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

A lot of people experience occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

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

Causes

PVCs occur when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, causing an irregular heartbeat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart beats faster or feels like it is fluttering. They can occur infrequently and not cause any symptoms, or they can occur frequently enough to impact your quality of life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor may treat them with medication.

For the majority of people, PVCs are harmless and do not increase the risk of developing heart disease or other health problems. A lot of PVCs, however, can weaken your heart muscle over time. This is particularly relevant if they are triggered by a heart condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

The signs of PVCs include feeling like your heart beats slower or is fluttering, and you feel breathless. The fluttering could be more apparent when you exercise or consume certain drinks or foods. People who experience chronic anxiety or stress can have more PVCs and certain medications such as amiodarone, digoxin, and cocaine may increase the chance of developing them.

If you experience occasional PVCs your doctor might suggest lifestyle changes and medications. If you have frequent PVCs, your doctor might recommend that you avoid certain foods and drinks, such as alcohol and caffeine. You can also lower your stress levels by taking enough rest and working out.

If you have many PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. Electrophysiologists are the ones who execute this procedure. It is generally effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In certain cases it may increase your risk of having atrial fibrillation (AFib) which could lead to stroke. It is not common, but it can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, may make your heart appear to flutter or skip one beat. These heartbeats can be harmless, but it is important to consult your physician when you experience frequent episodes or symptoms like dizziness or weakness.

Normally, electrical signals start in the sinoatrial node, located in the top right side of the heart, and travel down to the lower chambers (or ventricles) which pump blood. The ventricles expand to force blood into the lungs. They then return to the center to start the next cycle of pumping. A PVC begins at a different spot, the Purkinje fibers are located in the left side of the heart.

When PVCs happen and the heart is affected, it may feel as if it's racing or pounding. If you experience only one or two episodes, and no other symptoms are present your cardiologist may not prescribe treatment. If you have many PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. The doctor may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has suffered previously from a heart attack or cardiomyopathy - a condition which affects the way the heart pumps blood - must take their PVCs seriously and consult an expert in cardiology about lifestyle modifications. This includes cutting down on caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist might also prescribe medication to slow heartbeat, such as beta blockers.

Even if there aren't any other symptoms, you should still get PVCs checked by a cardiologist if they happen frequently. These extra heartbeats may signal a problem with the structure of your lungs or heart, and if they occur often enough, they can weaken the heart muscle. Most people who suffer from PVCs don't experience any issues. They simply want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis


PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them regularly may feel faint. They can also happen with exercise, though many athletes who experience them don't have any problems in their heart or health. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.

A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history. Sometimes, they may not be aware of them until they examine the patient for different reasons, like after an accident or surgery. Ambulatory ECG monitoring systems also aid in detecting PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition.

If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment needed. If your symptoms are causing you discomfort or make you feel anxious, staying away from alcohol, caffeine and other over the drug decongestants and the reduction of stress could aid. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all aid in reducing the frequency of PVCs. If more information are persistent or extreme, consult your physician about the medications that could be able to manage these symptoms.

Treatment

If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If you have them often and frequently, your doctor might want to examine for other heart issues and recommend lifestyle changes or medicine. You could also have a procedure (called radiofrequency cathode ablation) to get rid of them.

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere outside of 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 a few extra beats. PVCs are more prevalent among people who suffer from heart issues however, it's not clear the reason behind them. PVCs are more likely to occur as you age, and they might occur more frequently during exercising.

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

The majority of people with PVCs are not affected and can lead the normal life. However, they may increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout your body.

Regular exercise and a healthy diet can lower the chances of developing PVCs. Avoid foods that are high in fat and sodium, and you should also reduce your intake of caffeine and tobacco. Also, you should try to get enough sleep and reduce stress. Some medicines may also increase your risk for PVCs. If you are taking any of these medications, it is important to follow your doctor's recommendations regarding healthy eating, exercising, and taking your medication.

Studies of patients suffering from 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. Some people may need a heart transplant.
