The Most Popular Pvc Doctor It's What Gurus Do Three Things
How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) typically controls the heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers or ventricles.

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 impulse actually begins in the ventricles, causing an irregular heartbeat. These extra beats, called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or is like it is fluttering. They may occur infrequently without causing any symptoms, but they may be frequent enough to affect your standard of life. Your doctor might prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.

PVCs can cause symptoms like a feeling of your heart racing a beat, or the feeling of your heart fluttering. window doctor is also possible to feel breathless. The fluttering can be more noticeable if you exercise, or consume certain drinks or foods. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Some drugs, like digoxin, amiodarone and cocaine, can also increase their risk.

If you have occasional PVCs Your doctor might suggest lifestyle changes and medication. If they're a frequent occurrence, you may need to avoid some foods and beverages like alcohol and caffeine. You can also take steps to reduce your stress, and make sure you get enough sleep and exercise.

If you're experiencing lots of PVCs, he may suggest a medical procedure called radiofrequency catheter ablation. This destroys cells that cause PVCs. This procedure is performed by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs which reduce symptoms, but does not prevent them from returning in the future. In some cases it may increase your risk of having atrial fibrillation (AFib), which can cause stroke. It's not common, but it can be life-threatening.


Symptoms

Premature ventricular contractions or PVCs, may make your heart seem to flutter or skip the beat. These extra heartbeats are generally harmless, but you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

The electrical signals normally begin in the sinoatrial region, which is in the upper right part of the heart. They then travel to the lower chambers, or ventricles, that pump blood. The ventricles expand to push blood into your lungs and then return to your heart to start the next cycle of pumping. A PVC starts in a different place in the Purkinje fibres bundle at the left-hand side of the heart.

When PVCs happen they can make the heart feel as if it's racing or pounding. If you experience only a few episodes, and no other symptoms are present your cardiologist may not prescribe treatment. If you've got a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. They may 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 suffered a previous heart attack or cardiomyopathy, a condition which affects the way the heart pumps blood - should take their PVCs very seriously and speak to an expert in cardiology about lifestyle modifications. These include abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

Even if you don't experience any other indications it is still recommended to have PVCs checked by a cardiologist if they happen often. These extra heartbeats may indicate a problem in the structure of your lungs or heart, and if they occur frequently enough, can weaken your heart muscle. However, most 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 might be felt as fluttering or skipped heartbeats, especially if they're intense or frequent. People who get lots of them may feel they're going to faint. They can also occur during exercise, though many athletes who get them don't have any problems with their health or heart. PVCs may show up in tests like an electrocardiogram or Holter monitor. These use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to study the heart and observe how it's working.

A doctor is often able to tell the presence of PVCs by examining them and taking their medical history. However, sometimes they will only be able to detect them when they examine the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitoring systems also assist in detecting 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 normal, reassurance will be the only treatment needed. However, if your symptoms are causing discomfort or make you feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medication that could be able to reduce them.

Treatment

If PVCs aren't causing symptoms or happen rarely they aren't usually in need of treatment. If they are frequent your doctor may be able to look for heart issues or suggest lifestyle changes. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs The electrical signal that triggers your heartbeat is generated from a place different than the sinoatrial nerve (SA node) in the top right corner of your heart. It can feel like your heart skips a beat or has extra beats. PVCs are more frequent among those suffering from heart disease however it's unclear the reason behind them. PVCs may increase in frequency as we age and can occur more frequently during exercising.

A physician should perform an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to rule out structural heart diseases. The doctor will also perform an exercise stress test to determine if the extra heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other reasons for the additional beats.

The majority of people with PVCs do not experience any complications and can lead an ordinary life. But they can increase the risk of developing dangerous heart rhythm issues particularly 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 the body.

Regular exercise and a balanced diet can reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Also, you should try to get enough rest and reduce stress. Certain medications can increase the risk of getting PVCs. If you are taking one of these medicines it's crucial to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

Studies of patients with an excessive amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. This could lead to the need for a heart transplant in some individuals.
