How a VC Can Affect Your HeartMany people experience occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.The heart's rhythm is usually controlled by a group of fibers that are located in the upper right-hand corner of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from this node to the lower chambers of your heart or ventricles.CausesPVCs happen when the electrical impulse that usually initiates your heartbeat in a part called the sinus node (also known as the sinoatrial or SA node) does not. The impulse actually begins in the ventricles, which causes an untimed 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, causing no symptoms, but they can also happen frequently enough to affect your standard of life. Your doctor might prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.In most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is especially true if they are caused by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.PVCs can cause symptoms such as a feeling of your heart beating a beat, or fluttering. It is also possible to feel breathless. The fluttering can be more evident when you exercise or have certain drinks or food items. PVCs are more prevalent in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone and cocaine, can also increase their risk.If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medication. If they are a regular occurrence, you may have to avoid some foods and beverages, such as caffeine and alcohol. You can also reduce stress by taking enough rest and exercising.If you have many PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. This is done by a specialist called an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In some instances, it can increase the risk of developing atrial fibrillation (AFib) which could cause a stroke. It's not common, but it can be life-threatening.SymptomsPremature ventricular contractions, also known as PVCs, can cause your heart seem to skip or flutter a beat. These extra heartbeats are usually harmless, however, you should talk to your doctor if you have frequent episodes or symptoms like dizziness or weakness.The electrical signals typically begin in the sinoatrial node located in the upper right side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to propel blood into the lungs, and then return to the heart to begin the next pumping cycle. A PVC begins at a different spot, the Purkinje fibers are located in the left side of the heart.When PVCs occur, the heart may appear to be skipping a beat or pounding. If you've experienced a few episodes and no other symptoms, your doctor probably won't be able to treat you. If you've got a lot of PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter monitor that records the heart's rhythm over time to determine the number of PVCs you have.People who have had a prior heart attack or have cardiomyopathy -- a condition that affects the way that the heart pumps bloodand should be aware of their PVCs and talk to a cardiologist about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.If you are experiencing frequent PVCs even if you do not have other symptoms you should see an expert in cardiology. These irregular heartbeats could be a sign of an issue with the structure of your heart or other health conditions, and over time, when they are frequent enough, they may weaken the heart muscle. the window doctor who suffer from PVCs do not experience any issues. They just want to be aware that the fluttering and skipping heartbeats aren't normal.DiagnosisPVCs can be akin to heartbeats that flutter, especially if they are frequent and intense. People who experience them regularly may feel faint. They can also occur with exercise, though many athletes who experience them don't have issues with their health or heart. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.Most of the time, a doctor will be able to determine if someone has PVCs from a patient's history and physical exam. But sometimes they might not be aware of them until they examine the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitoring systems can also aid in detecting PVCs and other arrhythmias, and could be utilized if there's any concern of a cardiac condition.If your cardiologist determines your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are causing discomfort or make you feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress may aid. Getting regular exercise, staying at a healthy weight and drinking enough water can help reduce the frequency of PVCs. If your symptoms persist or severe, speak to your doctor about medication that could be able to reduce these symptoms.TreatmentIf PVCs are rare or do not cause symptoms, they do not usually require treatment. If they happen frequently your doctor may want to check for heart problems or suggest lifestyle changes. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause your heart to feel as if it skips beats or has additional beats. PVCs are more prevalent among people with heart problems however, it's not clear the reason behind them. PVCs may increase in frequency as you age, and could be more frequent during exercise.A doctor should conduct an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to determine if there are structural heart problems. They will probably also do an exercise stress test to see whether the additional beats are caused by physical activity. To find out if there are other causes for the increased beats the heart catheterization or a cardiac MRI is possible.The majority of people with PVCs do not suffer from any complications and can lead a normal lifestyle. They may increase the risk of developing dangerous heart rhythm disorders, especially if they occur in certain patterns. In certain cases, it means that your heart muscle gets weaker and is unable to pump blood throughout your body.Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco. It is also important to get enough rest and reduce stress. Certain medications can increase the risk of developing PVCs. If you're taking one of these medicines, it's important to follow your doctor's instructions regarding eating healthy, exercising and taking your medication.In studies of patients with PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. This can result in the need for a heart transplant in certain people.
