5 Pvc Doctor Lessons From The Pros
How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by many people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

A bundle of fibers in the top right portion of your heart (the sinoatrial or SA node) typically regulates your heart rhythm. Electrical signals travel from this node to the lower heart chambers, or ventricles.

Causes

PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. Instead, the impulse is generated in a different part of your heart called the ventricles and triggers a mistimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beat or feels fluttering. They can occur infrequently and not cause any symptoms, or they can happen often enough to interfere with your quality of life. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.

PVCs are generally harmless and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

PVCs can cause symptoms like a feeling of your heart racing a beat, or the feeling of your heart fluttering. You may also feel exhausted. The fluttering may be more noticeable when you exercise or consume certain foods or drinks. PVCs are more common for those who suffer from chronic anxiety or stress. Certain medications, such as digoxin, amiodarone or cocaine, can increase the risk of developing PVCs.

If you have occasional PVCs, your doctor may recommend lifestyle changes and medicines. If they're a frequent occurrence, you may have to stay clear of certain drinks and foods, such as caffeine and alcohol. You can also take steps to reduce your stress, and get plenty of sleep and exercise.

If you're suffering from a lot of PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. Electrophysiologists are the ones who execute this procedure. The treatment is typically effective in treating PVCs which reduce symptoms, but it does not stop them from recurring in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib), which can lead to stroke. It's not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, may make your heart appear to flutter or skip a beat. These extra heartbeats are harmless, however you might want to consult your doctor when they occur frequently or if you experience symptoms such as dizziness or fatigue.

Normally, electrical signals start at the sinoatrial junction, which is in the top right side of the heart, and descend to the lower chambers (or ventricles) which pump blood. The ventricles then contract to pump blood into the lungs. They return to the center to begin the next cycle of pumping. A PVC starts in a different place that is the Purkinje fibres bundle at the left side of the heart.

When PVCs happen they can make the heart feel like it is skipping a beat or pounding. If you only have just a few episodes and no other symptoms are present your cardiologist may not be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. They may also recommend wearing a Holter Monitor which tracks your heartbeat and tracks the number of PVCs.

Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood - must be aware of their PVCs and talk to a cardiologist about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, reducing anxiety and stress and ensuring adequate sleep. A cardiologist may prescribe medications to slow the heartbeat, such as beta blockers.

If you experience frequent PVCs even if do not have any other signs, you should see a cardiologist. These extra heartbeats may signal a problem with the structure of your lungs or heart, and if they occur frequently enough, it could weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them frequently may feel weak. They can also happen with training, even though many athletes who get them don't have issues in their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to look at the heart and see how it's functioning.

Most of the time, a doctor will be able to identify if a person is suffering from PVCs from a history and physical exam. But sometimes they might not be aware of them until they examine the patient for other reasons, such as following an accident or surgery. the glass doctor monitoring systems can also help detect PVCs and other arrhythmias, and could be utilized if there's any concern of cardiac disease.

If your cardiologist has determined that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress can aid. Getting regular exercise, staying at a healthy weight and drinking enough water can reduce your episodes of PVCs. If your symptoms are persistent or severe, talk to your doctor about medications that may be able to control the symptoms.

Treatment


If PVCs aren't causing symptoms or happen rarely, they usually don't need treatment. If they occur frequently your doctor may be able to look for heart problems or suggest lifestyle changes. You could also have an operation to rid yourself of them (called radiofrequency catheter ablation).

When you have PVCs The electrical signal that triggers your heartbeat begins somewhere different than the sinoatrial nerve (SA node) located in the upper right corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. It's not known what causes these, but they're more common in people with other heart conditions. PVCs may increase in frequency as we age and can occur more often during exercises.

If a patient is experiencing frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They will probably also do an exercise stress test to determine whether the additional beats are a result of physical exercise. To determine whether there are other reasons for the increased beats the heart catheterization or cardiac MRI could be conducted.

The majority of people with PVCs do not suffer from any problems and can enjoy a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and has trouble pumping blood through your body.

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

Studies of patients with a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. This can result in the need for a heart transplant in some people.
