional PVCs Your doctor might recommend lifestyle changes and medicines. If they are a frequent occurrence, you may need to avoid certain drinks and foods like caffeine and alcohol. You can also lower your stress by getting enough sleep and working out.If you’ve got a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It destroys the cells that cause them. Electrophysiologists are the ones who execute this procedure. The treatment is usually effective in treating PVCs, reducing symptoms but it does not stop them from returning in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib), which can result in a stroke. It’s not common, but it 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 harmless, however you might need to see your doctor if they are frequent or if you experience symptoms like dizziness, or fatigue.Normally, electrical signals begin at the sinoatrial junction, which is in the top right portion of the heart. They travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles expand to push blood into the lungs, and return to the heart and start the next pumping cycle. But a PVC begins at a different spot, from the bundle of fibers, known as the Purkinje fibers, in the left-hand side of the heart.When PVCs occur, they can make the heart beat faster or feel like it skipped a beat. If the window doctor have only a few episodes, and no other symptoms are present the cardiologist will likely not treat you. But if you have a lot of PVCs the doctor may recommend an electrocardiogram, or ECG to gauge your heartbeat over a 24-hour period. They might also recommend wearing a Holter monitor that records your heartbeat over time to see the number of PVCs you have.People who have had a prior heart attack or suffer from cardiomyopathy — a condition that alters the way the heart pumps blood — should take their PVCs seriously and speak with a cardiologist about changes to their lifestyle. These include the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough sleep. A cardiologist can also prescribe medication to slow the heartbeat such as a beta blocker.Even if you don’t have any other indications however, you should have PVCs checked by an expert in cardiology if they occur frequently. These heartbeats that are irregular can point to an issue with the structure of your heart or other health conditions, and over time, if they occur often enough, they could weaken the heart muscle. However, most people suffering from PVCs don’t experience any problems. They want to know if the rapid heartbeats, or the skipping of heartbeats is normal.DiagnosisPVCs can feel like heartbeats that are fluttering particularly if they’re frequent and intense. People who experience them frequently might feel faint. Exercise can cause them, but many athletes who suffer from these symptoms do not have heart or health problems. PVCs can show up on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors that record electrical signals from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and see how it’s working.Often, a doctor will be able to determine if a person is suffering from PVCs through a medical history and physical examination. Sometimes however, they might not be aware of PVCs until they examine a patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to detect heart disease if there is any concerns.If your cardiologist finds that your heart is structurally normal, reassurance is the only treatment required. However, if your symptoms are causing discomfort or make you feel anxious, staying away from alcohol, caffeine and other decongestants as well as reducing stress levels can aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If the symptoms persist or are severe, speak to your doctor about medications that can control these symptoms.TreatmentIf PVCs aren’t common or don’t cause symptoms, they do not usually require treatment. If they occur frequently your doctor may want to check for heart conditions or recommend lifestyle changes. You could also have an operation (called radiofrequency cathode ablation) to eliminate of them.If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere outside of 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 a beating or has additional beats. PVCs are more prevalent among people suffering from heart disease, but it’s not known the reason behind them. PVCs can increase in frequency as you age, and may occur more often during exercise.A doctor should conduct an ECG along with an echocardiogram for a patient who has frequent and painful PVCs to rule out structural heart diseases. The doctor may also perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be done to look for other causes for the extra beats.Most people who suffer from PVCs do not suffer from any complications and can lead a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some instances, this means the heart muscle gets weaker and is unable to pump blood through your body.A healthy, regular diet and regular exercise can reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat, and limit your intake of tobacco and caffeine. It is also important to get enough rest and reduce stress. Certain medicines can also increase your risk of getting PVCs. If you take any of these medications, it is important to follow the advice of your doctor about eating healthy and exercising as well as taking your medication.In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. This can lead to the need for a heart transplant in certain patients.
