15 Unexpected Facts About Pvc Doctor You've Never Seen
How a VC Can Affect Your Heart
PVCs are common and can be experienced by many people without causing any problems. If they are frequent, 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 the 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 known as the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely without causing any symptoms, but they may be frequent enough to affect your standard of life. Your doctor may prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.
For most people, PVCs are harmless and do not increase the risk of heart disease or other health problems. Frequent PVCs however, may weaken the heart muscle over time. This is especially the case if they are caused by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.
PVCs can cause symptoms, such as a sensation of your heart beating a beat, or the feeling of your heart fluttering. You may also feel breathless. The fluttering may be more apparent when you exercise or consume certain foods or drinks. People with chronic anxiety or stress can have more PVCs and certain drugs like amiodarone digoxin, and cocaine may increase the likelihood of developing them.
If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If you experience frequent PVCs, your doctor might suggest that you stay away from certain foods and drinks, like caffeine and alcohol. You can also lower stress by taking enough rest and exercising.
If you have a lot of PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. Electrophysiologists are the ones who execute this procedure. The treatment is typically successful in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib), which can cause a stroke. It is not common, but it can be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, can make your heart seem to flutter or skip the beat. These heartbeats that are not normal can be harmless, however you might need to see your doctor if they are frequent or if you experience symptoms such as dizziness or fatigue.
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, where blood pumps are located. The ventricles expand to pump blood into the lungs. They then return to the center to begin the next cycle of pumping. A PVC starts in a different location in the Purkinje fibres bundle at the left-hand side of the heart.
When PVCs occur, they make the heart beat or feel as if it skipped a beat. If you only have a few episodes, and there are no other symptoms your cardiologist may not prescribe treatment. If you've got a large number of PVCs the doctor may recommend an electrocardiogram, or ECG, to measure your heart rate over a 24-hour period. The doctor might also recommend wearing a Holter monitor that will track the heart's rhythm over time to see the number of PVCs you have.
Anyone who has had a previous heart attack or suffer from cardiomyopathy -which affects the way that the heart pumps blood -and should take their PVCs seriously and talk to an expert in cardiology about lifestyle changes. These include the avoidance of alcohol, caffeine, and smoking, managing anxiety and stress and getting enough rest. A cardiologist might prescribe medication to slow heartbeat, for example, a beta blocker.
If you have frequent PVCs, even if you do not have other signs, you should see a cardiologist. These extra heartbeats can indicate an issue with the structure of your heart or to other health conditions and, over time when they are frequent enough, they may weaken the heart muscle. But most people suffering from PVCs don't have any issues. They want to know if the fluttering heartbeats or skipping heartbeats is normal.
Diagnosis
PVCs may be felt as fluttering or skipped heartbeats, especially if they're intense or frequent. People who experience them often may feel faint. They can also occur with exercise, though many athletes who suffer from them do not have any issues in their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.
A doctor will usually be able to determine whether a patient has PVCs by looking at them and taking a medical history. Sometimes, however, they may only be able to detect PVCs when they examine a patient for another reason, such as after an accident or a surgery. window doctor monitoring systems can help detect PVCs and other arrhythmias, and can be used in the event of any suspicion of heart disease.
If your cardiologist concludes that your heart is structurally healthy, reassurance might be all you need. However, if your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine and other decongestants as well as reducing stress levels can aid. Getting regular exercise, staying at a healthy weight and drinking enough water can also help reduce the frequency of PVCs. If the symptoms persist or are extreme, talk to your doctor about medication options to treat these symptoms.
Treatment
If PVCs do not cause any symptoms or occur rarely, they usually don't need treatment. If you are frequently affected and frequently, your doctor might want to check for other heart conditions and suggest lifestyle changes or medicine. You could also have a procedure (called radiofrequency cathode ablation) to get rid them.
If you have PVCs, the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial nerve (SA node) in the top right corner of your heart. This could cause your heart to feel like it skips a beating or has additional beats. They're more common among people suffering from heart disease however it's unclear what causes them. PVCs are more likely to occur as you age, and they might occur more frequently during exercising.
A physician should perform an ECG as well as an echocardiogram for a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor may also conduct an exercise stress test to determine if the extra heartbeats are related to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be performed to find other reasons for the additional beats.
Most people who suffer from PVCs do not experience any problems and can enjoy a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some instances, this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.
A regular, healthy diet and plenty of exercise can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of caffeine and tobacco. Sleep and stress are equally crucial. Certain medications can increase your risk of PVCs. If you take any of these medications it is crucial that you follow the advice of your doctor regarding eating a healthy diet exercising, as well as taking your medication.
Studies of patients suffering from a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher risk of arrhythmia-induced cardiomyopathy. Some people may need an organ transplant.
