How a VC Can Affect Your Heart

Many people have occasional PVCs with no problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is usually controlled by a bundle of fibers that are located in the upper right corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower chambers of your heart or ventricles.

Causes

PVCs occur by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. Instead, the impulse starts in a different part of your heart, the ventricles, and causes an untimed beat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. They may feel like the heart beats faster or feels like it is fluttering. They can happen infrequently and cause no symptoms, or they may occur frequently enough to impact your daily life. Your doctor might prescribe medication if they are frequent or cause dizziness, weakness or fatigue.

PVCs are generally harmless and do not increase your risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is especially true if they are caused 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 sensation of your heart beating a beat, or the feeling of your heart fluttering. You might also feel exhausted. The fluttering could be more evident when you exercise, or eat or drink certain beverages or foods. People who experience chronic anxiety or stress may have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the risk of developing them.

If you are experiencing occasional PVCs your doctor may recommend lifestyle changes and medications. If they are a regular occurrence, you may have to avoid certain foods and beverages, such as caffeine and alcohol. You can also reduce your stress levels, and get plenty of sleep and exercise.

If you're experiencing many PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation. This eliminates the cells that cause PVCs. This is done by a specialist called an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib) which is a condition that can lead to stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to skip or flutter one beat. These extra heartbeats are usually harmless, however, you should consult your physician if you have frequent episodes or symptoms like dizziness or weakness.

The electrical signals normally begin in the sinoatrial area, which is located in the upper right part of the heart. They then travel to the lower chambers, or ventricles, which pump blood. The ventricles expand to pump blood into the lungs. They return to the heart's center to start the next cycle of pumping. A PVC begins in a different location that is the Purkinje fibers are located in the left side of the heart.

When PVCs occur and the heart is affected, it may feel like it is beating faster or slower. If you experience a few episodes and window seal replacement no other symptoms, the doctor will probably not treat you. But if you have a large number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG to determine the heart's rate over the course of 24 hours. They may also recommend wearing a Holter monitor that records your heartbeat over time to determine how many PVCs you have.

If you've had a prior heart attack or have cardiomyopathy -- a condition that alters the way the heart pumps blood -- should be aware of their PVCs and speak with a cardiologist about changes to their lifestyle. These include abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist can also prescribe medication to slow the heartbeat such as a beta blocker.

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

Diagnosis

PVCs can be akin to heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them might feel like they're about to faint. They can also occur during exercise, though many athletes who get them do not have any issues with their health or heart. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. They use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to study the heart and determine how it's working.

A doctor may be able to tell whether the patient is suffering from PVCs from a patient's history and physical exam. Sometimes, however, they may not be aware of PVCs until they examine a patient for another reason such as following an accident or a surgery. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias and can be used in the event of any suspicion of a cardiac condition.

If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment needed. However, if your symptoms are causing discomfort or cause you to feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms are persistent or extreme, consult your doctor about medications that could help control them.

Treatment

If PVCs do not cause any symptoms or happen rarely generally, they don't require treatment. If you experience them frequently, your doctor may want to examine for any other heart problems and recommend lifestyle changes or medication. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate them.

If you have 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 it to feel like your heart skips beats or has a few extra beats. PVCs are more prevalent among people with heart problems however, casement window repair it's not clear what causes them. PVCs are more likely to occur as you age, and may be more frequent during exercise.

A doctor should conduct an ECG as well as an echocardiogram on a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely conduct an exercise stress test in order to determine if the increased heartbeats are related to physical activity. To determine whether there are any other causes for the extra beats an invasive heart catheterization or cardiac MRI can be performed.

The majority of people who suffer from PVCs do not suffer from any problems and can enjoy a normal lifestyle. But they can increase the risk of developing dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases, Historic Window Repair that means that your heart muscle gets weaker and has trouble pumping blood through your body.

Regular exercise and a balanced diet can lower your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. Stress and sleep are also important. Certain medications can increase your risk of getting PVCs. If you're taking one of these medicines it is important to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

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