How a VC Can Affect Your Heart

PVCs are common and may be experienced by a variety of people without causing any issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

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

Causes

PVCs happen when the electrical impulse that normally starts your heartbeat in a region called the sinus node (also known as the sinoatrial or SA Node) does not. Instead, the impulse is generated in a different area of your heart--the ventricles--and causes an untimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart skipped a beat or feels fluttering. They can occur rarely, causing no symptoms, but they could be frequent enough to impact your quality of life. If they happen frequently or cause weakness, dizziness or fatigue, your doctor might treat them with medication.

In most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health problems. Frequent PVCs however, may weaken your heart muscle over time. This is particularly relevant if the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

The symptoms of PVCs include a feeling that your heart beats slower or it flutters. You may feel breathless. The fluttering could be more apparent when you exercise or consume certain drinks or food items. PVCs are more prevalent for those who suffer from chronic anxiety or stress. Some drugs, like digoxin, amiodarone or cocaine, can also increase the risk of developing PVCs.

If you experience occasional PVCs, your doctor may recommend lifestyle changes and medicines. If you are prone to frequent PVCs, your doctor might recommend that you avoid certain foods and drinks, such as alcohol and caffeine. You can also lessen your stress levels by getting enough sleep and working out.

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

Signs and symptoms

Premature ventricular contractions, also known as PVCs, may make your heart seem to flutter or skip the beat. These heartbeats can be harmless, however, you should talk to your doctor when you experience frequent episodes or other symptoms such as dizziness or weakness.

The normal electrical signals start in the sinoatrial, located in the upper right-hand part of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. Then, the ventricles contract to propel blood into the lungs, and then return to your heart to start the next cycle of pumping. However, a pvc Doctor near me begins at a different spot, from the bundle of fibers known as the Purkinje fibers in the lower left part of the heart.

When PVCs happen, the heart may feel like it is beating faster or slower. If you have a few episodes and no other symptoms, your doctor will probably not treat you. If you've got a number of PVCs, the window & door doctor may recommend an electrocardiogram, or ECG, to measure your heart rate over the course of 24 hours. He or she might also suggest wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

Anyone who has suffered a heart attack in the past or have cardiomyopathy -which affects the way that the heart pumps blood- should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, and getting enough rest. A cardiologist may prescribe medication to slow the heartbeat, like beta blockers.

If you have frequent PVCs even if do not have other signs, you should see an expert in cardiology. These heartbeats that are irregular could indicate a problem in the structure of your heart or lungs, and if they happen often enough, they can weaken your heart muscle. However, most people suffering from PVCs don't have any issues. They simply want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that flutter, especially if they are frequent and intense. People who experience them often may feel faint. Exercise can trigger them, but most athletes who suffer from these symptoms do not have heart or health issues. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors on them to record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's working.

A doctor may be able to identify if a person has PVCs from a history and physical examination. But sometimes they might not be aware of them until they examine the patient for other reasons, such as after a surgery or accident. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect cardiac disease in the event of any concerns.

If your cardiologist determines your heart is structurally healthy, reassurance may be all that's needed. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress can help. 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, talk to your physician about the medications that could be able to control them.

Treatment

If PVCs do not cause any symptoms or are not frequent generally, they don't require treatment. If they are frequent your doctor may be able to look for heart problems or suggest lifestyle changes. You may also undergo an operation (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located outside of the sinoatrial (SA) node located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips beats or is beating faster. They're more common among people suffering from heart disease however, it's not clear the reason behind them. PVCs may increase in frequency as we age and can occur more often during exercises.

If a patient experiences frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other reasons for the additional beats.

Most people who suffer from PVCs do not experience any problems and can enjoy a normal lifestyle. They could increase the risk of developing heart rhythm disorders that can be dangerous particularly if they happen 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 plenty of exercise can help reduce your risk of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of tobacco and caffeine. Sleep and stress are equally crucial. Certain medicines can also increase the risk of getting PVCs. If you take any of these medications it is crucial that you follow your doctor's recommendations about eating healthy exercising, as well as taking your medication.

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