Why Pvc Doctor Isn't As Easy As You Think
How a VC Can Affect Your Heart

Many people have occasional PVCs with no problems. If they occur often, PVCs may weaken your heart and increase your chance of suffering from heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial, or SA, node) usually controls your heart's rhythm. Electrical signals travel from there to the lower chambers of your heart, or ventricles.

Causes

PVCs happen when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. The impulse actually begins in the ventricles, causing an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They may happen rarely and not cause any symptoms, or they may occur frequently enough to interfere with your daily life. Your doctor may prescribe medication in the event that they are frequent or cause weakness, dizziness or fatigue.

For most 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 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 it flutters. You may feel exhausted. The fluttering may be more noticeable when you exercise or consume certain beverages or foods. People who experience chronic stress or anxiety can have more PVCs, and some drugs like amiodarone digoxin, and cocaine may increase the likelihood of developing them.

If you experience occasional PVCs Your doctor might recommend lifestyle changes and medicines. If you have frequent PVCs, your doctor may suggest that you stay away from certain drinks and foods, like caffeine and alcohol. You can also lower your stress by having enough sleep and exercising.

If you have lots of PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. The treatment is generally successful in treating PVCs which reduce symptoms, but does not prevent them from recurring in the future. In some cases it can increase your risk of having atrial fibrillation (AFib), which can cause a stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are harmless, however you might need to see your doctor if they are frequent or if you notice symptoms such as dizziness or fatigue.

Normaly, electrical signals begin in the sinoatrial region, which is in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles expand to push the blood into the lung. They return to the center to start the next cycle of pumping. A PVC begins in a different place in the Purkinje fibres bundle at the left-hand side of the heart.

When PVCs happen and the heart is affected, it may appear to be skipping a beat or pounding. If you experience only just a few episodes and there are no other symptoms the cardiologist will likely not treat you. If you've got a large number of PVCs the doctor may suggest an electrocardiogram, or ECG to gauge your heart rate over 24 hours. He or she might also suggest wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

Anyone who has had a prior heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood- should take their PVCs seriously and speak with a cardiologist about lifestyle changes. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't experience any other symptoms, you should still get PVCs examined by a cardiologist if they happen frequently. These heartbeats that are irregular could indicate a problem in the structure of your heart or lungs, and if they occur frequently enough, they can weaken your heart muscle. The majority of people with PVCs do not experience any issues. They simply want to be aware that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs can be akin to heartbeats that flutter, particularly if they're frequent and intense. Patients who have a lot of them may feel they're going to faint. Exercise can trigger them, but many athletes who suffer from them do not have heart or health issues. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to study the heart and determine how it's working.

A doctor may be able to tell whether the patient has PVCs through a medical history and physical exam. Sometimes, however, they may only notice PVCs when examining a patient for another reason such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They may be used to detect cardiac disease when there is a concern.


If your cardiologist determines your heart is structurally healthy, reassurance could be all you need. If your symptoms are troubling or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If windows doctor are experiencing symptoms that are persistent or extreme, consult your doctor about medication that may be able to manage these symptoms.

Treatment

If PVCs aren't causing symptoms or happen rarely generally, they don't require treatment. If they happen frequently, your doctor might be able to look for heart problems or suggest lifestyle adjustments. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) in the top right side of your heart. This can cause your heart to feel like it skips a beating or has additional beats. PVCs are more frequent among those with heart problems however it's unclear the reason behind them. PVCs can increase in frequency with age and might happen more frequently during exercises.

If a patient experiences frequent and painful PVCs doctors should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely perform an exercise stress test to determine if the extra heartbeats are related to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study can be performed to find other causes of the increased beats.

Most people who suffer from PVCs are not affected and live the normal life. They may increase the risk of developing heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. 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 you should also reduce your intake of caffeine and tobacco. Stress and sleep are also important. Some medicines can also increase the risk of developing PVCs. If you're taking one of these medications it is important to follow the doctor's advice about a healthy diet, exercise and taking your medication.

In studies of patients suffering from high PVC burdens (more than 20% of total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. Certain people may require a heart transplant.
