How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by many people without causing any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.
The rhythm of your heart is controlled by a bundle of fibers located in the upper right corner of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals are transmitted from there to the lower heart chambers or ventricles.
Causes
PVCs are caused when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles and causes a mistimed heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat, or it feels like it is like it's fluttering. They can occur infrequently and cause no symptoms, or they can occur frequently enough to affect your daily life. Your doctor may prescribe medicine when they occur frequently or cause weakness, dizziness or fatigue.
PVCs are generally safe and do not increase your risk of heart disease. A lot of PVCs however, could weaken your heart muscle over time. This is especially relevant if the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause 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. PVCs are more prevalent in those suffering from chronic stress or anxiety. Certain drugs, like digoxin, amiodarone or cocaine, can also increase the risk.
If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medication. If they're a frequent occurrence, you may need to avoid some drinks and foods, such as alcohol and caffeine. You can also lower stress by taking enough rest and working out.
If you have many PVCs Your doctor might recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. window doctors is carried out by a specialist known as an electrophysiologist. The treatment is usually successful in treating PVCs and reducing symptoms, but it does not stop them from becoming recurring in the future. In certain instances, it can increase the 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 contracts PVCs, also known as PVCs, can cause your heart to skip or be fluttering. These extra heartbeats are usually harmless, but it is important to talk to your doctor in case you experience frequent episodes or other symptoms such as dizziness or weakness.
The electrical signals normally begin in the sinoatrial area, which is located in the upper right-hand corner of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles contract to pump blood into the lungs. They return to the heart's center to start the next cycle of pumping. A PVC begins at a different spot that is the Purkinje fibres bundle in the left side of the heart.
When PVCs occur, they cause the heart beat or feel as if it skipped a beat. If you've experienced only a few episodes, but no other symptoms, your doctor probably won't be able to treat you. If you have a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat over the course of 24 hours. He or she might also recommend wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.
If you've had a prior heart attack or suffer from cardiomyopathy -an illness that alters the way the heart pumps blood- should be aware of their PVCs and speak with a cardiologist about lifestyle changes. This includes avoiding caffeine, alcohol and smoking, managing stress and anxiety and getting enough sleep. A cardiologist may prescribe medications to slow the heartbeat, such as beta blockers.
Even if you don't have any other indications it is still recommended to have PVCs examined by an cardiologist if they occur frequently. These heartbeats that are irregular can be a sign of an issue with the structure of your heart or other health issues, and over time, if they occur often enough, they could weaken the heart muscle. However, most people with PVCs do not experience any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.
Diagnosis
PVCs may appear to be fluttering or skip heartbeats, particularly when they're intense or frequent. People who experience them regularly might feel faint. They can also occur with training, even though many athletes who suffer from them do not have any issues with their health or heart. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to study the heart and determine how it's functioning.
Most of the time, a doctor will be able to identify if the patient is suffering from PVCs from a patient's history and physical examination. Sometimes however, they might only notice PVCs when examining the patient for another reason, like following an accident or surgical procedure. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and could be utilized in the event of any suspicion of cardiac disease.
If your cardiologist determines your heart is structurally healthy, reassurance might be all you need. However, if your symptoms are bothersome or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight, and drinking enough fluids can aid in reducing the frequency of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medications that could be able to manage these symptoms.
Treatment
If PVCs are rare or do not cause symptoms, they rarely require treatment. If they occur frequently your doctor may need to examine for heart issues or suggest lifestyle modifications. You could also have a procedure (called radiofrequency cathode ablation) to eliminate of them.
If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located different than the sinoatrial (SA) node that is located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or has a few extra beats. It's not known what causes these symptoms, but they're frequent in those with other heart problems. PVCs can increase in frequency as we age and can occur more frequently during exercising.
If a patient is experiencing frequent and painful PVCs the doctor should conduct an ECG and an echocardiogram to rule out structural heart disease. They may also perform an exercise stress test to determine whether the additional beats are a result of physical activity. To determine whether there are other reasons for the increased beats the heart catheterization or an MRI is possible.
Most people with PVCs are not affected and can lead a normal life. They could increase your risk for dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, that means that the heart muscle becomes weaker and is unable to pump blood through your body.
Regular exercise and a balanced diet can lower the risk of developing PVCs. Avoid foods high in fat and sodium and limit your intake of tobacco and caffeine. Sleep and stress are equally crucial. Certain medicines can also increase the risk of getting PVCs. If you take any of these medicines it is essential to follow the advice of your doctor regarding eating a healthy diet and exercising as well as taking your medication.
Studies of patients who had a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in a few people.
