A Reference To Pvc Doctor From Start To Finish
How a VC Can Affect Your Heart

A lot of people experience occasional PVCs without any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial or SA node) typically controls the heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers, or ventricles.

Causes

PVCs happen by the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) is not initiated. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat or is like it's fluttering. They may occur infrequently, causing no symptoms, but they may also happen frequently enough to affect your standard of life. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.


For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. Frequent PVCs however, may weaken your heart muscle over time. This is particularly the case if they are caused by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.

The symptoms of PVCs include feeling like your heart skips a beat or it flutters. You may feel exhausted. The fluttering can be more apparent when you exercise, or consume certain foods or beverages. People who suffer from chronic stress or anxiety can have more PVCs, and some drugs like amiodarone digoxin, and cocaine may increase the risk of developing them.

If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication. If you have frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as caffeine and alcohol. You can also take steps to reduce your stress, and take advantage of plenty of rest and exercise.

If you're experiencing many PVCs the doctor might suggest a medical treatment called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. Electrophysiologists are the ones who carry out this procedure. It is usually successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from recurring in the future. In some instances it may increase your risk of atrial fibrillation (AFib) which could cause stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, can cause your heart seem to skip or flutter the beat. These heartbeats can be harmless, however, you should consult your physician if you have frequent episodes or other symptoms such as dizziness or weakness.

The electrical signals typically begin at the sinoatrial junction, located in the upper right side of the heart. They descend to the lower chambers (or ventricles) which pump blood. The ventricles expand to pump blood into the lung. They return to the center to start the next cycle of pumping. However, a PVC begins at a different spot and is located in the bundle of fibers called the Purkinje fibers in the left-hand side of the heart.

When PVCs occur, they cause the heart beat or feel like it skipped the beat. If repairmywindowsanddoors experience only a few episodes, and no other symptoms are present, your cardiologist will probably not prescribe treatment. However, if you have number of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG to determine your heartbeat over a 24-hour period. He or she might also recommend wearing a Holter monitor that will track your heartbeat over time to determine how many PVCs you have.

If you've had an earlier heart attack or cardiomyopathy, an illness that affects way the heart pumps blood - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. This includes avoiding alcohol, caffeine and smoking, managing anxiety and stress, and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

Even if there aren't any other symptoms, you should still get PVCs checked by an cardiologist if they occur often. These irregular heartbeats could be a sign of an issue with the structure of your heart or other health conditions and, over time if they occur often enough, they can weaken the heart muscle. But most people with PVCs don't experience any problems. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, especially when they are frequent or intense. People who get lots of them might feel like they're going to faint. Exercise can cause them, but most athletes who experience these symptoms do not have heart or health problems. PVCs may show up in tests like an electrocardiogram or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to study the heart and observe how it's working.

Often, a doctor will be able to determine if a person has PVCs from a patient's history and physical examination. Sometimes, however, they may only notice PVCs when examining patients for a different reason, such as after an accident or surgical procedure. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias, and they might be used if there's any concern of cardiac disease.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. If your symptoms are causing discomfort or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medication that could help manage these symptoms.

Treatment

If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If you experience them frequently and frequently, your doctor might want to examine for other heart issues and suggest lifestyle changes or medications. You could also have a procedure (called radiofrequency cathode ablation) to get rid them.

If you have PVCs in your heart the electrical signal that creates your heartbeat is located different than the sinoatrial (SA) node, which is located in the upper right corner of your heart. This could cause your heart to feel as if it skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease however it's unclear the reason behind them. PVCs can increase in frequency as you age, and may occur more often during exercising.

A doctor should perform an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to see whether the extra beats are a result of physical exercise. To determine whether there are other reasons for the extra beatings an invasive heart catheterization or a cardiac MRI could be conducted.

Most people who suffer from PVCs do not have any issues and live an ordinary life. However, they can increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.

A healthy, regular diet and a lot of exercise can reduce the risk of developing PVCs. Avoid foods that are high in sodium and fat, and limit your consumption of tobacco and caffeine. Sleep and stress are also important. Certain medicines can also increase your risk for PVCs. If you are taking any of these medications it is crucial that you follow your doctor's recommendations about eating healthy, exercising, and taking your medication.

Studies of patients with a high burden 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 a heart transplant.
