How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by a variety of people without causing any issues. If they are frequent, PVCs may weaken your heart and increase your 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 corner of your heart. This is called the sinoatrial node or SA. Electrical signals travel to the ventricles or lower chambers of your heart.
Causes
PVCs occur when the electrical impulse which normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. the glass doctor impulse actually begins in the ventricles and causes a mistimed heartbeat. These extra beats, called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or is like it is fluttering. They can occur rarely without causing any symptoms, but they could be frequent enough to impact your quality of living. Your doctor might prescribe medication if they are frequent or cause dizziness, weakness or fatigue.
For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. In time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.
The symptoms of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering could be more apparent when you exercise or have certain drinks or food items. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, may increase the risk.
If you experience occasional PVCs Your glazing doctor may recommend lifestyle changes and medicines. If you have frequent PVCs, your physician may suggest that you stay away from certain foods and drinks such as caffeine and alcohol. You can also reduce your stress by getting enough sleep and exercising.
If you have a lot of PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. The procedure is carried out by a specialist known as an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms however, it doesn't prevent them from recurring in the future. In some instances it can increase your risk of having atrial fibrillation (AFib) which could result in stroke. It's not common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs, can cause your heart appear to skip or flutter the beat. These extra heartbeats can be harmless, but you may need to see your doctor if they are frequent or if you experience symptoms like dizziness or fatigue.
The electrical signals typically begin at the sinoatrial junction, located in the top right side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles contract to pump blood into the lung. They return to the heart's center to begin the next cycle of pumping. A pvc doctor - click through the next page - begins in a different place that is the Purkinje fibres bundle in the left side of the heart.
When PVCs happen they can make the heart appear to be skipping a beat or pounding. If you've experienced just a few episodes but no other symptoms, the cardiologist probably won't treat you. However, if you have number of PVCs the doctor may recommend an electrocardiogram, or ECG, to measure your heartbeat over the course of 24 hours. He or she may also recommend wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see how many PVCs you have.
If you've had a prior heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood -- should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. This includes avoiding alcohol, caffeine and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist may also prescribe medication to slow the heartbeat, for example, a beta blocker.
Even if there aren't any other symptoms however, you should have PVCs examined by an cardiologist if they occur often. These extra heartbeats may indicate a problem in the structure of your lungs or heart, and if they occur often enough, can weaken the heart muscle. But the majority of people suffering from PVCs do not experience any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.
Diagnosis
PVCs may appear to be fluttering or skip heartbeats, especially if they are frequent or intense. People who experience them regularly might feel faint. Exercise can cause them, but most athletes who experience these symptoms do not have heart or health problems. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical signals from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.
Often, a doctor will be able to identify if the patient is suffering from PVCs from a patient's history and physical exam. Sometimes, however, they may not be aware of PVCs until they examine patients for a different reason, such as after an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They may be used to detect heart disease when there is a concern.
If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. However, if your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress can aid. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can decrease the likelihood of PVCs. If the symptoms persist or are severe, speak with your physician about possible medication options to treat these symptoms.
Treatment
If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If you are frequently affected, your doctor may want to examine for other heart conditions and suggest lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.
If you have PVCs the electrical signal that triggers your heartbeat begins somewhere other than the sinoatrial node (SA node) located in the upper right side of your heart. This can make it feel like your heart skips a beat or is beating faster. They're more common among people who suffer from heart issues however, it's not clear what causes them. PVCs can become more frequent as you age, and they could be more frequent during exercising.
A physician should perform an ECG as well as an echocardiogram for a patient who suffers from frequent and painful PVCs to rule out structural heart diseases. They will probably also do an exercise stress test to determine whether the additional beats are a result of physical exercise. To find out if there are other causes for the increased beats the heart catheterization or an MRI is possible.
Most people who suffer from PVCs don't experience any issues and can live a normal lifestyle. But they can increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout your body.
A healthy, regular diet and regular exercise can help reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium, and limit your consumption of tobacco and caffeine. Sleep and stress are equally important. Certain medications can increase the risk of developing PVCs. If you are taking any of these medicines it is crucial that you follow your doctor's advice about eating healthy, exercising, and taking your medication.
Studies of patients suffering from an excessive amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Some patients may require a heart transplant.
