How a VC Can Affect Your Heart
Many people experience occasional PVCs and have no issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
A bundle of fibers in the upper right part of your heart (the sinoatrial or SA node) typically regulates your heart rhythm. Electrical signals are transmitted to the ventricles or lower chambers of your heart.
Causes
PVCs are caused when the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles, which causes a mistimed heartbeat. These extra beats, bulletproof window repair – https://Sloth-robinson-2.blogbright.net, known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or Historic window repair feels like it’s fluttering. They can happen infrequently and not cause any symptoms, or Porthole Window Repair they can occur frequently enough to affect your quality of life. Your doctor may prescribe medicine when they occur frequently or cause dizziness, weakness or fatigue.
For most people, PVCs are harmless and don’t increase your risk of developing heart disease or other health problems. Over time, repeated PVCs can weaken the heart muscle. This is particularly the case if they are caused by a heart-related condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.
The symptoms of PVCs include feeling like your heart skips a beat or it flutters. You may feel exhausted. The fluttering can be more noticeable when you exercise or consume certain foods or drinks. PVCs are more prevalent in those suffering from chronic anxiety or stress. Certain drugs, like digoxin, amiodarone, and cocaine, can increase the risk of developing PVCs.
If you have occasional PVCs your doctor might suggest lifestyle changes and medications. If they’re a frequent occurrence, you may need to avoid some drinks and foods like alcohol and caffeine. You can also take steps to lessen your stress, and make sure you get enough sleep and exercise.
If you’ve got a lot of PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells that are responsible for them. The procedure is carried out by a specialist called an electrophysiologist. It is typically successful in treating the PVCs and reducing symptoms however, it doesn’t prevent them from recurring in the future. In some cases, it can increase your risk of having atrial fibrillation (AFib) which could result in a stroke. This isn’t common but it could be life-threatening.
Signs and symptoms
Premature ventricular contractures or PVCs may cause your heart to skip or to flutter. These heartbeats can be harmless, but you should consult your physician if you have frequent episodes or other symptoms such as dizziness or weakness.
Normally, electrical signals begin in the sinoatrial node, located in the top right-hand side of the heart. They move down to the lower chambers (or ventricles) that pump blood. The ventricles contract to push the blood into the lungs. They return to the heart’s center to begin the next cycle of pumping. A PVC starts at a different spot, the Purkinje fibers are located in the left side of the heart.
When PVCs happen, the heart may feel like it is skipping a beat or pounding. If you experience only a few episodes, and there are no other symptoms your cardiologist may not treat you. If you have a lot of PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. He or she may also recommend wearing a Holter monitor that records the heart’s rhythm over time to determine the number of PVCs you have.
Anyone who has suffered a previous heart attack or cardiomyopathy – an illness that affects the heart’s blood flow – should take their PVCs very seriously and speak to a cardiologist about lifestyle changes. These include avoiding caffeine, alcohol and smoking, managing stress and anxiety and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.
Even if you don’t experience any other symptoms, you should still get PVCs checked by an expert in cardiology if they occur frequently. These extra heartbeats can point to a problem with the structure of your heart or other health issues and, over time, if they occur often enough, they could weaken the heart muscle. But the majority of people suffering from PVCs do not experience any issues. They just want to be aware that the fluttering and racing heartbeats aren’t normal.
Diagnosis
PVCs can be akin to heartbeats that are fluttering, especially if they are frequent and intense. People who experience them frequently might feel faint. Exercise can cause PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health problems. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors that record electrical signals from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to examine the heart and see how it’s working.
A doctor may be able to determine if someone is suffering from PVCs from a patient’s history and physical examination. Sometimes it is possible that they only notice PVCs when examining the patient for another reason, such as after an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They may be used to detect heart disease if there is any concern.
If your cardiologist concludes that your heart’s structure is normal, reassurance will be the only treatment needed. If your symptoms are troubling, or cause you to feel anxious, staying away from alcohol, caffeine, and over the counter decongestants, and decreasing stress can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms persist or severe, speak to your physician about the medications that could be able to reduce these symptoms.
Treatment
If PVCs don’t cause symptoms or occur rarely they aren’t usually in need of treatment. If you have them often and frequently, your doctor might want to examine for other heart issues and recommend lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to get rid of them.
When you have PVCs the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial nerve (SA node) located in the upper right corner of your heart. This can cause your heart to feel like it skips beats or has additional beats. It’s not known what causes them, but they’re more common in people with other heart issues. PVCs are more frequent as we age and can occur more frequently during exercising.
A doctor should conduct an ECG along with an echocardiogram on a patient that has frequent and painful PVCs to rule out structural heart diseases. They may also perform an exercise stress test to see if the extra beats are a result of physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be conducted to determine other causes of the additional beats.
Most people with PVCs do not experience any complications and can lead an ordinary life. They may increase the risk of dangerous heart rhythm disorders particularly if they develop in certain patterns. In certain cases, it means that your heart muscle gets weaker and is having difficulty pumping blood through your body.
A regular, healthy diet and plenty of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium, and limit your consumption of caffeine and tobacco. Sleep and stress are also important. Certain medicines can also increase the risk of getting PVCs. If you are taking one of these medications it is important to follow your doctor’s recommendations about a healthy diet, exercise and taking your medication.
Studies of patients who had a high burden of PVCs (that’s more than 20 percent of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. Certain people may require a heart transplant.
