The Reasons Pvc Doctor Isn't As Easy As You Imagine
How a VC Can Affect Your Heart


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

A bundle of fibers located in the upper right part of your heart (the sinoatrial node, also known as SA) typically controls the heart's rhythm. Electrical signals travel from this node to the lower heart chambers, or ventricles.

Causes

PVCs are caused when the electrical impulse that usually initiates your heartbeat at a point known as the sinus node (also called the sinoatrial or SA node) isn't. Instead, the impulse starts in a different part of your heart--the ventricles--and causes an untimed beat. These extra beats, also called ventricular tachycardia or fibrillation, can feel like your heart skipped a beat or is like it is fluttering. They can occur infrequently and cause no symptoms, or they can occur frequently enough to affect your quality of life. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.

PVCs are generally harmless and don't increase the risk of heart disease. Regular PVCs, however, can weaken the heart muscle over time. This is particularly true if they are caused by a heart-related 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 beats faster or it flutters. You may feel breathless. The fluttering could be more noticeable when you exercise or consume certain foods or drinks. People who suffer from chronic anxiety or stress may have more PVCs and certain medications such as amiodarone, digoxin, and cocaine may increase the likelihood of developing them.

If you are experiencing occasional PVCs Your doctor might recommend lifestyle changes and medicines. If they're a frequent occurrence, you may need to avoid some foods and beverages, such as caffeine and alcohol. You can also take steps to lessen your stress levels, and get plenty of sleep and exercise.

If you've got a lot of PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. It destroys the cells that cause them. The procedure is carried out by a specialist, known as an electrophysiologist. The treatment is typically effective in treating PVCs, reducing symptoms but it does not stop them from recurring in the future. In some cases it can increase the risk of developing 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 to flutter. These extra heartbeats can be harmless, but you might want to consult your doctor when they occur frequently or if you notice symptoms like dizziness, or fatigue.

The normal electrical signals start in the sinoatrial, located in the upper right corner of the heart. They then move to the lower chambers, or ventricles, that pump blood. The ventricles expand to push the blood into the lungs. They return to the center to begin the next cycle of pumping. A PVC starts in a different location, the Purkinje fibers are located in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel like it is racing or pounding. If you've experienced just a few episodes but no other symptoms, your doctor will probably not treat you. If you've got a lot of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG, to measure your heart rate over the course of 24 hours. He or she might also recommend wearing a Holter monitor that will track your heart rhythm over time to see the number of PVCs you have.

Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -- a condition that affects how the heart pumps bloodand should take their PVCs seriously and speak with a cardiologist about lifestyle changes. These include abstaining from alcohol, caffeine and smoking, reducing anxiety and stress and getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you experience frequent PVCs even if you do not have any other symptoms, you should consult a cardiologist. These extra heartbeats can indicate problems with the structure of your heart or other health conditions and, over time when they are frequent enough, they may weaken the heart muscle. Most people who suffer from PVCs don't experience any problems. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs can feel like heartbeats that flutter, particularly if they're frequent and intense. People who experience them frequently might feel faint. Exercise can trigger them, but most athletes who experience them do not have heart or health issues. PVCs can show up in tests like an electrocardiogram or a Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.

A doctor can often tell the presence of PVCs by examining them and taking their medical history. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason such as following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They are able to identify cardiac problems if there is any concerns.

If your cardiologist finds that your heart is structurally normal, reassurance will be the only remedy required. However, if your symptoms are bothersome or cause you to feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. windows doctor and maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If the symptoms persist or are extreme, talk with your physician about possible medications that can control the symptoms.

Treatment

If PVCs do not cause any symptoms or happen rarely they aren't usually in need of treatment. If you have them often and frequently, your doctor might want to look for any other heart problems and suggest lifestyle changes or medication. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart, the electrical signal which causes your heartbeat begins somewhere different than the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. It can feel like your heart skips beats or has a few extra beats. They're more common among people suffering from heart disease however it's unclear the reason behind them. PVCs may increase in frequency as you age, and they might occur more frequently during exercising.

A doctor should conduct an ECG as well as an echocardiogram on a patient who suffers from frequent and painful PVCs to identify structural heart conditions. The doctor may also conduct an exercise stress test to determine if the additional heartbeats are caused by physical exercise. To find out whether there are any other causes for the extra beatings, a heart catheterization or a cardiac MRI could be conducted.

Most people with PVCs do not experience any complications and can lead a normal lifestyle. But they can increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In some instances, this means that your heart muscle gets weaker and is having difficulty pumping blood throughout your body.

A healthy and balanced diet and a lot of exercise can help reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium and limit your consumption of tobacco and caffeine. You should also try to get enough rest and reduce stress. Certain medicines can also increase the risk of developing PVCs. If you take any of these medicines it is crucial to follow the advice of your doctor about eating healthy exercising, as well as taking your medication.

Studies of patients who had a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. This could lead to the need for a heart transplant in some individuals.
