How a VC Can Affect Your Heart
A lot of people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The rhythm of your heart is controlled by a bundle of fibers located in the upper right part of your heart. This is called the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles or lower chambers of your heart.
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 and causes an untimed heartbeat. These extra beats are also known as ventricular tachycardia and ventricular fibrillation. It may feel like the heart skipped a beating or feels like it is fluttering. They can occur infrequently and have no symptoms or they can happen often enough to affect your quality of life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor may treat them with medication.
PVCs are generally harmless and don't increase your risk of developing heart disease. Frequent PVCs however, may weaken the heart muscle over time. This is especially true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.
The signs of PVCs include feeling like your heart beats slower or flutters, and you may feel exhausted. The fluttering may be more noticeable when you exercise or consume certain drinks or food items. People who suffer from chronic anxiety or stress can have more PVCs and certain medications like amiodarone digoxin and cocaine can increase the risk of developing them.
If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medications. If they are a frequent occurrence, you may need to avoid some foods and beverages, such as caffeine and alcohol. You can also reduce your stress levels, and take advantage of plenty of rest and exercise.
If you have many PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which eliminates the cells responsible for them. Electrophysiologists are the ones who perform this procedure. It is typically successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from recurring in the future. In certain cases, it can increase your risk of atrial fibrillation (AFib) which could result in stroke. It's not common, but it can 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, however you might need to see your doctor if they are frequent or if you notice symptoms like dizziness, or fatigue.
The electrical signals normally begin in the sinoatrial, located in the upper right corner of the heart. They then move to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles then contract to force blood into the lungs. They return to the center to begin the next cycle of pumping. A Pvc Doctor begins in a different place, the Purkinje fibres bundle in the left side of the heart.
When PVCs occur, they make the heart beat faster or feel as if it skipped the beat. If you've experienced a few episodes and no other symptoms, your doctor probably won't be able to treat you. But if you have a number of PVCs, the doctor may suggest an electrocardiogram, or ECG to determine the heart's rate over a 24-hour period. The doctor may also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.
Anyone who has suffered an earlier heart attack or cardiomyopathy, an illness that affects the way the heart pumps blood - must take their PVCs seriously and speak to a cardiologist about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.
If you have frequent PVCs even if don't have any other symptoms, you should consult a cardiologist. These extra heartbeats may be a sign of a problem with the structure of your heart or lungs, and if they happen often enough, it could weaken the heart muscle. But the majority of people with PVCs don't have any issues. They would like to know if irregular heartbeats or fluttering is normal.
Diagnosis
PVCs may feel like heartbeats that are fluttering especially if they are frequent and intense. People who experience them often may feel faint. Exercise can trigger them, but most athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors to record electrical signals from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.
Most of the time, a doctor will be able to identify if the patient has PVCs from a patient's history and physical examination. However, sometimes they will only be able to detect them when they examine the patient for different reasons, like following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs and other arrhythmias. They may be used to identify cardiac problems in the event of any concern.
If your cardiologist concludes that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are causing you discomfort or cause you to be anxious, avoiding alcohol, caffeine, and over the counter decongestants, and the reduction of stress could aid. Getting regular exercise, staying at a healthy weight and drinking enough fluids can decrease the likelihood of PVCs. If your symptoms are persistent or extreme, consult your upvc door doctor about medications that could help control the symptoms.
Treatment
If PVCs aren't common or don't cause symptoms, they do not usually need treatment. If they happen frequently, your doctor might be able to look for heart conditions or recommend lifestyle changes. You might also get an intervention to get rid of them (called radiofrequency catheter ablation).
If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. It can feel like your heart skips beats or has extra beats. PVCs are more prevalent among people with heart problems however, it's not clear what causes them. PVCs can increase in frequency with age and might happen more frequently during exercises.
A doctor should perform an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to rule out structural heart diseases. They should also conduct an exercise stress test to determine if the extra beats are a result of physical exercise. To determine whether there are any other causes for the increased beats, a heart catheterization or a cardiac MRI is possible.
The majority of people with PVCs are not affected and live the normal life. However, they may increase the risk of developing dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In certain cases, it means the heart muscle gets weaker and is having difficulty pumping blood through your body.
Regular exercise and a healthy diet can lower your chances of developing PVCs. Avoid foods that are high in sodium and fat, and you should also reduce your intake of caffeine and tobacco. Sleep and stress are also crucial. Certain medicines can also increase the risk of getting PVCs. So if you take one of these drugs it's crucial to follow the doctor's advice regarding eating healthy, exercising and taking your medication.
Studies of patients suffering from an excessive amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
