How a VC Can Affect Your Heart

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

A bundle of fibers in the upper right-hand corner of your heart (the sinoatrial node, also known as SA) typically controls the heart's rhythm. Electrical signals are transmitted to the lower heart chambers or ventricles.

Causes

PVCs occur when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different area of your heart--the ventricles--and causes a wrongly timed beat. These extra beats, also called ventricular tachycardia or ventricular fibrillation, may feel like your heart skipped a beat, or it feels like it is like it's fluttering. window doctors near me can happen infrequently and not cause any symptoms, but they can occur frequently enough to impact your quality of living. Your doctor might prescribe medication when they occur frequently or cause weakness, dizziness or fatigue.

PVCs are generally harmless and do not increase your risk of developing heart disease. Over time, repeated PVCs can weaken the heart muscle. This is especially true if the PVCs result from an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which could lead to heart failure.

PVCs can trigger symptoms like a feeling of your heart skipping a beat, or fluttering. It is also possible to feel exhausted. The fluttering can be more evident when you exercise, or eat or drink certain beverages or foods. PVCs are more prevalent in people with chronic anxiety or stress. Certain medications, like digoxin, amiodarone, and cocaine, may increase the risk of developing PVCs.

If you experience occasional PVCs your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your physician may recommend avoiding certain foods and drinks like caffeine and alcohol. You can also take steps to lessen your stress levels, and make sure you get enough sleep and exercise.





If you have many PVCs, your doctor may suggest a medical procedure called radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. This is done by a specialist known as an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms however, it doesn't prevent them from occurring in the future. In some cases it can increase the risk of having atrial fibrillation (AFib), an illness that can lead to stroke. This isn't common, but it can be life-threatening.

Symptoms

Premature ventricular contractions PVCs, also known as PVCs, can cause your heart to skip or be fluttering. These heartbeats can be harmless, but you should consult your physician if you have frequent episodes or signs like dizziness or weakness.

The normal electrical signals start in the sinoatrial, located in the upper right-hand part of the heart. They then move to the lower chambers, or ventricles, which pump blood. The ventricles contract to pump blood into the lungs. They return to the heart's 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 occur, they cause the heart beat or feel as if it skipped one beat. If you have a few episodes and no other symptoms, your cardiologist probably won't treat you. If you've got a number of PVCs the doctor may recommend an electrocardiogram, also known as an ECG to determine your heartbeat over 24 hours. The doctor may also suggest wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

If you've had a previous heart attack or suffer from cardiomyopathy -which affects the way that the heart pumps blood- should take their PVCs seriously and speak with a cardiologist about lifestyle changes. Those include abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and getting enough sleep. A cardiologist can prescribe beta blockers to slow down the heartbeat.

If you experience frequent PVCs even if do not have any other symptoms you should see a cardiologist. These heartbeats that are irregular can indicate problems with the structure of your heart or other health conditions and, over time, when they happen frequently enough, they can weaken the heart muscle. Most people with PVCs don't experience any issues. They simply want to be aware that the fluttering or racing heartbeats aren't normal.

Diagnosis

PVCs can be akin to heartbeats that are fluttering, particularly if they're frequent and intense. People who get lots of them may feel they're about to faint. Exercise can cause them, but many athletes who suffer from these symptoms do not have heart or health problems. PVCs can show up in tests like an electrocardiogram or a Holter monitor. They have sensors that record electrical impulses from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to look at the heart and determine how it's functioning.

Most of the time, a doctor will be able to determine if the patient has PVCs through a medical history and physical examination. Sometimes, they may not be aware of them until they examine the patient for other reasons, such as after an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They are able to detect heart disease when there is a concern.

If your cardiologist has determined that your heart is structurally healthy, reassurance could be all that's needed. If your symptoms are troubling or make you feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may aid. Regular exercise, being at a healthy weight and drinking enough water can also decrease the likelihood of PVCs. If your symptoms continue or are severe, speak to your doctor about medication options to treat the symptoms.

Treatment

If PVCs are rare or do not cause symptoms, they don't usually need treatment. If they occur frequently your doctor may be able to look for heart conditions or recommend lifestyle adjustments. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate 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 that is located in the upper right-hand corner of your heart. This could cause your heart to feel as if it skips a beating or has additional beats. PVCs are more frequent among those with heart problems however, it's not clear the reason behind them. PVCs are more likely to occur as you age, and they might occur more frequently during exercise.

A doctor should perform an ECG as well as an echocardiogram on a patient that suffers from frequent and painful PVCs to identify structural heart conditions. They may also perform an exercise stress test to see if the extra beats are a result of physical activity. A heart catheterization, cardiac MRI or nuclear perfusion studies can be performed to find other causes of the additional beats.

Most people who suffer from PVCs do not suffer from any complications and can lead a normal lifestyle. They may increase the risk of dangerous heart rhythm disorders, especially if they occur in certain patterns. In some cases, that means that your heart muscle gets weaker and is having difficulty pumping blood through your body.

A regular, healthy diet and a lot of exercise can help reduce your chances of developing PVCs. You should avoid foods that are high in sodium and fat and limit caffeine and tobacco. You should also try to get enough sleep and reduce stress. Certain medications can increase your risk for PVCs. If you are taking any of these medicines, it is important that you follow your doctor's advice regarding eating a healthy diet exercising, as well as taking your medication.

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