How a VC Can Affect Your Heart
PVCs are common and can be experienced by a variety of 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 usually controlled by a group of nerve fibers situated in the upper right-hand part of your heart. This is known as the sinoatrial node, or SA. Electrical signals travel to the ventricles or lower chambers of your heart.
Causes
PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. Instead, the impulse is generated in another area of your heart--the ventricles--and causes an untimed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beating or feels like it is fluttering. They can happen infrequently and not cause any symptoms, but they can also happen frequently enough to impact your quality of living. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor could treat them with medicine.
PVCs are generally harmless and don't increase your risk of heart disease. Frequent PVCs, however, can weaken the heart muscle over time. This is especially relevant if the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.
The signs of PVCs include feeling like your heart beats slower or flutters, and you may feel breathless. The fluttering could be more noticeable when you exercise or consume certain drinks or foods. People with chronic anxiety or stress may have more PVCs and certain medications such as amiodarone, digoxin and cocaine can increase the risk of developing them.
If you are experiencing occasional PVCs Your doctor may recommend lifestyle changes and medicines. If you are prone to frequent PVCs, your physician may recommend avoiding certain foods and drinks, such as alcohol and caffeine. You can also reduce your stress levels by getting enough sleep and working out.
If you're experiencing many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. It eliminates the cells that cause PVCs. The procedure is carried out by a specialist known as an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms, however it does not stop them from recurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib) which could result in a stroke. It's not common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions, or PVCs, can make your heart seem to flutter or skip the beat. These extra heartbeats are generally harmless, however, you should talk to your doctor when you experience frequent episodes or signs like dizziness or weakness.
The electrical signals typically begin in the sinoatrial node, which is in the top right portion of the heart. They descend to the lower chambers (or ventricles) that pump blood. The ventricles then contract to propel blood into your lungs and then return to the heart and start the next pumping cycle. A pvc Doctor starts in a different place in the Purkinje fibers are located in the left side of the heart.
When PVCs occur, they make the heart beat or feel like it skipped a beat. If you experience only a few episodes, and no other symptoms are present, your cardiologist will probably not prescribe treatment. If you have a lot of PVCs, your bifold doctor may recommend that you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. The doctor might also recommend wearing a Holter monitor, which will record the heart's rhythm over time, allowing you to see how many PVCs you have.
Anyone who has had a prior heart attack or suffer from cardiomyopathy -which alters the way the heart pumps blood- should take their PVCs seriously and consult a cardiologist about changes to their lifestyle. These include abstaining from 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 experience any other indications, you should still get PVCs examined by a cardiologist if they happen frequently. These irregular heartbeats could indicate problems with the structure of your heart or to other health conditions and, over time, when they happen frequently enough, they could weaken the heart muscle. Most people with PVCs do not experience any issues. They would like to know if irregular heartbeats or fluttering is normal.
Diagnosis
PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them often might feel faint. Exercise can cause PVCs, but a lot of athletes who experience these symptoms do not have heart or health problems. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which uses ultrasound to study the heart and observe how it's working.
A door doctor can often tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason, such as after an accident or surgical procedure. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and can be used when there is a concern of heart disease.
If your cardiologist concludes that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are bothersome or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If your symptoms are persistent or extreme, consult your doctor about medication that may be able to reduce the symptoms.
Treatment
If PVCs are rare or don't cause symptoms, they rarely require treatment. If they occur frequently, your doctor might want to check for heart problems or suggest lifestyle changes. You could also have an operation (called radiofrequency cathode ablation) to eliminate of them.
If you suffer from PVCs in your heart, the electrical signal which causes your heartbeat begins somewhere other than at the sinoatrial (SA) node that is located in the upper right corner of your heart. This can make it feel like your heart skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease however, it's not clear the reason behind them. PVCs may increase in frequency as you age, and they may be more frequent during exercise.
If a patient experiences frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also likely perform an exercise stress test to determine if the additional heartbeats are related to physical exercise. To find out if there are other causes for the increased beats, a heart catheterization or a cardiac MRI could be conducted.
Most people who suffer from PVCs do not have any issues and live an ordinary life. However, they may increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In some cases this means that the heart muscle gets weaker and is unable to pump blood throughout the body.
A healthy, regular diet and plenty of exercise can reduce the chances of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. It is also important to get enough rest and reduce stress. Certain medicines can also increase the risk of getting PVCs. So if you take one of these medications, it's important to follow the doctor's advice about eating well, the door Doctor exercising and taking your medication.
In studies of patients with high PVC burdens (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. Certain people may require a heart transplant.
