How a VC Can Affect Your Heart

A lot of people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

The heart's rhythm is controlled by a group of fibers located in the upper right-hand corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower chambers of your heart, or ventricles.

Causes

PVCs are caused when the electrical impulse that typically initiates your heartbeat in a part called the sinus node (also called the sinoatrial node or fit SA node) isn't. The impulse actually begins in the ventricles and causes an irregular heartbeat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beating or feels fluttering. They can happen infrequently and not cause any symptoms, or they can occur frequently enough to interfere with your quality of life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor might treat them with medication.

PVCs are generally safe and do not increase your risk of developing heart disease. Over time, frequent PVCs can weaken the heart muscle. This is particularly true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.

The signs of PVCs include a feeling that your heart beats slower or flutters, and you may feel exhausted. The fluttering could be more noticeable when you exercise or consume certain drinks or foods. People with chronic anxiety or stress can have more PVCs and certain drugs like amiodarone digoxin and cocaine can increase the likelihood of developing them.

If you experience occasional PVCs Your doctor may suggest lifestyle changes and medication. If they're a frequent occurrence, you may have to avoid some drinks and foods, Hopper Window Repair such as caffeine and alcohol. You can also reduce your stress levels by getting enough sleep and working out.

If you have a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is typically effective in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib), which can lead to stroke. It is not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or to flutter. These heartbeats that are not normal can be harmless, but you may need to see your doctor in the event of frequent heartbeats or if you are experiencing symptoms such as dizziness or fatigue.

Normally, electrical signals begin in the sinoatrial node, located in the upper right-hand side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to push the blood into the lung. They then return to the center to begin the next cycle of pumping. However, a PVC begins at a different spot and is located in 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 feel as if it's skipping a beat or pounding. If you experience only just a few episodes and no other symptoms are present the cardiologist will likely not be able to treat you. If you've got a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. They may also suggest wearing a Holter monitor that will track your heart rhythm over time, allowing you to see the number of PVCs you have.

People who have had a previous heart attack or suffer from cardiomyopathy -- a condition that alters the way the heart pumps blood- must be aware of their PVCs and speak with an expert in cardiology about lifestyle changes. Those include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and getting enough sleep. A cardiologist may prescribe beta blockers to slow down the heartbeat.

Even if there aren't any other signs however, you should have PVCs checked by an expert in cardiology if they occur often. These heartbeats that are irregular can point to a problem with the structure of your heart or other health conditions, and over time, if they occur often enough, they may weaken the heart muscle. Most people who suffer from PVCs do not have any problems. They want to know if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering especially if they are frequent and intense. People who experience them regularly may feel faint. Exercise can trigger them, but most athletes who experience them have no heart or Clerestory Window Repair health issues. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to examine the heart and observe how it's working.

Often, a doctor will be able to determine if the patient has PVCs through a medical history and physical examination. Sometimes, they may only notice them while examining the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to detect heart disease in the event of any concerns.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. If your symptoms are causing you discomfort, or cause you to feel anxious, avoiding alcohol, caffeine and other over the counter decongestants, and the reduction of stress could help. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can also reduce your episodes of PVCs. If the symptoms persist or are severe, talk to your doctor about possible treatments that could help control them.

Treatment

If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If they happen frequently your doctor may be able to look for heart conditions or recommend lifestyle modifications. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This could cause your heart to feel as if it skips beats or has extra beats. PVCs are more prevalent among people suffering from heart disease, but it's not known what causes them. PVCs can increase in frequency as you age, and may occur more frequently during exercising.

If a patient is experiencing frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also likely conduct an exercise stress test to determine if the increased heartbeats are related to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion studies can be conducted to determine other reasons for the additional beats.

Most people with PVCs don't experience any problems and can enjoy an ordinary life. They could increase the risk of developing 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 the body.

Regular exercise and replace a healthy diet can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium, and you should also restrict your intake of tobacco and caffeine. Stress and sleep are also crucial. Certain medicines can also increase the risk of developing PVCs. If you are taking any of these medicines it is crucial that you follow the advice of your doctor regarding eating a healthy diet exercising, as well as taking your medication.

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