How a VC Can Affect Your Heart
Many people have occasional PVCs with no problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.
A bundle of fibers in the upper right part of your heart (the sinoatrial node, also known as SA) usually controls your heart's rhythm. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.
Causes
PVCs are caused when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. The impulse actually begins in the ventricles, causing a mistimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It may feel like the heart skipped a beat or feels like it is fluttering. They can occur rarely and not cause any symptoms, but they can be frequent enough to impact your quality of life. upvc doctor may prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.
In most people, PVCs are harmless and don't increase your risk of heart disease or other health problems. A lot of PVCs however, could weaken the heart muscle over time. This is especially relevant if they are triggered by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.
The symptoms of PVCs include feeling like your heart beats faster or is fluttering, and you feel exhausted. The fluttering could be more noticeable when you exercise, or consume certain foods or beverages. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone, and cocaine, can also increase the risk.
If you have occasional PVCs Your doctor may recommend lifestyle changes and medicines. If you are prone to frequent PVCs, your physician may recommend that you avoid certain foods and drinks, such as alcohol and caffeine. You can also reduce your stress levels by taking enough rest and working out.
If you've got a lot of PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. It destroys the cells that cause them. The procedure is carried out by a specialist known as an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which can result in stroke. It is not common however it could be life-threatening.
Signs and symptoms
Premature ventricular contracts or PVCs may cause your heart to skip or flutter. These heartbeats that are not normal can be harmless, but you may be advised to consult your physician if they are frequent or if you experience symptoms like dizziness, or fatigue.
Normally, electrical signals start at the sinoatrial junction, which is in the top right-hand side of the heart, and travel down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to propel blood into your lungs, and return to the heart to begin the next cycle of pumping. A PVC starts in a different place that is the Purkinje fibres bundle in the left-hand side of the heart.
When PVCs occur, they can make the heart beat faster or feel as if it skipped one beat. If you have only a few episodes, and no other symptoms are present your cardiologist may not 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 for a period of 24 hours. He or she might also recommend wearing a Holter monitor that will track your heart rhythm over time, allowing you to see how many PVCs you have.
If you've had previously from a heart attack or cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. This includes cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe medications to slow the heartbeat, such as beta blockers.
Even if you don't have any other indications however, you should have PVCs examined by an expert in cardiology if they occur frequently. These heartbeats that are irregular could indicate a problem in the structure of your lungs or heart, and if they occur often enough, can weaken the heart muscle. But most people with PVCs don't have any issues. They simply want to be aware that the fluttering and racing heartbeats aren't normal.
Diagnosis
PVCs may appear to be fluttering or skip heartbeats, particularly when they are frequent or intense. People who experience them regularly may feel weak. They can also occur during exercise, though many athletes who experience them do not have any issues with their heart or health. PVCs can be detected in tests like an electrocardiogram or a Holter monitor. They use sticky patches with sensors on them to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram for examining the heart.
Most of the time, a doctor will be able to tell whether the patient has PVCs through a medical history and physical examination. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason such as following an accident or surgery. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias, and could be utilized when there is a concern of cardiac disease.
If your cardiologist concludes that your heart is structurally normal, reassurance will be the only remedy required. However, if your symptoms are troubling or cause you to feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress can aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If your symptoms persist or severe, talk to your physician about the medications that could help manage the symptoms.
Treatment
If PVCs aren't common or don't cause symptoms, they don't usually require treatment. If they occur frequently your doctor may need to examine for heart issues or suggest lifestyle modifications. You may also undergo an operation (called radiofrequency cathode ablation) to eliminate them.
If you have PVCs The electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right part of your heart. This could cause your heart to feel like it skips beats or has extra beats. It's not clear what causes these, but they're more common in people with other heart conditions. PVCs are more frequent with age and might happen more frequently during exercises.
If a patient experiences frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out structural heart disease. They will probably also do an exercise stress test to see whether the additional beats are caused by physical exercise. To determine whether there are other reasons for the increased beats, a heart catheterization or cardiac MRI can be performed.
Most people who suffer from PVCs don't experience any issues and can live a normal lifestyle. However, they may increase the risk of developing dangerous heart rhythm issues, especially if you have certain patterns of them. In some instances, this means that your heart muscle gets weaker and is having difficulty pumping blood through your body.
Regular exercise and a healthy diet can lower the chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your intake of caffeine and tobacco. Also, you should try to get enough sleep and manage stress. Certain medicines can also increase your risk of PVCs. If you take any of these medications it is crucial that you follow your doctor's recommendations regarding healthy eating and exercising as well as taking your medication.
In studies of patients suffering from PVC burdens that are excessive (more than 20% of total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. Some people may need an organ transplant.
