How a VC Can Affect Your HeartPVCs are common and may be experienced by a wide range of people with no cause for concern. If they happen frequently, PVCs may weaken your heart and increase your chance of suffering from heart failure.
double glazing doctors is controlled by a bundle of fibers that are located in the upper right corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from there to the lower heart chambers, or ventricles.
Causes
PVCs are caused when the electrical impulse that typically initiates your heartbeat in a region called the sinus node (also called the sinoatrial or SA node) isn't. The impulse actually starts in the ventricles, causing an untimed heartbeat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or is 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. Your doctor might prescribe medication in the event that they are frequent or cause weakness, dizziness or fatigue.
For the majority of people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health issues. In time, frequent PVCs can weaken the heart muscle. This is particularly when the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.
PVCs can cause symptoms, such as a sensation of your heart skipping an beat, or fluttering. It is also possible to feel breathless. The fluttering can be more evident if you exercise, or eat or drink certain foods or beverages. PVCs are more prevalent for those who suffer from chronic stress or anxiety. Some medications, such as digoxin, amiodarone and cocaine, can increase the risk.
If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medication. If you are prone to frequent PVCs, your physician may suggest that you stay away from certain foods and drinks such as caffeine and alcohol. You can also take steps to lessen your stress and get plenty of sleep and exercise.
If you're experiencing many PVCs the doctor might suggest a medical procedure called radiofrequency catheter ablation, which destroys cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. The treatment is generally effective in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In certain cases, it can increase your risk of atrial fibrillation (AFib), which can result in stroke. This isn't common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions, also known as PVCs, can make your heart appear to skip or flutter a beat. These heartbeats can be harmless, but it is important to talk to your doctor when you experience frequent episodes or other symptoms such as dizziness or weakness.
The electrical signals typically begin in the sinoatrial node, located in the upper right portion of the heart. These signals descend to the lower chambers (or ventricles) that pump blood. The ventricles then contract to force blood into the lung. They return to the center to start the next cycle of pumping. However, a PVC starts in a different place, from the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.
When PVCs happen they can make the heart feel as if it's racing or pounding. If you experience a few episodes and no other symptoms, the doctor will probably not treat you. If you have many PVCs the doctor may recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. They might also recommend wearing a Holter monitor that will track your heart rhythm over time, allowing you to see the number of PVCs you have.
If you've had a previous heart attack or have suffered from cardiomyopathy - an illness that affects the way the heart pumps blood - should take their PVCs very seriously and consult an expert in cardiology about lifestyle modifications. This includes abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.
Even if there aren't any other symptoms however, you should have PVCs checked by an expert in cardiology if they occur frequently. These irregular heartbeats could indicate a problem in the structure of your heart or lungs and if they occur often enough, they can weaken your heart muscle. Most people who suffer from PVCs do not experience any problems. They want to know if the fluttering heartbeats or skipping heartbeats is normal.
Diagnosis
PVCs can be akin to heartbeats that flutter, especially if they are frequent and intense. People who experience a lot of them may feel they're about to faint. They can also occur with training, even though many athletes who suffer from them don't have issues with their health or heart. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors that record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to study the heart and observe how it's functioning.
A doctor may be able to tell whether someone has PVCs from a patient's history and physical exam. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason, like following an accident or a surgery. Ambulatory ECG monitoring systems can also aid in detecting PVCs and other arrhythmias, and they might be used in the event of any suspicion of cardiac disease.
If your cardiologist determines that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine and other over the counter decongestants, and reducing stress may aid. Getting regular exercise, staying at a healthy weight, and drinking enough water can also reduce your episodes of PVCs. If your symptoms persist or are severe, speak to your doctor about medications that can control these symptoms.
Treatment
If PVCs don't cause symptoms or happen rarely they aren't usually in need of treatment. If they are frequent, your doctor might be able to look for heart problems or suggest lifestyle adjustments. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid them.
If you suffer from PVCs, the electrical signal that triggers your heartbeat starts somewhere outside of the sinoatrial node (SA node) located in the upper right corner of your heart. This can make it feel like your heart skips a beat or is beating faster. PVCs are more prevalent among people who suffer from heart issues, but it's not known the reason behind them. PVCs may increase in frequency as you age, and could be more frequent during exercising.
If a patient has frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They should also conduct an exercise stress test to see whether the extra beats are a result of physical exercise. To find out if there are other causes for the extra beatings, a heart catheterization or an MRI is possible.
Most people with PVCs do not have any issues and can lead a normal life. However, they can increase your risk of having dangerous heart rhythm issues particularly if you have certain patterns of them. In some instances, this means that your heart muscle gets weaker and is having difficulty pumping blood throughout your body.
A regular, healthy diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of tobacco and caffeine. Also, you should try to get enough rest and manage stress. Certain medications can increase your risk of PVCs. If you are taking one of these medications, it's important to follow the doctor's advice about eating well, exercising and taking your medication.
Studies of patients who had a high burden of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in a few patients.
