How a VC Can Affect Your Heart

Many people have occasional PVCs without any problems. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers in the top right portion of your heart (the door doctor sinoatrial or SA node) usually controls your heart rhythm. Electrical signals travel from this node to the lower heart chambers or ventricles.

Causes

PVCs are caused when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) is not initiated. Instead, the impulse is generated in a different part of your heart, the ventricles, and causes a wrongly timed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart beats faster or feels like it is fluttering. They can happen infrequently and not cause any symptoms, but they can also happen frequently enough to impact your quality of life. If they occur frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medication.

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

The signs of PVCs include feeling like your heart beats faster or flutters, and you may feel breathless. The fluttering could be more apparent when you exercise or have certain drinks or food items. People who experience chronic stress or anxiety can 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 windows might suggest lifestyle changes and medications. If they're a frequent occurrence, you may have to avoid some drinks and foods, such as caffeine and alcohol. You can also take steps to lessen your stress levels, and make sure you get enough sleep and exercise.

If you've got a lot of PVCs Your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. Electrophysiologists are the ones who carry out this procedure. It is typically successful in treating the PVCs and reducing symptoms, however, it doesn't prevent them from occurring in the future. In some instances it may increase your risk of atrial fibrillation (AFib) which could lead to stroke. It is not common, but it could be life-threatening.

Symptoms

Premature ventricular contractures, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats can be harmless, but you might want to consult your doctor if they are frequent or if you experience symptoms such as dizziness or fatigue.

The electrical signals typically begin at the sinoatrial junction, located in the upper right side of the heart. They move down to the lower chambers (or ventricles) which pump blood. The ventricles contract to propel the blood into your lungs, and return to the heart and start the next pumping cycle. A PVC begins 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 like it skipped the beat. If you've experienced only a few episodes, but no other symptoms, the cardiologist probably won't treat you. If you have many PVCs and your doctor window might recommend that you undergo an electrocardiogram (ECG) to monitor your heartbeat over the course of 24 hours. He or she might also recommend wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has suffered a previous heart attack or have suffered from cardiomyopathy - an illness that affects the method by which the heart pumps blood - should take their PVCs seriously and speak to an expert in cardiology about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs even if you don't have any other symptoms you should see a cardiologist. These heartbeats that are irregular can be a sign of problems with the structure of your heart or to other health conditions and, over time when they happen frequently enough, they may weaken the heart muscle. The majority of people with PVCs don't experience any problems. They just want to know that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs might be felt as fluttering or skipped heartbeats, particularly when they're frequent or intense. People who experience a lot of them may feel they're going to faint. Exercise can cause PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. PVCs can be detected 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 could also employ an ultrasound echocardiogram for examining the heart.

A doctor is often able to tell the presence of PVCs by conducting a thorough examination and taking a medical history. However, sometimes they will only notice them while examining the patient for different reasons, like following an accident or surgery. 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 that's needed. If your symptoms are causing discomfort or make you feel anxious, staying away from alcohol, caffeine, and other decongestants as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms persist or are severe, speak to your doctor about medications that can control these symptoms.

Treatment

If PVCs don't cause symptoms or occur rarely generally, they don't require treatment. If they are frequent, your doctor might want to check for heart conditions or recommend lifestyle adjustments. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.

If you have PVCs the electrical signal that causes your heartbeat begins somewhere outside of the sinoatrial node (SA node) in the top right corner of your heart. This can make it feel like your heart skips a beat or has a few extra beats. It's unclear what causes these, but they're more common in people who have other heart issues. PVCs may increase in frequency as you age, and may occur more often during exercising.

A doctor should conduct an ECG as well as an echocardiogram for a patient who has frequent and painful PVCs to determine if there are structural heart problems. The doctor may also conduct an exercise stress test to determine if the extra heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion study could be done to look for other reasons for the increased beats.

Most people who suffer from PVCs do not suffer from any issues and can live a normal lifestyle. However, they may increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In some cases this means that the heart muscle becomes weaker and is unable to pump blood throughout your body.

A healthy, regular diet and a lot of exercise can reduce the chances of developing PVCs. You should avoid foods that are high in fat and sodium as well as limit caffeine and tobacco. You should also try to sleep enough and reduce stress. Some medicines may also increase your risk of getting PVCs. If you are taking any of these medicines, it is important to follow your doctor's advice about eating healthy exercising, as well as taking your medication.

In studies of patients suffering from Pvc doctor burdens that are high (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced myopathy in the heart was observed. Certain people may require a heart transplant.
