Learn The Pvc Doctor Tricks The Celebs Are Utilizing
How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase the chance of suffering from heart failure.

The heart's rhythm is controlled by a group of nerve fibers situated in the upper right-hand part of your heart. This is known as the sinoatrial node, or SA. Electrical signals are transmitted to the lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. Instead, the impulse starts in another area of your heart called the ventricles and triggers a wrongly timed beat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beating or feels like it is fluttering. They can occur infrequently and have no symptoms or they can happen often enough to affect your quality of life. Your doctor may prescribe medicine in the event that they are frequent or cause dizziness, weakness or fatigue.

For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Regular PVCs however, may weaken your heart muscle over time. This is particularly true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

The symptoms of PVCs include a feeling that your heart beats faster or flutters, and you may feel exhausted. The fluttering can be more apparent when you exercise or consume certain drinks or foods. PVCs are more prevalent in people with chronic anxiety or stress. Some drugs, like digoxin, amiodarone and cocaine, may increase the risk of developing PVCs.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medication. If they're a frequent occurrence, you may need to stay clear of certain drinks and foods, such as caffeine and alcohol. You can also take steps to lessen your stress and take advantage of plenty of rest and exercise.

If you're suffering from many PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. This destroys the cells that are responsible for PVCs. This is done by a specialist called an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases, it can increase your risk of atrial fibrillation (AFib) which can cause stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, may make your heart appear to skip or flutter one beat. These heartbeats that are not normal can be harmless, but you may want to consult your doctor if they are frequent or if you notice symptoms such as dizziness or fatigue.

Normally, electrical signals begin at the sinoatrial junction, located in the top right side of the heart, and move down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to propel blood into your lungs and return to the heart to start the next cycle of pumping. However, a PVC starts in a different location, from the bundle of fibers called the Purkinje fibers in the left-hand side of the heart.

When PVCs occur, they can make the heart beat faster or feel like it skipped the beat. If you experience only one or two episodes, and no other symptoms are present your cardiologist may not treat you. If you've got a lot of PVCs, the doctor may suggest an electrocardiogram, or ECG to gauge your heart rate over 24 hours. They may also recommend wearing a Holter monitor that will track the heart's rhythm over time, allowing you to see how many PVCs you have.

Anyone who has suffered an earlier heart attack or cardiomyopathy - an illness that affects the way the heart pumps blood - should take their PVCs very seriously and consult a cardiologist about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may also prescribe medication to slow the heartbeat like beta blockers.


If you are experiencing frequent PVCs even if you don't have any other symptoms, you should consult an expert in cardiology. These heartbeats that are irregular could signal a problem with the structure of your heart or lungs and if they happen often enough, they can weaken the heart muscle. But the majority of people with PVCs do not experience any issues. 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 particularly if they're frequent and intense. People who experience them frequently might feel faint. They can also happen with training, even though many athletes who experience them don't have any problems with their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses from your heart. windows doctor may also perform an echocardiogram, which uses ultrasound to examine the heart and observe how it's working.

A doctor is often able to tell if a patient has PVCs by examining them and taking their medical history. But sometimes they might only notice them while examining the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They are able to detect heart disease if there is any concerns.

If your cardiologist determines that your heart is structurally normal, reassurance will be the only remedy required. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms continue or are extreme, talk with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If you have them often or frequently, your doctor may wish to look for any other heart problems and recommend lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs, the electrical signal that triggers your heartbeat is generated from a place outside of the sinoatrial node (SA node) located in the upper right corner of your heart. It can feel like your heart skips a beat or is beating faster. It's not known what causes them, but they're more frequent in those with other heart conditions. PVCs may increase in frequency with age and might happen more often during exercises.

If a patient experiences frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to rule out structural heart disease. They will probably also do an exercise stress test to see if the extra beats are a result of physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be done to look for other causes for the additional beats.

Most people who suffer from PVCs do not suffer from any issues and can live an ordinary life. However, they can increase your risk of having dangerous heart rhythm issues, especially if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and has trouble pumping blood through your body.

A regular, healthy diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat and reduce your intake of caffeine and tobacco. Stress and sleep are also crucial. Certain medicines can also increase your risk of getting PVCs. If you take any of these medications it is essential to follow your doctor's advice regarding healthy eating and exercising as well as taking your medication.

Studies of patients suffering from a high amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can result in the need for a heart transplant in a few patients.
