How a VC Can Affect Your Heart

Many people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The heart's rhythm is usually controlled by a group of fibers that are located in the upper right-hand part 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 in a part called the sinus node (also known as the sinoatrial node or SA node) doesn't. Instead, the impulse starts in another area of your heart, the ventricles, and causes an untimed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat or is like it's fluttering. They may occur infrequently without causing any symptoms, but they could be frequent enough to impact your quality of life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor might treat them with medication.

In most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Over time, repeated PVCs can weaken the heart muscle. This is particularly true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.

PVCs can cause symptoms such as a feeling of your heart beating one beat, or even fluttering. You might also feel breathless. The fluttering could be more evident when you exercise or consume certain drinks or food items. People who experience chronic anxiety or stress may have more PVCs, and some medications such as amiodarone, digoxin and cocaine can increase the likelihood of developing them.

If you experience occasional PVCs Your doctor may recommend lifestyle changes and medicines. If they are a regular occurrence, you may need to avoid certain foods and beverages like alcohol and caffeine. You can also lessen your stress levels by getting enough sleep and working out.

If you have a lot of PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. This is done by a specialist known as an electrophysiologist. The treatment is usually effective in treating PVCs which reduce symptoms, but it does not stop them from becoming recurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib) which can lead to stroke. It is not common however it could be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs can cause your heart to skip or flutter. These heartbeats can be harmless, but you should talk to your Upvc doctor near me when you experience frequent episodes or symptoms like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node, located in the upper right side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles contract to pump blood into the lung. They return to the center to begin the next cycle of pumping. However, a PVC starts at a different spot that is separate from the bundle of fibers, known as the Purkinje fibers in the lower left part of the heart.

When PVCs happen, the heart may feel like it is racing or pounding. If you only have just a few episodes and there are no other symptoms the cardiologist will likely not be able to treat you. If you've got a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. He or she might also suggest wearing a Holter Monitor that records your heartbeat and tracks the number of PVCs.

People who have had a prior heart attack or suffer from cardiomyopathy -an illness that affects the way that the heart pumps blood -and should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, reducing anxiety and stress and getting enough rest. A cardiologist may prescribe medications to slow heartbeat, such as beta blockers.

If you are experiencing frequent PVCs even if don't have any other symptoms you should see a cardiologist. These irregular heartbeats could indicate a problem in the structure of your lungs or heart, and if they happen often enough, they can weaken your heart muscle. Most people who suffer from PVCs do not have any problems. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can feel like fluttering or skipped heartbeats, especially when they are frequent or intense. People who experience them frequently may feel faint. They can also happen with exercising, but most athletes who suffer from them don't have any problems with their health or heart. PVCs can show up on tests such as an electrocardiogram or Holter monitor. These are sticky patches that have sensors that record electrical impulses coming from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.

Often, a doctor will be able to determine if a person has PVCs from a patient's history and physical examination. Sometimes, they may only notice them while examining the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias and could be utilized if there's any concern of cardiac disease.

If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as decreasing stress can help. Regular exercise, maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or severe, speak to your upvc window doctor about medication that may be able to reduce the symptoms.

Treatment

If PVCs do not cause any symptoms or occur rarely generally, they don't require treatment. If they occur frequently your doctor may need to examine for heart problems or suggest lifestyle adjustments. You could also have an intervention to get rid of them (called radiofrequency catheter ablation).

If you have PVCs the electrical signal that triggers your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right corner of your heart. This could cause your heart to feel like it skips beats or has extra beats. They're more common among people who suffer from heart issues however, it's not clear what causes them. PVCs are more frequent as we age and can occur more frequently during exercises.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also perform an exercise stress test in order to determine if the additional heartbeats are related to physical exercise. To find out if there are other causes for the extra beats the heart catheterization or cardiac MRI is possible.

Most people who suffer from PVCs do not suffer from any issues and can live an ordinary life. They can increase your risk for heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some instances, this means the heart muscle gets weaker and has trouble pumping blood throughout your body.

Regular exercise and a balanced diet can lower the risk of developing PVCs. Avoid foods high in sodium and fat, and limit your consumption of tobacco and caffeine. It is also important to sleep enough and reduce stress. Some medicines can also increase the risk of getting PVCs. If you're taking one of these drugs it's crucial to follow your doctor's recommendations regarding eating healthy, exercising and taking your medication.

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