10 Unexpected Pvc Doctor Tips
How a VC Can Affect Your Heart

A lot of people experience 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 located in the upper right part of your heart (the sinoatrial or SA node) typically regulates the heart's rhythm. Electrical signals travel to ventricles, or lower chambers of the heart.

Causes

PVCs occur when the electrical impulse that typically begins your heartbeat at a point known as the sinus node (also called the sinoatrial or SA Node) isn't. The impulse actually starts in the ventricles, which causes an irregular heartbeat. These extra beats, called ventricular tachycardia or fibrillation, may feel like your heart skipped a beat, or it feels like it is fluttering. They may happen rarely and not cause any symptoms, or they can happen often enough to affect your quality of life. If they happen frequently or cause weakness, dizziness or fatigue, your doctor may treat them with medication.

PVCs are generally harmless and do not increase your risk of heart disease. A lot of PVCs, however, can weaken your heart muscle over time. This is especially relevant if they are triggered by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which may lead to symptomatic heart failure.

PVCs can trigger symptoms, such as a sensation of your heart skipping one beat, or even fluttering. You may also feel exhausted. The fluttering could be more evident when you exercise, or consume certain foods or beverages. People who suffer from chronic anxiety or stress can have more PVCs and certain medications such as amiodarone, digoxin, and cocaine may increase the likelihood of developing them.

If you experience occasional PVCs your doctor may recommend lifestyle changes and medications. If they are a frequent occurrence, you may need to stay clear of certain foods and beverages like alcohol and caffeine. You can also lower stress by taking enough rest and working out.

If you have many PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. Electrophysiologists are the ones who perform this procedure. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from recurring in the future. In certain instances, it can increase the risk of developing atrial fibrillation (AFib) which is a condition that can result in stroke. This is rare however it could be life-threatening.

Signs and symptoms

Premature ventricular contractions, also known as PVCs, can make your heart seem to flutter or skip one beat. These extra heartbeats are harmless, but you might need to see your doctor if they are frequent or if you are experiencing symptoms such as dizziness or fatigue.

The electrical signals normally begin in the sinoatrial area, which is located in the upper right part of the heart. They then travel to the lower chambers, or ventricles, that pump blood. The ventricles contract to force blood into the lung. They then return to the center to start the next cycle of pumping. A PVC begins at a different spot in the Purkinje fibres bundle in the bottom left of the heart.

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

Anyone who has had a prior heart attack or suffer from cardiomyopathy -which affects how the heart pumps blood must be aware of their PVCs and talk to a cardiologist about lifestyle changes. This includes avoiding caffeine, alcohol and smoking, reducing anxiety and stress, and getting enough sleep. A cardiologist can prescribe medications to slow heartbeat, for example, beta blockers.

Even if there aren't any other symptoms, you should still get PVCs examined by an expert in cardiology if they occur often. These extra heartbeats can indicate an issue with the structure of your heart or other health conditions and, over time, if they occur often enough, they could weaken the heart muscle. But most people suffering from PVCs don't have any issues. They simply want to be aware that the fluttering and racing heartbeats aren't normal.

Diagnosis

PVCs can feel like heartbeats that are fluttering especially if they are frequent and intense. People who experience them frequently might feel faint. Exercise can trigger them, but most athletes who suffer from them have no heart or health issues. PVCs can be detected on tests such as an electrocardiogram or a Holter monitor. These patches contain sensors that record electrical impulses coming from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.

A doctor may be able to tell whether someone is suffering from PVCs through a medical history and physical exam. Sometimes, however, they may only be able to detect PVCs when they examine a patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They may be used to detect heart disease when there is a reason to be concerned.

If your cardiologist has determined that your heart is structurally healthy, reassurance may be all you need. If your symptoms are bothersome, or cause you to be anxious, avoiding alcohol, caffeine and over-the counter decongestants, and decreasing stress can help. Regular exercise, maintaining a healthy weight, and drinking enough fluids can help to reduce the frequency of PVCs. If the symptoms persist or are extreme, talk to your doctor about medication options to treat the symptoms.


Treatment

If PVCs are rare or don't cause symptoms, they do not usually require treatment. If they are frequent your doctor may need to examine for heart problems or suggest lifestyle modifications. You could also have an operation to rid yourself of them (called radiofrequency catheter ablation).

When you have PVCs The electrical signal that causes your heartbeat starts somewhere outside of the sinoatrial node (SA node) located in the upper right corner of your heart. This could cause it to feel like your heart skips a beat or has extra beats. It's not clear what causes them, but they're more frequent in those with other heart issues. PVCs are more likely to occur as you age, and they may be more frequent during exercise.

A physician should perform an ECG as well as an echocardiogram on a patient who has frequent and painful PVCs to determine if there are structural heart problems. They may also perform an exercise stress test to determine whether the extra beats are a result of physical activity. A heart catheterization or cardiac MRI or nuclear perfusion studies can be done to look for other reasons for the extra beats.

Most people with PVCs don't experience any issues and can live a normal lifestyle. However, they can increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In certain cases, it means the heart muscle gets weaker and is unable to pump blood throughout your body.

Regular exercise and a balanced diet will reduce your chances of developing PVCs. Avoid windows doctor that are high in sodium and fat, and limit your consumption of caffeine and tobacco. It is also important to get enough rest and reduce stress. Certain medications can increase your risk of getting PVCs. If you are taking any of these medicines, 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 suffering from an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to a need for a heart transplant in some patients.
