The Best Pvc Doctor Gurus Are Doing Three Things
How a VC Can Affect Your Heart


Many people experience occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is controlled by a group of nerve fibers situated in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that typically initiates your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA Node) isn't. The impulse actually starts in the ventricles, which causes an irregular heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It may feel like the heart beats faster or feels like it is fluttering. They may happen rarely and have no symptoms or they can happen often enough to interfere with your daily life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor might treat them with medication.

PVCs are generally safe and do not increase the risk of heart disease. Regular PVCs however, may weaken the heart muscle over time. This is particularly relevant if they are triggered by a heart-related condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.

PVCs can trigger symptoms, such as a sensation of your heart racing an beat, or fluttering. You might also feel breathless. The fluttering may be more apparent if you exercise, or consume certain beverages or foods. PVCs are more prevalent in people with chronic stress or anxiety. Certain 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 medications. If they are a frequent occurrence, you may have to stay clear of certain foods and beverages, such as alcohol and caffeine. You can also take steps to lessen your stress levels, and get plenty of sleep and exercise.

If you're experiencing many PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation. This eliminates the cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. It is typically effective in treating PVCs and reducing symptoms, but it doesn't stop them from recurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib) which is which can cause stroke. This is rare but can be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, can make your heart appear to flutter or skip one beat. These extra heartbeats are harmless, but you might be advised to consult your physician in the event of frequent heartbeats or if you experience symptoms such as dizziness or fatigue.

Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right part of the heart. They then move to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles then contract to pump blood into the lungs. They return to the center to begin the next cycle of pumping. But a PVC begins at a different spot that is separate from the bundle of fibers known as the Purkinje fibers, located in the bottom left portion of the heart.

When PVCs occur they can make the heart feel as if it's racing or pounding. If you have only a few episodes, but no other symptoms, the cardiologist probably won't treat you. If you have a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. The doctor may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has suffered an earlier heart attack or cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs very seriously and consult a cardiologist about lifestyle modifications. These include abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, and getting enough rest. A cardiologist might prescribe medications to slow heartbeat, such as beta blockers.

If you experience frequent PVCs even if don't have any other symptoms, you should consult a cardiologist. These heartbeats that are irregular could be a sign of a problem with the structure of your lungs or heart, and if they occur often enough, they can weaken the heart muscle. But the majority of people suffering from PVCs don't experience any problems. They simply want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis

PVCs might appear to be fluttering or skip heartbeats, especially when they are frequent or intense. Patients who have a lot of them may feel they're going to faint. They can also occur during training, even though many athletes who suffer from them don't have any problems with their heart or health. PVCs could show up in tests such as 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 may be able to determine if the patient is suffering from PVCs through a medical history and physical examination. But sometimes they might only notice them while examining the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition.

If your cardiologist concludes that your heart is structurally normal, reassurance will be the only treatment required. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress may aid. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms are persistent or severe, speak to your physician about the medications that could be able to manage them.

Treatment

If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If they occur frequently, your doctor might want to check for heart issues or suggest lifestyle changes. You could also undergo an operation (called radiofrequency cathode ablation) to get rid of them.

If you have PVCs in your heart the electrical signal that creates your heartbeat is located other than at the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. It can feel like your heart skips a beat or is beating faster. It's unclear what causes these, but they're more common in people who have other heart conditions. PVCs are more likely to occur as you age, and may be more frequent during exercises.

If a patient experiences frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to rule out structural heart disease. They may also perform an exercise stress test to determine whether the extra beats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other reasons for the increased beats.

Most people with PVCs have no complications and can lead the normal life. They could increase your risk for heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In the window doctors , this means the heart muscle gets weaker and has trouble pumping blood through your body.

A healthy and balanced diet and plenty of exercise can reduce the risk of developing PVCs. You should avoid foods that are high in fat and sodium, and you should also restrict your intake of tobacco and caffeine. Stress and sleep are also important. Certain medications can increase your risk for PVCs. If you are taking one of these drugs it is important to follow the doctor's advice about eating well, exercising and taking your medication.

Studies of patients with an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can result in a need for a heart transplant in certain patients.
