How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by a wide range of people without causing any problems. If they happen frequently, PVCs may weaken your heart and increase your risk of heart failure.
A bundle of fibers in the upper right part of your heart (the sinoatrial, or SA, node) usually controls your heart rhythm. Electrical signals are transmitted to the ventricles or lower chambers of your heart.
Causes
PVCs are caused when the electrical impulse that typically initiates your heartbeat at a point called the sinus node (also called the sinoatrial or SA Node) does not. The impulse actually starts in the ventricles and causes a mistimed heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It may feel like the heart skipped a beating or feels fluttering. They may happen rarely and not cause any symptoms, or they can happen often enough to interfere with your daily life. If they happen frequently or cause dizziness, weakness or fatigue, your pvc doctor could treat them with medication.
For the majority of people, PVCs are harmless and do not increase the risk of developing 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-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.
PVCs can cause symptoms, such as a sensation of your heart beating one beat, or even the feeling of your heart fluttering. You might also feel breathless. The fluttering could be more noticeable when you exercise or have certain drinks or foods. PVCs are more common in people with chronic anxiety or stress. Certain medications, such as digoxin, amiodarone and cocaine, can also increase their risk.
If you have occasional PVCs, your doctor may suggest lifestyle changes and medications. If they are a regular occurrence, you may need to avoid certain drinks and foods, such as alcohol and caffeine. You can also lessen your stress levels by having enough sleep and exercising.
If you're suffering from lots of PVCs The doctor may suggest a medical procedure called radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. This is done by a specialist called an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, however it does not stop them from recurring in the future. In some cases it can increase your risk of having atrial fibrillation (AFib), which can cause a stroke. It's not common, but it can be life-threatening.
Symptoms
Premature ventricular contractions, also known as PVCs, can cause your heart seem to skip or flutter one beat. These extra heartbeats are usually harmless, however, you should consult your physician if you have frequent episodes or signs like dizziness or weakness.
Normally, electrical signals start in the sinoatrial node located in the upper right portion of the heart. They move down to the lower chambers (or ventricles) which pump blood. The ventricles expand to push the blood into the lung. They then return to the center to start the next cycle of pumping. But a pvc Doctor begins at a different spot and is located in the bundle of fibers known as the Purkinje fibers, in the left-hand side of the heart.
When PVCs occur, they cause the heart beat or feel like it skipped the beat. If you have only a few episodes, and there are no other symptoms, your cardiologist will probably not be able to treat you. If you've got a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over the course of 24 hours. He or she might also recommend wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see the number of PVCs you have.
People who have had a previous heart attack or have cardiomyopathy -an illness that affects the way that the heart pumps blood must be aware of their PVCs and talk to a cardiologist about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.
If you have frequent PVCs even if you do not have any other symptoms, you should consult an expert in cardiology. These heartbeats that are irregular could signal a problem with the structure of your heart or lungs, and if they occur frequently enough, they can weaken your heart muscle. However, most people suffering from PVCs don't experience any problems. They simply want to be aware that the fluttering and skipping heartbeats aren't normal.
Diagnosis
PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them may feel they're going to faint. Exercise can trigger them, but most athletes who experience these symptoms do not have heart or health problems. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.
Often, a doctor will be able to identify if the patient is suffering from PVCs from a history and physical examination. However, sometimes they will only notice them while examining the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and could be utilized when there is a concern of heart disease.
If your cardiologist concludes that your heart is structurally normal, reassurance will be the only treatment required. However, if your symptoms are bothersome or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may help. Regular exercise, maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your window doctor about medication that could help control these symptoms.
Treatment
If PVCs do not cause any symptoms or occur rarely they aren't usually in need of treatment. If they are frequent, your doctor might want to check for heart problems or suggest lifestyle changes. You may also undergo an operation (called radiofrequency cathode ablation) to get rid of them.
If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located outside of 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 a beating or has extra beats. It's not clear what causes them, but they're more common in people with other heart problems. PVCs may increase in frequency as you age, and may be more frequent during exercise.
If a patient experiences frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. They should also conduct an exercise stress test to see whether the additional beats are a result of physical activity. To find out whether there are other reasons for the extra beatings an invasive heart catheterization or an MRI can be performed.
Most people who suffer from PVCs have no complications and can lead a normal life. They can increase the risk of heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some cases, that means that the heart muscle becomes weaker and has trouble pumping blood through your body.
A regular, healthy diet and a lot of exercise can help reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of tobacco and caffeine. Stress and sleep are also important. Certain medications can increase the risk of developing PVCs. If you take any of these medications it is essential that you follow the advice of your doctor about eating healthy, exercising, and taking your medication.
Studies of patients with an excessive amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
