How a VC Can Affect Your Heart

PVCs are common and may 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 your risk of heart failure.

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

Causes

PVCs occur when the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or the SA node) does not. Instead, the impulse begins in a different part of your heart called the ventricles and triggers a wrongly timed beat. These extra beats are called ventricular tachycardia or ventricular fibrillation. It may feel like the heart beats faster or feels like it is fluttering. They may occur infrequently without causing any symptoms, but they may be frequent enough to affect your quality of life. Your doctor might prescribe medication when they occur frequently or cause dizziness, weakness or fatigue.

In Repair My Windows And Doors , PVCs are harmless and don't increase your risk of developing heart disease or other health problems. Over time, frequent PVCs can weaken the heart muscle. This is especially relevant if they are triggered by a heart disease such as dilated cardiomyopathy arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

The signs of PVCs include feeling like your heart skips a beat or flutters, and you may feel breathless. The fluttering could be more noticeable when you exercise or consume certain drinks or food items. People who suffer from chronic anxiety or stress can have more PVCs and certain drugs like amiodarone digoxin, and cocaine may increase the risk of developing them.


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

If you have a lot of PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. This is done by a specialist, known as an electrophysiologist. The treatment is typically effective in treating PVCs and reducing symptoms, but it does not stop them from returning in the future. In some instances it may increase your risk of atrial fibrillation (AFib), which can cause stroke. It is not common however it could be life-threatening.

Signs and symptoms

Premature ventricular contractures or PVCs may cause your heart to skip or to flutter. These heartbeats that are not normal can be harmless, but you might want to consult your doctor when they occur frequently or if you experience symptoms like dizziness or fatigue.

The electrical signals typically begin in the sinoatrial node, located in the top right-hand side of the heart. These signals descend to the lower chambers (or ventricles) that pump blood. The ventricles expand to force blood into the lungs. They return to the heart's center to start the next cycle of pumping. But a PVC starts in a different location, from the bundle of fibers called the Purkinje fibers in the left-hand side of the heart.

When PVCs occur they can make the heart feel like it is beating faster or slower. If you have only a few episodes, but no other symptoms, the cardiologist probably won't treat you. However, if you have number of PVCs the doctor may recommend an electrocardiogram, or ECG, to measure the heart's rate over 24 hours. The doctor may also suggest wearing a Holter Monitor that records your heartbeat and tracks the number of PVCs.

People who have suffered a heart attack in the past or have cardiomyopathy -- a condition that affects how the heart pumps bloodand should take their PVCs seriously and talk to a cardiologist about lifestyle changes. These include avoiding alcohol, caffeine and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow down the heartbeat.

Even if you don't have any other symptoms however, you should have PVCs checked by an cardiologist if they occur often. These heartbeats that are irregular can point to problems with the structure of your heart or other health issues and, over time when they happen frequently enough, they can weaken the heart muscle. But most people with PVCs don't have any issues. They are interested in knowing if the irregular heartbeats or fluttering is normal.

Diagnosis

PVCs can be felt as fluttering or skipped heartbeats, particularly when they're intense or frequent. Patients who have a lot of them might feel like they're about to faint. They can also occur with exercise, though many athletes who get them don't have any problems with their health or heart. PVCs may show up in tests like an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist can also perform an ultrasound echocardiogram to examine the heart.

Most of the time, a doctor will be able to tell whether the patient has PVCs from a history and physical examination. Sometimes it is possible that they not be aware of PVCs until they examine a patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors can detect PVCs, as well as other arrhythmias. They may be used to detect heart disease if there is any reason to be concerned.

If your cardiologist determines that your heart's structure is normal, reassurance is the only treatment needed. If your symptoms are bothersome or make you feel anxious, staying away from alcohol, caffeine, and over the prescription decongestants, as well as reducing stress may aid. Getting regular exercise, staying at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medications that could help control the symptoms.

Treatment

If PVCs aren't common or don't cause symptoms, they rarely require treatment. If you have them often and frequently, your doctor might want to check for other heart conditions and recommend lifestyle changes or medication. You could also have an operation to rid yourself of them (called radiofrequency catheter ablation).

If you suffer from PVCs in your heart, the electrical signal which creates your heartbeat is located outside of the sinoatrial (SA) node that is located in the upper right-hand 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 them, but they're more common in people with other heart problems. PVCs can become more frequent as you age, and they may be more frequent during exercising.

If a patient is experiencing frequent and painful PVCs doctors should perform an ECG and an echocardiogram to determine if there is a structural heart problem. They will probably also do an exercise stress test to determine if the extra beats are due to physical activity. To determine whether there are other reasons for the extra beats an invasive heart catheterization or a cardiac MRI can be performed.

Most people with PVCs don't experience any problems and can enjoy an ordinary life. They could increase your risk for dangerous heart rhythm disorders, especially if they occur in certain patterns. In some cases, that means that your heart muscle gets weaker and is unable to pump blood through your body.

Regular exercise and a healthy diet can lower the risk of developing PVCs. Avoid foods high in sodium and fat, and limit your intake of caffeine and tobacco. You should also try to sleep enough and reduce stress. Certain medicines can also increase your risk of getting PVCs. So if you take one of these medications it's crucial to follow your doctor's instructions about a healthy diet, exercise and taking your medication.

Studies of patients who had a high burden of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
