How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a variety of people with no cause for concern. If they are frequent, PVCs may weaken your heart and increase your risk for heart failure.

A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) 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 which normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or fit SA node) is not initiated. The impulse actually begins in the ventricles, which causes a mistimed heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. They may feel like the heart beats faster or feels fluttering. They can happen infrequently and not cause any symptoms, or they can occur frequently enough to affect your quality of life. If they occur frequently 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, could weaken your heart muscle over time. This is especially relevant if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

PVCs can cause symptoms like a feeling of your heart racing an beat, or fluttering. It is also possible to feel exhausted. The fluttering may be more apparent when you exercise or have certain foods or drinks. PVCs are more common in people with chronic anxiety or stress. Certain medications, like digoxin, amiodarone and cocaine, may increase the risk of developing PVCs.

If you are experiencing occasional PVCs, Modern window repair your doctor sliding window Repair may recommend lifestyle changes and medicines. If you have frequent PVCs, your physician may suggest that you stay away from certain drinks and Dormer window repair foods, like caffeine and alcohol. You can also take steps to reduce your stress and take advantage of plenty of rest and exercise.

If you're experiencing lots of PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation. This destroys cells that cause PVCs. The procedure is carried out by a specialist known as an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib), which can lead to a stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, can make your heart seem to flutter or skip one beat. These extra heartbeats are generally harmless, but it is important to consult your physician in case you experience frequent episodes or other symptoms such as dizziness or weakness.

The electrical signals normally begin in the sinoatrial area, which is located 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 the blood into the lung. They return to the heart's center to start the next cycle of pumping. A PVC starts in a different location that is the Purkinje fibers are located in the left side of the heart.

When PVCs occur, they cause the heart beat faster or feel as if it skipped one beat. If you have only one or two episodes, and there are no other symptoms your cardiologist may not treat you. If you've got a large number of PVCs, the doctor may recommend an electrocardiogram, energy-efficient window repair or ECG to determine your heart rate over 24 hours. They may also recommend wearing a Holter monitor that records the heart's rhythm over time to see the number of PVCs you have.

If you've had a previous heart attack or cardiomyopathy - an illness that affects 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, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medication to slow heartbeat, like beta blockers.

Even if you don't have any other indications however, you should have PVCs checked 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 happen often enough, it could weaken the heart muscle. But most people suffering from PVCs don't experience any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, especially if they're intense or frequent. People who experience them regularly may feel faint. They can also happen with training, even though many athletes who experience them don't have any problems with their health or heart. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to look at the heart and see how it's functioning.

Most of the time, a doctor will be able to identify if a person has PVCs through a medical history and physical examination. Sometimes, they may not be aware of them until they examine the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias and could be utilized when there is a concern of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress may aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also help reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible medications that can control the symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually require treatment. If they happen frequently, your doctor might want to check for heart problems or suggest lifestyle modifications. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or is beating faster. PVCs are more frequent among those with heart problems however, it's not clear what causes them. PVCs can increase in frequency with age and might happen more frequently during exercise.

If a patient has frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to determine if the extra beats are caused by physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be performed to find other reasons for the additional beats.

Most people who suffer from PVCs have no complications and can lead 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 healthy and balanced diet and a lot of exercise can reduce the 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. Sleep and stress are also crucial. Certain medicines can also increase the risk of developing PVCs. If you take any of these medicines it is essential to follow your doctor's recommendations regarding healthy eating exercising, as well as taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. This can result in a need for a heart transplant in some patients.
