Learn What Pvc Doctor Tricks The Celebs Are Using
How a VC Can Affect Your Heart

Many people experience occasional PVCs with no problems. If they happen frequently, PVCs may weaken your heart and increase the chance of suffering from heart failure.

The rhythm of your heart is controlled by a group of fibers that are located in the upper right-hand part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower chambers of your heart or ventricles.

Causes

PVCs happen when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different area of your heart--the ventricles--and causes an untimed beat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It could feel as if the heart skipped a beat or feels fluttering. They may occur infrequently and not cause any symptoms, but they can occur frequently enough to impact your quality of living. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor could treat them with medicine.

PVCs are generally harmless and don't increase your risk of developing heart disease. A lot of PVCs, however, can weaken the heart muscle over time. This is especially the case if they are caused by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

The symptoms of PVCs include a feeling that your heart beats faster or is fluttering, and you feel breathless. The fluttering can be more noticeable when you exercise or consume certain drinks or foods. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Some medications, such as digoxin, amiodarone, and cocaine, can increase the risk.

If you are experiencing occasional PVCs, your doctor may recommend lifestyle changes and medicines. If you experience frequent PVCs, your doctor might recommend that you avoid certain drinks and foods, like caffeine and alcohol. You can also reduce your stress, and get plenty of sleep and exercise.

If you're suffering from a lot of PVCs The doctor 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 known as an electrophysiologist. The treatment is generally successful in treating PVCs which reduce symptoms, but does not prevent them from returning in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can lead to stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, may make your heart appear to skip or flutter the beat. These heartbeats can be harmless, but you should consult your physician when you experience frequent episodes or signs like dizziness or weakness.

Normally, electrical signals start at the sinoatrial junction, located in the upper right side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to propel blood into the lungs, and return to the heart and start the next cycle of pumping. But a PVC starts in a different place, 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've experienced a few episodes and no other symptoms, your doctor will probably not treat you. But if you have a large number of PVCs, the doctor may suggest an electrocardiogram, or ECG to determine your heartbeat over the course of 24 hours. The doctor may also recommend wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs.

If you've had an earlier heart attack or cardiomyopathy - a condition which affects the heart's blood flow - should take their PVCs seriously and consult an expert in cardiology about lifestyle modifications. windowdoctor includes avoiding alcohol, caffeine and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs, even if you do not have any other signs, you should see a cardiologist. These irregular heartbeats could be a sign of problems with the structure of your heart or other health conditions and, over time when they are frequent enough, they may weaken the heart muscle. Most people who suffer from PVCs don't experience any issues. They just want to know that the fluttering or racing heartbeats aren't normal.


Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, particularly when they're frequent or intense. People who experience them regularly may feel faint. Exercise can cause them, but most athletes who suffer from them have no heart or health problems. PVCs may show up on tests such as an electrocardiogram or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.

A doctor can often tell whether a patient has 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 are able to detect PVCs, as well as other arrhythmias. They are able to detect cardiac disease in the event of any concern.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. However, if your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress can aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If the symptoms persist or are severe, speak to your doctor about treatments that could help control them.

Treatment

If PVCs aren't common or don't cause symptoms, they do not usually require treatment. If they occur frequently, your doctor might be able to look for heart conditions or recommend lifestyle adjustments. You might also get an operation to rid yourself of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can cause your heart to feel like it skips a beating or has extra beats. They're more common among people with heart problems, but it's not known the reason behind them. PVCs are more likely to occur as you age, and they may be more frequent during exercises.

A doctor should conduct an ECG and an echocardiogram on a patient that 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 due to physical exercise. To find out whether there are any other causes for the extra beats an invasive heart catheterization or a cardiac MRI is possible.

The majority of people with PVCs do not suffer from any problems and can enjoy an ordinary life. They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some instances, this means the heart muscle gets weaker and has trouble pumping blood throughout your body.

Regular exercise and a balanced diet can lower the chances of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of tobacco and caffeine. Also, you should try to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you take any of these medications, it is important that you follow your doctor's recommendations about eating healthy and exercising as well as taking your medication.

Studies of patients suffering from a high burden of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. Some people may need a heart transplant.
