How a VC Can Affect Your Heart

PVCs are commonplace and can be experienced by a wide range of people without causing any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase your risk of heart failure.

The heart's rhythm is controlled by a group of fibers that are located in the upper right corner of your heart. This is called the sinoatrial nerve, or SA. Electrical signals are transmitted to the ventricles, or lower chambers of the heart.

Causes

PVCs happen when the electrical impulse which normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. The impulse actually starts in the ventricles, causing a mistimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beating or feels fluttering. They can occur rarely, causing no symptoms, but they may be frequent enough to affect your standard of living. If they occur frequently or cause dizziness, weakness, or fatigue, your doctor could treat them with medicine.

PVCs are generally safe and do not increase your risk of developing heart disease. Regular PVCs however, may weaken your heart muscle over time. This is particularly relevant if they are triggered by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy which can lead to symptomatic heart failure.

PVCs can cause symptoms such as a feeling of your heart racing a beat, or the feeling of your heart fluttering. It is also possible to feel exhausted. The fluttering could be more noticeable if you exercise, or eat or drink certain foods or beverages. PVCs are more common in those suffering from chronic stress or anxiety. Some drugs, like digoxin, amiodarone or cocaine, may increase the risk of developing PVCs.

If you are experiencing occasional PVCs, your doctor may recommend lifestyle changes and medicines. If you experience frequent PVCs, your doctor might recommend that you avoid certain foods and drinks like caffeine and alcohol. You can also lessen your stress by taking enough rest and exercising.

If you have many PVCs Your upvc window doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure destroys the cells that cause them. This procedure is performed by a specialist, known as an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms, however it does not stop them from recurring in the future. In certain instances, it can increase the risk of having atrial fibrillation (AFib) which is which can result in stroke. This is rare but it could be life-threatening.

Symptoms

Premature ventricular contractions, also known as PVCs, can make your heart appear to skip or flutter one beat. These extra heartbeats are usually harmless, but it is important to talk to your doctor when you experience frequent episodes or signs like dizziness or weakness.

Normaly, electrical signals begin in the sinoatrial, located in the upper right-hand corner of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles contract to force blood into the lung. They return to the center to begin the next cycle of pumping. A pvc doctor (http://englishclub-plus.ru/user/hockeypowder79) starts in a different place, the Purkinje fibres bundle in the left side of the heart.

When PVCs occur, they can make the heart beat faster or feel as if it skipped the beat. If you've experienced just a few episodes but no other symptoms, the doctor probably won't be able to treat you. If you've got a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. The doctor may also recommend wearing a Holter Monitor that records the heart's rhythm and count the number of PVCs.

People who have suffered a heart attack in the past or have cardiomyopathy -- a condition that alters the way the heart pumps blood must be aware of their PVCs and consult an expert in cardiology about lifestyle changes. This includes abstaining from alcohol, caffeine and smoking, reducing stress and anxiety and getting enough sleep. A cardiologist might also prescribe medication to slow heartbeat, such as beta blockers.

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 extra heartbeats can be a sign of problems with the structure of your heart or other health conditions and, over time, when they happen frequently enough, they may weaken the heart muscle. Most people with PVCs don't experience any problems. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.

Diagnosis

PVCs may be felt as fluttering or skipped heartbeats, especially 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 experience them do not have heart or health problems. PVCs can show up on tests such as an electrocardiogram or a Holter monitor. They use sticky patches with sensors that record electrical signals from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to study the heart and determine how it's working.

A doctor is often able to tell the presence of PVCs by examining them and taking their medical history. Sometimes it is possible that they only be able to detect PVCs when they examine the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They can be used to detect cardiac disease if there is any reason to be concerned.

If your cardiologist finds that your heart's structure is normal, reassurance is the only remedy required. If your symptoms are causing discomfort or make you feel anxious, staying away from caffeine, alcohol and over-the-counter decongestants and reducing stress may aid. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can also help reduce the frequency of PVCs. If your symptoms are persistent or severe, talk to your physician about the medications that may be able to manage them.

Treatment

If PVCs do not cause any symptoms or occur rarely they aren't usually in need of treatment. If they are frequent your doctor may be able to look for heart problems or suggest lifestyle modifications. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).

If you have PVCs the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) in the top right corner of your heart. This can make it feel like your heart skips beats or has extra beats. PVCs are more frequent among those suffering from heart disease, but it's not known the reason behind them. PVCs may increase in frequency as you age, and they could be more frequent during exercise.

A doctor should perform an ECG as well as an echocardiogram on a patient who has frequent and painful PVCs to identify structural heart conditions. The doctor will also conduct an exercise stress test in order to determine if the increased heartbeats are due to physical exercise. A heart catheterization or cardiac MRI or nuclear perfusion studies can be performed to find other causes for the extra beats.

Most people with PVCs are not affected and can lead a normal life. However, they can increase the risk of developing dangerous heart rhythm issues particularly if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and is unable to pump blood throughout the body.

Regular exercise and a healthy diet can lower your risk of developing PVCs. You should avoid foods that are high in fat and sodium as well as reduce your intake of caffeine and tobacco. It is also important to sleep enough and reduce stress. Certain medications can increase the risk of developing PVCs. If you are taking any of these medications it is crucial to follow the advice of your doctor regarding healthy eating exercising, as well as taking your medication.

Studies of patients who had 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. This can lead to the need for a heart transplant in some people.
