One Key Trick Everybody Should Know The One Pvc Doctor Trick Every Person Should Learn
How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. If they occur often, PVCs may weaken your heart and increase your risk of heart failure.

A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial, or SA, node) typically controls your heart rhythm. Electrical signals travel to the ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that usually initiates your heartbeat at a point known as the sinus node (also called the sinoatrial or SA node) doesn't. Instead, the impulse begins in a different area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat or feels like it is fluttering. view may happen rarely and cause no symptoms, or they may occur frequently enough to interfere with your quality of life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medication.

PVCs are generally harmless and don't increase the risk of heart disease. Frequent PVCs however, may weaken the heart muscle over time. This is especially the case if they are caused by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.

PVCs can trigger symptoms, such as a sensation of your heart beating a beat, or fluttering. You may also feel exhausted. The fluttering can be more evident when you exercise, or consume certain drinks or foods. People who experience chronic anxiety or stress may have more PVCs and certain medications such as amiodarone, digoxin and cocaine can increase the likelihood of developing them.

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

If you've got a lot of PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who execute this procedure. It is generally successful in treating the PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases it can increase the risk of atrial fibrillation (AFib) which is an illness that can cause stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or be fluttering. These extra heartbeats are usually harmless, but it is important to talk to your doctor if you have frequent episodes or other symptoms such as dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles expand to pump blood into the lung. They return to the heart's center to start the next cycle of pumping. But a PVC starts in a different location, from the bundle of fibers, known as the Purkinje fibers, in the lower left part of the heart.

When PVCs occur, they cause the heart beat faster or feel as if it skipped one beat. If you experience a few episodes and no other symptoms, your doctor probably won't be able to treat you. If you have a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. They may also suggest wearing a Holter monitor, which will record your heart rhythm over time, allowing you to see the number of PVCs you have.

Anyone who has suffered previously from a heart attack or have suffered from cardiomyopathy - an illness that affects the heart's blood flow - should take their PVCs very seriously and speak to a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other indications it is still recommended to have PVCs checked by a cardiologist if they happen often. These extra heartbeats may indicate a problem in the structure of your heart or lungs, and if they occur often enough, can weaken your heart muscle. The majority of people with PVCs do not have any problems. They just want to be aware that the fluttering and racing heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that flutter, especially if they are frequent and intense. People who experience a lot of them might feel like they're about to faint. Exercise can trigger them, but many athletes who experience them do not have heart or health issues. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to look at the heart and see how it's working.

A doctor may be able to tell whether someone is suffering from PVCs through a medical history and physical exam. Sometimes it is possible that they not be aware of PVCs until they examine patients for a different reason such as following an accident or a surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and can be used when there is a concern of cardiac disease.

If your cardiologist determines your heart is structurally healthy, reassurance might be all you need. If your symptoms are bothersome or cause you to feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can all help reduce the frequency of PVCs. If your symptoms continue or are severe, talk to your doctor about medication options to treat these symptoms.


Treatment

If PVCs aren't common or don't cause symptoms, they don't usually require treatment. If they are frequent your doctor may be able to look for heart issues or suggest lifestyle changes. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid of them.

If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial (SA) node located in the upper right corner of your heart. This can 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 unclear the reason behind them. PVCs can become more frequent as you age, and they could be more frequent during exercising.

A physician should perform an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to identify structural heart conditions. They should also conduct an exercise stress test to see whether the additional beats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for other causes for the extra beats.

Most people who suffer from PVCs do not suffer from any complications and can lead a normal lifestyle. However, they can increase your risk of having dangerous heart rhythm issues, especially if you have certain patterns of them. In some cases this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.

A healthy and balanced diet and a lot of exercise can help reduce your chances of developing PVCs. Avoid foods that are high in sodium and fat, and you should also limit caffeine and tobacco. Sleep and stress are also important. Certain medicines can also increase the risk of developing PVCs. If you are taking one of these medications it's crucial to follow the doctor's advice about a healthy diet, exercise and taking your medication.

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