How a VC Can Affect Your Heart
PVCs are common and can be experienced by a variety of people with no cause for concern. However, if they happen frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The heart's rhythm is controlled by a bundle of fibers that are located in the upper right-hand corner of your heart. This is known as the sinoatrial node, or SA. Electrical signals travel from there to the lower chambers of your heart, or ventricles.
Causes
PVCs happen by the electrical impulse that normally starts your heartbeat at the Sinus Node (also called the Sinoatrial or SA node) is not initiated. Instead, the impulse is generated in another area of your heart called the ventricles and triggers a mistimed beat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or 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 dizziness, weakness or fatigue, your doctor may treat them with medication.
In most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. Frequent PVCs however, may weaken the heart muscle over time. This is particularly true if the PVCs result from a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.
PVCs can cause symptoms like a feeling of your heart racing one beat, or even fluttering. You might also feel breathless. The fluttering may be more evident when you exercise or consume certain foods or drinks. PVCs are more prevalent in people with chronic anxiety or stress. Some medications, such as digoxin, amiodarone, and cocaine, can also increase the risk.
If you are experiencing occasional PVCs, your doctor may suggest lifestyle changes and medication. If they are a frequent occurrence, you may have to stay clear of certain drinks and foods like caffeine and alcohol. You can also take steps to reduce your stress, and make sure you get enough sleep and exercise.
If you have many PVCs, he may suggest a medical procedure called radiofrequency catheter ablation, which destroys cells that cause PVCs. This is done by a specialist, known as an electrophysiologist. The treatment is generally successful in treating PVCs, reducing symptoms but it does not stop them from returning in the future. In some instances it may increase your risk of having atrial fibrillation (AFib) which can cause stroke. It is not common, but it could be life-threatening.
Symptoms
Premature ventricular contractures PVCs, also known as PVCs, can cause your heart to skip or to flutter. These extra heartbeats are harmless, however you might need to see your doctor in the event of frequent heartbeats or if you notice symptoms such as dizziness or fatigue.
The electrical signals typically begin at the sinoatrial junction, located in the upper right portion of the heart. They travel down to the lower chambers (or ventricles) that pump blood. The ventricles contract to push the blood into the lung. They return to the center to begin the next cycle of pumping. A pvc doctor; Read the Full Content, begins in a different place in the Purkinje fibres bundle in the left side of the heart.
When PVCs occur, they make the heart beat faster or feel like it skipped the beat. If you have only a few episodes, and there are no other symptoms your cardiologist may not be able to treat you. However, if you have large number of PVCs and you have other symptoms, your doctor might suggest an electrocardiogram, or ECG to determine your heartbeat over a 24-hour period. He or she might also recommend wearing a Holter monitor that will track the heart's rhythm over time to determine how many PVCs you have.
People who have suffered an earlier heart attack or have suffered from cardiomyopathy - a condition which affects the way the heart pumps blood - must take their PVCs seriously and speak to a cardiologist about lifestyle modifications. This includes abstaining from caffeine, alcohol, and smoking, reducing anxiety and stress, and getting enough rest. A cardiologist might prescribe medications to slow the heartbeat such as a beta blocker.
Even if there aren't any other symptoms, you should still get PVCs checked by a cardiologist if they happen frequently. These extra heartbeats may indicate a problem in the structure of your heart or lungs, and if they occur frequently enough, it could weaken the heart muscle. The majority of people with PVCs do not have any issues. They just want to be aware that the fluttering and skipping heartbeats aren't normal.
Diagnosis
PVCs may feel like heartbeats that are fluttering particularly if they're frequent and intense. People who experience them frequently may feel faint. Exercise can cause PVCs, but a lot of athletes who experience them do not have heart or health issues. PVCs may show up in tests such as an electrocardiogram (ECG) or Holter monitor. They have sensors that record electrical impulses coming from your heart. A cardiologist may also perform an echocardiogram that uses ultrasound to study the heart and determine how it's working.
A doctor can often tell whether a patient has PVCs by conducting a thorough examination and taking a medical history. Sometimes it is possible that they only be able to detect PVCs when they examine a patient for another reason such as following an accident or surgical procedure. 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 concern.
If your cardiologist concludes that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are causing you discomfort or cause you to be anxious, avoiding alcohol, caffeine and other over the drug decongestants and the reduction of stress could help. Regular exercise, being at a healthy weight and drinking enough water can reduce your episodes of PVCs. If the symptoms persist or are extreme, talk to your doctor about medications that can control these symptoms.
Treatment
If PVCs are rare or don't cause symptoms, they rarely need treatment. If they occur frequently your doctor may need to examine for heart problems or suggest lifestyle modifications. You might also get a procedure to get rid of them (called radiofrequency catheter ablation).
If you suffer from PVCs The electrical signal that triggers your heartbeat begins somewhere other than the sinoatrial node (SA node) in the top right corner of your heart. This can cause your heart to feel like it skips a beating or has extra beats. It's not clear what causes these symptoms, but they're frequent in those with other heart issues. PVCs are more frequent as we age and can occur more frequently during exercising.
A doctor should conduct an ECG as well as an echocardiogram on a patient that has frequent and painful PVCs to rule out structural heart diseases. The doctor may also conduct an exercise stress test to determine if the increased heartbeats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study could be conducted to determine other causes for the increased beats.
The majority of people with PVCs do not experience any complications and can lead an ordinary life. But they can increase the risk of developing dangerous heart rhythm problems, especially if you have certain patterns of them. In some cases, this means that the heart muscle gets weaker and has difficulty pumping blood throughout the glass doctor body.
Regular exercise and a balanced diet will lower your chances of developing PVCs. You should avoid foods that are high in sodium and fat as well as reduce your intake of caffeine and tobacco. Stress and sleep are also important. Some medicines can also increase the double glazing doctor risk of getting 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.
Studies of patients with a high burden of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
