Why Pvc Doctor Is Tougher Than You Imagine
How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a variety 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) typically regulates your heart's rhythm. Electrical signals travel from there to the lower chambers of your heart or ventricles.

Causes

PVCs occur when the electrical impulse that usually initiates your heartbeat at a point called the sinus node (also called the sinoatrial or SA Node) isn't. Instead, the impulse begins in a different part of your heart, the ventricles, and causes a mistimed beat. These extra beats, also called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat, or it feels like it is like it's fluttering. They may occur infrequently and not cause any symptoms, but they may occur frequently enough to impact your quality of living. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor may treat them with medication.

For the majority of people, PVCs are harmless and don't increase your risk of heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially true if they are caused by a heart-related condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.

The symptoms of PVCs include a feeling that your heart beats slower or it flutters. You may feel exhausted. The fluttering could be more evident when you exercise or eat or drink certain beverages or foods. People who suffer from chronic anxiety or stress can have more PVCs and certain drugs like amiodarone digoxin, and cocaine may increase the risk of developing them.

If you experience occasional PVCs, your doctor may suggest lifestyle changes and medications. If they are a regular occurrence, you may need to avoid some drinks and foods, such as caffeine and alcohol. You can also lower stress by taking enough rest and exercising.

If you have lots of PVCs, he may suggest a medical treatment called radiofrequency catheter ablation, which destroys cells that cause PVCs. This is done by a specialist, known as an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib) which could lead to stroke. This is rare but it could be life-threatening.

Signs and symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are generally harmless, but you should talk to your doctor when you experience frequent episodes or signs like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node, located in the top right side of the heart. They move down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to pump blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC begins at a different spot and is located in the bundle of fibers, known as the Purkinje fibers, located in the lower left part of the heart.

When PVCs occur, the heart may feel as if it's beating faster or slower. If you have only a few episodes, and no other symptoms are present, your cardiologist will probably not be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. The doctor might also recommend wearing a Holter monitor, which will record your heart rhythm over time to determine the number of PVCs you have.

Anyone who has suffered a previous heart attack or cardiomyopathy, a condition which affects the way the heart pumps blood - must take their PVCs seriously and consult a cardiologist regarding lifestyle modifications. This includes abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and getting enough rest. A cardiologist might prescribe medications to slow heartbeat, such as beta blockers.

If you experience frequent PVCs, even if you do not have any other signs, you should see an expert in cardiology. These extra heartbeats may indicate a problem in the structure of your heart or lungs, and if they happen often enough, can weaken the heart muscle. Most people who suffer from PVCs do not experience any problems. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.


Diagnosis

PVCs can be felt as fluttering or skipped heartbeats, especially when they are frequent or intense. People who experience them often may feel weak. They can also happen with exercising, but most athletes who suffer from them don't have issues with their health or heart. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and determine how it's working.

Most of the time, a doctor will be able to tell whether someone is suffering from PVCs from a patient's history and physical exam. However, sometimes they will only be able to detect them when they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems can also aid in detecting PVCs and other arrhythmias, and can be used if there's any concern of cardiac disease.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment required. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as the reduction of stress could help. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms are persistent or severe, speak to your doctor about medication that could help manage these symptoms.

If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If they are frequent, your doctor might want to check for heart problems or suggest lifestyle modifications. You may also undergo an operation (called radiofrequency cathode ablation) to get rid them.

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. It can feel like your heart skips a beat or is beating faster. It's not known what causes these symptoms, but they're frequent in those with other heart problems. PVCs can become more frequent as you age, and might occur more frequently during exercise.

A physician should perform an ECG along with an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. The doctor may also perform an exercise stress test to determine if the additional heartbeats are caused by physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be performed to find other reasons for the increased beats.

Most people who suffer from PVCs do not have any issues and can live a normal life. They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout the body.

A regular, healthy diet and regular exercise can help reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. You should also try to get enough sleep and reduce stress. Some medicines may also increase your risk for PVCs. So if you take one of these medicines it's crucial to follow the doctor's advice about eating well, exercising and taking your medication.

Studies of patients who had a high amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Some patients may require a heart transplant.
