How a VC Can Affect Your Heart
PVCs are common and can be experienced by a variety of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.
The heart's rhythm is controlled by a group of nerve fibers situated in the upper right corner of your heart. This is called the sinoatrial node or SA. Electrical signals travel from there to the lower heart chambers, or ventricles.
double glazing doctor are caused by the electrical impulse that normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) is not initiated. The impulse actually starts in the ventricles, which causes a mistimed heartbeat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. It could feel as if the heart skipped a beat or feels fluttering. They can happen infrequently and not cause any symptoms, but they may occur frequently enough to impact your quality of life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medication.
PVCs are generally safe and do not increase your risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially the case if they are caused 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 slower or is fluttering, and you feel breathless. The fluttering could be more noticeable if you exercise, or eat or drink certain beverages or foods. People who suffer from chronic stress or anxiety can have more PVCs, and some medications like amiodarone digoxin, and cocaine may increase the risk of developing them.
If you are experiencing occasional PVCs, your doctor may recommend lifestyle changes and medicines. If they are a regular occurrence, you may have to avoid some drinks and foods like alcohol and caffeine. You can also reduce your stress levels, and make sure you get enough sleep and exercise.
If you have a lot of PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It destroys cells that cause PVCs. Electrophysiologists are the ones who perform this procedure. It is generally effective in treating PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In certain cases it can increase your risk of having atrial fibrillation (AFib) which can lead to a stroke. This is rare however it could be life-threatening.
Signs and symptoms
Premature ventricular contracts, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats are harmless, however you might want to consult your doctor if they are frequent or if you notice symptoms like dizziness, or fatigue.
The normal electrical signals start in the sinoatrial region, which is in the upper right corner of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. The ventricles expand to force blood into the lung. They return to the heart's center to begin the next cycle of pumping. A PVC begins at a different spot that is the Purkinje fibers are located in the left-hand side of the heart.
When PVCs happen and the heart is affected, it may feel like it is beating faster or slower. If you experience only a few episodes, but no other symptoms, your doctor will probably not treat you. If you have a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. They may also suggest wearing a Holter monitor, which will record your heartbeat over time to determine the number of PVCs you have.
Anyone who has suffered previously from a heart attack or have suffered from cardiomyopathy - an illness that affects method by which the heart pumps blood - should take their PVCs very seriously and consult a cardiologist about lifestyle modifications. These include abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.
Even if you don't experience any other signs, you should still get PVCs examined by an expert in cardiology if they occur frequently. These extra heartbeats may signal a problem with the structure of your heart or lungs and if they occur frequently enough, can weaken your heart muscle. Most people with PVCs do not experience any issues. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal.
Diagnosis
PVCs can appear to be fluttering or skip heartbeats, especially when they are frequent or intense. People who experience them frequently may feel faint. They can also happen with training, even though many athletes who get them do not have any issues with their heart or health. PVCs may show up on tests such as an electrocardiogram or a Holter monitor. They use sticky patches with sensors to record electrical impulses coming from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to look at the heart and determine how it's functioning.
A doctor can often tell if a patient has PVCs by looking at them and taking a medical history. Sometimes, however, they may only notice PVCs when examining patients for a different reason, like following an accident or a surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and could be utilized if there's any concern of cardiac disease.
If your cardiologist determines that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are bothersome or cause you to feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help reduce the frequency of PVCs. If the symptoms persist or are extreme, talk with your physician about possible medications that can control these symptoms.
Treatment
If PVCs aren't causing symptoms or occur rarely they aren't usually in need of treatment. If they occur frequently your doctor may want to check for heart problems or suggest lifestyle modifications. You may also undergo a procedure (called radiofrequency cathode ablation) to get rid them.
If you have PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere different than the sinoatrial (SA) node, which is located in the upper right corner of your heart. This could cause it to feel like your heart skips a beat or is beating faster. PVCs are more prevalent among people with heart problems, but it's not known the reason behind them. PVCs can become more frequent as you age, and could be more frequent during exercises.
If a patient is experiencing frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to determine whether the additional beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other causes of the increased beats.
Most people with PVCs don't experience any complications and can lead an ordinary life. They could increase the risk of dangerous heart rhythm disorders particularly if they develop in certain patterns. In certain cases, it means the heart muscle gets weaker and is unable to pump blood throughout your body.
A healthy, regular diet and a lot of exercise can reduce the risk of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Some medicines can also increase the risk of developing PVCs. If you are taking any of these medicines it is crucial that you follow the advice of your doctor regarding healthy eating and exercising as well as taking your medication.
In studies of patients suffering from PVC burdens that are high (more than 20% of total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. This could lead to the need for a heart transplant in some individuals.
