Pvc Doctor Strategies From The Top In The Industry
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 the risk for heart failure.

The rhythm of your heart is controlled by a group of fibers located in the upper right-hand corner of your heart. This is called the sinoatrial node, or SA. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs occur when the electrical impulse that usually begins your heartbeat at a point called the sinus node (also called the sinoatrial node or SA node) doesn't. Instead, the impulse starts in a different area of your heart--the ventricles--and causes a wrongly timed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat or is fluttering. They can happen infrequently and have no symptoms or they can happen often enough to interfere with your daily life. Your doctor may prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.

For the majority of people, PVCs are harmless and do not increase the risk of developing heart disease or other health problems. Frequent PVCs, however, can weaken the heart muscle over time. This is particularly when the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure.

PVCs can trigger symptoms like a feeling of your heart beating one beat, or even the feeling of your heart fluttering. It is also possible to feel breathless. The fluttering may be more evident when you exercise, or eat or drink certain beverages or foods. People who suffer from chronic stress or anxiety can have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the chance of developing them.

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

If you have a lot of PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. The procedure is carried out by a specialist known as an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib), an illness that can cause stroke. It is not common however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or flutter. These extra heartbeats are usually harmless, but it is important to consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node, located in the top right portion of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to propel blood into the lungs, and then return to the heart to start the next cycle of pumping. A PVC begins in a different location that is the Purkinje fibres bundle in the bottom left of the heart.

When window doctor occur, they make the heart pound or feel as if it skipped a beat. If you have only a few episodes, but no other symptoms, the cardiologist probably won't treat you. If you've got 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 heartbeat and tracks the number of PVCs.

People who have had a previous heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps blood - should take their PVCs seriously and talk to a cardiologist about changes to their lifestyle. This includes the avoidance of alcohol, caffeine, and smoking, reducing anxiety and stress and ensuring adequate sleep. A cardiologist can also prescribe medication to slow heartbeat, like a beta blocker.

Even if there aren't any other signs, you should still get PVCs examined by an expert in cardiology if they occur often. 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 the heart muscle. However, most people suffering from PVCs don't have any issues. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them frequently may feel weak. Exercise can cause them, but most athletes who experience them have no heart or health issues. PVCs could show up in tests like 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 examine the heart.

A doctor is often able to tell whether a patient has PVCs by looking at them and taking a medical history. However, sometimes they will only notice them while examining the patient for different reasons, like following an accident or surgery. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias, and could be utilized in the event of any suspicion of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all you need. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine, and over the drug decongestants and reducing stress may help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also help reduce the frequency of PVCs. If your symptoms continue or are severe, speak to your doctor about possible treatments that could help control the symptoms.

Treatment

If PVCs don't cause symptoms or occur rarely, they usually don't need treatment. If you are frequently affected or frequently, your doctor may wish to look for other heart conditions and suggest lifestyle changes or medicine. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

When you have PVCs the electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. PVCs are more prevalent among people with heart problems, but it's not known what causes them. PVCs can become more frequent as you age, and could be more frequent during exercise.

If a patient is experiencing frequent and painful PVCs doctors should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor may also perform an exercise stress test to determine if the increased heartbeats are related to physical exercise. To find out whether there are other reasons for the extra beats, a heart catheterization or a cardiac MRI is possible.

The majority of people with PVCs have no complications and can live a normal life. They could increase your risk for heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some instances, this means the heart muscle gets weaker and has trouble pumping blood through your body.

A healthy and balanced diet and a lot of exercise can reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of caffeine and tobacco. It is also important to get enough sleep and manage stress. Some medicines may also increase your risk of getting PVCs. If you are taking any of these medicines, it is important that you follow your doctor's advice regarding eating a healthy diet and exercising as well as taking your medication.


Studies of patients with an excessive amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. Some people may need an organ transplant.
