A Look At The Myths And Facts Behind Pvc Doctor
How a VC Can Affect Your Heart

Many people have occasional PVCs and have no issues. If they are frequent, PVCs may weaken your heart 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-hand corner of your heart. This is called the sinoatrial node, or SA. Electrical signals travel to the lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse which normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. Instead, the impulse starts in a different area of your heart, the ventricles, and causes an untimed beat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They may occur infrequently and not cause any symptoms, but they can occur frequently enough to affect your standard of life. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor could treat them with medication.

For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is particularly true if they are caused by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.

The symptoms of PVCs include feeling like your heart beats faster or flutters, and you may feel breathless. The fluttering can be more apparent when you exercise or consume certain beverages or foods. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Certain medications, such as digoxin, amiodarone and cocaine, can also increase the risk.

If you experience occasional PVCs your doctor might suggest lifestyle changes and medication. If they're a frequent occurrence, you may need to avoid some foods and beverages, such as alcohol and caffeine. You can also lower stress by having enough sleep and exercising.

If you have a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is generally effective in treating PVCs and reducing symptoms, but does not prevent them from returning in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib) which is a condition that can lead to stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats can be harmless, however you might need to see your doctor in the event of frequent heartbeats or if you are experiencing symptoms like dizziness, or fatigue.

The electrical signals normally begin in the sinoatrial area, which is located in the upper right-hand 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 lung. They then return to the center to start the next cycle of pumping. A PVC begins in a different location in the Purkinje fibres bundle in the left side of the heart.

When PVCs happen and the heart is affected, it may feel as if it's skipping a beat or pounding. If you only have a few episodes, and no other symptoms are present the cardiologist will likely not treat you. If you've got a large number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG to gauge the heart's rate over a 24-hour period. He or she may also suggest wearing a Holter monitor that records the heart's rhythm over time to see the number of PVCs you have.

Anyone who has suffered previously from a heart attack or cardiomyopathy - an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs even if you don't have any other signs, you should see an expert in cardiology. These irregular heartbeats could be a sign of a problem with the structure of your lungs or heart, and if they occur often enough, can weaken the heart muscle. The majority of people with PVCs do not experience any problems. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, particularly when they're frequent or intense. People who experience them regularly may feel faint. They can also occur with exercise, though many athletes who experience them do not have any issues in their heart or health. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to examine the heart and see how it's functioning.

A doctor can often tell whether a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes, however, door doctor wisbech may only notice PVCs when examining patients for a different reason, like following an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They are able to identify cardiac problems when there is a concern.

If your cardiologist has determined that 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 as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms persist or extreme, consult your physician about the medications that may be able to reduce them.

Treatment

If PVCs aren't causing symptoms or occur rarely, they usually don't need treatment. If they happen frequently your doctor may want to check for heart conditions or recommend lifestyle changes. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs, the electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) located in the upper right side of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. It's not clear what causes these symptoms, but they're common in people who have other heart issues. PVCs can become more frequent as you age, and they might occur more frequently during exercising.

If a patient experiences frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to see if the extra beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be conducted to determine other causes for the additional beats.

Most people with PVCs do not suffer from any complications and can lead an ordinary life. However, they may increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases, that means that the heart muscle becomes weaker and has trouble pumping blood throughout your body.

Regular exercise and a balanced diet will reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium as well as restrict your intake of tobacco and caffeine. Sleep and stress are also important. Some medicines may also increase your risk for PVCs. If you are taking one of these medicines it is important to follow your doctor's recommendations about eating well, exercising and taking your medication.


Studies of patients who had an excessive amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. This can result in the need for a transplant in a few people.
