How a VC Can Affect Your Heart Many people experience occasional PVCs without any problems. If they occur often, PVCs may weaken your heart and increase your chance of suffering from heart failure. window doctor near me of fibers located in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) usually controls the heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers, or ventricles. Causes PVCs are caused when the electrical impulse that normally starts your heartbeat in a part called the sinus node (also known as the sinoatrial or SA node) doesn't. Instead, the impulse starts in a different area of your heart, the ventricles, and causes an untimed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beating or feels like it is fluttering. They can happen infrequently, causing no symptoms, but they may be frequent enough to affect your standard of living. If they are very frequent or cause dizziness, weakness or fatigue, your doctor could treat them with medicine. For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. Frequent PVCs however, could weaken your heart muscle over time. This is especially relevant if they are triggered by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure. The signs of PVCs include feeling like your heart beats faster or it flutters. You may feel breathless. The fluttering can be more evident when you exercise or eat or drink certain beverages or foods. People who suffer from chronic anxiety or stress can have more PVCs, and some drugs like amiodarone digoxin, and cocaine may increase the chance of developing them. If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medications. If you are prone to frequent PVCs, your doctor might recommend that you avoid certain foods and drinks such as alcohol and caffeine. You can also reduce stress by having enough sleep and working out. If you have a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. This procedure is performed by a specialist known as 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 your risk of having atrial fibrillation (AFib) which could result in a stroke. It is not common, but it could be life-threatening. Signs and symptoms Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or be fluttering. These extra heartbeats are usually harmless, but you should talk to your doctor when you experience frequent episodes or other symptoms such as dizziness or weakness. The normal electrical signals start in the sinoatrial, located in the upper right part of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles expand to force blood into the lung. They then return to the center to begin the next cycle of pumping. A PVC starts at a different spot that is the Purkinje fibres bundle in the bottom left of the heart. When PVCs occur, they cause the heart beat faster or feel as if it skipped the beat. If you experience only a few episodes, and no other symptoms are present the cardiologist will likely not prescribe treatment. If you have a lot of PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. The doctor may also recommend wearing a Holter monitor that will track your heartbeat over time to determine the number of PVCs you have. People who have suffered an earlier heart attack or cardiomyopathy, a condition which affects the heart's blood flow - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. These include avoiding alcohol, caffeine and smoking, managing anxiety and stress, and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat. If you experience frequent PVCs even if you do not have any other symptoms you should see a cardiologist. These irregular heartbeats could point to problems with the structure of your heart or other health conditions and, over time, if they occur often enough, they may weaken the heart muscle. But the majority of people suffering from PVCs don't have any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal. Diagnosis PVCs may be felt as fluttering or skipped heartbeats, especially if they are frequent or intense. People who get lots of them might feel like they're about to faint. They can also happen with exercising, but most athletes who get them do not have any issues with their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors that record electrical impulses from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart. A doctor can often tell the presence of PVCs by looking at them and taking a medical history. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason, like following an accident or surgical procedure. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias and can be used if there's any concern of cardiac disease. If your cardiologist has determined that your heart is structurally healthy, reassurance may be all you need. If your symptoms are causing you discomfort or cause you to feel anxious, avoiding alcohol, caffeine and other over the counter decongestants, and reducing stress may help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medications that could help manage these symptoms. Treatment If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If they are frequent, your doctor might need to examine for heart problems or suggest lifestyle changes. You could also have a procedure (called radiofrequency cathode ablation) to eliminate of them. If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This could cause your heart to feel as if it skips beats or has additional beats. It's not clear what causes these, but they're more common in people with other heart conditions. PVCs can increase in frequency as you age, and may occur more frequently during exercise. A doctor should perform an ECG and an echocardiogram on a patient that has frequent and painful PVCs to rule out structural heart diseases. They should also conduct an exercise stress test to determine if the extra beats are a result of physical activity. To find out if there are other causes for the extra beats an invasive heart catheterization or a cardiac MRI is possible. Most people with PVCs are not affected and can lead the normal life. But they can increase your risk of having dangerous heart rhythm problems particularly if you have certain patterns of them. In certain cases, it means that the heart muscle becomes weaker and is having difficulty pumping blood throughout your body. Regular exercise and a balanced diet will reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat, and you should also reduce your intake of caffeine and tobacco. Sleep and stress are equally crucial. Certain medications can increase the risk of developing PVCs. If you're taking one of these medications it is important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication. Studies of patients who had a high amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require a heart transplant.
