What Experts Say You Should Be Able To
How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

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

Causes

PVCs occur when the electrical impulse that normally starts your heartbeat in a part known as the sinus node (also called the sinoatrial or SA Node) doesn't. Instead, the impulse is generated in another area of your heart, the ventricles, and causes 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 fluttering. They may occur infrequently, causing no symptoms, but they can also happen frequently enough to affect your quality of living. Your doctor may prescribe medicine if they are frequent or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is especially relevant if the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.

PVCs can cause symptoms such as a feeling of your heart racing a beat, or the feeling of your heart fluttering. You may also feel breathless. The fluttering could be more evident when you exercise or consume certain drinks or foods. People with chronic stress or anxiety can have more PVCs, and some drugs like amiodarone digoxin, and cocaine can increase the likelihood of developing them.

If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication. If they're a frequent occurrence, you may have to stay clear of certain drinks and foods, such as alcohol and caffeine. You can also lessen stress by getting enough sleep and exercising.

If you have many PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. The procedure is carried out by a specialist known as an electrophysiologist. It is typically successful in treating the PVCs and reducing symptoms however it does not stop them from occurring in the future. In some cases it can increase the risk of atrial fibrillation (AFib), an illness that can result in stroke. It is not common, but it can be life-threatening.


Symptoms

Premature ventricular contractions, or PVCs, can make your heart appear to skip or flutter the beat. These heartbeats that are not normal can be harmless, but you might need to see your doctor if they are frequent or if you are experiencing symptoms such as dizziness or fatigue.

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 contract to force blood into the lung. They return to the center to begin the next cycle of pumping. A PVC begins at a different spot that is the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs occur, they make the heart beat faster or feel as if it skipped the beat. If you have only a few episodes, but no other symptoms, your doctor probably won't be able to treat you. If you've got a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG, to measure your heart rate over a 24-hour period. The doctor may also suggest wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

People who have suffered a heart attack in the past or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood - should take their PVCs seriously and speak with a cardiologist about changes to their lifestyle. Those include avoiding caffeine, alcohol and smoking, managing stress and anxiety and ensuring adequate sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other signs, you should still get PVCs checked by an expert in cardiology if they occur frequently. These extra heartbeats may signal a problem with the structure of your heart or lungs, and if they occur often enough, can weaken your heart muscle. Most people with PVCs don't experience any problems. They just want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, particularly when they're intense or frequent. People who get lots of them might feel like they're going to faint. Exercise can cause PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. door doctor may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to study the heart and determine how it's working.

A doctor will usually be able to determine whether a patient has PVCs by conducting a thorough examination and taking a medical history. However, sometimes they will only notice them while examining the patient for different reasons, like after an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to identify cardiac problems in the event of any concern.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. If your symptoms are causing you discomfort, or cause you to feel anxious, avoiding alcohol, caffeine and over-the counter decongestants, and the reduction of stress could help. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can reduce your episodes of PVCs. If the symptoms persist or are severe, speak with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs don't cause symptoms or occur rarely they aren't usually in need of treatment. If they are frequent, your doctor might want to check for heart problems or suggest lifestyle modifications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs The electrical signal that causes your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right corner of your heart. It can feel like your heart skips a beat or has extra beats. It's not clear what causes these symptoms, but they're common in people with other heart issues. PVCs can become more frequent as you age, and they could be more frequent during exercising.

A physician should perform an ECG and an echocardiogram on a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to determine whether the additional beats are due to physical exercise. To determine if there are other causes for the increased beats an invasive heart catheterization or cardiac MRI could be conducted.

Most people with PVCs don't experience any issues and can live a normal lifestyle. They can increase the risk of heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some instances, this means the heart muscle gets weaker and has trouble pumping blood through your body.

A healthy, regular diet and plenty of exercise can reduce the chances of developing PVCs. Avoid foods that are high in sodium and fat and reduce your intake of caffeine and tobacco. You should also try to get enough rest and reduce stress. Certain medicines can also increase the risk of developing PVCs. If you are taking any of these medicines it is crucial to follow your doctor's advice about eating healthy, exercising, and taking your medication.

In studies of patients with high PVC burdens (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. Certain people may require a heart transplant.
