How a VC Can Affect Your Heart

Many people experience occasional PVCs without any problems. If they happen frequently, PVCs may weaken your heart and increase your chance of suffering from 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 known as the sinoatrial node, or SA. Electrical signals travel to ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse that typically starts your heartbeat at a point called the sinus node (also known as the sinoatrial or SA node) does not. Instead, the impulse begins in a different part of your heart, the ventricles, and causes a mistimed beat. These extra beats are called ventricular tachycardia or Condo Window repair ventricular fibrillation. It may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely, causing no symptoms, but they can occur frequently enough to affect your standard of life. If they are very frequent or cause dizziness, weakness, or fatigue, your doctor could treat them with medication.

PVCs are generally harmless and do not increase your risk of heart disease. 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.

The signs of PVCs include a feeling that your heart beats slower or is fluttering, and you feel breathless. The fluttering may be more evident when you exercise or have certain drinks or food items. People with 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 are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medication. If you experience frequent PVCs, your doctor may recommend that you avoid certain drinks and foods, such as alcohol and caffeine. You can also lower your stress by getting enough sleep and exercising.

If you have many PVCs, he may suggest a medical treatment called radiofrequency catheter ablation. It destroys cells that cause PVCs. This procedure is performed by a specialist called an electrophysiologist. The treatment is typically successful in treating PVCs, reducing symptoms but does not prevent them from becoming recurring in the future. In some instances, casement window crank repair it can increase your risk of atrial fibrillation (AFib) which can cause a stroke. This isn't common however it could be life-threatening.

Symptoms

Premature ventricular contracts, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats can be harmless, however you might need to see your doctor if they are frequent or if you notice symptoms like dizziness, or fatigue.

Normally, electrical signals begin in the sinoatrial node, which is in the top right-hand side of the heart. They descend to the lower chambers (or ventricles) that pump blood. The ventricles then expand to push blood into the lungs, and return to the heart and start the next pumping cycle. However, a PVC starts in a different place that is separate from the bundle of fibers called the Purkinje fibers, located 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 have only one or two episodes, and there are no other symptoms, your cardiologist will probably not be able to treat you. But if you have a number of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG, to measure your heartbeat over 24 hours. They might also recommend wearing a Holter monitor that records your heartbeat over time, allowing you to see how many PVCs you have.

People who have had a previous heart attack or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood- should be aware of their PVCs and consult an expert in cardiology about lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, managing stress and anxiety and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other indications, you should still get PVCs checked by a cardiologist if they happen often. These extra heartbeats may indicate a problem in the structure of your lungs or heart, and if they happen often enough, can weaken the heart muscle. The majority of people with PVCs don't experience any issues. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them regularly might feel faint. Exercise can trigger them, but many athletes who experience these symptoms do not have heart or health problems. PVCs can be detected in tests like an electrocardiogram, or Holter monitor. These use sticky patches with sensors that record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to examine the heart and observe how it's working.

A doctor is often able to tell whether a patient has PVCs by looking at them and taking a medical history. Sometimes, they may only notice them while examining the patient for different reasons, like following an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and they might be used in the event of any suspicion of heart disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance might be all that's needed. If your symptoms are bothersome, or cause you to be anxious, avoiding alcohol, caffeine, and over the counter decongestants, and the reduction of stress could help. Regular exercise, maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms persist or are severe, speak with your physician about possible medications that can control the symptoms.

Treatment

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

When you have PVCs, the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) in the top right corner of your heart. This can cause your heart to feel like it skips beats or has extra beats. PVCs are more frequent among those who suffer from heart issues however it's unclear what causes them. PVCs are more frequent with age and might happen more often during exercising.

If a patient has frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out structural heart disease. The doctor may also perform an exercise stress test in order to determine if the additional heartbeats are related to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be performed to find other causes of the increased beats.

The majority of people with PVCs do not experience any issues and can live a normal lifestyle. However, they may increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and has trouble pumping blood through your body.

A regular, healthy diet and a lot 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 important. Some medicines can also increase the risk of getting PVCs. If you take any of these medications it is crucial that you follow your doctor's recommendations regarding healthy eating and exercising as well as taking your medication.

In studies of patients suffering from PVC burdens that are high (more than 20% of total heartbeats) the higher rate of arrhythmia-induced myopathy in the heart was observed. This can lead to a need for a heart transplant in some patients.
