How a VC Can Affect Your Heart

PVCs are common and may be experienced by many people with no cause for concern. If they happen frequently, 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) usually controls your heart rhythm. Electrical signals travel from this node to the lower chambers of your heart or ventricles.

Causes

PVCs happen when the electrical impulse which normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, which causes an irregular heartbeat. These extra beats are known as ventricular tachycardia, and ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They may happen rarely and cause no symptoms, or they may occur frequently enough to affect your quality of life. Your glass doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.

PVCs are generally safe window and door doctor do not increase the risk of heart disease. Over time, frequent PVCs can weaken the heart muscle. This is particularly true if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.

The signs of PVCs include feeling like your heart skips a beat or is fluttering, and you feel breathless. The fluttering could be more evident when you exercise or have certain drinks or foods. PVCs are more common for those who suffer from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, can also increase the risk of developing PVCs.

If you have occasional PVCs your doctor may recommend lifestyle changes and medications. If they are a frequent occurrence, you may have to avoid some foods and beverages like caffeine and alcohol. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise.

If you have a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells responsible for 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 occurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib), an illness that can lead to stroke. It is not common but it could be life-threatening.

Signs and symptoms

Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or to flutter. These heartbeats can be harmless, but you should consult your physician in case you experience frequent episodes or other symptoms such as dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial region, which is in the upper right corner of the heart. They then travel to the lower chambers, also known as ventricles, that pump blood. Then, the ventricles expand to push blood into your lungs, and then return to the heart to start the next cycle of pumping. But a PVC begins in a different location that is separate from the bundle of fibers called the Purkinje fibers, in the door doctor left-hand side of the heart.

When PVCs occur, they can make the heart beat faster or feel like it skipped one beat. If you've experienced only a few episodes, but no other symptoms, your cardiologist probably won't treat you. If you have a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. They might also recommend wearing a Holter monitor that records your heartbeat over time, allowing you to see the number of PVCs you have.

People who have suffered a previous heart attack or have suffered from cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs very seriously and speak to an expert in cardiology about lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.

If you are experiencing frequent PVCs, even if you do not have other symptoms, you should consult an expert in cardiology. These irregular heartbeats could be a sign of a problem with the structure of your heart or lungs and if they happen often enough, it could weaken the heart muscle. But most people suffering from PVCs don't have any issues. They simply want to know that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs may feel like heartbeats that are fluttering especially if they are frequent and intense. Patients who have a lot of them may feel they're going to faint. They can also occur with exercising, but most athletes who get them do not have any issues with their heart or health. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

Most of the time, a doctor will be able to tell whether someone has PVCs from a patient's history and physical examination. Sometimes, however, they may only be able to detect PVCs when they examine the patient for another reason, such as after an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs as well as other arrhythmias. They may be used to detect heart disease in the event of any concerns.

If your cardiologist concludes that your heart is structurally healthy, reassurance might be all you need. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine, and over the counter decongestants, and decreasing stress can help. Regular exercise, maintaining a healthy weight and drinking enough fluids can all aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your physician about the medications that could help control the symptoms.

Treatment

If PVCs don't cause symptoms or are not frequent, they usually don't need treatment. If they happen frequently, your doctor windows might be able to look for heart problems or suggest lifestyle modifications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

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-hand corner of your heart. This can cause your heart to feel like it skips a beating or has extra beats. PVCs are more frequent among those who suffer from heart issues however, it's not clear what causes them. PVCs are more likely to occur as you age, and may be more frequent during exercising.

A physician should perform an ECG along with an echocardiogram on a patient that suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely conduct an exercise stress test to determine if the additional heartbeats are caused by physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study could be done to look for other reasons for the increased beats.

Most people with PVCs are not affected and can lead a normal life. However, they may increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases, this means that the heart muscle gets weaker and has difficulty pumping blood throughout the body.

Regular exercise and a balanced diet will reduce your chances of developing PVCs. Avoid foods high in fat and sodium, and limit your consumption of caffeine and tobacco. Also, you should try to get enough rest and manage stress. Certain medications can increase your risk of getting PVCs. If you are taking one of these medications it is important to follow your window & door doctor's recommendations regarding eating healthy, exercising and taking your medication.

In studies of patients with Pvc doctor burdens that are excessive (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was found. This could lead to a need for a heart transplant in a few patients.
