How a VC Can Affect Your Heart
PVCs are common and can be experienced by a variety of people with no cause for concern. If they occur often, PVCs may weaken your heart and increase your chance of suffering from heart failure.
The rhythm of your heart is usually controlled by a group of fibers that are located in the upper right part of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel to ventricles or lower chambers of your heart.
Causes
PVCs happen by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) is not initiated. The impulse actually begins in the ventricles and causes a mistimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat or feels like it's fluttering. They can occur infrequently and have no symptoms or they may occur frequently enough to interfere with your quality of life. If they are very frequent or cause dizziness, weakness or fatigue, your doctor may treat them with medicine.
For most people, PVCs are harmless and do not increase the risk of heart disease or other health issues. Regular PVCs however, could weaken the heart muscle over time. This is especially the case if they are caused by a heart-related condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.
PVCs can cause symptoms such as a feeling of your heart skipping a beat, or fluttering. You may also feel exhausted. The fluttering may be more noticeable when you exercise or consume certain foods or drinks. PVCs are more prevalent in people with chronic anxiety or stress. Certain drugs, like digoxin, amiodarone window and door doctor cocaine, can also increase the risk.
If you experience occasional PVCs Your doctor may suggest lifestyle changes and medications. If you are prone to frequent PVCs, your doctor might recommend avoiding certain foods and drinks such as alcohol and caffeine. You can also take steps to lessen your stress, and take advantage of plenty of rest and exercise.
If you've got a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. This procedure is performed by a specialist called an electrophysiologist. 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 the risk of developing atrial fibrillation (AFib) which is which can result in stroke. This isn't common however it could be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats are harmless, however you might want to consult your doctor if they are frequent or if you are experiencing symptoms like dizziness or fatigue.
The electrical signals normally begin in the sinoatrial region, which is in the upper right part of the heart. They then move to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles contract to pump blood into the lung. They return to the heart's center to start the next cycle of pumping. A Pvc doctor starts in a different location in the Purkinje fibers are located in the left side of the heart.
When PVCs occur, they cause the heart pound or feel like it skipped the beat. If you only have just a few episodes and no other symptoms are present your cardiologist may not prescribe treatment. However, if you have large number of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG, to measure your heartbeat over the course of 24 hours. They may also recommend wearing a Holter monitor that will track the heart's rhythm over time to determine how many PVCs you have.
People who have suffered an earlier heart attack or have suffered from cardiomyopathy - an illness that affects heart's blood flow - must take their PVCs seriously and speak to an expert in cardiology about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist might prescribe medications to slow heartbeat, for example, a beta blocker.
If you have frequent PVCs, even if you do not have any other signs, you should see an expert in cardiology. These extra heartbeats may indicate a problem in 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 do not experience any issues. They are interested in knowing if the irregular heartbeats or fluttering is normal.
Diagnosis
PVCs may appear to be fluttering or skip heartbeats, especially when they're intense or frequent. People who experience them frequently may feel faint. They can also occur with exercising, but most athletes who experience them don't have issues with their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to examine the heart and determine how it's functioning.
Most of the time, a doctor will be able to determine if someone has PVCs from a history and physical exam. Sometimes it is possible that they only be able to detect PVCs when they examine patients for a different reason, like following an accident or surgical procedure. 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 concern.
If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. However, 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 aid. Regular exercise, maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medication that could help control these symptoms.
Treatment
If PVCs are rare or don't cause symptoms, they do not usually need treatment. If they occur frequently, your doctor might need to examine for heart problems or suggest lifestyle changes. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).
If you have PVCs The electrical signal that causes your heartbeat is generated from a place different than the sinoatrial nerve (SA node) in the top right side of your heart. This could cause your heart to feel as if it skips a beating or has extra beats. It's not known what causes these, but they're more frequent in those with other heart conditions. PVCs can become more frequent as you age, and could be more frequent during exercise.
A physician should perform an ECG along with an echocardiogram on a patient that has frequent and painful PVCs to determine if there are structural heart problems. The windows doctor will also conduct an exercise stress test to determine if the increased heartbeats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other causes for the extra beats.
The majority of people with PVCs do not have any issues and can live an ordinary life. But they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some cases, this means that the heart muscle gets weaker and is unable to pump blood throughout your body.
A regular, healthy diet and a lot of exercise can help reduce your risk of developing PVCs. You should avoid foods that are high in fat and sodium as well as restrict your intake of tobacco and caffeine. It is also important to get enough sleep and manage stress. Certain medicines can also increase your risk for PVCs. If you take any of these medicines it is crucial to follow the window doctor advice of your doctor about eating healthy, exercising, and taking your medication.
In studies of patients suffering from PVC burdens that are high (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. Some people may need an organ transplant.
