How a VC Can Affect Your Heart

A lot of people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

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

Causes

PVCs happen when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or 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 known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat, or it feels like it is fluttering. They can happen infrequently and not cause any symptoms, or they can happen often enough to affect your quality of life. If they happen frequently or cause weakness, dizziness, or fatigue, your doctor could treat them with medication.

PVCs are generally harmless and do not increase your risk of heart disease. In time, repeated PVCs can weaken the heart muscle. This is particularly relevant if the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy which can cause heart failure.

The symptoms of PVCs include feeling like your heart beats slower or it flutters. You may feel breathless. The fluttering could be more apparent when you exercise or have certain foods or drinks. People with chronic stress or anxiety can have more PVCs and certain medications like amiodarone digoxin, and cocaine may increase the chance of developing them.

If you are experiencing occasional PVCs your doctor may suggest lifestyle changes and medications. If they are a frequent occurrence, you may need to avoid certain drinks and foods, such as caffeine and alcohol. You can also take steps to reduce your stress levels, and take advantage of plenty of rest and exercise.

If you have a lot of PVCs the doctor might recommend a medical treatment known as radiofrequency catheter ablation, which eliminates the cells that cause PVCs. The procedure is carried out by a specialist, known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms but it doesn't stop them from occurring in the future. In some cases it can increase the risk of developing atrial fibrillation (AFib) which is which can lead to stroke. This isn't common, but it can be life-threatening.

Signs and symptoms

Premature ventricular contracts PVCs, also known as PVCs, can cause your heart to skip or flutter. These extra heartbeats can be harmless, but you may be advised to consult your physician if they are frequent or if you notice symptoms like dizziness, or fatigue.

Normaly, electrical signals begin in the sinoatrial, located in the upper right corner of the heart. They then move to the window doctors lower chambers, also known as ventricles, where blood pumps are located. The ventricles then contract to propel blood into your lungs, and return to the heart and start the next pumping cycle. A PVC starts in a different location, the Purkinje fibres bundle in the left-hand side of the heart.

When PVCs happen and the heart is affected, it may feel as if it's beating faster or slower. If you have just a few episodes but no other symptoms, your doctor will probably not treat you. However, if you have lot of PVCs the doctor may recommend an electrocardiogram, or ECG to determine the heart's rate over the course of 24 hours. He or she may also recommend wearing a Holter monitor that records the heart's rhythm over time, allowing you to see how many PVCs you have.

If you've had a prior heart attack or suffer from cardiomyopathy -- a condition that affects how the heart pumps blood should take their PVCs seriously and speak with an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, managing anxiety and stress, and getting enough rest. A cardiologist may prescribe medications to slow heartbeat, like beta blockers.

Even if you don't experience any other indications however, you should have PVCs checked by a cardiologist if they happen often. These heartbeats that are irregular can indicate an issue with the structure of your heart or other health conditions and, over time, when they are frequent enough, they could weaken the heart muscle. The majority of people with PVCs don't experience any issues. They simply want to know that the fluttering or skipping heartbeats aren't normal.

Diagnosis

PVCs may feel like heartbeats that flutter, especially if they are frequent and intense. People who experience them often may feel weak. Exercise can trigger PVCs, but a lot of athletes who experience these symptoms do not have heart or health issues. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These are sticky patches that have sensors on them to record electrical impulses from your heart. A cardiologist might also use an echocardiogram, which uses ultrasound to study the heart and observe how it's working.

Most of the time, a upvc Doctor near me will be able to tell whether someone has PVCs through a medical history and physical exam. However, sometimes they will only be able to detect them when they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias and could be utilized in the event of any suspicion of cardiac disease.

If your cardiologist finds that your heart's structure is normal, reassurance will be the only remedy required. If your symptoms are causing you discomfort, or cause you to feel anxious, staying away from alcohol, caffeine and over-the counter decongestants, and reducing stress may aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are severe, speak with your physician about possible medication options to treat the symptoms.

Treatment

If PVCs don't cause symptoms or happen rarely, they usually don't need treatment. If you have them often, your doctor may want to check for other heart conditions and recommend lifestyle changes or medicine. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs in your heart the electrical signal that triggers your heartbeat starts somewhere outside of the sinoatrial (SA) node, which is located in the upper right-hand corner of your heart. This can make it feel like your heart skips beats or is beating faster. It's not clear what causes them, but they're more common in people with other heart issues. PVCs can become more frequent as you age, and could be more frequent during exercise.

A physician should perform an ECG along with an echocardiogram on a patient that has frequent and painful PVCs to rule out structural heart diseases. The doctor will also conduct an exercise stress test in order to determine if the increased heartbeats are due to physical activity. A heart catheterization, cardiac MRI or nuclear perfusion study can be conducted to determine other causes of the additional beats.

Most people with PVCs do not experience any issues and can live an ordinary life. But they can increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In certain cases, it means that the heart muscle becomes weaker and has trouble pumping blood through your body.

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

Studies of patients with a high amount of PVCs (that's more than 20 percent of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. Some people may need an organ transplant.
