How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The rhythm of your heart is usually controlled by a bundle of fibers located in the upper right-hand 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 are caused by the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. Instead, the impulse is generated in a different area of your heart, the ventricles, and causes a mistimed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or feels like it is fluttering. They may happen rarely and cause no symptoms, or they can happen often enough to interfere with your daily life. Your doctor may prescribe medicine when they occur frequently or cause weakness, dizziness or fatigue.

For the majority of people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. Over time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can lead to heart failure.

The symptoms of PVCs include a feeling that your heart beats faster or it flutters. You may feel exhausted. The fluttering may be more apparent when you exercise, or eat or drink certain drinks or foods. PVCs are more common in those suffering from chronic stress or anxiety. Certain medications, like digoxin, amiodarone, and cocaine, can increase their risk.

If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain foods and beverages, such as alcohol and caffeine. You can also lessen stress by having enough sleep and exercising.

If you have many PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells responsible for them. This is done by a specialist, known as an electrophysiologist. The treatment is generally successful in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some instances it may increase your risk of having atrial fibrillation (AFib), which can lead to stroke. This isn't common but it could be life-threatening.

Symptoms

Premature ventricular contracts or PVCs may cause your heart to skip or flutter. These extra heartbeats are generally harmless, however, you should consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness.

The electrical signals typically begin in the sinoatrial node located in the upper right portion of the heart. They travel down to the lower chambers (or ventricles) which pump blood. The ventricles then contract to force blood into the lung. They return to the center to start the next cycle of pumping. But a PVC begins in a different location, from the bundle of fibers known as the Purkinje fibers in the left-hand side of the heart.

When PVCs occur they can make the heart feel as if it's skipping a beat or pounding. If you have only just a few episodes and no other symptoms are present, your cardiologist will probably not 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 measure the heart's rate over 24 hours. He or she might also suggest wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

If you've had previously from a 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 modifications. These include avoiding caffeine, alcohol and smoking, managing anxiety and stress and ensuring adequate sleep. A cardiologist can prescribe medication to slow the heartbeat like beta blockers.

Even if you don't have any other symptoms it is still recommended to have PVCs examined by a cardiologist if they happen often. These irregular heartbeats could be a sign of a problem with the structure of your heart or lungs and if they occur frequently enough, they can weaken the heart muscle. The majority of people with PVCs do not experience any issues. They simply want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, especially when they're frequent or intense. People who experience them frequently may feel weak. Exercise can trigger them, but most athletes who suffer from them do not have heart or health issues. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors on them to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

A doctor is often able to tell 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 following an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias and they might be used in the event of any suspicion of a cardiac condition.

If your cardiologist determines that your heart's structure is normal, reassurance is the only treatment needed. If your symptoms are troubling or make you be anxious, avoiding alcohol, caffeine window and door doctor over-the drug decongestants and decreasing stress can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are severe, speak to your window & door doctor about possible treatments that could help control them.

Treatment

If PVCs aren't causing symptoms or occur rarely generally, they don't require treatment. If they occur frequently your doctor may need to examine for heart problems or suggest lifestyle adjustments. You may also undergo a procedure to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that causes your heartbeat begins somewhere other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can cause your heart to feel as if it skips a beating or has extra beats. PVCs are more prevalent among people who suffer from heart issues however, it's not clear the reason behind them. PVCs can increase in frequency with age and might happen more frequently during exercise.

A doctor should conduct an ECG along with an echocardiogram on a patient who suffers from frequent and painful PVCs to determine if there are structural heart problems. They should also conduct an exercise stress test to determine whether the extra beats are due to physical exercise. To find out whether there are any other causes for the extra beatings an invasive heart catheterization or a cardiac MRI could be conducted.

The majority of people who suffer from PVCs are not affected and can lead the normal life. They could increase your risk for heart rhythm disorders that can be dangerous, especially if they occur in certain patterns. In some instances, this means that the heart muscle gets weaker and is unable to pump blood throughout the body.

A regular, healthy diet and plenty of exercise can help reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat, and limit your consumption of tobacco and caffeine. Also, you should try to get enough sleep and reduce stress. Certain medicines can also increase your risk of PVCs. If you're taking one of these medicines it is important to follow your doctor's recommendations about eating well, exercising and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. Certain people may require an organ transplant.
