How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people with no cause for concern. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial node, also known as SA) typically regulates your heart rhythm. Electrical signals are transmitted from there to the lower chambers of your heart, or ventricles.

Causes

PVCs are caused when the electrical impulse that normally starts your heartbeat in a part called the sinus node (also known as the sinoatrial or SA node) does not. Instead, the impulse begins in another area of your heart, the ventricles, and causes a mistimed beat. These extra beats, called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat or is fluttering. They can happen infrequently and have no symptoms or they can happen often enough to interfere with your daily life. Your doctor might prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally safe and do not increase your risk of developing heart disease. Regular PVCs, however, can weaken your heart muscle over time. This is especially when the PVCs result from a condition like dilated cardiomyopathy and Victorian Window Repair arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.

The signs of PVCs include feeling like your heart beats faster or flutters, and you may feel breathless. The fluttering could be more evident when you exercise, or consume certain foods or beverages. People who experience chronic anxiety or stress can have more PVCs, and some medications like amiodarone digoxin, and cocaine may increase the risk of developing them.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medications. If they're a frequent occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. You can also lessen your stress levels by having enough sleep and working out.

If you have many PVCs the doctor might suggest a medical treatment called radiofrequency catheter ablation, which destroys cells that cause PVCs. This is done by a specialist known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms but it doesn't stop them from recurring in the future. In some instances it can increase your risk of having atrial fibrillation (AFib), which can lead to stroke. It is not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, can make your heart appear to flutter or skip one beat. These heartbeats can be harmless, but it is important to talk to your doctor in case you experience frequent episodes or signs like dizziness or weakness.

Normally, electrical signals begin in the sinoatrial node which is in the top right side of the heart. These signals move down to the lower chambers (or ventricles) which pump blood. The ventricles then expand to push blood into your lungs, Window hinge Repair and then return to the heart to begin the next pumping cycle. But a PVC starts in a different place, from the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur, they make the heart beat faster or feel as if it skipped one beat. If you have just a few episodes but no other symptoms, your cardiologist probably won't treat you. If you've got a lot of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, also known as an ECG to determine the heart's rate over the course of 24 hours. The doctor may also suggest wearing a Holter monitor that will track the heart's rhythm over time to determine how many PVCs you have.

If you've had previously from a heart attack or cardiomyopathy - a condition which affects the heart's blood flow - must take their PVCs seriously and consult a cardiologist about lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat for example, a beta blocker.

Even if you don't experience any other signs, you should still get PVCs examined by an cardiologist if they occur often. These irregular heartbeats could signal a problem with the structure of your heart or Double Glazing Repair lungs and if they happen often enough, they can weaken your heart muscle. Most people with PVCs do not have any issues. They want to know if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs can feel like heartbeats that flutter, especially if they are frequent and intense. People who experience them often may feel weak. They can also happen with training, even though many athletes who get them do not have any issues in their heart or health. PVCs can show up on tests such as an electrocardiogram, or Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

Most of the time, a doctor will be able to determine if the patient has PVCs through a medical history and physical exam. But sometimes they might only notice them while examining the patient for other reasons, such as after a surgery or accident. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect cardiac disease when there is a reason to be concerned.

If your cardiologist concludes that your heart is structurally healthy, reassurance may be all you need. However, if your symptoms are causing discomfort or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may help. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medication that may be able to manage them.

Treatment

If PVCs aren't common or don't cause symptoms, they do not usually need treatment. If they occur frequently, your doctor might need to examine for heart issues or suggest lifestyle adjustments. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart, the electrical signal which creates your heartbeat is located different than the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or is beating faster. They're more common among people with heart problems however, it's not clear what causes them. PVCs can increase in frequency as you age, and may occur more frequently during exercises.

If a patient has frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. They will probably also do an exercise stress test to determine whether the additional beats are a result of physical activity. To find out if there are other causes for the increased beats the heart catheterization or Installing an MRI can be performed.

Most people who suffer from PVCs do not experience any complications and can lead a normal lifestyle. They could increase your risk for heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases, that means the heart muscle gets weaker and has trouble pumping blood through your body.

Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods that are high in fat and sodium and limit your consumption of tobacco and caffeine. It is also important to get enough rest and manage stress. Certain medications can increase your risk of getting PVCs. If you take any of these medicines it is essential to follow the advice of your doctor regarding healthy eating, exercising, and taking your medication.

In studies of patients with high PVC burdens (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This can lead to the need for a transplant in some individuals.
