How a VC Can Affect Your Heart
PVCs are commonplace and can be experienced by a wide range of people without causing any 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) usually controls your heart rhythm. Electrical signals are transmitted to the lower heart chambers or ventricles.
Causes
PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) is not initiated. Instead, the impulse begins in another area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, could feel as if your heart skipped a beat or feels like it's fluttering. They may happen rarely and not cause any symptoms, or they can occur frequently enough to affect your daily life. Your doctor may prescribe medicine when they occur frequently or cause dizziness, weakness or fatigue.
PVCs are generally safe and do not increase your risk of developing heart disease. A lot of PVCs however, could weaken your heart muscle over time. This is especially true if the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can cause heart failure.
window doctor near me Repair My Windows And Doors of PVCs include feeling like your heart beats faster or flutters, and you may feel breathless. The fluttering may be more apparent when you exercise or have certain foods or drinks. People who experience chronic anxiety or stress may have more PVCs, and some medications such as amiodarone, digoxin and cocaine can increase the risk of developing them.
If you are experiencing occasional PVCs Your doctor might suggest lifestyle changes and medications. If they are a regular occurrence, you may have to stay clear of certain drinks and foods, such as alcohol and caffeine. You can also lower your stress 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, which eliminates the cells that are responsible for them. Electrophysiologists are the ones who perform this procedure. The treatment is usually successful in treating PVCs and reducing symptoms, but it does not stop them from returning in the future. In some cases, it can increase your risk of atrial fibrillation (AFib), which can cause a stroke. This is rare but can be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, can cause your heart appear to skip or flutter a beat. These extra heartbeats can be harmless, but you may be advised to consult your physician when they occur frequently or if you are experiencing 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, and travel down to the lower chambers (or ventricles) which pump blood. The ventricles contract to push the blood into the lung. They return to the center to begin the next cycle of pumping. However, a PVC begins in a different location and is located in the bundle of fibers, known as the Purkinje fibers in the lower left part of the heart.
When PVCs happen and the heart is affected, it may appear to be racing or pounding. If you experience only one or two episodes, and there are no other symptoms, your cardiologist will probably not be able to treat you. If you have many PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter monitor that will track the heart's rhythm over time to determine how many PVCs you have.
People who have suffered a previous heart attack or cardiomyopathy, an illness that affects method by which the heart pumps blood - must take their PVCs seriously and consult a cardiologist regarding lifestyle modifications. This includes avoiding caffeine, alcohol and smoking, reducing anxiety and stress and getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.
Even if you don't experience any other signs, you should still get PVCs checked by an expert in cardiology if they occur often. These heartbeats that are irregular could be a sign of a problem with the structure of your heart or lungs and if they happen often enough, it could weaken the heart muscle. However, most people suffering from PVCs don't have any issues. They would like to know if fluttering heartbeats or skipping heartbeats is normal.
Diagnosis
PVCs may feel like heartbeats that are fluttering particularly if they're frequent and intense. Patients who have a lot of them might feel like they're about to faint. Exercise can trigger PVCs, but a lot of athletes who experience them do not have heart or health problems. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram for examining 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 may only notice PVCs when examining patients for a different reason, like following an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and can be used in the event of any suspicion of a cardiac condition.
If your cardiologist concludes that your heart is structurally normal, reassurance is the only remedy required. If your symptoms are bothersome, or cause you to feel anxious, avoiding alcohol, caffeine, and over the prescription decongestants, as well as decreasing stress can help. Regular exercise, being at a healthy weight, and drinking enough fluids can decrease the likelihood of PVCs. If you are experiencing symptoms that are persistent or extreme, consult your doctor about medication that could be able to reduce them.
Treatment
If PVCs do not cause any symptoms or are not frequent, they usually don't need treatment. If they are frequent your doctor may be able to look for heart conditions or recommend lifestyle changes. You could also have an operation (called radiofrequency cathode ablation) to eliminate of them.
If you have PVCs in your heart, the electrical signal which creates your heartbeat is located outside of the sinoatrial (SA) node located in the upper right corner of your heart. This can cause your heart to feel like it skips a beating or has extra beats. It's unclear what causes these symptoms, but they're frequent in those with other heart conditions. PVCs may increase in frequency as you age, and they might occur more frequently during exercises.
A doctor should conduct an ECG and an echocardiogram on a patient who has frequent and painful PVCs to rule out structural heart diseases. The doctor will also likely perform an exercise stress test in order to determine if the extra heartbeats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be done to look for other causes of the extra beats.
The majority of people who suffer from PVCs are not affected and can lead the normal life. However, they can increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some cases this means that the heart muscle gets weaker and it is more difficult to pump blood throughout the body.
A regular, healthy diet and a lot of exercise can reduce your risk of developing PVCs. Avoid foods that are high in sodium and fat as well as limit caffeine and tobacco. Sleep and stress are equally crucial. Certain medications can increase your risk of getting PVCs. If you are taking any of these medications it is essential to follow your doctor's recommendations regarding eating a healthy diet, exercising, and taking your medication.
In studies of patients with PVC burdens that are excessive (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 people.
