How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a variety of people without causing any problems. If they are frequent, PVCs may weaken your heart and increase your risk for heart failure.

The rhythm of your heart is controlled by a group of fibers that are located in the upper right-hand corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals travel from this node to the lower heart chambers, or ventricles.

Causes

PVCs happen when the electrical impulse that usually starts your heartbeat in a region known as the sinus node (also known as the sinoatrial node or SA node) isn't. Instead, the impulse is generated in another area of your heart, the ventricles, and causes an untimed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or feels like it is fluttering. They can happen infrequently and not cause any symptoms, but they may also happen frequently enough to affect your standard of life. If they happen frequently or cause weakness, dizziness or fatigue, your glass doctor might treat them with medication.

PVCs are generally harmless and don't increase your risk of developing heart disease. In time, frequent PVCs can weaken the heart muscle. This is particularly when the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure.

The signs of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering can be more apparent when you exercise or have certain drinks or foods. People who suffer from chronic stress or anxiety can have more PVCs and certain medications such as amiodarone, digoxin, and cocaine can increase the risk of developing them.

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

If you're experiencing many PVCs, he may recommend a medical treatment known as radiofrequency catheter ablation, which eliminates the cells that cause PVCs. Electrophysiologists are the ones who execute this procedure. The treatment is usually effective in treating PVCs, reducing symptoms but does not prevent them from recurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib) which is an illness that can cause stroke. It's not common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to skip or flutter the beat. These heartbeats can be harmless, but it is important to consult your physician when you experience frequent episodes or symptoms like dizziness or weakness.

The electrical signals normally begin in the sinoatrial region, which is in the upper right-hand corner of the heart. They then move to the lower chambers, or ventricles, that pump blood. The ventricles then contract to propel the blood into the lungs, and return to the heart to begin the next cycle of pumping. But a PVC begins in a different location and is located in the bundle of fibers called the Purkinje fibers, in the bottom left portion of the heart.

When PVCs occur, they can make the heart pound or feel like it skipped a beat. If you have only a few episodes, and no other symptoms are present the cardiologist will likely not prescribe treatment. But if you have a number of PVCs and you have other symptoms, your doctor might recommend an electrocardiogram, or ECG, to measure your heartbeat over the course of 24 hours. The doctor may also recommend wearing a Holter monitor that records the heart's rhythm over time to see the number of PVCs you have.

People who have suffered an earlier heart attack or cardiomyopathy, a condition which affects the method by which the heart pumps blood - should take their PVCs very seriously and consult a cardiologist regarding lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, and getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.

Even if there aren't any other indications, you should still get PVCs examined by a cardiologist if they happen frequently. These irregular heartbeats could indicate a problem in the structure of your heart or lungs, and if they occur often enough, it could weaken the heart muscle. The majority of people with PVCs do not experience any issues. They would like to know if irregular heartbeats or fluttering is normal.

Diagnosis

PVCs might appear to be fluttering or skip heartbeats, particularly when they are frequent or intense. People who get lots of them might feel like they're about to faint. Exercise can trigger them, but many athletes who suffer from them do not have heart or health issues. PVCs may show up in tests like an electrocardiogram or Holter monitor. These use sticky patches with sensors on them to record electrical impulses coming from your heart. A cardiologist may also use an ultrasound echocardiogram to study the heart.

A doctor will usually be able to determine if a patient has PVCs by looking at them and taking a medical history. Sometimes however, they might only be able to detect PVCs when they examine the patient for another reason such as following an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to identify cardiac problems in the event of any concerns.

If your cardiologist concludes that your heart is structurally normal, reassurance is the only remedy required. However, if your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine and other decongestants and reducing stress may aid. Regular exercise and maintaining a healthy weight and drinking enough fluids can all help to reduce the frequency of PVCs. If the symptoms persist or are severe, speak to your doctor about possible medication options to treat these symptoms.

Treatment

If PVCs are rare or don't cause symptoms, they do not usually need treatment. If you are frequently affected, your doctor may want to look for other heart conditions and suggest lifestyle changes or medication. You may also undergo a procedure (called radiofrequency cathode ablation) to eliminate them.

If you suffer from PVCs, the electrical signal that causes your heartbeat begins somewhere different than the sinoatrial nerve (SA node) in the top right side of your heart. This could cause your heart to feel as if it skips beats or has additional beats. PVCs are more frequent among those who suffer from heart issues however, it's not clear what causes them. PVCs can become more frequent as you age, and might occur more frequently during exercising.

If a patient experiences frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also perform an exercise stress test to determine if the extra heartbeats are related to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be performed to find other causes for the extra beats.

The majority of people who suffer from PVCs don't experience any problems and can enjoy an ordinary life. But they can increase your risk of having dangerous heart rhythm problems especially if you are suffering from certain patterns of them. In certain cases, it means that the heart muscle becomes weaker and has trouble pumping blood throughout your body.

A healthy, regular diet and plenty of exercise can reduce the risk of developing PVCs. Avoid foods that are high in fat and sodium and limit your consumption of tobacco and caffeine. You should also try to sleep enough and manage stress. Certain medicines can also increase your risk of PVCs. So if you take one of these medicines, it's important to follow the doctor's advice about eating well, exercising and taking your medication.

In studies of patients with Pvc Doctor burdens that are high (more than 20% of the total heartbeats), a higher rate arrhythmia-induced cardiac myopathy was found. This can lead to the need for a heart transplant in a few individuals.
