How a VC Can Affect Your Heart

PVCs are common and may be experienced by a wide range of people with no cause for concern. If they happen frequently, PVCs may weaken your heart and increase your risk for heart failure.

The heart's rhythm is usually controlled by a group of nerve fibers situated in the upper right part of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from there to the lower heart chambers, or ventricles.

Causes

PVCs occur when the electrical impulse that normally initiates your heartbeat in a part called the sinus node (also known as the sinoatrial node or SA node) isn't. Instead, the impulse begins in another area of your heart--the ventricles--and causes a mistimed beat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They can happen infrequently and have no symptoms or they may occur frequently enough to affect your quality of life. Your doctor may prescribe medication in the event that they are frequent or cause dizziness, weakness or fatigue.

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

PVCs can cause symptoms like a feeling of your heart racing one beat, or even fluttering. It is also possible to feel breathless. The fluttering can be more evident when you exercise, or consume certain beverages or foods. PVCs are more common in people with chronic stress or anxiety. Certain medications, like digoxin, amiodarone and cocaine, can increase their risk.

If you are experiencing occasional PVCs Your doctor may recommend lifestyle changes and medicines. If they are a regular occurrence, you may have to avoid some drinks and foods, window Caulking such as caffeine and alcohol. You can also lower stress by getting enough sleep and working out.

If you have many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. This eliminates the cells that cause PVCs. Electrophysiologists are the ones who carry out this procedure. The treatment is generally effective in treating PVCs, reducing symptoms but it does not stop them from recurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib) which is a condition that can cause stroke. It is not common however it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, may make your heart seem to flutter or skip one beat. These extra heartbeats are usually harmless, but it is important to talk to your doctor when you experience frequent episodes or other symptoms such as dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right corner of the heart. They then move to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles then contract to pump blood into the lungs. They then return to the center to begin the next cycle of pumping. But a PVC starts in a different place that is separate from the bundle of fibers, known as the Purkinje fibers, located in the left-hand side of the heart.

When PVCs occur they can make the heart appear to be racing or pounding. If you have only one or two 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, the doctor may suggest an electrocardiogram, or ECG to gauge your heart rate over the course of 24 hours. The doctor might also recommend wearing a Holter monitor that records your heart rhythm over time, allowing you to see how many PVCs you have.

Anyone who has had a prior heart attack or have cardiomyopathy -which alters the way the heart pumps blood -- must be aware of their PVCs and consult a cardiologist about lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs, even if you don't have any other symptoms, you should consult an expert in cardiology. These heartbeats that are irregular could indicate a problem in the structure of your heart or lungs, and if they occur often enough, can weaken the heart muscle. But most people with PVCs don't have any issues. They simply want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, especially if they're intense or frequent. Patients who have a lot of them may feel they're about to faint. Exercise can trigger them, but most athletes who suffer from these symptoms do not have heart or health problems. PVCs can show up on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.

Often, a doctor will be able to tell whether the patient is suffering from PVCs through a medical history and physical exam. Sometimes it is possible that they only notice PVCs when examining the patient for another reason, like following an accident or a surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect heart disease if there is any concerns.

If your cardiologist concludes that your heart is structurally healthy, reassurance may be all that's needed. However, if your symptoms are causing discomfort or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms continue or are severe, speak to your doctor about medication options to treat these symptoms.

Treatment

If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If you are frequently affected and frequently, your doctor might want to look for other heart issues and recommend lifestyle changes or medication. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial (SA) node that is located in the upper right corner of your heart. This can cause your heart to feel as if it skips beats or has additional beats. It's not known what causes them, but they're more frequent in those with other heart conditions. PVCs can become more frequent as you age, and they may be more frequent during exercising.

If a patient has frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are related to physical exercise. To find out whether there are any other causes for the extra beatings, a heart catheterization or an MRI could be conducted.

The majority of people who suffer from PVCs do not have any issues and can lead the normal life. They may increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, that means that your heart muscle gets weaker and is unable to pump blood through your body.

A healthy and balanced diet and regular exercise can reduce your risk of developing PVCs. Avoid foods high in fat and sodium and limit your intake of caffeine and tobacco. Sleep and stress are also important. Certain medicines can also increase the risk of getting PVCs. If you are taking any of these medicines it is essential to follow the advice of your doctor Hurricane-Proof Window Repair about eating healthy, exercising, Window screen Repair and taking your medication.

Studies of patients suffering from a high amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. This could lead to a need for a heart transplant in some patients.
