How a VC Can Affect Your Heart
Many people experience occasional PVCs and have no issues. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
A bundle of fibers in the upper right part of your heart (the sinoatrial or SA node) usually controls your heart's rhythm. Electrical signals are transmitted from there to the lower heart chambers, or ventricles.
Causes
PVCs are caused when the electrical impulse that normally triggers your heartbeat at the Sinus Node (also called the Sinoatrial or the SA node) does not. Instead, the impulse starts in a different area of your heart--the ventricles--and causes an untimed beat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat or feels like it's fluttering. They can occur infrequently and have no symptoms or they may occur frequently enough to affect your quality of life. If they occur frequently or cause weakness, dizziness, or fatigue, your doctor could treat them with medication.
PVCs are generally harmless and don't increase your risk of developing heart disease. Frequent PVCs, however, can weaken your heart muscle over time. This is especially the case if they are caused by a heart condition such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which can lead to symptomatic heart failure.
PVCs can trigger symptoms such as a feeling of your heart skipping one beat, or even fluttering. You might also feel breathless. The fluttering can be more noticeable when you exercise or eat or drink certain beverages or foods. PVCs are more prevalent in those suffering from chronic stress or anxiety. Some medications, like digoxin, amiodarone and cocaine, can also increase their risk.
If you experience occasional PVCs Your doctor might suggest lifestyle changes and medication. If they're a frequent occurrence, you may have to avoid certain drinks and foods, such as caffeine and alcohol. You can also lower your stress levels by getting enough sleep and exercising.
If you're suffering from a lot of PVCs, he may suggest a medical treatment called radiofrequency catheter ablation. It destroys cells that cause PVCs. This is done by a specialist, known as an electrophysiologist. It is typically effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In some cases it can increase your risk of having atrial fibrillation (AFib), which can cause stroke. It's not common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contracts, or PVCs can cause your heart to skip or flutter. These extra heartbeats are harmless, but you might need to see your doctor if they are frequent or if you are experiencing symptoms like dizziness, or fatigue.
The electrical signals normally begin in the sinoatrial area, which is located in the upper right corner of the heart. They then travel to the lower chambers, also known as ventricles, where blood pumps are located. The ventricles contract to propel the blood into your lungs, and return to the heart to begin the next pumping cycle. But a PVC begins in a different place that is separate from the bundle of fibers known as the Purkinje fibers, located in the bottom left portion of the heart.
When PVCs happen, the heart may appear to be skipping a beat or pounding. If you only have a few episodes, and no other symptoms are present your cardiologist may not be able to treat you. However, if you have number of PVCs the doctor may recommend an electrocardiogram, also known as an ECG to determine the heart's rate over 24 hours. He or she may also suggest wearing a Holter monitor that records the heart's rhythm over time to see how many PVCs you have.
Anyone who has suffered an earlier heart attack or have suffered from cardiomyopathy - a condition which affects the method by which the heart pumps blood - must take their PVCs seriously and speak to an expert in cardiology about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe beta blockers to slow the heartbeat.
If you are experiencing frequent PVCs, even if you do not have other signs, you should see an expert in cardiology. window doctor could point to an issue with the structure of your heart or other health issues and, over time, if they occur often enough, they could weaken the heart muscle. The majority of people with PVCs don't experience any problems. They just want to be aware that the fluttering and racing heartbeats aren't normal.
Diagnosis
PVCs may feel like heartbeats that flutter, particularly if they're frequent and intense. People who experience them regularly may feel faint. Exercise can trigger them, but many athletes who experience them have no heart or health problems. PVCs can show up in tests like an electrocardiogram or a Holter monitor. They use sticky patches with sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's functioning.
A doctor may be able to identify if a person is suffering from PVCs from a history and physical exam. But sometimes they might not be aware of them until they examine the patient for other reasons, such as following an accident or surgery. Ambulatory ECG monitors are able to detect PVCs, as well as other arrhythmias. They are able to detect heart disease in the event of any concern.
If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment needed. If your symptoms are causing discomfort or make you feel anxious, avoiding alcohol, caffeine, and other decongestants as well as reducing stress levels can help. Regular exercise, being at a healthy weight, and drinking enough water can also decrease the likelihood of PVCs. If your symptoms persist or severe, speak to your doctor about medication that may be able to control the symptoms.
Treatment
If PVCs don't cause symptoms or are not frequent generally, they don't require treatment. If you experience them frequently and frequently, your doctor might want to examine for other heart issues and suggest lifestyle changes or medications. You could also have a procedure (called radiofrequency cathode ablation) to get rid them.
If you have PVCs, the electrical signal that causes your heartbeat starts somewhere different than the sinoatrial nerve (SA node) located in the upper right side of your heart. double glazing doctor can cause your heart to feel like it skips beats or has extra beats. They're more common among people who suffer from heart issues however, it's not clear what causes them. PVCs are more frequent with age and might happen more frequently during exercises.
If a patient is experiencing frequent and painful PVCs the doctor should perform an ECG and an echocardiogram to rule out structural heart disease. They should also conduct an exercise stress test to determine whether the additional beats are a result of physical exercise. To find out whether there are any other causes for the extra beatings, a heart catheterization or a cardiac MRI can be performed.
The majority of people who suffer from PVCs do not have any issues and can lead a normal life. They can increase the risk of heart rhythm disorders that can be dangerous particularly if they happen in certain patterns. In some cases, that means the heart muscle gets weaker and has trouble pumping blood through your body.
A healthy, regular diet and plenty of exercise can reduce your risk of developing PVCs. Avoid foods that are high in fat and sodium and limit caffeine and tobacco. Also, you should try to get enough rest and manage stress. Some medicines can also increase your risk of PVCs. If you are taking any of these medicines it is essential to follow your doctor's advice regarding eating a healthy diet and exercising as well as taking your medication.
In studies of patients with high PVC burdens (more than 20% of heartbeats), a higher rate arrhythmia-induced myopathy in the heart was observed. Certain people may require an organ transplant.
