Pvc Doctor 101: Your Ultimate Guide For Beginners
How a VC Can Affect Your Heart
A lot of people experience occasional PVCs with no problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.
A bundle of fibers in the top right portion of your heart (the sinoatrial or SA node) typically controls the heart's rhythm. Electrical signals travel from there to the lower chambers of your heart or ventricles.
Causes
PVCs are caused when the electrical impulse that normally starts your heartbeat in a part known as the sinus node (also called the sinoatrial or SA node) doesn't. Instead, the impulse begins in a different area of your heart--the ventricles--and causes a mistimed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat or feels fluttering. They can happen infrequently and have no symptoms or they may occur frequently enough to affect your daily life. If they are very frequent or cause dizziness, weakness or fatigue, your doctor might treat them with medication.
For most people, PVCs are harmless and don't increase your risk of heart disease or other health issues. In time, frequent PVCs can weaken the heart muscle. This is particularly the case if they are caused by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.
PVCs can cause symptoms like a feeling of your heart racing one beat, or even the feeling of your heart fluttering. You might also feel exhausted. The fluttering can be more evident when you exercise or have certain drinks or foods. People who experience chronic anxiety or stress may have more PVCs, and some drugs like amiodarone digoxin, and cocaine can increase the chance of developing them.
If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If you experience frequent PVCs, your doctor may suggest that you stay away from certain drinks and foods, such as alcohol and caffeine. You can also take steps to reduce your stress, and get plenty of sleep and exercise.
If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. Electrophysiologists are the ones who carry out this procedure. The treatment is usually effective in treating PVCs and reducing symptoms, but does not prevent them from returning in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib) which is an illness that can lead to stroke. It is not common but it could be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs, may make your heart appear to flutter or skip a beat. These heartbeats can be harmless, but you should talk to your doctor in case you experience frequent episodes or other symptoms such as dizziness or weakness.
Normaly, electrical signals begin in the sinoatrial region, which is in the upper right part of the heart. They then travel to the lower chambers, or ventricles, that pump blood. The ventricles expand to push the blood into the lung. They return to the heart's center to start the next cycle of pumping. A PVC begins at a different spot, the Purkinje fibers are located in the left side of the heart.
When PVCs occur, they can make the heart beat or feel as if it skipped a beat. If you have only a few episodes, and there are no other symptoms your cardiologist may not treat you. But if you have a large number of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG to gauge your heart rate over the course of 24 hours. He or she may also suggest wearing a Holter monitor that records the heart's rhythm over time to determine how many PVCs you have.
People who have suffered a previous heart attack or cardiomyopathy, an illness that affects way the heart pumps blood - must take their PVCs seriously and speak to a cardiologist about lifestyle modifications. Those include the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.
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 irregular heartbeats could indicate a problem with the structure of your heart or other health conditions, and over time, when they are frequent enough, they can weaken the heart muscle. The majority of people with PVCs do not experience any problems. They just want to know that the fluttering or skipping heartbeats aren't normal.
Diagnosis
PVCs might appear to be fluttering or skip heartbeats, especially when they are frequent or intense. People who experience a lot of them may feel they're about to faint. Exercise can cause PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to study the heart and see how it's working.
A doctor may be able to identify if the patient has PVCs from a 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 monitoring systems can also assist in detecting PVCs and other arrhythmias, and could be utilized in the event of any suspicion of a cardiac condition.
If window doctors near me determines that your heart's structure is normal, reassurance is the only treatment required. If your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as reducing stress may help. Regular exercise, maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms persist or severe, talk to your physician about the medications that could help reduce these symptoms.
Treatment
If PVCs don't cause symptoms or are not frequent, they usually don't need treatment. If you experience them frequently, your doctor may want to look for any other heart problems and recommend lifestyle changes or medication. You might also get an operation to rid yourself of them (called radiofrequency catheter ablation).
If you suffer from PVCs in your heart the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can cause your heart to feel as if it skips beats or has additional beats. They're more common among people suffering from heart disease however it's unclear what causes them. PVCs may increase in frequency as you age, and they might occur more frequently during exercise.
If a patient experiences frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out structural heart disease. The doctor will also conduct an exercise stress test in order to determine if the additional heartbeats are due to physical activity. To determine whether there are any other causes for the extra beatings an invasive heart catheterization or cardiac MRI could be conducted.
The majority of people who suffer from PVCs have no complications and can live a normal life. However, they may increase your risk of having dangerous heart rhythm problems, especially if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and is having difficulty pumping blood through your body.
A healthy and balanced diet and regular exercise can help reduce your chances 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. Some medicines can also increase the risk of getting PVCs. If you are taking any of these medicines it is crucial to follow your doctor's advice regarding healthy eating and exercising as well as taking your medication.
In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. Some patients may require a heart transplant.
