How a VC Can Affect Your Heart

Many people have occasional PVCs and have no issues. If they occur regularly, PVCs can weaken your heart muscle and Penthouse Window repair increase your risk of heart failure.

The heart's rhythm is usually controlled by a bundle of nerve fibers situated in the upper right corner of your heart. This is called the sinoatrial node or SA. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs happen when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. The impulse actually starts in the ventricles and causes a mistimed heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat, or it feels like it is fluttering. They can happen infrequently without causing any symptoms, but they could occur frequently enough to impact your quality of life. If they occur frequently or cause weakness, dizziness or fatigue, your doctor might treat them with medicine.

PVCs are generally harmless and do not increase your risk of heart disease. Over time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.

PVCs can cause symptoms like a feeling of your heart skipping a beat, or fluttering. You may also feel breathless. The fluttering may be more apparent if you exercise, or consume certain foods or beverages. People who experience chronic anxiety or stress may have more PVCs and certain medications such as amiodarone, digoxin, and cocaine can increase the chance of developing them.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medication. If you have frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as caffeine and alcohol. You can also lower your stress by taking enough rest and working out.

If you've got a lot of PVCs, your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. This procedure is performed by a specialist called an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, however it does not stop them from occurring in the future. In some cases it may increase your risk of having atrial fibrillation (AFib) which can cause a stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can make your heart seem to skip or flutter one beat. These extra heartbeats are harmless, however you might be advised to consult your physician in the event of frequent heartbeats or if you are experiencing symptoms such as dizziness or fatigue.

Normally, electrical signals start in the sinoatrial node located in the upper right-hand side of the heart, and travel down to the lower chambers (or ventricles) that pump blood. Then, the ventricles contract to propel blood into your lungs, and return to the heart to begin the next pumping cycle. A PVC starts in a different location, the Purkinje fibres bundle at the left-hand side of the heart.

When PVCs occur, they make the heart pound or feel as if it skipped a beat. If you have only a few episodes, but no other symptoms, your doctor probably won't be able to treat you. But if you have a lot of PVCs, the doctor may recommend an electrocardiogram, also known as an ECG to gauge the heart's rate over a 24-hour period. He or she might also recommend wearing a Holter Monitor, which records your heartbeat and tracks the number of PVCs.

If you've had previously from a heart attack or have suffered from cardiomyopathy - an illness that affects method by which the heart pumps blood - should take their PVCs seriously and consult a cardiologist regarding lifestyle changes. Those include the avoidance of alcohol, caffeine, and smoking, managing stress and anxiety and getting enough sleep. A cardiologist can also prescribe medication to slow the heartbeat, such as beta blockers.

Even if there aren't any other indications however, you should have PVCs checked by an expert in cardiology if they occur often. These extra heartbeats can be a sign of problems with the structure of your heart or to other health conditions and, Window replacement over time, when they happen frequently enough, they can weaken the heart muscle. Most people with PVCs don't experience any issues. They just want to know that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, particularly when they are frequent or intense. People who experience them regularly may feel weak. They can also occur during training, even though many athletes who get them don't have any problems with their heart or health. PVCs can show up in tests like an electrocardiogram or a Holter monitor. They use sticky patches with sensors to record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to examine the heart and see how it's functioning.

A doctor will usually be able to determine the presence of PVCs by looking at them and taking a medical history. Sometimes it is possible that they not be aware of PVCs until they examine patients for a different reason such as following an accident or surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They are able to detect heart disease in the event of any reason to be concerned.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all that's needed. However, if your symptoms are troubling or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress can help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can help reduce the frequency of PVCs. If your symptoms continue or are severe, talk to your doctor about treatments that could help control them.

Treatment

If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If they happen frequently your doctor may be able to look for heart problems or suggest lifestyle changes. You could also have an operation (called radiofrequency cathode ablation) to get rid them.

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node, which is located in the upper right corner of your heart. It can feel like your heart skips beats or has a few extra beats. They're more common among people who suffer from heart issues however it's unclear what causes them. PVCs are more frequent with age and might happen more frequently during exercises.

A doctor should perform an ECG and an echocardiogram for a patient who has frequent and painful PVCs to identify structural heart conditions. They should also conduct an exercise stress test to determine if the extra beats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other causes of the additional beats.

Most people who suffer from PVCs do not experience any complications and can lead a normal lifestyle. However, they can increase the risk of developing dangerous heart rhythm issues, especially if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and has trouble pumping blood through your body.

A regular, healthy diet and plenty of exercise can reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat, and limit your consumption of tobacco and caffeine. Sleep and stress are also important. Certain medications can increase your risk of getting PVCs. If you take any of these medications it is crucial that you follow the advice of your doctor regarding healthy eating and exercising as well as 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 incidence of arrhythmia-induced cardiomyopathy. This can result in the need for a transplant in some people.
