How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by many people with no cause for concern. 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 regulates the heart's rhythm. Electrical signals travel to ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that typically initiates your heartbeat in a region called the sinus node (also called the sinoatrial or SA Node) isn't. The impulse actually begins in the ventricles, which causes a mistimed heartbeat. These extra beats, called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat or feels like it is fluttering. They may occur infrequently and not cause any symptoms, but they can occur frequently enough to impact your quality of living. If they happen frequently or cause weakness, dizziness or fatigue, your doctor could treat them with medication.

For the majority of people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is particularly true if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.

PVCs can cause symptoms, such as a sensation of your heart racing an beat, or the feeling of your heart fluttering. You may also feel exhausted. The fluttering can be more noticeable when you exercise or consume certain drinks or foods. PVCs are more common for those who suffer from chronic anxiety or stress. Certain medications, like digoxin, apartment window repair amiodarone or cocaine, may increase the risk of developing PVCs.

If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medication. If they're a frequent occurrence, you may have to avoid some 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've got a lot of 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. It is generally successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from recurring in the future. In certain cases it can increase your risk of having atrial fibrillation (AFib), which can lead to stroke. This isn't common but it could be life-threatening.

Symptoms

Premature ventricular contractions or PVCs, may make your heart seem to skip or flutter one beat. These extra heartbeats are usually harmless, but it is important to consult your physician if you have frequent episodes or signs like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node which is in the top right portion of the heart. These signals descend to the lower chambers (or ventricles) which pump blood. The ventricles then contract to pump blood into the lungs. They then return to the center to start the next cycle of pumping. A PVC begins in a different location, the Purkinje fibers are located in the left side of the heart.

When PVCs occur, the heart may feel as if it's skipping a beat or pounding. If you experience only one or two episodes, and no other symptoms are present your cardiologist may not be able to treat you. If you have a lot of PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor that records the heart's rhythm and count the number of PVCs.

Anyone who has suffered an earlier 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 about lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't experience any other indications, you should still get PVCs checked by an cardiologist if they occur frequently. These heartbeats that are irregular could be a sign of a problem with the structure of your heart or lungs, and if they happen often enough, can weaken the heart muscle. Most people who suffer from PVCs do not experience any issues. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who get lots of them may feel they're going to faint. They can also occur during exercising, but most athletes who get them don't have any problems with their health or heart. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. They use sticky patches with sensors on them to record electrical impulses from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to study the heart and determine how it's functioning.

A doctor is often able to tell if a patient has PVCs by examining them and taking their medical history. However, sometimes they will only be able to detect them when they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and they might be used when there is a concern of heart disease.

If your cardiologist determines that your heart's structure is normal, reassurance will be the only treatment needed. However, if your symptoms are causing discomfort or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can aid. Regular exercise, being at a healthy weight and drinking enough water can decrease the likelihood of PVCs. If your symptoms persist or are severe, talk to your doctor about possible treatments that could help control these symptoms.

Treatment

If PVCs are rare or do not cause symptoms, they rarely need treatment. If they happen frequently, your doctor might want to check for heart issues or suggest lifestyle changes. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them.

If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This could cause your heart to feel like it skips beats or has additional beats. PVCs are more prevalent among people who suffer from heart issues however it's unclear the reason behind them. PVCs are more frequent with age and might happen more often during exercising.

If a patient has frequent and office Window Repair painful PVCs, a physician should conduct an ECG and an echocardiogram to rule out heart disease that is structural. They may also perform an exercise stress test to determine whether the additional beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other causes for the additional beats.

The majority of people who suffer from PVCs don't experience any issues and can live an ordinary life. 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 throughout your body.

Regular exercise and a healthy diet can lower your chances of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of tobacco and caffeine. You should also try to get enough sleep and manage stress. Some medicines can also increase the risk of getting PVCs. If you're taking one of these medicines it is important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication.

In studies of patients suffering from PVC burdens that are high (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. Some patients may require a heart transplant.
