How a VC Can Affect Your Heart

A lot of people experience occasional PVCs and have no issues. If they occur often, PVCs may weaken your heart and increase your risk for heart failure.

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

Causes

PVCs are caused when the electrical impulse which normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They may happen rarely and not cause any symptoms, or they can happen often enough to impact your daily life. Your doctor may prescribe medicine when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally harmless and don't increase your risk of developing heart disease. A lot of PVCs, however, can weaken your heart muscle over time. This is particularly true if the PVCs are caused by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.

The symptoms of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering could be more apparent when you exercise or have certain foods or drinks. PVCs are more prevalent in people with chronic stress or anxiety. Certain medications, such as digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs.

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

If you have a lot of PVCs The doctor may recommend a medical treatment known as radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. The procedure is carried out by a specialist called an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms however it does not stop them from occurring in the future. In some instances it may increase your risk of atrial fibrillation (AFib), which can cause stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractures PVCs, also known as PVCs, can cause your heart to skip or to flutter. These extra heartbeats are harmless, but you may be advised to consult your physician if they are frequent or if you are experiencing symptoms like dizziness or fatigue.

Normaly, electrical signals begin in the sinoatrial region, which is in the upper right corner of the heart. They then travel to the lower chambers, also known as ventricles, that pump blood. The ventricles expand to force blood into the lungs. They return to the center to start the next cycle of pumping. A PVC starts in a different location that is the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel like it is beating faster or slower. If you've experienced only a few episodes, but no other symptoms, the doctor probably won't be able to treat you. If the window doctor have many PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat over the course of 24 hours. He or she might also recommend wearing a Holter monitor, which will record your heart rhythm over time to determine the number of PVCs you have.

If you've had a previous heart attack or suffer from cardiomyopathy -- a condition that affects the way that the heart pumps bloodand should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, reducing anxiety and stress and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs, even if you do not have any other symptoms you should see a cardiologist. These irregular heartbeats could indicate a problem in the structure of your heart or lungs and if they occur often enough, can weaken your heart muscle. The majority of people with PVCs do not have any issues. They just want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs can be akin to heartbeats that flutter, particularly if they're frequent and intense. People who experience a lot of them might feel like they're going to faint. Exercise can trigger PVCs, but a lot of athletes who experience them do not have heart or health issues. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to examine the heart and see how it's working.

A doctor can often tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes it is possible that they only notice PVCs when examining the patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and they might be used if there's any concern of heart disease.

If your cardiologist determines that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are bothersome or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible treatments that could help control them.

Treatment

If PVCs don't cause symptoms or occur rarely, they usually don't need treatment. If they occur frequently, your doctor might need to examine for heart problems or suggest lifestyle modifications. You could also have an operation (called radiofrequency cathode ablation) to get rid of them.





If you have PVCs in your heart the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This can cause your heart to feel like it skips a beating or has additional beats. PVCs are more frequent among those with heart problems however, it's not clear the reason behind them. PVCs may increase in frequency as you age, and they may be more frequent during exercises.

A doctor should conduct an ECG and an echocardiogram on a patient that suffers from frequent and painful PVCs to rule out structural heart diseases. They will probably also do an exercise stress test to see if the extra beats are a result of physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes of the increased beats.

Most people who suffer from PVCs don't experience any issues and can live a normal lifestyle. They may increase the risk of dangerous heart rhythm disorders, especially if they occur in certain patterns. In some cases, that means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

Regular exercise and a healthy diet can lower the risk of developing PVCs. Avoid foods that are high in fat and sodium and restrict your intake of tobacco and caffeine. You should also try to get enough sleep and manage stress. Certain medications can increase your risk for PVCs. If you take any of these medicines it is crucial that you follow your doctor's recommendations regarding eating a healthy diet and exercising as well as taking your medication.

In studies of patients suffering from high PVC burdens (more than 20% of the total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. This can lead to the need for a transplant in some people.
