How a VC Can Affect Your Heart

Many people have occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle 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) usually controls your heart's rhythm. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs are caused when the electrical impulse that typically initiates your heartbeat in a part known as the sinus node (also known as the sinoatrial or SA Node) does not. Instead, the impulse begins in another area of your heart called the ventricles and triggers an untimed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or is like it is fluttering. They can occur rarely without causing any symptoms, but they could also happen frequently enough to affect your standard of living. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medicine.

For the majority of people, PVCs are harmless and don't increase your risk of heart disease or other health problems. A lot of PVCs however, could weaken the heart muscle over time. This is especially the case if they are caused by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.





The signs of PVCs include feeling like your heart skips a beat or flutters, and you may feel exhausted. The fluttering may be more noticeable when you exercise or have certain drinks or foods. PVCs are more common for those who suffer from chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, can increase the risk.

If you experience occasional PVCs Your doctor might recommend lifestyle changes and medicines. If they're a frequent occurrence, you may need to avoid certain foods and beverages, such as alcohol and caffeine. window doctors can also lessen your stress levels by having enough sleep and working out.

If you have a lot of PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. It eliminates the cells responsible for them. Electrophysiologists are the ones who carry out this procedure. The treatment is generally successful in treating PVCs which reduce symptoms, but it does not stop them from becoming recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib), a condition that can cause stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, may make your heart appear to flutter or skip one beat. These heartbeats that are not normal can be harmless, but you may be advised to consult your physician if they are frequent or if you are experiencing symptoms like dizziness or fatigue.

The electrical signals typically begin in the sinoatrial node, located in the top right-hand side of the heart. They move down to the lower chambers (or ventricles) which pump blood. The ventricles expand to push the blood into the lungs. They return to the heart's center to begin the next cycle of pumping. A PVC starts at a different spot, the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs happen, the heart may appear to be skipping a beat or pounding. If you only have a few episodes, and no other symptoms are present the cardiologist will likely not be able to treat you. If you have a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. They may also recommend wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.

Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -which alters the way the heart pumps blood- should be aware of their PVCs and talk to an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, reducing anxiety and stress, and getting enough sleep. A cardiologist may prescribe medication to slow heartbeat, like a beta blocker.

Even if you don't have any other symptoms however, you should have PVCs examined by an expert in cardiology if they occur often. These irregular heartbeats could indicate an issue with the structure of your heart or other health conditions and, over time, when they happen frequently enough, they may weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They simply want to be aware that the fluttering or skippy heartbeats aren't typical.

Diagnosis

PVCs can feel like heartbeats that are fluttering especially if they are frequent and intense. People who get lots of them might feel like they're about to faint. They can also happen with exercising, but most athletes who suffer from them do not have any issues in their heart or health. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses coming from your heart. A cardiologist can also perform an ultrasound echocardiogram to study the heart.

A doctor will usually be able to determine if a patient has PVCs by examining them and taking their medical history. However, sometimes they will only notice them while examining the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitoring systems can assist in detecting PVCs and other arrhythmias, and they might be used when there is a concern of a cardiac condition.

If your cardiologist determines your heart is structurally healthy, reassurance may be all that's needed. If your symptoms are bothersome 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 help reduce the frequency of PVCs. If your symptoms persist or are extreme, talk to your doctor about treatments that could help control them.

Treatment

If PVCs are rare or don't cause symptoms, they don't usually need treatment. If you are frequently affected and frequently, your doctor might want to check for other heart conditions and suggest lifestyle changes or medication. You could also have an intervention to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs The electrical signal that causes your heartbeat starts somewhere other than the sinoatrial node (SA node) in the top right side of your heart. This can cause your heart to feel as if it skips a beating or has extra beats. It's not known what causes these, but they're more common in people who have other heart conditions. PVCs are more likely to occur as you age, and might occur more frequently during exercises.

If a patient is experiencing frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor may also perform an exercise stress test in order to determine if the additional heartbeats are due to physical activity. To determine if there are other causes for the extra beatings the heart catheterization or a cardiac MRI can be performed.

The majority of people who suffer from PVCs do not suffer from any issues and can live a normal lifestyle. They could increase the risk of dangerous heart rhythm disorders particularly if they develop in certain patterns. In certain cases, it means that the heart muscle becomes weaker and is having difficulty pumping blood throughout your body.

Regular exercise and a balanced diet can lower your chances of developing PVCs. Avoid foods high in fat and sodium, and limit your consumption of caffeine and tobacco. You should also try to get enough sleep and manage stress. Certain medications can increase the risk of getting PVCs. So if you take one of these medications it's crucial to follow your doctor's recommendations regarding eating healthy, exercising and taking your medication.

Studies of patients suffering from a high burden of PVCs (that's more than 20% of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require an organ transplant.
