How a VC Can Affect Your Heart PVCs are common and may be experienced by many people without causing any issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure. The rhythm of your heart is usually controlled by a bundle of fibers that are located in the upper right-hand part of your heart. This is known as the sinoatrial node, or SA. Electrical signals are transmitted from there to the lower chambers of your heart or ventricles. Causes PVCs are caused when the electrical impulse which normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, causing an untimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat or feels like it's fluttering. They can happen infrequently without causing any symptoms, but they could also happen frequently enough to affect your quality of living. Your doctor may prescribe medicine if they are frequent or cause dizziness, weakness or fatigue. For most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is particularly when the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can lead to heart failure. PVCs can cause symptoms, such as a sensation of your heart skipping one beat, or even the feeling of your heart fluttering. You may also feel exhausted. The fluttering may be more apparent when you exercise or consume certain foods or drinks. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs. If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If you have frequent PVCs, your doctor might recommend that you avoid certain drinks and foods, like caffeine and alcohol. You can also take steps to lessen your stress levels, and make sure you get enough sleep and exercise. If you have many PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It destroys the cells that cause them. The procedure is carried out by a specialist known as an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms but it doesn't stop them from recurring in the future. In certain cases it may increase your risk of atrial fibrillation (AFib), which can cause stroke. It is not common, but it can be life-threatening. Symptoms Premature ventricular contractions, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats can be harmless, however you might need to see your doctor if they are frequent or if you experience symptoms like dizziness or fatigue. The electrical signals typically begin in the sinoatrial node, located in the top right side of the heart. These signals travel down to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel blood into your lungs and return to the heart and start the next pumping cycle. But a PVC starts in a different place that is separate from the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart. When PVCs occur, the heart may appear to be skipping a beat or pounding. If you only have just a few episodes and there are no other symptoms, your cardiologist will probably not treat you. If you have many PVCs the doctor may recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. They might also recommend wearing a Holter monitor that records your heartbeat over time, allowing you to see how many PVCs you have. double glazing doctor who has suffered a previous heart attack or cardiomyopathy – a condition which affects the method by which the heart pumps blood – should take their PVCs very seriously and consult a cardiologist regarding lifestyle modifications. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat. If you have frequent PVCs, even if you don't have any other signs, you should see a cardiologist. These heartbeats that are irregular can indicate an issue with the structure of your heart or to other health conditions and, over time, when they happen frequently enough, they may weaken the heart muscle. The majority of people with PVCs do not experience any issues. They just want to be aware that the fluttering or racing heartbeats aren't normal. Diagnosis PVCs may be felt as fluttering or skipped heartbeats, especially if they are frequent or intense. People who experience a lot of them might feel like they're about to faint. Exercise can trigger PVCs, but a lot of athletes who experience them do not have heart or health issues. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to study the heart and determine how it's working. Often, a doctor will be able to identify if a person is suffering from PVCs through a medical history and physical examination. Sometimes, however, they may only be able to detect PVCs when they examine the patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They can be used to identify cardiac problems in the event of any reason to be concerned. If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment needed. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine, and over the prescription decongestants, as well as the reduction of stress could aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medications that may be able to control the symptoms. Treatment If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If you experience them frequently, your doctor may want to look for other heart issues and recommend lifestyle changes or medicine. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them. If you have PVCs, the electrical signal that triggers your heartbeat is generated from a place different than the sinoatrial nerve (SA node) located in the upper right part of your heart. It can feel like your heart skips a beat or has extra beats. PVCs are more prevalent among people with heart problems however, it's not clear what causes them. PVCs may increase in frequency as you age, and may occur more frequently during exercising. If a patient is experiencing frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely perform an exercise stress test in order to determine if the additional heartbeats are related to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes of the additional beats. Most people with PVCs do not experience any problems and can enjoy a normal lifestyle. However, they may increase your risk of having dangerous heart rhythm problems, especially if you have certain patterns of them. In some instances, this means the heart muscle gets weaker and is having difficulty pumping blood throughout your body. A regular, healthy diet and plenty of exercise can help reduce your chances of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. It is also important to get enough sleep and reduce stress. Certain medicines can also increase the risk of getting PVCs. If you're taking one of these medicines it's crucial to follow your doctor's recommendations 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), a higher rate arrhythmia-induced cardiac myopathy was discovered. Some patients may require an organ transplant.
