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 chance of suffering from heart failure.

The rhythm of your heart is usually controlled by a bundle of nerve fibers situated in the upper right-hand corner 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 are caused by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, which causes a mistimed heartbeat. These extra beats, called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat or feels fluttering. They may occur infrequently without causing any symptoms, but they could also happen frequently enough to affect your quality of living. Your doctor may prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. Regular PVCs, however, can weaken your heart muscle over time. This is especially relevant if they are triggered by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

PVCs can trigger symptoms such as a feeling of your heart skipping a beat, or fluttering. You may also feel breathless. The fluttering may be more noticeable if you exercise, or consume certain foods or beverages. PVCs are more common in people with chronic anxiety or stress. Some drugs, like digoxin, Glazing Doctor amiodarone, and cocaine, may increase the risk of developing PVCs.

If you experience occasional PVCs your pvc doctor might suggest lifestyle changes and medication. If you have frequent PVCs, your doctor may recommend avoiding certain drinks and foods, such as caffeine and alcohol. You can also take steps to lessen your stress and take advantage of plenty of rest and exercise.

If you have many PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is generally effective in treating PVCs which reduce symptoms, but does not prevent them from returning in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can result in stroke. It is not common but it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, may make your heart seem to skip or flutter a beat. These extra heartbeats are generally harmless, however, you should talk to your doctor if you have frequent episodes or symptoms like dizziness or weakness.

The electrical signals typically begin in the sinoatrial node located in the top right side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles expand to force blood into the lung. They return to the heart's center to start the next cycle of pumping. A pvc doctor begins at a different spot that is the Purkinje fibers are located in the left side of the heart.

When PVCs occur, they make the heart beat faster or feel like it skipped a beat. If you only have just a few episodes and no other symptoms are present the cardiologist will likely not be able to treat you. If you have a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. He or she might also suggest wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

Anyone who has suffered a previous heart attack or cardiomyopathy, an illness that affects the method by which the heart pumps blood - should take their PVCs very seriously and speak to a cardiologist regarding lifestyle modifications. This includes abstaining from alcohol, caffeine and smoking, reducing anxiety and stress and ensuring adequate sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other symptoms it is still recommended to have PVCs checked 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 happen often enough, they can weaken the heart muscle. Most people with PVCs don't experience any issues. They would like to know if fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs may feel like heartbeats that flutter, particularly if they're frequent and intense. People who experience a lot of them may feel they're going to faint. Exercise can trigger them, but many athletes who experience them do not have heart or health issues. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. They use sticky patches with sensors to record electrical signals from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.

A windows doctor will usually be able to determine if a patient has 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 after an accident or surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They can be used to detect heart disease in the event of any concern.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough fluids can reduce your episodes of PVCs. If your symptoms persist or are severe, talk to your doctor about possible medications that can control them.

Treatment

If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If they are frequent your doctor may want to check for heart issues or suggest lifestyle modifications. You could also have a procedure (called radiofrequency cathode ablation) to get rid them.

If you have PVCs in your heart the electrical signal that creates your heartbeat is located outside of the sinoatrial (SA) node located in the upper right corner of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. They're more common among people with heart problems, but it's not known the reason behind them. PVCs can become more frequent as you age, and could be more frequent during exercise.

A doctor should conduct an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to see if the extra beats are caused by physical activity. To determine whether there are other reasons for the extra beats an invasive heart catheterization or an MRI could be conducted.

The majority of people who suffer from PVCs are not affected and can live a normal life. However, they can increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

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

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