How a VC Can Affect Your Heart
Many people experience occasional PVCs with no problems. If they occur often, PVCs may weaken your heart and increase the chance of suffering from heart failure.
The heart's rhythm is usually controlled by a group of fibers located in the upper right part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower chambers of your heart, or ventricles.
Causes
PVCs occur when the electrical impulse that usually starts your heartbeat in a part called the sinus node (also known as the sinoatrial or SA node) does not. Instead, the impulse is generated in a different part of your heart--the ventricles--and causes a mistimed beat. These extra beats are also known as ventricular tachycardia, and ventricular fibrillation. It may feel like the heart beats faster or feels fluttering. They can happen infrequently without causing any symptoms, but they may occur frequently enough to affect your standard of living. Your doctor may prescribe medication in the event that they are frequent or cause weakness, dizziness or fatigue.
Repair My Windows And Doors UK are generally safe and do not increase your risk of heart disease. A lot of PVCs, however, can weaken the heart muscle over time. This is especially true if the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.
The symptoms of PVCs include feeling like your heart beats slower or flutters, and you may feel breathless. The fluttering may be more evident when you exercise or eat or drink certain drinks or foods. People who suffer from chronic anxiety or stress may have more PVCs and certain drugs like amiodarone digoxin, and cocaine can increase the likelihood of developing them.
If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication. If you are prone to frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, like caffeine and alcohol. You can also take steps to reduce your stress, and get plenty of sleep and exercise.
If you're suffering from many PVCs, he may suggest a medical treatment called radiofrequency catheter ablation. This destroys the cells that are responsible for PVCs. This procedure is performed by a specialist, known as an electrophysiologist. It is generally effective in treating PVCs and reducing symptoms but it doesn't stop them from recurring in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib) which is an illness that can lead to stroke. This is rare but can be life-threatening.
Signs and symptoms
Premature ventricular contracts or PVCs may cause your heart to skip or flutter. These extra heartbeats are generally harmless, but you should talk to your doctor in case you experience frequent episodes or signs like dizziness or weakness.
Normally, electrical signals start in the sinoatrial node, which is in the top right portion of the heart, and travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to pump blood into the lung. They then return to the center to begin the next cycle of pumping. A PVC begins in a different place that is the Purkinje fibers are located in the left-hand side of the heart.
When PVCs occur, they can make the heart pound or feel as if it skipped the beat. If you only have a few episodes, and there are no other symptoms the cardiologist will likely not be able to treat you. If you have a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. He or she may also recommend wearing a Holter monitor, which will record your heart rhythm over time to see the number of PVCs you have.
Anyone who has had a prior heart attack or suffer from cardiomyopathy -which affects the way that the heart pumps blood - should be aware of their PVCs and talk to a cardiologist about lifestyle changes. These include abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, and getting enough rest. A cardiologist can also prescribe medication to slow the heartbeat, such as beta blockers.
If you have frequent PVCs even if do not have other symptoms, you should consult a cardiologist. These irregular heartbeats could be a sign of a problem with the structure of your heart or other health issues, and over time, if they occur often enough, they could weaken the heart muscle. Most people with PVCs do not have any issues. They are interested in knowing if the irregular heartbeats or fluttering is normal.
Diagnosis
PVCs might feel like fluttering or skipped heartbeats, particularly when they're intense or frequent. People who experience them regularly may feel faint. They can also occur during training, even though many athletes who experience them do not have any issues in their heart or health. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to examine the heart and see how it's working.
A doctor can often tell if a patient has PVCs by examining them and taking their medical history. Sometimes, however, they may not be aware of PVCs until they examine patients for a different reason, such as after an accident or a surgery. Ambulatory ECG monitoring systems can also aid in detecting PVCs and other arrhythmias, and they might be used in the event of any suspicion of cardiac disease.
If your cardiologist determines that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are bothersome or make you feel anxious, avoiding alcohol, caffeine, and over the counter decongestants, and the reduction of stress could help. Regular exercise, being at a healthy weight and drinking enough water can decrease the likelihood of PVCs. If your symptoms are persistent or severe, talk to your physician about the medications that may be able to reduce these symptoms.
Treatment
If PVCs don't cause symptoms or happen rarely generally, they don't require treatment. If you are frequently affected or frequently, your doctor may wish to examine for any other heart problems and recommend lifestyle changes or medication. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).
If you have PVCs the electrical signal that causes your heartbeat is generated from a place other than the sinoatrial node (SA node) in the top right corner of your heart. This can cause your heart to feel as if it skips a beating or has additional beats. PVCs are more frequent among those who suffer from heart issues however, it's not clear what causes them. PVCs may increase in frequency as you age, and could be more frequent during exercising.
A doctor should perform an ECG along with an echocardiogram on a patient who has frequent and painful PVCs to rule out structural heart diseases. The doctor will also likely conduct an exercise stress test in order to determine if the extra heartbeats are caused by physical exercise. To determine whether there are other reasons for the extra beats an invasive heart catheterization or a cardiac MRI can be performed.
The majority of people who suffer from PVCs do not have any issues and can live a normal life. They may increase the risk of heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some cases, that means that your heart muscle gets weaker and has trouble pumping blood throughout your body.
Regular exercise and a healthy diet can lower your risk of developing PVCs. You should avoid foods that are high in fat and sodium and limit caffeine and tobacco. It is also important to sleep enough and reduce stress. Certain medicines can also increase your risk of getting PVCs. If you're taking one of these medications, it's important to follow your doctor's instructions about a healthy diet, exercise and taking your medication.
In studies of patients with PVC burdens that are excessive (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. This can lead to a need for a heart transplant in certain patients.
