How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

The heart's rhythm is usually controlled by a bundle of nerve fibers situated in the upper right-hand part of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel to lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse that normally begins your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA node) isn't. The impulse actually begins in the ventricles, causing an untimed heartbeat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can occur infrequently and have no symptoms or they can happen often enough to affect your quality of life. If they occur frequently or cause weakness, dizziness or fatigue, your doctor might treat them with medicine.

PVCs are generally safe and do not increase your risk of heart disease. Regular PVCs however, may weaken the heart muscle over time. This is particularly when the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.

The symptoms of PVCs include feeling like your heart beats faster or is fluttering, and you feel exhausted. The fluttering may be more evident when you exercise, or eat or drink certain foods or beverages. PVCs are more prevalent for those who suffer from chronic anxiety or stress. Certain drugs, like digoxin, amiodarone and cocaine, can also increase the risk.

If you experience occasional PVCs your upvc doctor might suggest lifestyle changes and medication. If you are prone to frequent PVCs, your physician may recommend avoiding certain foods and drinks such as caffeine and alcohol. You can also take steps to reduce your stress, and get plenty of sleep and exercise.

If you have many PVCs Your doctor window may suggest a medical procedure known as radiofrequency catheter ablation. It destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In some instances, it can increase the risk of developing atrial fibrillation (AFib), which can result in stroke. It is not common however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can make your heart appear to skip or flutter the beat. These heartbeats can be harmless, but it is important to consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness.

The normal electrical signals start in the sinoatrial area, which is located in the upper right-hand part of the heart. They then travel to the lower chambers, or ventricles, which pump blood. The ventricles then contract to pump blood into the lungs. They return to the heart's center to begin the next cycle of pumping. However, a Pvc Doctor starts in a different place, from the bundle of fibers called the Purkinje fibers, located in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may appear to be beating faster or slower. If you experience just a few episodes but no other symptoms, your glass doctor will probably not treat you. If you've got a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG to determine the heart's rate over 24 hours. They may also suggest wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

Anyone who has had a prior heart attack or have cardiomyopathy -which alters the way the heart pumps blood- should take their PVCs seriously and speak with an expert in cardiology about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you have frequent PVCs even if you do not have other symptoms you should see a cardiologist. These irregular heartbeats could indicate an issue with the structure of your heart or other health conditions and, over time, if they occur often enough, they can weaken the heart muscle. However, most people with PVCs do not experience any issues. They just want to be aware that the fluttering and racing heartbeats aren't normal.

Diagnosis

PVCs may appear to be fluttering or skip heartbeats, especially if they are frequent or intense. People who experience a lot of them may feel they're about to faint. They can also occur during exercise, though many athletes who suffer from them don't have any problems in their heart or health. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical signals from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.

Often, a doctor will be able to determine if someone has PVCs from a patient's history and physical exam. Sometimes, they may not be aware of them until 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 may be used to identify cardiac problems when there is a concerns.

If your cardiologist finds that your heart is structurally normal, reassurance is the only treatment needed. However, if your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress can aid. Getting regular exercise, staying at a healthy weight and drinking enough water can reduce your episodes of PVCs. If the symptoms persist or are extreme, talk with your physician about possible medications that can control the symptoms.

Treatment

If PVCs do not cause any symptoms or occur rarely, they usually don't need treatment. If you are frequently affected and frequently, your doctor might want to examine for other heart conditions and recommend lifestyle changes or medication. You could also have an operation (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This could cause it to feel like your heart skips beats or has a few extra beats. They're more common among people suffering from heart disease however, it's not clear what causes them. PVCs can become more frequent as you age, and might occur more frequently during exercising.

If a patient has frequent and painful PVCs doctors should perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also perform an exercise stress test to determine if the extra heartbeats are caused by physical exercise. To determine if there are other causes for the extra beats the heart catheterization or cardiac MRI could be conducted.

Most people who suffer from PVCs do not have any issues and can live a normal life. They may increase your risk for dangerous heart rhythm disorders particularly if they happen in certain patterns. In some cases, this means that the heart muscle becomes weaker and it is more difficult to pump blood throughout the body.

Regular exercise and a balanced diet will 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 the risk of developing PVCs. If you are taking any of these medicines it is essential that you follow your doctor's advice about eating healthy, exercising, and taking your medication.

Studies of patients suffering from a high amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. This can lead to the need for a transplant in some people.
