An Guide To Pvc Doctor In 2023
How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by a wide range of people without causing any problems. If they occur often, PVCs may weaken your heart and increase the risk of heart failure.
A bundle of fibers in the upper right part of your heart (the sinoatrial node, also known as SA) typically controls the heart's rhythm. Electrical signals travel to the lower heart chambers or ventricles.
Causes
PVCs happen by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart beats faster or feels fluttering. They may occur infrequently, causing no symptoms, but they could also happen frequently enough to affect your quality of life. Your doctor may prescribe medication if they are frequent or cause dizziness, weakness or fatigue.
PVCs are generally harmless and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially true if they are caused by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.
The signs of PVCs include feeling like your heart skips a beat or flutters, and you may feel breathless. The fluttering can be more noticeable if you exercise, or consume certain foods or beverages. PVCs are more prevalent in people with chronic anxiety or stress. Some medications, such as digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs.
If you experience occasional PVCs your doctor might suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to avoid certain drinks and foods like alcohol and caffeine. You can also reduce your stress levels by taking enough rest and working out.
If you have a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. Electrophysiologists are the ones who execute this procedure. The treatment is usually successful in treating PVCs which reduce symptoms, but does not prevent them from returning in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib), an illness that can lead to stroke. It is not common, but it can be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, can make your heart seem to flutter or skip the beat. These extra heartbeats are harmless, but you may need to see your doctor when they occur frequently or if you notice symptoms like dizziness or fatigue.
Normally, electrical signals start in the sinoatrial node which is in the top right-hand side of the heart. They descend to the lower chambers (or ventricles) which pump blood. The ventricles expand to push blood into the lungs, and then return to your heart to begin the next cycle of pumping. However, a PVC starts at a different spot and is located in the bundle of fibers known as the Purkinje fibers, in the left-hand side of the heart.
When PVCs happen and the heart is affected, it may appear to be racing or pounding. If door and window doctor have only just a few episodes and no other symptoms are present your cardiologist may not prescribe treatment. However, if you have large number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG to determine the heart's rate over 24 hours. The doctor may also recommend wearing a Holter monitor that records your heart rhythm over time, allowing you to see how many PVCs you have.
People who have had a prior heart attack or have cardiomyopathy -- a condition that affects how the heart pumps blood -- should be aware of their PVCs and speak with an expert in cardiology about lifestyle changes. These include the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough sleep. A cardiologist may prescribe beta blockers to slow down the heartbeat.
If you have frequent PVCs even if do not have any other signs, you should see a cardiologist. These extra heartbeats may signal a problem with the structure of your heart or lungs and if they happen often enough, can weaken your heart muscle. Most people with PVCs do not have any issues. They just want to be aware that the fluttering and racing heartbeats aren't normal.
Diagnosis
PVCs might appear to be fluttering or skip heartbeats, particularly when they are frequent or intense. People who get lots of them may feel they're going to faint. Exercise can cause them, but many athletes who experience these symptoms do not have heart or health issues. PVCs can show up in tests like an electrocardiogram, or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to examine the heart and determine how it's functioning.
A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason, like following an accident or a surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and they might be used if there's any concern of heart disease.
If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. However, if your symptoms are causing discomfort or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise, maintaining a healthy weight and drinking enough fluids can aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your physician about the medications that may be able to reduce them.
Treatment
If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If you experience them frequently and frequently, your doctor might want to check for other heart conditions and suggest lifestyle changes or medications. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate them.
If you have PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips a beat or is beating faster. It's not known what causes these, but they're more common in people with other heart problems. PVCs may increase in frequency as you age, and may occur more frequently during exercises.
If a patient experiences frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to see whether the extra beats are caused by physical exercise. To find out whether there are other reasons for the extra beatings an invasive heart catheterization or a cardiac MRI could be conducted.
The majority of people with PVCs have no complications and live an ordinary life. They may increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some instances, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout the body.
Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Some medicines may also increase your risk for PVCs. If you take any of these medications it is essential to follow your doctor's advice about eating healthy exercising, as well as taking your medication.
In studies of patients with PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Some patients may require a heart transplant.
