How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial, or SA, node) usually controls your heart's rhythm. Electrical signals are transmitted from there to the lower chambers of your heart, or ventricles.

Causes

PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, which causes an irregular heartbeat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart beats faster or feels like it is fluttering. They can happen infrequently and not cause any symptoms, or they can occur frequently enough to impact your daily life. If they are very frequent or cause weakness, dizziness, or fatigue, your window & door doctor may treat them with medication.

For the majority of people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Frequent PVCs, however, can weaken your heart muscle over time. 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.

PVCs can cause symptoms, such as a sensation of your heart racing a beat, or the feeling of your heart fluttering. You might also feel breathless. The fluttering could be more apparent when you exercise or have certain drinks or foods. PVCs are more prevalent in those suffering from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone or cocaine, may increase the risk of developing PVCs.

If you are experiencing occasional PVCs, your doctor may suggest lifestyle changes and medications. If they are a regular occurrence, you may have to avoid some drinks and foods, such as alcohol and caffeine. You can also take steps to lessen your stress, and make sure you get enough sleep and exercise.

If you're suffering from many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation, which destroys the cells that are responsible for PVCs. This procedure is performed by a specialist called an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), which can cause stroke. This is rare but can be life-threatening.

Signs and symptoms

Premature ventricular contracts, or PVCs can cause your heart to skip or flutter. These extra heartbeats are usually harmless, but you should consult your physician if you have frequent episodes or other symptoms such as dizziness or weakness.

Normally, electrical signals begin in the sinoatrial node, which is in the top right portion of the heart, and descend to the lower chambers (or ventricles) which pump blood. The ventricles then contract to pump blood into the lung. They then return to the center to begin the next cycle of pumping. But a pvc Doctor begins in a different location that is separate from the bundle of fibers known as the Purkinje fibers, in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel as if it's racing or pounding. If you experience only just a few episodes and there are no other symptoms, your cardiologist will probably not be able to treat you. But if you have a number of PVCs and you have other symptoms, your upvc window doctor might recommend an electrocardiogram, or ECG to determine the heart's rate over the course of 24 hours. He or she might also recommend wearing a Holter monitor that will track the heart's rhythm over time to determine the number of PVCs you have.

People who have suffered a heart attack in the past or have cardiomyopathy -which alters the way the heart pumps blood should take their PVCs seriously and consult a cardiologist about lifestyle changes. This includes the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.

Even if you don't have any other symptoms however, you should have PVCs examined by an cardiologist if they occur often. These irregular heartbeats could signal a problem with the structure of your heart or lungs, and if they occur frequently enough, they can weaken the heart muscle. The majority of people with PVCs do not experience any issues. They just want to know that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering, especially if they are frequent and intense. People who experience them regularly might feel faint. They can also happen with training, even though many athletes who experience them do not have any issues in their heart or health. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to study the heart and see how it's functioning.

A doctor can often tell whether a patient has PVCs by examining them and taking their medical history. Sometimes however, they might only notice PVCs when examining patients for a different reason such as following an accident or surgery. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and can be used when there is a concern of a cardiac condition.

If your cardiologist concludes that your heart is structurally healthy, reassurance might be all you need. If your symptoms are causing you discomfort 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 all help reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible treatments that could help control the symptoms.

Treatment

If PVCs are rare or do not cause symptoms, they rarely need treatment. If they happen frequently, your windows doctor might want to check for heart problems or suggest lifestyle modifications. You could also have a procedure (called radiofrequency cathode ablation) to eliminate them.

When you have PVCs the electrical signal that triggers your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right part of your heart. This can cause your heart to feel like it skips a beating or has extra beats. PVCs are more frequent among those suffering from heart disease however it's unclear the reason behind them. PVCs can become more frequent as you age, and might occur more frequently during exercising.

A doctor windows should conduct an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to identify structural heart conditions. The doctor may also conduct an exercise stress test to determine if the extra heartbeats are caused by physical exercise. To find out whether there are other reasons for the extra beats, a heart catheterization or cardiac MRI can be performed.

Most people with PVCs don't experience any issues and can live an ordinary life. But they can increase the risk of developing dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some instances, this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

Regular exercise and a balanced diet will lower the risk of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of caffeine and tobacco. Sleep and stress are equally important. Certain medicines can also increase your risk for PVCs. If you are taking one of these medicines it's crucial to follow your doctor's recommendations about eating well, exercising and taking your medication.

Studies of patients with a high amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. This can result in the need for a transplant in a few people.
