How a VC Can Affect Your Heart

PVCs are common and can be experienced by many people without causing any issues. If they are frequent, PVCs may weaken your heart and increase the chance of suffering from heart failure.

A bundle of fibers located in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) typically controls your heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers, or ventricles.

Causes

PVCs occur when the electrical impulse that normally begins your heartbeat at a point called the window doctors sinus node (also called the sinoatrial or SA Node) doesn't. Instead, the impulse is generated in a different area of your heart called the ventricles and triggers an untimed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart beats faster or feels fluttering. They may occur infrequently and not cause any symptoms, but they could be frequent enough to affect your quality of life. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor might treat them with medication.

In most people, PVCs are harmless and don't increase your risk of heart disease or other health issues. Regular PVCs, however, can weaken your heart muscle over time. This is particularly when the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can cause symptoms, such as a sensation of your heart beating a beat, or fluttering. You might also feel exhausted. The fluttering can be more noticeable when you exercise or have certain foods or drinks. PVCs are more common for those who suffer from chronic anxiety or stress. Certain drugs, like digoxin, amiodarone and cocaine, may increase the risk.

If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medication. If you are prone to frequent PVCs, your physician may recommend that you avoid certain drinks and foods, such as alcohol and caffeine. You can also take steps to lessen your stress levels, and make sure you get enough sleep and exercise.

If you have a lot of PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation, which destroys cells that cause PVCs. This is done by a specialist, known as an electrophysiologist. The treatment is typically successful in treating PVCs and reducing symptoms, but does not prevent them from returning in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib), which can lead to stroke. It's not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, can make your heart appear to flutter or skip one beat. These extra heartbeats are generally harmless, but it is important to consult your physician when you experience frequent episodes or other symptoms such as dizziness or weakness.

Normally, electrical signals begin in the sinoatrial node, located in the upper right portion of the heart. These signals descend to the lower chambers (or ventricles) which pump blood. The ventricles then contract to push the blood into the lung. They then return to the center to start the next cycle of pumping. A pvc doctor begins at a different spot in the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs occur, the heart may feel as if it's racing or pounding. If you have only just a few episodes and no other symptoms are present, your cardiologist will probably not treat you. However, if you have number of PVCs, the doctor may recommend an electrocardiogram, or ECG to determine the heart's rate over 24 hours. He or she might also suggest wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -which alters the way the heart pumps blood -and must be aware of their PVCs and speak with a cardiologist about lifestyle changes. This includes 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 the heartbeat.

Even if you don't experience any other signs, you should still get PVCs examined by an cardiologist if they occur frequently. These extra heartbeats may indicate a problem in the structure of your heart or lungs, and if they occur frequently enough, it could weaken the heart muscle. But most people suffering from PVCs don't experience any problems. They would like to know if fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs can be akin to 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 cause PVCs, but a lot of athletes who suffer from them have no 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 might also use an echocardiogram that uses ultrasound to look at the heart and see how it's functioning.

A doctor can often tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes however, they might not be aware of PVCs until they examine the patient for another reason such as following an accident or a surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect cardiac disease in the event of any reason to be concerned.

If your cardiologist concludes that your heart is structurally healthy, reassurance may be all that's needed. If your symptoms are causing discomfort or cause you to feel anxious, staying away from alcohol, caffeine and other decongestants as well as reducing stress levels can aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are extreme, talk to your doctor about possible treatments that could help control them.

Treatment

If PVCs are rare or do not cause symptoms, they do not usually require treatment. If you experience them frequently and frequently, your doctor might want to examine for any other heart problems and suggest lifestyle changes or medicine. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate them.

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can cause your heart to feel as if it skips a beating or has extra beats. PVCs are more frequent among those who suffer from heart issues, but it's not known the reason behind them. PVCs can increase in frequency as you age, and may occur more often during exercising.

A physician should perform an ECG and an echocardiogram on a patient who suffers from frequent and painful PVCs to identify structural heart conditions. The doctor may also perform an exercise stress test to determine if the additional heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be done to look for other reasons for the extra beats.

The majority of people with PVCs don't experience any issues and can live an ordinary life. However, they can increase the risk of developing dangerous heart rhythm issues, especially if you have certain patterns of them. In some cases, that means that your heart muscle gets weaker and has trouble pumping blood through your body.

A regular, healthy diet and plenty of exercise can help reduce your risk of developing PVCs. You should avoid foods that are high in sodium and fat and limit caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Certain medicines can also increase your risk of PVCs. If you are taking one of these drugs it is important to follow the upvc doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients with Pvc doctor burdens that are high (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. This can lead to the need for a heart transplant in some patients.
