How a VC Can Affect Your Heart

PVCs are common and may be experienced by a variety of people without causing any issues. If they occur often, PVCs may weaken your heart and increase the risk for heart failure.

The heart's rhythm is 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 happen when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. Instead, the impulse is generated in a different area of your heart called the ventricles and triggers a wrongly timed beat. These extra beats, called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat, or it feels like it is like it is fluttering. They can occur infrequently and have no symptoms or they can occur frequently enough to affect your daily life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medicine.

PVCs are generally safe and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is particularly when the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.

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

If you have occasional PVCs your doctor may suggest lifestyle changes and medication. If you have frequent PVCs, your doctor may suggest that you stay away from certain foods and drinks, such as alcohol and caffeine. You can also take steps to reduce your stress and make sure you get enough sleep and exercise.

If you have many PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. This is done by a specialist known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms however it does not stop them from occurring in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib), a condition that can result in stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, can cause your heart appear to skip or flutter one beat. These extra heartbeats are harmless, however you might want to consult your bifold doctor in the event of frequent heartbeats or if you notice symptoms such as dizziness or fatigue.

The electrical signals normally begin in the sinoatrial area, which is located in the upper right corner of the heart. They then move to the lower chambers, or ventricles, that pump blood. The ventricles expand to push the blood into the lungs. They then return to the center to start the next cycle of pumping. But a Pvc Doctor begins at a different spot and is located in the bundle of fibers, known as the Purkinje fibers, in the lower left part of the heart.

When PVCs occur they can make the heart feel as if it's racing or pounding. If you have only a few episodes, but no other symptoms, your doctor will probably not treat you. If you've got a large number of PVCs, the doctor window may recommend an electrocardiogram, or ECG, to measure your heart rate over a 24-hour period. He or she might also recommend wearing a Holter monitor that records the heart's rhythm over time to see how many PVCs you have.

People who have suffered a heart attack in the past or have cardiomyopathy -which affects the way that the heart pumps blood - should take their PVCs seriously and consult a cardiologist about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, reducing stress and anxiety and ensuring adequate sleep. A cardiologist might prescribe medication to slow the heartbeat like a beta blocker.

Even if there aren't any other indications it is still recommended to have PVCs examined by a cardiologist if they happen often. These irregular heartbeats could signal a problem with the structure of your heart or lungs, and if they occur frequently enough, they can weaken your heart muscle. Most people with PVCs do not experience any issues. They would like to know if fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering 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 happen with training, even though many athletes who get them don't have issues with their health or heart. PVCs can show up in tests like an electrocardiogram or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to study the heart.

A doctor may be able to identify if a person is suffering from PVCs from a history and physical examination. However, sometimes they will not be aware of them until they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias, and can be used in the event of any suspicion of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance could be all that's needed. However, if your symptoms are bothersome or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms continue or are severe, talk with your physician about possible treatments that could help control these symptoms.

Treatment

If PVCs don't cause symptoms or are not frequent, they usually don't need treatment. If they occur frequently, your doctor might need to examine for heart issues or suggest lifestyle changes. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid them.

If you have PVCs, the electrical signal that triggers your heartbeat begins somewhere different than the sinoatrial nerve (SA node) in the top right part of your heart. This can make it feel like your heart skips beats or has a few extra beats. It's not known what causes them, but they're more common in people with other heart issues. PVCs can increase in frequency as we age and can occur more frequently during exercising.

If a patient is experiencing frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They should also conduct an exercise stress test to determine whether the extra beats are due to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study could be conducted to determine other causes of the additional beats.

The majority of people with PVCs have no complications and can lead an ordinary life. However, they may increase the risk of developing dangerous heart rhythm issues, especially if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.

Regular exercise and a balanced diet can lower the chances of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. Stress and sleep are also important. Some medicines can also increase your risk of PVCs. If you are taking any of these medications it is essential that you follow the advice of your doctor window about eating healthy exercising, as well as taking your medication.

Studies of patients suffering from a high amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some people may need an organ transplant.
