How a VC Can Affect Your Heart

PVCs are common and can be experienced by a wide range of people without causing any issues. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.

The rhythm of your heart is controlled by a bundle of nerve fibers situated in the upper right-hand part of your heart. This is called the sinoatrial node or SA. Electrical signals travel to the ventricles, or lower chambers of the heart.

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 or SA node) isn't. Instead, the impulse begins in another area of your heart--the ventricles--and causes a mistimed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, could feel as if your heart skipped a beat or is like it's fluttering. They can happen infrequently, causing no symptoms, but they can also happen frequently enough to affect your quality of living. Your doctor may prescribe medication if they are frequent or cause weakness, dizziness or fatigue.

For most people, PVCs are harmless and do not increase the risk of developing heart disease or other health problems. In time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart-related condition such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.

The signs of PVCs include feeling like your heart beats faster or it flutters. You may feel breathless. The fluttering may be more evident when you exercise or consume certain foods or beverages. People who suffer from chronic anxiety or stress may have more PVCs, and some medications like amiodarone digoxin and cocaine can increase the risk of developing them.

If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medication. If they are a regular occurrence, you may have to avoid some drinks and foods, such as caffeine and alcohol. You can also lower stress by getting enough sleep and working out.

If you've got a lot of PVCs, your doctor may suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells that are responsible for them. Electrophysiologists are the ones who execute this procedure. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from becoming recurring in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib) which is which can result in stroke. This is rare but it could be life-threatening.

Signs and symptoms

Premature ventricular contracts or PVCs may cause your heart to skip or be fluttering. These extra heartbeats are harmless, however you might be advised to consult your physician if they are frequent or if you are experiencing symptoms like dizziness or fatigue.


Normaly, electrical signals begin in the sinoatrial region, which is in the upper right-hand part of the heart. They then travel to the lower chambers, or ventricles, where blood pumps are located. The ventricles expand to push the blood into the lung. They return to the center to start 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 left-hand side of the heart.

When PVCs occur, the heart may feel like it is racing or pounding. If you experience only a few episodes, and no other symptoms are present your cardiologist may not treat you. If you have many PVCs and your doctor might recommend that you undergo an electrocardiogram (ECG) to determine the heartbeat for 24 hours. They may also recommend wearing a Holter monitor that will track your heartbeat over time to see how many PVCs you have.

Anyone who has suffered a heart attack in the past or suffer from cardiomyopathy -which affects how the heart pumps blood -- should be aware of their PVCs and consult a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you are experiencing frequent PVCs even if do not have other signs, you should see an expert in cardiology. These irregular heartbeats could point to a problem with the structure of your heart or other health conditions and, over time, when they happen frequently enough, they can weaken the heart muscle. However, most people suffering from PVCs don't experience any problems. They want to know if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering particularly if they're frequent and intense. Patients who have a lot of them may feel they're about to faint. Exercise can trigger PVCs, but a lot of athletes who suffer from them have no heart or health problems. PVCs may show up on tests such as an electrocardiogram or a Holter monitor. They use sticky patches with sensors that record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to look at the heart and observe how it's functioning.

A doctor can often tell the presence of PVCs by looking at them and taking a medical history. Sometimes, they may not be aware of them until they examine the patient for different reasons, like after a surgery or accident. Ambulatory ECG monitors are able to detect PVCs as well as other arrhythmias. They are able to detect cardiac disease in the event of any reason to be concerned.

If your cardiologist concludes that your heart's structure is normal, reassurance is the only treatment required. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine, and over the drug decongestants and reducing stress may help. Regular exercise, being at a healthy weight, and drinking enough water can help reduce the frequency of PVCs. If your symptoms are persistent or extreme, consult your doctor about medications that may be able to manage them.

If PVCs aren't common or don't cause symptoms, they don't usually need treatment. If they happen frequently, your doctor might need to examine for heart problems or suggest lifestyle changes. You could also undergo a procedure (called radiofrequency cathode ablation) to get rid them.

If you suffer from PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere other than at the sinoatrial (SA) node, which is located in the upper right corner of your heart. This could cause your heart to feel like it skips a beating or has extra beats. window doctor near me what causes them, but they're more common in people with other heart conditions. PVCs are more likely to occur as you age, and could be more frequent during exercises.

A doctor should perform an ECG along with an echocardiogram on a patient that has frequent and painful PVCs to determine if there are structural heart problems. They will probably also do an exercise stress test to determine whether the extra beats are a result of physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other reasons for the increased beats.

The majority of people who suffer from PVCs do not suffer from any problems and can enjoy a normal lifestyle. But they can increase your risk of having dangerous heart rhythm problems particularly if you have certain patterns of them. In certain cases, it means that your heart muscle gets weaker and is unable to pump blood throughout your body.

Regular exercise and a healthy diet can reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of caffeine and tobacco. Sleep and stress are equally important. Certain medications can increase the risk of developing PVCs. If you're taking one of these drugs, it's important to follow the doctor's advice regarding eating healthy, exercising and taking your medication.

In studies of patients with PVC burdens that are high (more than 20% of the total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. This can lead to the need for a heart transplant in some patients.
