How a VC Can Affect Your Heart

Many people experience occasional PVCs with no problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.

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

Causes

PVCs happen when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, causing a mistimed heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or is like it's fluttering. They may occur infrequently and not cause any symptoms, but they could occur frequently enough to affect your quality of life. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor could treat them with medicine.

PVCs are generally harmless and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is particularly true if the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.

PVCs can trigger symptoms, such as a sensation of your heart racing one beat, or even fluttering. It is also possible to feel breathless. The fluttering may be more noticeable when you exercise or have certain foods or drinks. People who suffer from chronic stress or anxiety can have more PVCs, and some medications such as amiodarone, digoxin and cocaine can increase the chance of developing them.

If you have occasional PVCs Your doctor may recommend lifestyle changes and medicines. If you have frequent PVCs, your doctor may recommend avoiding certain drinks and foods, like caffeine and alcohol. You can also reduce your stress and make sure you get enough sleep and exercise.

If you have many PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. This destroys the cells that are responsible for PVCs. This procedure is performed by a specialist known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In some instances it can increase your risk of having atrial fibrillation (AFib) which could lead to stroke. It is not 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 extra heartbeats are usually harmless, but it is important to consult your physician if you have frequent episodes or signs like dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial region, which is in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles expand to push blood into your lungs, and then return to your heart and start the next pumping cycle. But a PVC begins in a different place that is separate from the bundle of fibers, known as the Purkinje fibers in the left-hand side of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped the beat. If you only have a few episodes, and there are no other symptoms, your cardiologist will probably not prescribe treatment. If you have a lot of PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat over the course of 24 hours. They may also recommend wearing a Holter Monitor which tracks the heart's rhythm and count the number of PVCs.

Anyone who has had a prior heart attack or have cardiomyopathy -which affects the way that the heart pumps blood- should take their PVCs seriously and speak with an expert in cardiology about lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, managing anxiety and stress and getting enough sleep. A cardiologist might also prescribe medication to slow the heartbeat such as a beta blocker.

If you have frequent PVCs, even if you do not have other symptoms you should see an expert in cardiology. These irregular heartbeats could indicate a problem in the structure of your heart or lungs, and if they happen often enough, can weaken your heart muscle. The majority of people with PVCs do not have any issues. They simply want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs can feel like fluttering or skipped heartbeats, especially if they are frequent or intense. Patients who have a lot of them may feel they're going to faint. They can also occur during training, even though many athletes who suffer from them do not have any issues with their heart or health. PVCs may show up in tests like an electrocardiogram or a Holter monitor. They use sticky patches with sensors that record electrical impulses from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to study the heart and see how it's working.

A doctor is often able to tell whether a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes, they may not be aware of them until they examine the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias, and they might be used when there is a concern of heart disease.

If your cardiologist determines your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are troubling or make you be anxious, avoiding alcohol, caffeine and other over the prescription decongestants, as well as reducing stress may help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also decrease the likelihood of PVCs. If your symptoms continue or are extreme, talk with your physician about possible treatments that could help control the symptoms.


Treatment

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

If you suffer from PVCs The electrical signal that causes your heartbeat is generated from a place other than the sinoatrial node (SA node) in the top right side of your heart. This could cause your heart to feel like it skips beats or has additional beats. It's unclear what causes these symptoms, but they're frequent in those with other heart problems. PVCs can increase in frequency with age and might happen more often during exercise.

If a patient has frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely perform an exercise stress test to determine if the increased heartbeats are due to physical exercise. To find out if there are other causes for the extra beats the heart catheterization or a cardiac MRI can be performed.

Most people with PVCs do not experience any issues and can live a normal lifestyle. They can increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In certain cases, it means that the heart muscle becomes weaker and is having difficulty pumping blood throughout your body.

A healthy and balanced diet and plenty of exercise can help reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. Sleep and stress are also crucial. Certain medications can increase the risk of getting PVCs. If you are taking one of these medications it is important to follow the doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was discovered. window doctor Repair My Windows And Doors can result in the need for a transplant in a few individuals.
