How a VC Can Affect Your Heart
Many people have occasional PVCs and have no issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.
A bundle of fibers in the double glazing doctor top right portion of your heart (the sinoatrial, or SA, node) typically regulates the heart's rhythm. Electrical signals travel to ventricles or lower chambers of your heart.
Causes
PVCs occur when the electrical impulse that typically initiates your heartbeat at a point known as the sinus node (also known as the sinoatrial or SA node) doesn't. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat or feels fluttering. They can occur rarely, causing no symptoms, but they could be frequent enough to affect your standard of living. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor may treat them with medication.
PVCs are generally harmless and don't increase your risk of developing heart disease. Regular PVCs however, may weaken your heart muscle over time. This is particularly the case if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.
The signs of PVCs include a feeling that your heart beats faster or flutters, and you may feel breathless. The fluttering can be more noticeable when you exercise or consume certain foods or beverages. PVCs are more common in people with chronic stress or anxiety. Certain medications, like digoxin, amiodarone or cocaine, may increase the risk.
If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medication. If you experience frequent PVCs, your doctor might recommend avoiding certain foods and drinks, such as caffeine and alcohol. You can also take steps to lessen your stress and get plenty of sleep and exercise.
If you have many PVCs Your doctor might suggest a medical procedure called 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 generally successful in treating PVCs, reducing symptoms but it does not stop them from returning in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib) which could cause stroke. It is not common however it could be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs, can make your heart seem to flutter or skip one beat. These extra heartbeats are usually harmless, but it is important to talk to your doctor if you have frequent episodes or other symptoms such as dizziness or weakness.
The electrical signals typically begin in the sinoatrial node, located in the upper right-hand side of the heart, and move down to the double glazing doctor lower chambers (or ventricles) that pump blood. Then, the ventricles expand to push blood into your lungs, and return to the heart and start the next cycle of pumping. A Pvc doctor starts in a different location in the Purkinje fibers are located in the bottom left of the heart.
When PVCs happen and the heart is affected, it may feel as if it's racing or pounding. If you have only a few episodes, but no other symptoms, the doctor will probably not treat you. If you've got a lot of PVCs the glass doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor, which records your heartbeat window and door doctor tracks the number of PVCs.
If you've had an earlier heart attack or cardiomyopathy, an illness that affects method by which the heart pumps blood - should take their PVCs seriously and speak to a cardiologist about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medication to slow the heartbeat, like a beta blocker.
Even if you don't experience any other indications, you should still get PVCs examined by an expert in cardiology if they occur often. These extra heartbeats may indicate a problem in the structure of your heart or lungs and if they happen often enough, it could weaken your heart muscle. But most people with PVCs don't have any issues. They simply want to know that the fluttering or racing heartbeats aren't normal.
Diagnosis
PVCs can feel like heartbeats that are fluttering particularly if they're frequent and intense. People who experience them regularly may feel weak. They can also happen with exercising, but most athletes who get them do not have any issues with their heart or health. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors which record electrical impulses that come from your heart. A cardiologist may also use an ultrasound echocardiogram to study the heart.
A doctor will usually be able to determine if a patient has PVCs by looking at them and taking a medical history. Sometimes however, they might not be aware of PVCs until they examine the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias and they might be used if there's any concern of a cardiac condition.
If your cardiologist concludes that your heart's structure is normal, reassurance will be the only remedy required. If your symptoms are causing you discomfort, or cause you to feel anxious, staying away from alcohol, caffeine and over-the drug decongestants and the reduction of stress could aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can aid in reducing the frequency of PVCs. If your symptoms continue or are extreme, talk to your doctor about possible medication options to treat them.
Treatment
If PVCs don't cause symptoms or occur rarely, they usually don't need treatment. If you experience them frequently, your doctor may want to examine for other heart conditions and recommend lifestyle changes or medications. You could also have an intervention to get rid of them (called radiofrequency catheter ablation).
If you have PVCs, the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial nerve (SA node) located in the upper right side of your heart. It can feel like your heart skips beats or has extra beats. PVCs are more frequent among those with heart problems however, it's not clear what causes them. PVCs are more frequent with age and might happen more often during exercising.
A doctor should conduct an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to identify structural heart conditions. The doctor will also perform an exercise stress test in order to determine if the increased heartbeats are caused by physical exercise. To determine whether there are any other causes for the increased beats, a heart catheterization or an MRI could be conducted.
Most people with PVCs have no complications and live a normal life. They may increase the risk of developing heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some cases, this means that the heart muscle gets weaker and it is more difficult to pump blood throughout your body.
A healthy, regular diet and plenty of exercise can reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat, and you should also reduce your intake of caffeine and tobacco. Also, you should try to get enough sleep and manage stress. Some medicines can also increase the risk of developing PVCs. If you are taking any of these medications, it is important to follow the advice of your doctor about eating healthy, exercising, and taking your medication.
Studies of patients suffering from a high amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
