How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by many people with no cause for concern. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is usually controlled by a bundle of nerve fibers situated in the upper right corner of your heart. This is called the sinoatrial node or SA. Electrical signals travel to the ventricles, or lower chambers of the heart.

Causes

PVCs happen by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, which causes a mistimed heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beating or feels fluttering. They may happen rarely and cause no symptoms, or they may occur frequently enough to affect your daily life. If they occur frequently or cause dizziness, weakness or fatigue, your doctor might treat them with medicine.

double glazing doctor are generally harmless and don't increase your risk of developing heart disease. Over time, frequent PVCs can weaken the heart muscle. This is particularly true if they are caused by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

The symptoms of PVCs include feeling like your heart beats faster or it flutters. You may feel exhausted. The fluttering can be more noticeable if you exercise, or consume certain foods or beverages. People with chronic stress or anxiety can have more PVCs and certain medications such as amiodarone, digoxin, and cocaine may increase the chance of developing them.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medication. If they are a frequent occurrence, you may need to avoid certain drinks and foods, such as alcohol and caffeine. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise.

If you have a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells that are responsible for them. Electrophysiologists are the ones who carry out this procedure. The treatment is usually effective in treating PVCs and reducing symptoms, but does not prevent them from returning in the future. In some cases it can increase the risk of having atrial fibrillation (AFib) which is which can lead to stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, may make your heart appear to skip or flutter one beat. These heartbeats that are not normal can be harmless, however you might be advised to consult your physician if they are frequent or if you are experiencing symptoms like dizziness or fatigue.

Normally, electrical signals start in the sinoatrial node, located in the top right-hand side of the heart. These signals descend 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 in a different location, the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped one beat. If you experience just a few episodes but no other symptoms, the cardiologist probably won't treat you. If you have many PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. He or she might also recommend wearing a Holter monitor, which will record your heart rhythm over time to determine how many PVCs you have.

If you've had a previous heart attack or have suffered from cardiomyopathy - an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and speak to an expert in cardiology about lifestyle modifications. These include avoiding caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist can prescribe medication to slow the heartbeat for example, beta blockers.

If you experience frequent PVCs even if you do not have any other signs, you should see a cardiologist. These irregular heartbeats could be a sign of a problem with the structure of your heart or to other health conditions, and over time, when they are frequent enough, they could weaken the heart muscle. But most people suffering from PVCs don't have any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal.





Diagnosis

PVCs can be akin to heartbeats that flutter, especially if they are frequent and intense. People who experience them regularly might feel faint. Exercise can cause PVCs, but a lot of athletes who suffer from them have no heart or health issues. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. They use sticky patches with sensors to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to look at the heart and determine how it's functioning.

Often, a doctor will be able to identify if the patient has PVCs through a medical history and physical examination. Sometimes, they may not be aware of them until they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They are able to detect cardiac disease if there is any reason to be concerned.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are causing discomfort or cause you to feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Getting regular exercise, staying at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms are persistent or extreme, consult your physician about the medications that could help reduce them.

Treatment

If PVCs don't cause symptoms or are not frequent generally, they don't require treatment. If they happen frequently your doctor may need to examine for heart conditions or recommend lifestyle changes. You could also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located different than the sinoatrial (SA) node located in the upper right corner of your heart. It can feel like your heart skips a beat or is beating faster. They're more common among people who suffer from heart issues, but it's not known what causes them. PVCs can become more frequent as you age, and they could be more frequent during exercising.

If a patient is experiencing frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also perform an exercise stress test in order to determine if the extra heartbeats are related to physical exercise. To find out whether there are other reasons for the extra beatings, a heart catheterization or cardiac MRI could be conducted.

Most people with PVCs do not have any issues and live an ordinary life. They may increase your risk for dangerous heart rhythm disorders, especially if they occur in certain patterns. In some instances, this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

Regular exercise and a balanced diet will lower your risk of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. It is also important to get enough sleep and reduce stress. Certain medicines can also increase the risk of developing PVCs. If you are taking any of these medicines, it is important that you follow the advice of your doctor about eating healthy exercising, as well as taking your medication.

Studies of patients who had a high amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. Some patients may require an organ transplant.
