Why Everyone Is Talking About Pvc Doctor Right Now > 자유게시판

How a VC Can Affect Your Heart

PVCs are common and may be experienced by many people without causing any issues. If they occur often, PVCs may weaken your heart and increase the risk of heart failure.

A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial, or SA, node) typically regulates your heart's rhythm. Electrical signals travel from this node to the lower heart chambers, or ventricles.

Causes

PVCs occur when the electrical impulse which normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different part of your heart--the ventricles--and causes a wrongly timed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beat or feels fluttering. They may happen rarely and not cause any symptoms, or they may occur frequently enough to affect your quality of life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor could treat them with medicine.

PVCs are generally harmless and do not increase the risk of heart disease. Regular PVCs however, may weaken your heart muscle over time. This is particularly true if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure.

The symptoms of PVCs include feeling like your heart skips a beat or flutters, and you may feel breathless. The fluttering may be more noticeable when you exercise or consume certain drinks or foods. People who experience chronic stress or anxiety can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine may increase the chance of developing them.

If you are experiencing occasional PVCs Your doctor insulated low-e window repair repair (click through the next page) may suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to avoid some drinks and foods like caffeine and alcohol. You can also reduce your stress, and take advantage of plenty of rest and exercise.

If you have a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who execute this procedure. It is typically 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 the risk of atrial fibrillation (AFib), an illness that can result in stroke. It is not common, but it could be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, may make your heart seem to flutter or skip a beat. These extra heartbeats are generally harmless, but you should talk to your doctor if you have frequent episodes or signs like dizziness or weakness.

Normally, electrical signals begin at the sinoatrial junction, located in the top right side of the heart. These signals travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to force blood into the lungs. They return to the heart's center to start the next cycle of pumping. A PVC starts in a different place, the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs occur, they make the heart pound or feel as if it skipped one beat. If you've experienced only a few episodes, but no other symptoms, the doctor will probably not treat you. But if you have a large number of PVCs the doctor may suggest an electrocardiogram, or ECG to gauge the heart's rate over 24 hours. They may also recommend wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

If you've had an earlier heart attack or cardiomyopathy - an illness that affects the way the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle modifications. This includes avoiding alcohol, caffeine and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other indications it is still recommended to have PVCs checked by an expert in cardiology if they occur often. These extra heartbeats may signal a problem with the structure of your heart or lungs and if they occur often enough, they can weaken your heart muscle. But the majority of people suffering from PVCs do not experience any issues. They simply want to know that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, especially if they are frequent or intense. People who experience them regularly may 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 such as an electrocardiogram (ECG) or Holter monitor. They use sticky patches with sensors on them to record electrical signals from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to study the heart and determine how it's working.

A doctor is often able to tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes, however, they may only be able to detect PVCs when they examine patients for a different reason, like following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect heart disease if there is any concerns.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as decreasing stress can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms persist or are severe, talk to your doctor about treatments that could help control them.

Treatment

If PVCs aren't causing symptoms or occur rarely they aren't usually in need of treatment. If they are frequent your doctor may be able to look for heart conditions or recommend lifestyle modifications. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node that is located in the upper right corner of your heart. This can make it feel like your heart skips beats or has a few extra beats. PVCs are more prevalent among people suffering from heart disease however it's unclear what causes them. PVCs are more frequent as you age, and may occur more frequently during exercising.

If a patient experiences frequent and painful PVCs doctors should perform an ECG and an echocardiogram to rule out structural heart disease. They will probably also do an exercise stress test to determine whether the extra beats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be performed to find other causes for the extra beats.

The majority of people who suffer from PVCs are not affected and can live 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 instances, this means that the heart muscle gets weaker and is unable to pump blood throughout your body.

A healthy and balanced diet and plenty of exercise can reduce the risk of developing PVCs. You should avoid foods that are high in sodium and fat as well as restrict your intake of tobacco and caffeine. Sleep and stress are equally crucial. Certain medicines can also increase your risk of getting PVCs. If you take any of these medications, it is important that you follow your doctor's advice regarding eating a healthy diet and exercising as well as taking your medication.

In studies of patients suffering from high PVC burdens (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. Some patients may require a heart transplant.
