How a VC Can Affect Your Heart

A lot of people experience occasional PVCs without any problems. If they occur often, PVCs may weaken your heart and increase the risk of heart failure.

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

Causes

PVCs occur when the electrical impulse that typically begins your heartbeat in a part called the sinus node (also known as the sinoatrial node or SA node) isn't. The impulse actually starts in the ventricles, which causes a mistimed heartbeat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart beats faster or feels like it is fluttering. They can occur rarely without causing any symptoms, but they may be frequent enough to affect your quality of living. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medicine.

For the majority of people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. In time, repeated PVCs can weaken the heart muscle. This is especially the case if they are caused by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

PVCs can cause symptoms such as a feeling of your heart racing an beat, or the feeling of your heart fluttering. You may also feel breathless. The fluttering could be more apparent if you exercise, or consume certain beverages or foods. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs.

If you experience occasional PVCs your doctor might suggest lifestyle changes and medications. If they are a regular occurrence, you may have to avoid certain foods and beverages, such as caffeine and alcohol. You can also take steps to lessen your stress levels, and get plenty of sleep and exercise.

If you have a lot of PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation. This destroys cells that cause PVCs. Electrophysiologists are the ones who execute this procedure. It is typically successful in treating the PVCs and reducing symptoms however, it doesn't prevent them from occurring in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib), a condition that can lead to stroke. This isn't common, but it can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats can be harmless, but you might need to see your doctor in the event of frequent heartbeats or if you are experiencing symptoms like dizziness, or fatigue.

The normal electrical signals start in the sinoatrial region, which is in the upper right-hand part of the heart. They then travel to the lower chambers, also known as ventricles, that pump blood. The ventricles contract to propel the blood into your lungs and then return to the heart to start the next cycle of pumping. But a pvc Doctor (branch-leonard-4.Technetbloggers.de) starts in a different place, from the door doctor bundle of fibers, known as the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur, they cause the heart pound or feel as if it skipped one beat. If you have only one or two episodes, and there are no other symptoms the cardiologist will likely not be able to treat you. However, if you have large number of PVCs, the doctor may recommend an electrocardiogram, or ECG to determine your heartbeat over a 24-hour period. He or she might also suggest wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs.

People who have suffered a heart attack in the past or suffer from cardiomyopathy -- a condition that affects how the heart pumps blood -and must be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. These include avoiding alcohol, caffeine and smoking, managing stress and anxiety, and getting enough rest. A cardiologist may prescribe medications to slow the heartbeat, for example, beta blockers.

If you have frequent PVCs, even if you do not have any other symptoms you should see a cardiologist. These extra heartbeats can indicate an issue with the structure of your heart or other health issues, and over time, when they happen frequently enough, they could weaken the heart muscle. But most people suffering from PVCs don't experience any problems. They are interested in knowing if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering especially if they are frequent and intense. People who experience them often may feel weak. Exercise can cause PVCs, but a lot of athletes who experience these symptoms do not have heart or health problems. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which uses ultrasound to look at the heart and determine how it's functioning.

A doctor can often tell if a patient has PVCs by looking at them and taking a medical history. Sometimes, however, they may not be aware of PVCs until they examine a patient for another reason, like following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to identify cardiac problems when there is a reason to be concerned.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are troubling, or cause you to feel anxious, staying away from alcohol, caffeine and other over the drug decongestants and reducing stress may aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms persist or extreme, consult your physician about the medications that may be able to manage the symptoms.

Treatment

If PVCs don't cause symptoms or are not frequent they aren't usually in need of treatment. If they happen frequently, your doctor might be able to look for heart problems or suggest lifestyle modifications. You could also have an operation (called radiofrequency cathode ablation) to get rid them.

If you suffer from PVCs The electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right part of your heart. This can cause your heart to feel as if it skips beats or has extra beats. It's not clear what causes these, but they're more frequent in those with other heart problems. PVCs may increase in frequency as we age and can occur more frequently during exercise.

If a patient is experiencing frequent and painful PVCs doctors should perform an ECG and an echocardiogram to rule out structural heart disease. They may also perform an exercise stress test to determine whether the extra beats are a result of physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study can be performed to find other causes for the increased beats.

Most people who suffer from PVCs don't experience any problems and can enjoy a normal lifestyle. They could increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In some instances, this means that the heart muscle gets weaker and is unable to pump blood throughout your body.

A healthy, regular diet and a lot of exercise can reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat, and you should also limit caffeine and tobacco. Stress and sleep are also crucial. Some medicines can also increase the risk of developing PVCs. If you take any of these medications, it is important to follow your doctor's advice regarding eating a healthy diet exercising, as well as taking your medication.

Studies of patients who had a high amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
