How a VC Can Affect Your Heart

Many people have occasional PVCs with no problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers in the upper right part of your heart (the sinoatrial or SA node) typically regulates the heart's rhythm. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that usually starts your heartbeat at a point called the sinus node (also called the sinoatrial or SA node) isn't. Instead, the impulse is generated in a different area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beat or feels fluttering. They can occur rarely, causing no symptoms, but they could be frequent enough to affect your quality of living. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor might treat them with medication.

PVCs are generally safe and do not increase your risk of heart disease. In time, repeated PVCs can weaken the heart muscle. This is particularly true if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.

The signs of PVCs include a feeling that your heart beats faster or it flutters. You may feel exhausted. The fluttering can be more noticeable when you exercise, or consume certain beverages or foods. People who suffer from chronic anxiety or stress can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine can increase the risk of developing them.

If you experience occasional PVCs, your doctor may suggest lifestyle changes and medication. If you experience frequent PVCs, your physician may recommend avoiding certain foods and drinks, like caffeine and alcohol. You can also take steps to lessen your stress, and get plenty of sleep and exercise.

If you've got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells responsible for them. The procedure is carried out by a specialist known as an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms, however, it doesn't prevent them from recurring in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can result in stroke. This is rare but it could be life-threatening.

Symptoms

Premature ventricular contractures, Window Seal Replacement or PVCs can cause your heart to skip or to flutter. These extra heartbeats are harmless, however you might need to see your doctor when they occur frequently or if you are experiencing symptoms such as dizziness or fatigue.

Normally, electrical signals start in the sinoatrial node, which is in the top right-hand side of the heart. They descend to the lower chambers (or ventricles) that pump blood. The ventricles contract to pump blood into the lungs. They return to the center to start the next cycle of pumping. However, a PVC starts in a different place and is located in the bundle of fibers called the Purkinje fibers, located in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel like it is beating faster or slower. If you experience only a few episodes, and there are no other symptoms the cardiologist will likely not treat you. If you've got a lot of PVCs, your doctor may recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. The doctor may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has suffered a heart attack in the past or have cardiomyopathy -- a condition that alters the way the heart pumps blood - must be aware of their PVCs and speak with a cardiologist about changes to their lifestyle. These include abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, and Cheaper getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you experience frequent PVCs, even if you do not have any other signs, you should see an expert in cardiology. These heartbeats that are irregular could be a sign of a problem with the structure of your lungs or heart, and if they occur often enough, can weaken the heart muscle. However, most people with PVCs don't have any issues. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, particularly when they are frequent or intense. People who experience a lot of them may feel they're about to faint. They can also happen with training, even though many athletes who suffer from them do not have any issues in their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's working.

A doctor is often able to tell the presence of PVCs by examining them and taking their medical history. But sometimes they might not be aware of them until they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias and they might be used if there's any concern of heart disease.

If your cardiologist determines that your heart's structure is normal, reassurance will be the only treatment needed. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine and over-the counter decongestants, and reducing stress may aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also decrease the likelihood of PVCs. If your symptoms continue or are severe, talk with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs don't cause symptoms or are not frequent they aren't usually in need of treatment. If they are frequent your doctor may need to examine for heart problems or suggest lifestyle changes. You could also have an intervention to get rid of them (called radiofrequency catheter ablation).

If you have PVCs the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) in the top right side of your heart. This can cause your heart to feel like it skips a beating or has extra beats. They're more common among people with heart problems however, it's not clear the reason behind them. PVCs are more likely to occur as you age, and might occur more frequently during exercise.

A doctor should perform an ECG and an echocardiogram for a patient who has frequent and painful PVCs to identify structural heart conditions. The doctor will also perform an exercise stress test in order to determine if the additional heartbeats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other causes of the additional beats.

Most people with PVCs do not have any issues and can live the normal life. They may increase the risk of heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

A regular, healthy diet and regular exercise can reduce the risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and sash window repair caffeine. Sleep and stress are also crucial. Certain medicines can also increase your risk of getting PVCs. If you're taking one of these medicines it's crucial to follow your doctor's instructions about eating well, exercising and energy-Efficient window repair taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Some patients may require an organ transplant.
