How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. 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 your heart rhythm. Electrical signals travel from there to the lower heart chambers or ventricles.

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) does not. The impulse actually begins in the ventricles, causing an untimed heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They may happen rarely and cause no symptoms, or they can occur frequently enough to impact your quality of life. If they are very frequent or cause dizziness, weakness or fatigue, your doctor may treat them with medicine.

PVCs are generally safe and do not increase your risk of developing heart disease. In time, repeated PVCs can weaken the heart muscle. This is especially true if they are caused by a heart condition such as dilated cardiomyopathy or Stained glass window repair arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.

PVCs can trigger symptoms such as a feeling of your heart skipping a beat, or stained glass porthole window repair repair (links.musicnotch.Com) the feeling of your heart fluttering. You may also feel exhausted. The fluttering may be more evident when you exercise or consume certain foods or drinks. People who experience chronic anxiety or stress can have more PVCs, and some medications such as amiodarone, digoxin, and cocaine can increase the likelihood of developing them.

If you experience occasional PVCs your doctor might suggest lifestyle changes and medication. If you have frequent PVCs, your doctor may recommend that you avoid certain drinks and foods, like caffeine and alcohol. You can also take steps to reduce your stress levels, and get plenty of sleep and exercise.

If you've got a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is generally successful 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 having atrial fibrillation (AFib), which can result in stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractures, or PVCs can cause your heart to skip or flutter. These heartbeats can be harmless, however, you should consult your physician when you experience 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. They travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles expand to push blood into your lungs, and then return to the heart to start the next cycle of pumping. However, a PVC starts in a different place, from the bundle of fibers called the Purkinje fibers, in the lower left part of the heart.

When PVCs occur, they can make the heart beat or feel like it skipped a beat. If you experience just a few episodes but no other symptoms, the cardiologist probably won't treat you. But if you have a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG, to measure your heartbeat over 24 hours. The doctor may also recommend wearing a Holter monitor that records your heart rhythm over time, allowing you to see the number of PVCs you have.

Anyone who has suffered a heart attack in the past or have cardiomyopathy -- a condition that alters the way the heart pumps blood -and must be aware of their PVCs and consult a cardiologist about changes to their lifestyle. This includes abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat, such as beta blockers.

If you experience frequent PVCs even if you do not have other symptoms you should see a cardiologist. 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 the heart muscle. But most people suffering from PVCs do not experience any issues. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be akin to heartbeats that flutter, especially if they are frequent and intense. Patients who have a lot of them might feel like they're about to faint. They can also occur during exercising, but most athletes who suffer from them don't have any problems with their health or heart. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.

A doctor can often 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 an accident or surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They are able to identify cardiac problems when there is a concerns.

If your cardiologist concludes that your heart is structurally healthy, reassurance may be all that's needed. However, if your symptoms are causing discomfort or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your doctor about medications that could be able to manage the symptoms.

Treatment

If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If they happen frequently your doctor may need to examine for heart problems or suggest lifestyle modifications. You could also undergo a procedure (called radiofrequency cathode ablation) to eliminate of them.

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node located in the upper right corner of your heart. This could cause your heart to feel like it skips beats or has extra beats. They're more common among people with heart problems however it's unclear the reason behind them. PVCs may increase in frequency with age and might happen more frequently during exercises.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely conduct an exercise stress test in order to determine if the additional heartbeats are due to physical exercise. To determine if there are other causes for the extra beats, a heart catheterization or an MRI could be conducted.

Most people with PVCs don't experience any problems and can enjoy a normal lifestyle. They may increase the risk of developing dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.

A healthy, regular diet and plenty of exercise can help reduce your chances of developing PVCs. Avoid foods high in fat and sodium and limit your intake of tobacco and caffeine. Sleep and stress are also crucial. Some medicines can also increase the risk of getting PVCs. So if you take one of these medications it's crucial to follow your doctor's instructions about eating well, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. This could lead to the need for a heart transplant in some patients.
