How a VC Can Affect Your Heart

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

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

Causes

PVCs are caused when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or feels like it's fluttering. They may happen rarely and not cause any symptoms, or they can occur frequently enough to affect your daily life. If they are very frequent or cause weakness, dizziness, or fatigue, your glazing doctor might treat them with medication.

For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Regular PVCs however, may weaken your heart muscle over time. This is particularly relevant if they are triggered by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

PVCs can cause symptoms like a feeling of your heart racing a beat, or fluttering. You may also feel breathless. The fluttering may be more apparent when you exercise or consume certain drinks or foods. People who suffer from chronic anxiety or stress may have more PVCs and certain drugs like amiodarone digoxin, and cocaine can increase the chance of developing them.

If you experience occasional PVCs your doctor may recommend lifestyle changes and medication. If they are a regular occurrence, you may have to stay clear of certain foods and beverages like alcohol and caffeine. You can also lessen your stress levels by taking enough rest and exercising.

If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is typically effective in treating PVCs and reducing symptoms, but it does not stop them from becoming recurring in the future. In certain cases, it may increase the risk of developing atrial fibrillation (AFib), which can cause stroke. This isn't common but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, may make your heart appear to skip or flutter the beat. These heartbeats that are not normal can be harmless, but you may want to consult your doctor in the event of frequent heartbeats or if you notice symptoms like dizziness, or fatigue.

Normally, electrical signals start at the sinoatrial junction, located in the upper right side of the heart. These signals travel down to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel blood into the lungs, and then return to your heart to begin the next pumping cycle. A pvc doctor (please click the next website page) begins in a different location that is the Purkinje fibers are located in the left side of the heart.

When PVCs occur, they cause the heart beat faster or feel as if it skipped the beat. If you have only a few episodes, but no other symptoms, your cardiologist probably won't treat you. If you've got a lot of PVCs the doctor may recommend an electrocardiogram, or ECG to gauge the heart's rate over 24 hours. He or she might also recommend wearing a Holter monitor that will track 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 -which affects how the heart pumps blood- must be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. This includes the avoidance of alcohol, caffeine, and smoking, reducing stress and anxiety and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs even if you do not have any other signs, you should see a cardiologist. These irregular heartbeats could signal a problem with the structure of your lungs or heart, and if they happen often enough, can weaken the heart muscle. But most people suffering from PVCs don't experience any problems. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them might feel like they're going to faint. They can also occur with training, even though many athletes who suffer from them don't have issues with their health or heart. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

Most of the time, a doctor will be able to tell whether a person has PVCs from a patient's history and physical examination. Sometimes it is possible that they not be aware of PVCs until they examine patients for a different reason, like following an accident or surgery. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias, and could be utilized in the event of any suspicion of cardiac disease.

If your cardiologist determines your heart is structurally healthy, reassurance may be all you need. However, if your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms persist or are severe, talk to your doctor about medication options to treat them.

Treatment

If PVCs do not cause any symptoms or happen rarely they aren't usually in need of treatment. If you are frequently affected, your doctor may want to check for other heart conditions and suggest lifestyle changes or medications. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.

When you have PVCs, the electrical signal that triggers your heartbeat is generated from a place different than the sinoatrial nerve (SA node) in the top right corner of your heart. This could cause it to feel like your heart skips beats or is beating faster. It's not known what causes them, but they're more common in people with other heart problems. PVCs are more likely to occur as you age, and they might occur more frequently during exercise.

A physician should perform an ECG as well as an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. They may also perform an exercise stress test to see whether the additional beats are due to physical activity. To determine whether there are other reasons for the extra beatings, a heart catheterization or a cardiac MRI could be conducted.

Most people with PVCs have no complications and can live the normal life. However, they can increase your risk of having dangerous heart rhythm problems, especially if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

A healthy and balanced diet and a lot of exercise can reduce your chances of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. It is also important to get enough rest and manage stress. Certain medications can increase your risk of PVCs. If you are taking one of these drugs it's crucial to follow the doctor's advice about eating well, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. Some people may need an organ transplant.
