10 Things That Everyone Is Misinformed About Pvc Doctor > 자유게시판

How a VC Can Affect Your Heart

PVCs are common and may be experienced by a wide range of people without causing any problems. If they occur regularly, PVCs can weaken your heart muscle and increase your risk of heart failure.

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

Causes

PVCs happen when the electrical impulse that normally starts your heartbeat in a region known as the sinus node (also called the sinoatrial or SA Node) doesn't. The impulse actually begins in the ventricles, which causes an untimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. It could feel as if the heart skipped a beat or feels like it is fluttering. They can happen infrequently, causing no symptoms, but they could also happen frequently enough to affect your standard of living. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor may treat them with medicine.

In most people, PVCs are harmless and don't increase your risk of developing heart disease or other health issues. Frequent PVCs however, could weaken the heart muscle over time. This is especially true if the PVCs are triggered by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can cause heart failure.

The symptoms of PVCs include a feeling that your heart skips a beat or is fluttering, and you feel breathless. The fluttering may be more noticeable when you exercise or eat or drink certain beverages or foods. PVCs are more prevalent in people with chronic stress or anxiety. Some drugs, like digoxin, amiodarone and cocaine, can also increase the risk of developing PVCs.

If you are experiencing occasional PVCs Your doctor may suggest lifestyle changes and medication. If they are a regular occurrence, you may have to avoid certain foods and beverages, such as alcohol and caffeine. You can also take steps to reduce your stress, and get plenty of sleep and exercise.

If you have many PVCs Your doctor may recommend a medical procedure referred to as radiofrequency catheter ablation, which 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 does not prevent them from returning in the future. In certain cases, it may increase the risk of having atrial fibrillation (AFib), an illness that can result in stroke. This is rare but can be life-threatening.

Symptoms

Premature ventricular contractions, or PVCs, can cause your heart appear to flutter or skip one beat. These heartbeats can be harmless, but it is important to consult your physician if you have frequent episodes or signs like dizziness or weakness.

The normal electrical signals start in the sinoatrial region, which is in the upper right part of the heart. They then move to the lower chambers, also known as ventricles, that pump blood. The ventricles then contract to push the blood into the lungs. They return to the heart's center to begin the next cycle of pumping. A PVC starts at a different spot that is the Purkinje fibers are located in the left-hand side of the heart.

When PVCs occur, they cause the heart beat faster or feel like it skipped a beat. If you experience just a few episodes but no other symptoms, the doctor probably won't be able to treat you. If you have many PVCs the doctor may suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. They may also suggest wearing a Holter Monitor which tracks your heart rhythm and counts the number of PVCs.

Anyone who has had a previous heart attack or suffer from cardiomyopathy -- a condition that alters the way the heart pumps blood- must be aware of their PVCs and talk to a cardiologist about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medications to slow the heartbeat, for example, a beta blocker.

If you are experiencing frequent PVCs even if you don't have any other symptoms, you should consult a cardiologist. These irregular heartbeats could signal a problem with the structure of your heart or lungs and if they occur frequently enough, it could weaken your heart muscle. The majority of people with PVCs do not experience any problems. They want to know if the fluttering heartbeats or skipping heartbeats is normal.

Diagnosis

PVCs may feel like heartbeats that are fluttering particularly if they're frequent and intense. People who experience them regularly may feel weak. Exercise can cause them, but most athletes who suffer from them do not have heart or health issues. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors which record electrical impulses that come from your heart. A cardiologist might also use an echocardiogram, which makes use of ultrasound to look at the heart and see how it's working.

A doctor is often able to tell whether a patient has PVCs by looking at them and taking a medical history. But sometimes they might not be aware of them until they examine the patient for other reasons, for basement window maintenance garden window repair - great site - instance following an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect heart disease when there is a concerns.

If your cardiologist has determined that your heart is structurally healthy, reassurance could be all you need. If your symptoms are troubling or cause you to feel anxious, staying away from alcohol, caffeine, and over the counter decongestants, and decreasing stress can aid. Regular exercise, maintaining a healthy weight, insulated window repair and drinking enough fluids can 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 control them.

Treatment

If PVCs aren't common or don't cause symptoms, they don't usually require treatment. If you are frequently affected and frequently, your doctor might want to look for other heart conditions and recommend lifestyle changes or medication. You may also undergo a procedure to get rid of them (called radiofrequency catheter ablation).

If you have PVCs the electrical signal that causes your heartbeat is generated from a place other than the sinoatrial node (SA node) in the top right side of your heart. This could cause it to feel like your heart skips a beat or is beating faster. It's unclear what causes these symptoms, but they're common in people with other heart conditions. PVCs can become more frequent as you age, and may be more frequent during exercises.

If a patient is experiencing frequent and painful PVCs the doctor is required to perform an ECG and an echocardiogram to determine if there is a structural heart problem. They may also perform an exercise stress test to determine if the extra beats are caused by physical exercise. To find out if there are other causes for the increased beats an invasive heart catheterization or cardiac MRI is possible.

The majority of people with PVCs are not affected and live the normal life. They could increase the risk of heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some cases, that means that the heart muscle becomes weaker and has trouble pumping blood throughout your body.

Regular exercise and a balanced diet will lower the risk of developing PVCs. Avoid foods that are high in sodium and fat, and you should also reduce your intake of caffeine and tobacco. Also, you should try to sleep enough and reduce stress. Some medicines can also increase the risk of developing PVCs. If you're taking one of these drugs, it's important to follow your doctor's recommendations about a healthy diet, exercise and taking your medication.

In studies of patients with PVC burdens that are excessive (more than 20% of total heartbeats) there was a higher incidence of arrhythmia-induced cardiac myopathy was found. Some people may need an organ transplant.
