How a VC Can Affect Your Heart

PVCs are common and may be experienced by a variety of people without causing any issues. If they occur often, PVCs may weaken your heart and increase your risk of heart failure.

The heart's rhythm is usually controlled by a bundle of fibers that are located in the upper right part 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 are caused when the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different part of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, called ventricular tachycardia or new ventricular fibrillation, can feel like your heart skipped a beat, or it feels like it is fluttering. They may occur infrequently, causing no symptoms, but they could also happen frequently enough to affect your quality of life. If they happen frequently or cause dizziness, weakness, or fatigue, your doctor might treat them with medication.

In most people, PVCs are harmless and don't increase your risk of heart disease or other health issues. Frequent PVCs however, may weaken your heart muscle over time. This is particularly the case if they are caused by a heart-related condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

PVCs can trigger symptoms, such as a sensation of your heart racing one beat, or even the feeling of your heart fluttering. It is also possible to feel breathless. The fluttering could be more evident when you exercise or consume certain drinks or foods. PVCs are more common in people with chronic stress or anxiety. Some drugs, like digoxin, amiodarone or cocaine, can increase the risk.

If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medications. If they are a regular occurrence, you may have to stay clear of certain foods and beverages like alcohol and caffeine. You can also reduce your stress, and take advantage of plenty of rest and Commercial Window Repair exercise.

If you've got a lot of PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation, which eliminates the cells responsible for them. This is done by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs and reducing symptoms, but does not prevent them from recurring in the future. In some cases, it can increase the risk of developing atrial fibrillation (AFib) which could result in stroke. It is not common, but it can be life-threatening.

Symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or to flutter. These extra heartbeats are harmless, however you might need to see your doctor if they are frequent or if you experience symptoms such as dizziness or fatigue.

The electrical signals typically begin in the sinoatrial node located in the upper right side of the heart, Custom Window Repair and descend to the lower chambers (or ventricles) which pump blood. Then, the ventricles expand to push blood into your lungs and then return to the heart to start the next pumping cycle. However, a PVC starts in a different place and is located in the bundle of fibers known as the Purkinje fibers in the lower left part of the heart.

When PVCs happen and the heart is affected, it may appear to be racing or pounding. If you only have a few episodes, and no other symptoms are present your cardiologist may not be able to treat you. If you have many PVCs, your doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. The doctor may also suggest wearing a Holter monitor, which will record your heartbeat over time, allowing you to see how many PVCs you have.

If you've had a previous heart attack or have suffered from cardiomyopathy - an illness that affects way the heart pumps blood - should take their PVCs seriously and consult an expert in cardiology about lifestyle changes. These include abstaining from caffeine, alcohol, and Window Glass Repair smoking, reducing stress and anxiety, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.

If you have frequent PVCs, even if you do not have other signs, you should see a cardiologist. These extra heartbeats may be a sign of a problem with the structure of your lungs or heart, and if they happen often enough, can weaken the heart muscle. However, most people suffering from PVCs don't have any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs might feel like fluttering or skipped heartbeats, especially if they're frequent or intense. People who experience them frequently may feel faint. They can also occur with exercise, though many athletes who suffer from them don't have issues with their heart or health. PVCs can show up in tests like an electrocardiogram or a Holter monitor. These patches have sensors which record electrical impulses that come from your heart. A cardiologist may also perform an echocardiogram, which makes use of ultrasound to look at the heart and see how it's working.

A doctor may be able to determine if someone is suffering from PVCs from a history and physical examination. Sometimes however, they might not be aware of PVCs until they examine the patient for another reason such as following an accident or surgical procedure. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect cardiac disease if there is any concerns.

If your cardiologist concludes that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are causing discomfort or make you feel anxious, avoiding caffeine, alcohol and over-the-counter decongestants as well as reducing stress levels can help. Getting regular exercise, staying at a healthy weight, and drinking enough water can also reduce your episodes of PVCs. If your symptoms are persistent or severe, talk to your doctor about medications that could help reduce the symptoms.

Treatment

If PVCs aren't causing symptoms or occur rarely they aren't usually in need of treatment. If they happen frequently your doctor may want to check for heart problems or suggest lifestyle adjustments. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

When you have PVCs the electrical signal that triggers your heartbeat begins somewhere outside of the sinoatrial node (SA node) located in the upper right part of your heart. This can make it feel like your heart skips a beat or Window weatherstripping is beating faster. It's not clear what causes these, but they're more common in people who have other heart issues. PVCs can become more frequent as you age, and may be more frequent during exercising.

If a patient is experiencing frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to see if the extra beats are a result of physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes of the extra beats.

Most people with PVCs do not experience any complications and can lead an ordinary life. They could increase the risk of developing dangerous heart rhythm disorders particularly if they develop in certain patterns. In some cases, that means that the heart muscle becomes weaker and is unable to pump blood through your body.

A regular, healthy diet and plenty of exercise can reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium and restrict your intake of tobacco and caffeine. Stress and sleep are also important. Some medicines may also increase the risk of developing PVCs. If you take any of these medications it is crucial that you follow your doctor's recommendations about eating healthy exercising, as well as taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. Some patients may require a heart transplant.
