How a VC Can Affect Your Heart

A lot of people experience occasional PVCs with no problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.

A bundle of fibers located in the top right portion of your heart (the sinoatrial, or SA, node) typically controls the heart's rhythm. Electrical signals travel to the ventricles or lower chambers of your heart.

Causes

PVCs occur when the electrical impulse that normally initiates your heartbeat in a region called the sinus node (also known as the sinoatrial or SA Node) does not. Instead, the impulse is generated in another area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat, or it feels like it is like it's fluttering. They may happen rarely and not cause any symptoms, or they may occur frequently enough to interfere with your quality of life. If they happen frequently or cause weakness, dizziness or fatigue, your doctor could treat them with medicine.

For most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. Regular PVCs however, could weaken your heart muscle over time. This is especially the case if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.

PVCs can cause symptoms like a feeling of your heart racing an beat, or fluttering. You might also feel breathless. The fluttering can be more evident when you exercise or have certain drinks or food items. PVCs are more common in people with chronic stress or anxiety. Some medications, such as digoxin, amiodarone or cocaine, may increase the risk.

If you experience occasional PVCs Your doctor might suggest lifestyle changes and medications. If they are a frequent occurrence, you may need to avoid certain foods and beverages like alcohol and caffeine. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise.

If you have a lot of PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation. This destroys the cells that are responsible for PVCs. Electrophysiologists are the ones who carry out this procedure. It is generally effective in treating PVCs and reducing symptoms however, it doesn't prevent them from occurring in the future. In certain cases, it can increase your risk of having atrial fibrillation (AFib) which could cause stroke. This is rare, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, can cause your heart appear to skip or flutter the beat. These heartbeats that are not normal can be harmless, but you may be advised to consult your physician in the event of frequent heartbeats or if you notice symptoms like dizziness or fatigue.





The electrical signals typically begin in the sinoatrial node which is in the top right-hand side of the heart. They travel down to the lower chambers (or ventricles) that pump blood. The ventricles contract to pump blood into the lung. They then return to the center to begin the next cycle of pumping. A PVC starts in a different location, the Purkinje fibres bundle in the left side of the heart.

When PVCs happen and the heart is affected, it may feel as if it's beating faster or slower. If you experience only a few episodes, and there are no other symptoms the cardiologist will likely not be able to treat you. If you've got a lot of PVCs, your doctor may suggest you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. They may also suggest wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.

Anyone who has had a prior heart attack or have cardiomyopathy -which affects how the heart pumps blood must be aware of their PVCs and consult an expert in cardiology about lifestyle changes. window doctor near me includes cutting down on caffeine, alcohol and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medication to slow heartbeat, like beta blockers.

Even if there aren't any other symptoms it is still recommended to have PVCs examined by a cardiologist if they happen frequently. These heartbeats that are irregular can indicate a problem with the structure of your heart or to other health conditions and, over time when they are frequent enough, they could weaken the heart muscle. But most people suffering from PVCs don't have any issues. They just want to know that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them often might feel faint. Exercise can trigger them, but many athletes who suffer from them do not have heart or health issues. PVCs may show up on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors that record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

Most of the time, a doctor will be able to determine if the patient is suffering from PVCs through a medical history and physical examination. Sometimes, they may only notice them while examining the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and can be used when there is a concern of a cardiac condition.

If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. If your symptoms are causing you discomfort or cause you to be anxious, avoiding alcohol, caffeine, and over the counter decongestants, and decreasing stress can help. Getting regular exercise, staying at a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are severe, talk with your physician about possible treatments that could help control them.

Treatment

If PVCs don't cause symptoms or occur rarely, they usually don't need treatment. If you experience them frequently or frequently, your doctor may wish to look for any other heart problems and recommend lifestyle changes or medication. You might also get an intervention to get rid of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. It can feel like your heart skips a beat or is beating faster. It's not clear what causes them, but they're more common in people with other heart problems. PVCs can increase in frequency as we age and can occur more frequently during exercise.

A physician should perform an ECG and an echocardiogram for a patient who has frequent and painful PVCs to determine if there are structural heart problems. They will probably also do an exercise stress test to see whether the additional beats are caused by physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study could be conducted to determine other causes for the extra beats.

Most people who suffer from PVCs have no complications and can live a normal life. They may increase the risk of heart rhythm disorders that can be dangerous particularly if they develop in certain patterns. In some instances, this means that the heart muscle becomes weaker and is having difficulty pumping blood through your body.

A healthy, regular diet and a lot of exercise can reduce the risk of developing PVCs. Avoid foods high in fat and sodium and limit your consumption of caffeine and tobacco. Sleep and stress are also important. Certain medications can increase the risk of developing PVCs. If you are taking one of these medicines it's crucial to follow your doctor's recommendations about eating well, exercising and taking your medication.

In studies of patients suffering from PVC burdens that are excessive (more than 20% of heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. This can result in the need for a transplant in certain individuals.
