How a VC Can Affect Your Heart

Many people experience occasional PVCs and have no issues. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is controlled by a group of fibers located in the upper right-hand part of your heart. This is known as the sinoatrial node or SA. Electrical signals are transmitted to the lower heart chambers or ventricles.

Causes

PVCs occur when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. Instead, the window doctor impulse begins in another area of your heart, the ventricles, and causes an untimed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat, or it feels like it is fluttering. They can happen infrequently and not cause any symptoms, or they can happen often enough to interfere with your quality of life. If they are very frequent or cause dizziness, weakness, or fatigue, your doctor might treat them with medication.

For most 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 particularly relevant if they are triggered by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.

The symptoms of PVCs include a feeling that your heart beats faster or it flutters. You may feel breathless. The fluttering may be more noticeable when you exercise or consume certain foods or beverages. PVCs are more prevalent in people with chronic anxiety or stress. Some medications, like digoxin, amiodarone or cocaine, can also increase their risk.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medications. If you have frequent PVCs, your doctor may recommend that you avoid certain drinks and foods, like caffeine and alcohol. You can also lessen your stress levels by taking enough rest and exercising.

If you've got a lot of PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who execute this procedure. The treatment is generally successful in treating PVCs which reduce symptoms, but it does not stop them from returning in the future. In some instances it may increase your risk of atrial fibrillation (AFib), which can lead to a stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or to flutter. These extra heartbeats are generally harmless, but you should consult your physician if you have frequent episodes or signs like dizziness or weakness.

Normally, electrical signals begin in the sinoatrial node located in the upper right side of the heart, and move down to the lower chambers (or ventricles) that pump blood. The ventricles expand to force blood into the lung. They return to the center to start the next cycle of pumping. However, a PVC starts in a different location, from the bundle of fibers called the Purkinje fibers, located in the bottom left portion of the heart.

When PVCs happen, the heart may feel like it is beating faster or slower. If you experience only a few episodes, but no other symptoms, your cardiologist probably won't treat you. If you've got a large number of PVCs, the doctor may suggest an electrocardiogram, or ECG to determine the heart's rate over the course of 24 hours. He or she might also recommend wearing a Holter monitor, which will record the heart's rhythm over time, allowing you to see the number of PVCs you have.

If you've had a prior heart attack or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood -- should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and getting enough rest. A cardiologist can also prescribe medication to slow the heartbeat such as beta blockers.

If you are experiencing frequent PVCs, even if you don't have any other signs, you should see an expert in cardiology. These extra heartbeats may signal a problem with the structure of your heart or lungs and if they occur often enough, they can weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They just want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them frequently may feel faint. They can also happen with exercise, though many athletes who suffer from them do not have any issues with their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist might also use an echocardiogram that uses ultrasound to examine the heart and see how it's functioning.

A doctor will usually be able to determine if a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes however, they might not be aware of PVCs until they examine patients for a different reason, such as after an accident or surgery. 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 determines that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are causing you discomfort or cause you to feel anxious, avoiding alcohol, caffeine and over-the prescription decongestants, as well as reducing stress may help. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible treatments that could help control the symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually need treatment. If they occur frequently, your doctor might be able to look for heart conditions or recommend lifestyle modifications. You may also undergo an operation (called radiofrequency cathode ablation) to get rid of them.

When you have PVCs, the electrical signal that causes your heartbeat starts somewhere outside of the sinoatrial node (SA node) in the top right side of your heart. This could cause your heart to feel like it skips beats or has additional beats. It's not known what causes these symptoms, but they're common in people who have other heart problems. PVCs can become more frequent as you age, and may be more frequent during exercise.

If a patient is experiencing frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor may also perform an exercise stress test in order to determine if the increased heartbeats are caused by physical activity. To determine if there are other causes for the increased beats the heart catheterization or an MRI is possible.

Most people with PVCs do not experience any complications and can lead a normal lifestyle. However, they can increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout your body.

A healthy, regular diet and regular exercise can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium and limit your intake of tobacco and caffeine. Sleep and stress are also important. Certain medicines can also increase your risk of PVCs. If you are taking one of these drugs, it's important to follow the doctor's advice about eating well, exercising and taking your medication.

In studies of patients with pvc doctor (just click the following article) burdens that are high (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Certain people may require a heart transplant.
