Pvc Doctor: The History Of Pvc Doctor In 10 Milestones
How a VC Can Affect Your Heart

Many people experience occasional PVCs without any problems. If they occur often, PVCs may weaken your heart and increase the chance of suffering from heart failure.

A bundle of fibers located in the upper right part of your heart (the sinoatrial, or SA, node) typically regulates the heart's rhythm. Electrical signals travel from there to the lower chambers of your heart, or ventricles.

Causes

PVCs happen when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat or feels like it is fluttering. They can happen infrequently and not cause any symptoms, or they may occur frequently enough to interfere with your daily life. Your doctor might prescribe medication if they are frequent or cause dizziness, weakness or fatigue.

In most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. Regular PVCs however, could weaken your heart muscle over time. This is particularly the case if they are caused by a heart-related condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.

The signs of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering can be more noticeable when you exercise, or consume certain beverages or foods. PVCs are more prevalent in people with chronic stress or anxiety. Certain drugs, like digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.

If you experience occasional PVCs, your doctor may recommend lifestyle changes and medicines. If they're a frequent occurrence, you may have to stay clear of certain foods and beverages, such as caffeine and alcohol. You can also lessen stress by having enough sleep and working out.

If you have a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. The treatment is typically effective in treating PVCs which reduce symptoms, but it does not stop them from recurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib), an illness that can cause stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contracts or PVCs may cause your heart to skip or be fluttering. These heartbeats can be harmless, but you should consult your physician in case you experience frequent episodes or signs like dizziness or weakness.

Normally, electrical signals start at the sinoatrial junction, located in the upper right portion of the heart. These signals descend to the lower chambers (or ventricles) which pump blood. The ventricles then contract to pump blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC starts in a different place and is located in the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur they can make the heart feel like it is beating faster or slower. If you experience a few episodes and no other symptoms, your cardiologist probably won't treat you. If you have a lot of PVCs, your doctor may recommend that 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, which records the heart's rhythm and count the number of PVCs.

People who have suffered previously from a heart attack or cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs very seriously and speak to a cardiologist about lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist may prescribe medications to slow the heartbeat, for example, a beta blocker.

If you are experiencing frequent PVCs even if do not have other symptoms you should see an expert in cardiology. 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 could weaken the heart muscle. Most people who suffer from PVCs do not have any problems. the window doctor want to know that the fluttering or racing heartbeats aren't normal.


Diagnosis

PVCs might appear to be fluttering or skip heartbeats, especially when they're frequent or intense. People who experience them regularly may feel weak. Exercise can trigger them, but many athletes who experience these symptoms do not have heart or health problems. PVCs may show up on tests such as an electrocardiogram or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.

Often, a doctor will be able to identify if someone is suffering from PVCs from a patient's history and physical exam. Sometimes, they may not be aware of them until they examine the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They may be used to detect heart disease when there is a concern.

If your cardiologist concludes that your heart's structure is normal, reassurance will be the only treatment needed. If your symptoms are causing you discomfort or make you be anxious, avoiding alcohol, caffeine, and over the prescription decongestants, as well as decreasing stress can help. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or severe, speak to your doctor about medication that could help reduce the symptoms.

Treatment

If PVCs do not cause any symptoms or occur rarely, they usually don't need treatment. If you are frequently affected, your doctor may want to examine for other heart issues and recommend lifestyle changes or medications. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that creates your heartbeat is located other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can make it feel like your heart skips a beat or has extra beats. It's not known what causes these, but they're more common in people who have other heart problems. PVCs are more likely to occur as you age, and they might occur more frequently during exercising.

If a patient has frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor may also conduct an exercise stress test to determine if the extra heartbeats are due to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes for the additional beats.

Most people who suffer from PVCs do not suffer from any problems and can enjoy an ordinary life. They may increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases this means that the heart muscle becomes weaker and has difficulty pumping blood throughout the body.

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

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced myopathy in the heart was observed. Some people may need an organ transplant.
