How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. If they happen frequently, PVCs may weaken your heart and increase the risk for heart failure.

The rhythm of your heart is controlled by a group of nerve fibers situated in the upper right corner of your heart. This is known as the sinoatrial node or SA. Electrical signals travel from there to the lower heart chambers or ventricles.

Causes

PVCs happen when the electrical impulse that usually starts your heartbeat in a region called the sinus node (also known as the sinoatrial or SA node) isn't. The impulse actually starts in the ventricles and condo Window Repair causes an untimed heartbeat. These extra beats, also called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat or feels like it's fluttering. They can happen infrequently and have no symptoms or they can occur frequently enough to interfere with your quality of life. Your doctor may prescribe medicine when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally safe and do not increase your risk of heart disease. Frequent PVCs, however, can weaken your heart muscle over time. This is especially the case if they are caused by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

The symptoms of PVCs include a feeling that your heart beats slower or is fluttering, and you feel exhausted. The fluttering can be more evident when you exercise, or eat or drink certain beverages or foods. PVCs are more prevalent in people with chronic anxiety or stress. Certain medications, such as digoxin, amiodarone or cocaine, may increase their risk.

If you have occasional PVCs Your doctor may suggest lifestyle changes and medication. If they are a regular occurrence, you may need to stay clear of certain drinks and foods, egress window Repair such as alcohol and caffeine. You can also take steps to reduce your stress and get plenty of sleep and exercise.

If you're experiencing many PVCs The doctor may suggest a medical treatment called radiofrequency catheter ablation, which destroys cells that cause PVCs. This is done by a specialist called an electrophysiologist. It is usually effective in treating PVCs and reducing symptoms however it does not stop them from recurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which can result in stroke. This is rare however it could be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, can make your heart seem to skip or flutter a beat. These extra heartbeats can be harmless, but you might be advised to consult your physician in the event of frequent heartbeats or if you notice symptoms like dizziness, or fatigue.

The electrical signals typically begin in the sinoatrial node located in the top right side of the heart. These signals move down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to propel the blood into the lungs, and then return to the heart to start the next cycle of pumping. A PVC starts in a different place that is the Purkinje fibers are located in the left-hand side of the heart.

When PVCs occur, they make the heart pound or feel as if it skipped one beat. If you experience only a few episodes, and there are no other symptoms your cardiologist may not treat you. If you've got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor that records the heart's rhythm and count the number of PVCs.

Anyone who has had a prior heart attack or have cardiomyopathy -which affects how the heart pumps blood -and should take their PVCs seriously and talk to a cardiologist about changes to their lifestyle. These include abstaining from alcohol, caffeine and smoking, managing stress and anxiety and ensuring adequate sleep. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs, even if you do not have any other signs, you should see a cardiologist. These irregular heartbeats could be a sign of problems with the structure of your heart or other health conditions and, over time if they occur often enough, they can weaken the heart muscle. But most people with PVCs don't experience any problems. They simply want to be aware that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs may feel like heartbeats that are fluttering, especially if they are frequent and Wooden Window Repair intense. People who experience them regularly may feel weak. Exercise can cause PVCs, but a lot of athletes who experience these symptoms do not have heart or health problems. PVCs may show up in tests like an electrocardiogram, or Holter monitor. These patches have sensors that record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.

A doctor will usually be able to determine whether a patient has PVCs by examining them and taking their medical history. Sometimes, they may only notice them while examining the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They may be used to detect cardiac disease in the event of any concern.

If your cardiologist determines that your heart's structure is normal, reassurance will be the only treatment required. However, if your symptoms are bothersome or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can aid. Getting regular exercise, staying at a healthy weight and drinking enough fluids can reduce your episodes of PVCs. If your symptoms are persistent or severe, speak to your physician about the medications that may be able to manage them.

Treatment

If PVCs are rare or don't cause symptoms, they rarely require treatment. If they occur frequently your doctor may want to check for heart problems or suggest lifestyle modifications. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate them.

If you have PVCs The electrical signal that triggers your heartbeat begins somewhere outside of the sinoatrial node (SA node) in the top right corner of your heart. This can cause your heart to feel as if it skips beats or has additional beats. It's unclear what causes them, but they're more common in people who have other heart conditions. PVCs can become more frequent as you age, and they may be more frequent during exercising.

A doctor should perform an ECG along with an echocardiogram on a patient that suffers from frequent and painful PVCs to rule out structural heart diseases. The doctor will also conduct an exercise stress test to determine if the additional heartbeats are related to physical activity. To find out whether there are any other causes for the extra beats the heart catheterization or an MRI is possible.

The majority of people who suffer from PVCs do not suffer from any problems and can enjoy a normal lifestyle. They could increase the risk of dangerous heart rhythm disorders particularly if they happen in certain patterns. In some instances, this means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

Regular exercise and a balanced diet will reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of caffeine and Office Window Repair tobacco. Sleep and stress are also crucial. Certain medicines can also increase your risk of getting PVCs. So if you take one of these medications it is important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication.

Studies of patients suffering from a high burden of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some people may need a heart transplant.
