How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people with no cause for concern. If they happen frequently, PVCs may weaken your heart and increase your risk of heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial or SA node) typically regulates the heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers or ventricles.

Causes

PVCs occur when the electrical impulse that normally begins your heartbeat at a point called the sinus node (also called the sinoatrial or SA Node) doesn't. The impulse actually starts in the ventricles and causes an untimed heartbeat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat, or it feels like it is fluttering. They can occur infrequently and cause no symptoms, or they can happen often enough to affect your daily life. If they occur frequently or cause weakness, dizziness or fatigue, your doctor could treat them with medicine.

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

The signs of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel exhausted. The fluttering may be more evident when you exercise or consume certain drinks or food items. PVCs are more common for those who suffer from chronic stress or anxiety. Some medications, such as digoxin, amiodarone and cocaine, can increase their risk.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medications. If they are a frequent occurrence, you may have to stay clear of certain drinks and foods like caffeine and alcohol. You can also lessen your stress by having enough sleep and working out.

If you're suffering from many PVCs, he may suggest a medical procedure called radiofrequency catheter ablation, which destroys the cells that are responsible for PVCs. Electrophysiologists are the ones who execute this procedure. The treatment is generally effective in treating PVCs, reducing symptoms but it does not stop them from recurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib) which is a condition that can lead to stroke. It is not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, or PVCs, may make your heart seem to skip or flutter one beat. These extra heartbeats are harmless, however you might want to consult your doctor in the event of frequent heartbeats or if you are experiencing symptoms like dizziness, or fatigue.

The electrical signals typically begin in the sinoatrial node located in the upper right-hand Stained Glass fix double pane window low-e window repair (Telegra.Ph) side of the heart. These signals travel down to the lower chambers (or ventricles) which pump blood. The ventricles expand to push blood into your lungs and return to the heart to begin the next cycle of pumping. A PVC starts in a different location in the Purkinje fibres bundle in the bottom left of the heart.

When PVCs occur, they can make the heart pound or feel as if it skipped a beat. If you've experienced a few episodes and no other symptoms, the doctor probably won't be able to treat you. If you have many PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. He or she may also recommend wearing a Holter monitor that records your heart rhythm over time, allowing you to see how many PVCs you have.

Anyone who has had a prior heart attack or have cardiomyopathy -which affects how the heart pumps blood -- should be aware of their PVCs and talk to a cardiologist about changes to their lifestyle. This includes abstaining from caffeine, alcohol, and smoking, managing anxiety and stress, and getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.

Even if there aren't any other indications however, you should have PVCs checked by an expert in cardiology if they occur frequently. These extra heartbeats may indicate a problem in the structure of your heart or lungs, and if they occur often enough, can weaken your heart muscle. However, most people with PVCs don't experience any problems. They want to know 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 a lot of them might feel like they're going to faint. They can also occur with training, even though many athletes who get them don't have issues with their health or heart. PVCs may show up in tests like an electrocardiogram or a Holter monitor. These are sticky patches that have sensors that record electrical impulses coming from your heart. A cardiologist may also use an ultrasound echocardiogram for examining the heart.

A doctor will usually be able to determine the presence of PVCs by examining them and taking their medical history. However, sometimes they will only notice them while examining the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitoring systems can also help detect PVCs and other arrhythmias, and could be utilized when there is a concern of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance could be all you need. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress may aid. Getting regular exercise, staying at a healthy weight, and drinking enough water can also help reduce the frequency of PVCs. If your symptoms continue or are severe, speak to your doctor about possible medications that can control the symptoms.

Treatment

If PVCs aren't causing symptoms or occur rarely, they usually don't need treatment. If they happen frequently, your doctor might be able to look for heart issues or suggest lifestyle adjustments. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).

If you have PVCs, the electrical signal that triggers your heartbeat is generated from a place other than the sinoatrial node (SA node) located in the upper right corner of your heart. This can make it feel like your heart skips a beat or has extra beats. They're more common among people who suffer from heart issues however, it's not clear the reason behind them. PVCs are more likely to occur as you age, and they could be more frequent during exercising.

If a patient experiences frequent and painful PVCs, a physician should conduct an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also likely conduct an exercise stress test in order to determine if the additional heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for Storm window repair other reasons for the extra beats.

Most people with PVCs do not experience any issues and can live a normal lifestyle. But they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and is having difficulty pumping blood through your body.

A healthy, regular diet and plenty of exercise can help reduce your chances of developing PVCs. You should avoid foods that are high in fat and sodium and limit caffeine and tobacco. Stress and sleep are also crucial. Certain medicines can also increase your risk for PVCs. If you take any of these medications, it is important that you follow your doctor's advice regarding eating a healthy diet and exercising as well as taking your medication.

Studies of patients with an excessive amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher risk of arrhythmia-induced cardiomyopathy. This could lead to the need for a heart transplant in certain patients.
