How a VC Can Affect Your Heart
Many people have occasional PVCs and have no issues. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.
The rhythm of your heart is controlled by a bundle of nerve fibers situated in the upper right part of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from this node to the lower heart chambers, or ventricles.
Causes
PVCs happen when the electrical impulse that usually begins your heartbeat at a point known as the sinus node (also called the sinoatrial or SA node) does not. Instead, the impulse begins in a different part of your heart, the ventricles, and causes a wrongly timed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They may occur infrequently and not cause any symptoms, but they could occur frequently enough to affect your standard of living. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor may treat them with medicine.
In most people, PVCs are harmless and don't increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.
PVCs can cause symptoms like a feeling of your heart skipping an beat, or fluttering. You may also feel breathless. The fluttering may be more evident when you exercise or consume certain beverages or foods. PVCs are more common for those who suffer from chronic stress or anxiety. Certain medications, like digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.
If you have occasional PVCs your double glazing doctor may suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain drinks and foods, such as caffeine and alcohol. You can also take steps to lessen your stress and take advantage of plenty of rest and exercise.
If you have lots of PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation, which destroys the cells that are responsible for PVCs. This is done by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs which reduce symptoms, but it does not stop them from becoming recurring in the future. In some instances it may increase the risk of developing atrial fibrillation (AFib) which can cause stroke. This is rare but can be life-threatening.
Signs and symptoms
Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or be fluttering. These extra heartbeats are harmless, but you might need to see your doctor when they occur frequently or if you notice symptoms like dizziness, or fatigue.
The electrical signals normally begin in the sinoatrial area, which is located in the upper right corner of the heart. They then move to the lower chambers, also known as ventricles, where blood pumps are located. Then, the ventricles expand to push blood into your lungs and then return to your heart to begin the next pumping cycle. But a PVC starts at a different spot that is separate from the bundle of fibers known as the Purkinje fibers, in the lower left part of the heart.
When PVCs happen, the heart may feel as if it's racing or pounding. If you only have a few episodes, and there are no other symptoms, your cardiologist will probably not prescribe treatment. But if you have a lot of PVCs, the doctor may recommend an electrocardiogram, or ECG, to measure your heart rate over a 24-hour period. They may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.
If you've suffered a heart attack in the past or suffer from cardiomyopathy -which affects how the heart pumps blood - should take their PVCs seriously and speak with a cardiologist about changes to their lifestyle. This includes cutting down on caffeine, alcohol and smoking, managing anxiety and stress, and getting enough rest. A cardiologist might also prescribe medication to slow the heartbeat such as a beta blocker.
If you are experiencing frequent PVCs even if do not have other symptoms, you should consult a cardiologist. These irregular heartbeats could point to problems with the structure of your heart or other health conditions and, over time, when they are frequent enough, they can weaken the heart muscle. The majority of people with PVCs do not have any issues. They are interested in knowing if the fluttering heartbeats or skipping heartbeats is normal.
Diagnosis
PVCs can be akin to heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them often may feel weak. They can also occur with training, even though many athletes who experience them don't have issues with their health or heart. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to look at the heart and determine how it's functioning.
A doctor is often able to tell the presence of PVCs by examining them and taking their medical history. Sometimes it is possible that they only be able to detect PVCs when they examine patients for a different reason such as following an accident or surgical procedure. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias and can be used if there's any concern of cardiac disease.
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 feel anxious, staying away from alcohol, caffeine, and over the prescription decongestants, as well as reducing stress may help. Engaging in regular exercise, keeping at a healthy weight and drinking enough water can also reduce your episodes of PVCs. If your symptoms are persistent or extreme, consult your upvc door doctor about medications that could help manage these symptoms.
Treatment
If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If they happen frequently your window doctor may be able to look for heart problems or suggest lifestyle changes. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.
If you suffer from PVCs, the electrical signal that triggers your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right part of your heart. This can make it feel like your heart skips beats or is beating faster. It's not clear what causes these symptoms, but they're common in people who have other heart issues. PVCs may increase in frequency as we age and can occur more often during exercising.
A physician should perform an ECG as well as an echocardiogram on a patient who has frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely perform an exercise stress test to determine if the increased heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other causes of the window doctors extra beats.
Most people who suffer from PVCs do not suffer from any issues and can live an ordinary life. They can increase the risk of 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 your body.
A healthy, regular diet and regular exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat, and you should also reduce your intake of 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 medicines it is important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication.
In studies of patients with pvc Doctor burdens that are high (more than 20% of the total heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. This could lead to a need for a heart transplant in certain patients.
