How a VC Can Affect Your Heart

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

The rhythm of your heart is controlled by a bundle of fibers that are located in the upper right-hand part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals are transmitted to the lower heart chambers or ventricles.

Causes

PVCs occur when the electrical impulse that usually starts your heartbeat at a point called the sinus node (also called 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 are called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beat or feels fluttering. They may happen rarely and not cause any symptoms, or they can happen often enough to impact your daily life. Your doctor may prescribe medicine if they are frequent or cause weakness, dizziness or fatigue.

PVCs are generally harmless and don't increase your risk of heart disease. Regular PVCs however, may weaken the heart muscle over time. This is especially true if the PVCs result from conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that can lead to heart failure.

The signs of PVCs include a feeling that your heart beats slower or flutters, and you may feel exhausted. The fluttering could be more apparent when you exercise or have certain drinks or foods. People with chronic anxiety or stress can have more PVCs, and some drugs like amiodarone digoxin, and cocaine can increase the likelihood of developing them.

If you have occasional PVCs Your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor might recommend avoiding certain foods and drinks like caffeine and alcohol. You can also reduce your stress by having enough sleep and exercising.

If you have a lot of PVCs the doctor might suggest a medical treatment called radiofrequency catheter ablation. It destroys cells that cause PVCs. Electrophysiologists are the ones who carry out this procedure. The treatment is usually successful in treating PVCs, reducing symptoms but does not prevent them from returning in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib) which can cause a stroke. It is not common, but it could be life-threatening.

Signs and symptoms

Premature ventricular contractions or PVCs, can cause your heart seem to flutter or skip one beat. These extra heartbeats are harmless, but you may want to consult your doctor when they occur frequently or if you notice symptoms like dizziness, or fatigue.

Normally, electrical signals begin in the sinoatrial node located in the top right side of the heart. These signals descend to the lower chambers (or ventricles) that pump blood. The ventricles then contract to pump blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC begins in a different place, from the bundle of fibers called the Purkinje fibers, in the lower left part of the heart.





When PVCs occur they can make the heart feel like it is racing or pounding. If you have just a few episodes but no other symptoms, the cardiologist probably won't treat you. If you've got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to measure the heartbeat over the course of 24 hours. The doctor may also suggest wearing a Holter Monitor, which records your heart rhythm and counts the number of PVCs.

People who have had a prior heart attack or have cardiomyopathy -an illness that alters the way the heart pumps blood -and should take their PVCs seriously and consult a cardiologist about changes to their lifestyle. These include abstaining from caffeine, alcohol, and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist may also prescribe medication to slow the heartbeat for example, a beta blocker.

Even if you don't experience any other indications it is still recommended to have PVCs examined by an expert in cardiology if they occur frequently. These irregular heartbeats could be a sign of a problem with the structure of your heart or lungs, and if they occur frequently enough, they can weaken the heart muscle. But the majority of people with PVCs don't experience any problems. They just want to be aware that the fluttering and skipping heartbeats aren't normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, particularly when they're frequent or intense. Patients who have a lot of them might feel like they're going to faint. Exercise can trigger them, but many athletes who suffer from them do not have heart or health problems. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.

A doctor may be able to tell whether the patient is suffering from PVCs through a medical history and physical exam. Sometimes however, they might only be able to detect PVCs when they examine the patient for another reason, such as after an accident or surgery. double glazing doctor monitoring systems can also help detect 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 will be the only treatment needed. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine and over-the prescription decongestants, as well as decreasing stress can aid. Regular exercise, being at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If your symptoms continue or are severe, speak to your doctor about possible medications that can control them.

Treatment

If PVCs are rare or do not cause symptoms, they don't usually require treatment. If they occur frequently, your doctor might want to check for heart problems or suggest lifestyle changes. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate them.

If you have PVCs in your heart, the electrical signal which triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node, which is located in the upper right corner of your heart. This can make it feel like your heart skips a beat or is beating faster. 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 they could be more frequent during exercises.

If a patient is experiencing frequent and painful PVCs doctors is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. windows doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are caused by physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be conducted to determine other causes for the extra beats.

The majority of people with PVCs are not affected and live the normal life. However, they can increase your risk of having dangerous heart rhythm issues particularly if you have certain patterns of them. In some cases, that means that your heart muscle gets weaker and is unable to pump blood through your body.

A regular, healthy diet and regular exercise can help reduce your chances of developing PVCs. Avoid foods that are high in fat and sodium, and limit your consumption of caffeine and tobacco. It is also important to sleep enough and manage stress. Certain medications can increase the risk of developing PVCs. If you take any of these medicines it is essential to follow the advice of your doctor regarding healthy eating and exercising as well as taking your medication.

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