How a VC Can Affect Your Heart

Many people experience occasional PVCs and have no issues. If they are frequent, PVCs may weaken your heart and increase your risk of heart failure.

The rhythm of your heart is usually controlled by a group of fibers located in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower heart chambers or ventricles.

Causes

PVCs are caused when the electrical impulse that usually initiates your heartbeat in a region called the sinus node (also known as the sinoatrial or SA node) isn't. The impulse actually begins in the ventricles, causing an untimed heartbeat. window doctors , also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can occur infrequently and cause no symptoms, or they can happen often enough to interfere with your quality of life. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor might treat them with medicine.

PVCs are generally harmless and do not increase the risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

PVCs can cause symptoms like a feeling of your heart skipping one beat, or even the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering may be more evident when you exercise or have certain drinks or foods. PVCs are more common in people with chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, may increase the risk of developing PVCs.

If you experience occasional PVCs Your doctor might suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor may recommend avoiding certain foods and drinks like caffeine and alcohol. You can also take steps to lessen your stress, and make sure you get enough sleep and exercise.

If you're suffering from a lot of PVCs The doctor may recommend a medical treatment known as radiofrequency catheter ablation. This destroys cells that cause PVCs. Electrophysiologists are the ones who execute this procedure. The treatment is typically successful in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib), a condition that can result in stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, can cause your heart appear to skip or flutter one beat. These extra heartbeats are usually harmless, however, you should talk to your doctor if you have frequent episodes or other symptoms such as dizziness or weakness.

The electrical signals normally begin in the sinoatrial area, which is located in the upper right-hand corner of the heart. They then move to the lower chambers, or ventricles, that pump blood. The ventricles contract to force blood into the lungs. They then return to the center to begin the next cycle of pumping. However, a PVC starts in a different place and is located in the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart.

When PVCs happen and the heart is affected, it may feel like it is racing or pounding. If you experience only a few episodes, and there are no other symptoms the cardiologist will likely not be able to treat you. If you've got a lot of PVCs the doctor may suggest an electrocardiogram, or ECG to gauge the heart's rate over 24 hours. He or she might also suggest wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

If you've had previously from a heart attack or cardiomyopathy, an illness that affects method by which the heart pumps blood - should take their PVCs very seriously and speak to a cardiologist about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist can prescribe medications to slow the heartbeat, like a beta blocker.

Even if you don't have any other indications it is still recommended to have PVCs examined by an expert in cardiology if they occur frequently. These irregular heartbeats could be a sign of an issue with the structure of your heart or to other health conditions and, over time, when they happen frequently enough, they could weaken the heart muscle. Most people with PVCs do not experience any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them often may feel weak. Exercise can cause PVCs, but a lot of athletes who suffer from them have no heart or health problems. PVCs may show up in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to study the heart and determine how it's working.

A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history. Sometimes however, they might only be able to detect PVCs when they examine patients for a different reason, such as after an accident or surgical procedure. Ambulatory ECG monitoring systems also help detect PVCs and other arrhythmias, and they might be used in the event of any suspicion of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance may be all that's needed. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as reducing stress may aid. Regular exercise, being at a healthy weight and drinking enough water can decrease the likelihood of PVCs. If your symptoms continue or are severe, talk with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually require treatment. If you have them often, your doctor may want to look for other heart conditions and suggest lifestyle changes or medication. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid them.

If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node located in the upper right-hand corner of your heart. This can cause your heart to feel as if it skips beats or has extra beats. It's unclear what causes these symptoms, but they're frequent in those with other heart problems. PVCs can increase in frequency with age and might happen more often during exercising.

A doctor should conduct an ECG and an echocardiogram for a patient who suffers from frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to see if the extra beats are a result of physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other causes of the increased beats.

The majority of people with PVCs are not affected and can lead an ordinary life. But they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some instances, this means that your heart muscle gets weaker and has trouble pumping blood throughout your body.

A regular, healthy diet and a lot of exercise can reduce the chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of caffeine and tobacco. Also, you should try 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 essential that you follow your doctor's recommendations regarding eating a healthy diet, exercising, and taking your medication.

In studies of patients with high PVC burdens (more than 20% of heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. Some patients may require an organ transplant.
