How a VC Can Affect Your Heart

PVCs are common and can be experienced by a variety of people with no cause for concern. If they are frequent, PVCs may weaken your heart and increase your risk of heart failure.

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

Causes

PVCs are caused when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles and causes a mistimed heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart skipped a beating or feels fluttering. They can happen infrequently and cause no symptoms, or they may occur frequently enough to interfere with your daily life. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor may treat them with medication.

PVCs are generally harmless and do not increase your risk of developing heart disease. Frequent PVCs, however, can weaken the heart muscle over time. This is particularly the case if they are caused by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

PVCs can cause symptoms, such as a sensation of your heart racing an beat, or fluttering. It is also possible to feel exhausted. The fluttering may be more apparent when you exercise or consume certain drinks or foods. People with chronic anxiety or stress may have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the likelihood of developing them.

If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medications. If you have frequent PVCs, your double glazing doctor might recommend that you avoid certain foods and drinks, such as alcohol and caffeine. You can also take steps to reduce your stress, and get plenty of sleep and exercise.

If you have many PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells that cause PVCs. This is done by a specialist called an electrophysiologist. The treatment is generally successful in treating PVCs and reducing symptoms, but it does not stop them from becoming recurring in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib), a condition that can result in stroke. It's not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, can cause your heart seem to flutter or skip one beat. These extra heartbeats are usually harmless, but it is important to consult your physician when you experience frequent episodes or other symptoms such as dizziness or weakness.

The electrical signals normally begin in the sinoatrial, located in the upper right-hand corner of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles expand to push the blood into the lungs. They return to the center to begin the next cycle of pumping. But a Pvc Doctor begins in a different location that is separate from the bundle of fibers known as the Purkinje fibers, in the bottom left portion of the heart.

When PVCs happen, the heart may feel as if it's beating faster or slower. If you've experienced just a few episodes but no other symptoms, your doctor probably won't be able to treat you. However, if you have number of PVCs, the doctor may recommend an electrocardiogram, or ECG to determine the heart's rate over the course of 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 suffer from cardiomyopathy -which affects how the heart pumps blood -- should be aware of their PVCs and speak with a cardiologist about changes to their lifestyle. This includes abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, door and window doctor getting enough rest. A cardiologist may prescribe medications to slow the heartbeat like beta blockers.

If you have frequent PVCs even if you do not have other symptoms, you should consult a cardiologist. These extra heartbeats may signal a problem with the structure of your lungs or heart, and if they occur often enough, it could weaken your heart muscle. Most people who suffer from PVCs do not experience any problems. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, especially if they're intense or frequent. People who experience them often might feel faint. Exercise can trigger them, but many athletes who suffer from them do not have heart or health issues. PVCs can be detected in tests such as 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 study the heart and see how it's functioning.

A doctor is often able to tell the presence of PVCs by looking at them and taking a medical history. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason, such as after an accident or surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They can be used to identify cardiac problems in the event of any reason to be concerned.

If your cardiologist finds that your heart's structure is normal, reassurance is the only treatment needed. However, if your symptoms are causing discomfort or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can all aid in reducing the frequency of PVCs. If your symptoms persist or extreme, consult your doctor about medications that could be able to manage these symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually need treatment. If you are frequently affected or frequently, your doctor may wish to examine for any other heart problems and recommend lifestyle changes or medication. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs in your heart, the electrical signal which causes your heartbeat begins somewhere other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. It's not clear what causes these, but they're more common in people who have other heart issues. PVCs can increase in frequency as we age and can occur more often during exercising.

A physician should perform an ECG as well as an echocardiogram on a patient who suffers from frequent and painful PVCs to rule out structural heart diseases. The double glazing doctor will also likely perform an exercise stress test to determine if the additional heartbeats are due to physical exercise. To determine whether there are any other causes for the extra beatings an invasive heart catheterization or cardiac MRI can be performed.

Most people who suffer from PVCs do not experience any complications and can lead an ordinary life. But 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 regular, healthy diet and a lot of exercise can reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat and limit caffeine and tobacco. It is also important to sleep enough and manage stress. Certain medications can increase your risk of PVCs. If you are taking any of these medications it is essential to follow your doctor's advice regarding eating a healthy diet, exercising, and taking your medication.

In studies of patients suffering from PVC burdens that are high (more than 20% of heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This can result in a need for a heart transplant in a few patients.
