How a VC Can Affect Your Heart
PVCs are common and can be experienced by a variety of people without causing any issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The rhythm of your heart is controlled by a bundle of nerve fibers situated in the upper right-hand corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel to ventricles or lower chambers of your heart.
Causes
PVCs occur 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 begins in the ventricles and causes a mistimed heartbeat. double glazing doctor are called ventricular tachycardia or ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They can happen infrequently and not cause any symptoms, but they may be frequent enough to impact your quality of living. Your doctor may prescribe medicine in the event that they are frequent or cause dizziness, weakness or fatigue.
For the majority of people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is particularly relevant if they are triggered by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.
The signs of PVCs include a feeling that your heart beats faster or flutters, and you may feel breathless. The fluttering may be more evident if you exercise, or eat or drink certain foods or beverages. People who suffer from chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the chance of developing them.
If you experience occasional PVCs, your doctor may recommend lifestyle changes and medicines. If they're a frequent occurrence, you may have to avoid certain foods and beverages, such as caffeine and alcohol. You can also lessen your stress levels by taking enough rest and working out.
If you have a lot of PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. It destroys cells that cause PVCs. The procedure is carried out by a specialist known as an electrophysiologist. The treatment is usually successful in treating PVCs which reduce symptoms, but does not prevent them from becoming recurring in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib), a condition that can cause stroke. It's not common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs may cause your heart to skip or flutter. These extra heartbeats are harmless, but you may need to see your doctor when they occur frequently or if you are experiencing symptoms like dizziness, or fatigue.
The electrical signals normally begin in the sinoatrial, located in the upper right-hand corner of the heart. They then travel to the lower chambers, or ventricles, that pump blood. The ventricles expand to push blood into your lungs and return to the heart to start the next pumping cycle. However, a PVC begins in a different location, from the bundle of fibers known as the Purkinje fibers in the lower left part of the heart.
When PVCs occur they can make the heart appear to be skipping a beat or pounding. If you've experienced a few episodes and no other symptoms, your cardiologist probably won't treat you. If you've got a lot of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG to gauge your heartbeat over 24 hours. He or she may also recommend wearing a Holter monitor that will track your heart rhythm over time to see the number of PVCs you have.
Anyone who has had a previous heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood -- should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may also prescribe medication to slow heartbeat, like beta blockers.
Even if there aren't any other symptoms, you should still get PVCs examined by an cardiologist if they occur often. These heartbeats that are irregular could be a sign of a problem with the structure of your heart or lungs and if they happen often enough, can weaken your heart muscle. 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 felt as fluttering or skipped heartbeats, especially if they are frequent or intense. People who experience them regularly may feel weak. Exercise can cause them, but most athletes who experience these symptoms do not have heart or health issues. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to study the heart.
A doctor can often tell whether a patient has PVCs by looking at them and taking a medical history. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason, such as after an accident or surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They can be used to detect cardiac disease when there is a reason to be concerned.
If your cardiologist concludes that your heart's structure is normal, reassurance will be the only treatment required. However, if your symptoms are troubling or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough fluids can decrease the likelihood of PVCs. If your symptoms persist or severe, talk to your physician about the medications that could be able to control these symptoms.
Treatment
If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If you have them often or frequently, your doctor may wish to look for other heart conditions and recommend lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to get rid of them.
If you suffer from PVCs the electrical signal that triggers your heartbeat is generated from a place different than the sinoatrial nerve (SA node) located in the upper right part of your heart. It can feel like your heart skips a beat or has extra beats. PVCs are more prevalent 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 may be more frequent during exercise.
A physician should perform an ECG as well as an echocardiogram on a patient that suffers from frequent and painful PVCs to identify structural heart conditions. The doctor will also likely perform an exercise stress test to determine if the additional heartbeats are caused by 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 do not have any issues and can live the normal life. But they can increase your risk of having dangerous heart rhythm issues, especially if you have certain patterns of them. In some instances, this means the heart muscle gets weaker and has trouble pumping blood through your body.
Regular exercise and a balanced diet will lower your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of caffeine and tobacco. You should also try to get enough rest and reduce stress. Some medicines can also increase your risk of PVCs. If you are taking any of these medicines, it is important to follow your doctor's recommendations about eating healthy and exercising as well as taking your medication.
Studies of patients suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in certain people.
