How a VC Can Affect Your Heart
Many people experience occasional PVCs with no problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.
The rhythm of your heart is controlled by a group of fibers that are located in the upper right-hand part of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from there to the lower chambers of your heart, or ventricles.
Causes
PVCs happen when the electrical impulse that typically initiates your heartbeat in a region called the sinus node (also called the sinoatrial or SA node) doesn't. The impulse actually begins in the ventricles, causing an irregular heartbeat. These extra beats, called ventricular tachycardia or fibrillation, could feel as if your heart skipped a beat, or it feels like it is fluttering. They can occur infrequently and not cause any symptoms, or they can happen often enough to interfere with your quality of life. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.
In most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health problems. Over time, frequent PVCs can weaken the heart muscle. This is particularly true if the PVCs are triggered by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can lead to heart failure.
PVCs can trigger symptoms such as a feeling of your heart skipping a beat, or fluttering. It is also possible to feel breathless. The fluttering may be more evident when you exercise, or consume certain drinks or foods. PVCs are more prevalent in people with chronic anxiety or stress. Some drugs, like digoxin, amiodarone, and cocaine, can also increase the risk.
If you have occasional PVCs your doctor might suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain foods and beverages, such as alcohol and caffeine. You can also lessen your stress levels by getting enough sleep and exercising.
If you've got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which eliminates the cells that are responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is typically effective in treating PVCs and reducing symptoms, but does not prevent them from becoming recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), a condition that can cause stroke. This is rare, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs, can make your heart appear to flutter or skip one beat. These extra heartbeats are usually harmless, however, you should consult your physician in case you experience frequent episodes or signs like dizziness or weakness.
Normally, electrical signals start in the sinoatrial node, which is in the top right portion of the heart. They travel down to the lower chambers (or ventricles) that pump blood. The ventricles contract to propel blood into your lungs, and then return to the heart to begin the next pumping cycle. But a PVC starts at a different spot and is located in the bundle of fibers, known as the Purkinje fibers, in the left-hand side of the heart.
When PVCs occur and the heart is affected, it may appear to be skipping a beat or pounding. If you've experienced just a few episodes but no other symptoms, the doctor probably won't be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. glass doctor may also recommend wearing a Holter Monitor which tracks the heart's rhythm and count the number of PVCs.
Anyone who has suffered previously from a heart attack or cardiomyopathy, an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and speak to an expert in cardiology about lifestyle changes. These include cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medication to slow the heartbeat, such as a beta blocker.
If you experience frequent PVCs, even if you do not have any other symptoms you should see an expert in cardiology. These extra heartbeats can be a sign of a problem with the structure of your heart or other health conditions and, over time when they are frequent enough, they may weaken the heart muscle. But the majority of people suffering from PVCs don't have any issues. They are interested in knowing if the irregular heartbeats or fluttering is normal.
Diagnosis
PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them frequently might feel faint. Exercise can trigger them, but many athletes who experience them do not have heart or health problems. PVCs can be detected on tests such as an electrocardiogram or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to examine the heart and see how it's working.
A doctor is often able to tell if a patient has PVCs by examining them and taking their medical history. Sometimes it is possible that they only be able to detect PVCs when they examine a patient for another reason, like following an accident or a surgery. Ambulatory ECG monitoring systems can also assist in detecting PVCs and other arrhythmias and they might be used in the event of any suspicion of heart disease.
If your cardiologist determines your heart is structurally healthy, reassurance could be all you need. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, speak to your physician about the medications that could help control the symptoms.
Treatment
If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If you have them often, your doctor may want to look for other heart issues and recommend lifestyle changes or medication. You could also have an operation (called radiofrequency cathode ablation) to get rid of them.
If you suffer from PVCs the electrical signal that causes your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right part of your heart. This can cause your heart to feel like it skips beats or has extra beats. They're more common among people with heart problems, but it's not known what causes them. PVCs may increase in frequency as we age and can occur more frequently during exercising.
A physician should perform an ECG and an echocardiogram on a patient that suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely conduct an exercise stress test in order to determine if the additional heartbeats are caused by physical exercise. To determine whether there are any other causes for the extra beats, a heart catheterization or a cardiac MRI is possible.
Most people who suffer from PVCs don't experience any complications and can lead a normal lifestyle. But they can increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some cases, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout your body.
A regular, healthy diet and regular exercise can reduce the chances of developing PVCs. You should avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. Sleep and stress are equally crucial. Some medicines can also increase the risk of getting PVCs. If you take any of these medicines, it is important that you follow your doctor's advice about eating healthy and exercising as well as taking your medication.
In studies of patients with PVC burdens that are high (more than 20% of heartbeats) the higher rate of arrhythmia-induced myopathy in the heart was observed. Certain people may require a heart transplant.
