How a VC Can Affect Your Heart
PVCs are common and may be experienced by many people without causing any issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The heart's rhythm is usually controlled by a group of fibers located in the upper right-hand part of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from this node to the lower chambers of your heart, or ventricles.
Causes
PVCs are caused when the electrical impulse which normally starts 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 and causes an untimed heartbeat. These extra beats, called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or is fluttering. They can happen infrequently and cause no symptoms, or they can happen often enough to affect your daily life. If they are very frequent or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.
For most people, PVCs are harmless and aren't likely to increase your risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially the case if they are caused by a heart disease like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy, which could lead to symptoms of heart failure.
The symptoms of PVCs include feeling like your heart skips a beat or is fluttering, and you feel breathless. The fluttering may be more apparent when you exercise or consume certain beverages or foods. PVCs are more common for those who suffer from chronic anxiety or stress. Some medications, like digoxin, amiodarone, and cocaine, may increase their risk.
If you are experiencing occasional PVCs, your doctor may recommend lifestyle changes and medicines. If they are a frequent occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. You can also reduce stress by getting enough sleep and exercising.
If you've got a lot of PVCs Your doctor may suggest a medical procedure known as radiofrequency catheter ablation, which destroys the cells that cause them. This procedure is performed by a specialist known as an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms however, it doesn't prevent them from recurring in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib), an illness that can lead to stroke. It is not common, but it could be life-threatening.
Signs and symptoms
Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or to flutter. These heartbeats that are not normal can be harmless, however you might need to see your doctor when they occur frequently or if you notice symptoms such as dizziness or fatigue.
Normaly, electrical signals begin in the sinoatrial, located in the upper right-hand part of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. The ventricles then contract to propel blood into your lungs, and then return to your heart to start the next pumping cycle. However, a PVC begins in a different location and is located in the bundle of fibers, known as the Purkinje fibers in the left-hand side of the heart.
When PVCs occur they can make the heart feel as if it's beating faster or slower. If you have only just a few episodes and there are no other symptoms your cardiologist may not treat you. If you've got a lot of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG to determine your heart rate over 24 hours. They may also recommend wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.
Anyone who has suffered previously from a heart attack or cardiomyopathy - an illness that affects the heart's blood flow - should take their PVCs very seriously and speak to a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.
Even if there aren't any other indications however, you should have PVCs checked by an cardiologist if they occur frequently. These extra heartbeats may indicate a problem in the structure of your lungs or heart, and if they happen often enough, can weaken your heart muscle. Most people who suffer from PVCs don't experience any issues. They would like to know if rapid heartbeats, or the skipping of heartbeats is normal.
Diagnosis
PVCs might appear to be fluttering or skip heartbeats, particularly when they're frequent or intense. People who experience a lot of them may feel they're about to faint. They can also occur with exercise, though many athletes who get them do not have any issues with their heart or health. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining the heart.
A doctor may be able to determine if the patient is suffering from PVCs from a patient's history and physical exam. Sometimes however, they might only be able to detect PVCs when they examine a patient for another reason such as following an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and could be utilized if there's any concern of heart disease.
If your cardiologist determines your heart is structurally healthy, reassurance could be all you need. However, if your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine and other decongestants and reducing stress may 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 medication that could be able to manage them.
Treatment
If PVCs are rare or don't cause symptoms, they do not usually require treatment. If they occur frequently, your doctor might want to check for heart conditions or recommend lifestyle adjustments. You could also have a procedure (called radiofrequency cathode ablation) to eliminate them.
If you suffer from PVCs The electrical signal that causes your heartbeat is generated from a place outside of the sinoatrial node (SA node) in the top right side of your heart. This could cause your heart to feel as if it skips a beating or has extra beats. PVCs are more prevalent among people who suffer from heart issues, but it's not known what causes them. PVCs may increase in frequency as you age, and may be more frequent during exercising.
A physician should perform an ECG along with an echocardiogram on a patient who has frequent and painful PVCs to identify structural heart conditions. They will probably also do an exercise stress test to determine whether the extra beats are caused by physical exercise. To find out if there are other causes for the extra beats the heart catheterization or cardiac MRI can be performed.
The majority of people with PVCs do not have any issues and can live a normal life. However, window doctors can increase your risk of having dangerous heart rhythm issues, especially if you have certain patterns of them. In some cases, that means that the heart muscle becomes weaker and has trouble pumping blood throughout your body.
Regular exercise and a healthy diet can lower your risk of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of tobacco and caffeine. You should also try to get enough sleep and manage stress. Some medicines may also increase your risk for PVCs. If you take any of these medications it is crucial that you follow the advice of your doctor regarding healthy eating exercising, as well as taking your medication.
In studies of patients with PVC burdens that are high (more than 20% of total heartbeats) the higher rate of arrhythmia-induced myopathy in the heart was observed. Certain people may require an organ transplant.
