Pvc Doctor 101"The Ultimate Guide For Beginners
How a VC Can Affect Your Heart

Many people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

The rhythm of your heart is controlled by a bundle of nerve fibers situated in the upper right part of your heart. window doctor barnet Repair My Windows And Doors is known as the sinoatrial node or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.

Causes


PVCs are caused by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles and causes an irregular heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. They may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely and not cause any symptoms, but they may be frequent enough to impact your quality of living. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor might treat them with medication.

PVCs are generally safe and do not increase your risk of developing heart disease. A lot of PVCs, however, can weaken the heart muscle over time. This is especially the case if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

The symptoms of PVCs include feeling like your heart skips a beat or flutters, and you may feel exhausted. The fluttering may be more apparent when you exercise or consume certain drinks or foods. PVCs are more common in those suffering from chronic anxiety or stress. Certain medications, like digoxin, amiodarone, and cocaine, can increase their risk.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medication. If you experience frequent PVCs, your physician may suggest that you stay away from certain foods and drinks, like caffeine and alcohol. You can also take steps to reduce your stress and take advantage of plenty of rest and exercise.

If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which destroys the cells that cause them. The procedure is carried out by a specialist called an electrophysiologist. The treatment is usually successful in treating PVCs and reducing symptoms, but does not prevent them from recurring in the future. In some instances it can increase the risk of developing atrial fibrillation (AFib), which can result in stroke. This isn't common but it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to flutter or skip one beat. These extra heartbeats are usually harmless, but it is important to consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

Normally, electrical signals begin in the sinoatrial node, located in the upper right side of the heart. These signals move down to the lower chambers (or ventricles) that pump blood. The ventricles contract to push the blood into the lung. They return to the heart's center to begin the next cycle of pumping. But a PVC starts at a different spot and is located in the bundle of fibers known as the Purkinje fibers in the bottom left portion of the heart.

When PVCs happen they can make the heart appear to be racing or pounding. If you've experienced just a few episodes but no other symptoms, the doctor will probably not treat you. If you've got a lot of PVCs the doctor may recommend that you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. He or she may also suggest wearing a Holter monitor that records your heart rhythm over time, allowing you to see how many PVCs you have.

Anyone who has suffered a previous heart attack or cardiomyopathy - a condition which affects the heart's blood flow - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and ensuring adequate sleep. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you experience frequent PVCs, even if you do not have other symptoms, you should consult an expert in cardiology. These extra heartbeats may signal a problem with the structure of your lungs or heart, and if they occur often enough, can weaken the heart muscle. However, most people with PVCs don't have any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering especially if they are frequent and intense. Patients who have a lot of them might feel like they're going to faint. They can also happen with exercising, but most athletes who suffer from them don't have issues in their heart or health. PVCs may show up in tests like an electrocardiogram or Holter monitor. These are sticky patches that have sensors to record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.

A doctor may be able to identify if a person is suffering from PVCs from a history and physical exam. But sometimes they might only be able to detect them when they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias, and can be used when there is a concern of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance may be all you need. However, if your symptoms are causing discomfort or cause you to feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medications that could help control the symptoms.

Treatment

If PVCs aren't common or don't cause symptoms, they do not usually require treatment. If they happen frequently your doctor may want to check for heart conditions or recommend lifestyle modifications. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

When you have PVCs The electrical signal that triggers your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right corner of your heart. This could cause it to feel like your heart skips a beat or has a few extra beats. It's not clear what causes them, but they're more frequent in those with other heart problems. PVCs may increase in frequency as you age, and may occur more often during exercises.

If a patient experiences frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to rule out heart disease that is structural. They should also conduct an exercise stress test to see whether the extra beats are caused by physical activity. To determine whether there are other reasons for the extra beatings, a heart catheterization or a cardiac MRI could be conducted.

The majority of people with PVCs do not have any issues and can lead a normal life. However, they can increase your risk of having dangerous heart rhythm problems particularly if you have certain patterns of them. In some cases, that means the heart muscle gets weaker and is unable to pump blood through your body.

Regular exercise and a healthy diet can reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat, and limit your consumption of caffeine and tobacco. Sleep and stress are also crucial. Certain medications can increase your risk of PVCs. So if you take one of these medications it's crucial to follow your doctor's recommendations regarding eating healthy, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are high (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced myopathy in the heart was observed. This can result in a need for a heart transplant in a few patients.
