How a VC Can Affect Your Heart
PVCs are common and may be experienced by many people with no cause for concern. If they occur often, PVCs may weaken your heart and increase the risk of heart failure.
The heart's rhythm is controlled by a group of fibers located in the upper right corner of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel to the ventricles, or lower chambers of the heart.
Causes
PVCs occur when the electrical impulse that normally initiates your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. The impulse actually starts in the ventricles, which causes an untimed heartbeat. These extra beats, also known as ventricular tachycardia, or ventricular fibrillation, can feel like your heart skipped a beat or is like it is fluttering. They can occur rarely, causing no symptoms, but they could be frequent enough to affect your quality of life. If they happen frequently or cause weakness, dizziness or fatigue, your doctor may treat them with medication.
PVCs are generally harmless and do not increase the risk of heart disease. In time, frequent PVCs can weaken the heart muscle. This is especially true if the PVCs are caused by an illness like dilated Cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which can lead to heart failure.
window doctor near me of PVCs include a feeling that your heart beats slower or it flutters. You may feel breathless. The fluttering may be more apparent when you exercise or consume certain drinks or foods. PVCs are more prevalent in those suffering from chronic anxiety or stress. Some medications, like digoxin, amiodarone, and cocaine, can increase their risk.
If you have occasional PVCs Your doctor may recommend lifestyle changes and medicines. If they are a regular occurrence, you may need to avoid certain foods and beverages, such as caffeine and alcohol. You can also lessen your stress levels by taking enough rest and working out.
If you have many PVCs Your doctor might suggest a medical procedure called radiofrequency catheter ablation. This procedure destroys the cells that cause them. The procedure is carried out by a specialist, known as an electrophysiologist. It is generally successful in treating the PVCs and reducing symptoms, but it doesn't stop them from occurring in the future. In certain instances, it can increase the risk of atrial fibrillation (AFib) which is a condition that can cause stroke. It is not common, but it could be life-threatening.
Signs and symptoms
Premature ventricular contractions or PVCs, can make your heart seem to skip or flutter a beat. These extra heartbeats are harmless, but you may want to consult 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 top right side of the heart. These signals travel down to the lower chambers (or ventricles) that pump blood. The ventricles then contract to force blood into the lungs. They then return to the center to start the next cycle of pumping. However, a PVC starts at a different spot and is located in the bundle of fibers known as the Purkinje fibers in the left-hand side of the heart.
When PVCs occur, the heart may feel like it is racing or pounding. If you experience a few episodes and no other symptoms, the doctor probably won't be able to treat you. If you've got a lot of PVCs and your doctor might suggest that you undergo an electrocardiogram (ECG) to monitor your heartbeat for a period of 24 hours. He or she might also recommend wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.
Anyone who has had a previous heart attack or suffer from cardiomyopathy -an illness that affects how the heart pumps blood -- should take their PVCs seriously and talk to a cardiologist about lifestyle changes. Those include avoiding caffeine, alcohol and smoking, managing stress and anxiety and getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.
If you experience frequent PVCs even if do not have any other symptoms, you should consult an expert in cardiology. These irregular heartbeats could be a sign of a problem with the structure of your heart or lungs and if they occur often enough, they can weaken the heart muscle. But most people suffering from PVCs do not experience any issues. They are interested in knowing if the rapid heartbeats, or the skipping of heartbeats is normal.
Diagnosis
PVCs can appear to be fluttering or skip heartbeats, especially if they are frequent or intense. People who get lots of them might feel like they're about to faint. Exercise can cause them, but many athletes who experience them do not have heart or health problems. PVCs can be detected in tests like an electrocardiogram (ECG) or Holter monitor. These patches have sensors that record electrical impulses coming from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.
A doctor can often tell whether a patient has PVCs by examining them and taking their medical history. However, sometimes they will only notice them while examining the patient for other reasons, for instance following an accident or surgery. Ambulatory ECG monitors can detect PVCs and other arrhythmias. They can be used to detect cardiac disease when there is a reason to be concerned.
If your cardiologist finds that your heart is structurally normal, reassurance is the only treatment required. If your symptoms are bothersome or make you be anxious, avoiding alcohol, caffeine and over-the drug decongestants and the reduction of stress could aid. Regular exercise and maintaining a healthy weight, and drinking enough fluids can all help reduce the frequency of PVCs. If you are experiencing symptoms that are persistent or severe, talk to your doctor about medications that may be able to manage the symptoms.
Treatment
If PVCs are rare or do not cause symptoms, they do not usually need treatment. If you have them often and frequently, your doctor might want to look for any other heart problems and suggest lifestyle changes or medication. You could also undergo an operation (called radiofrequency cathode ablation) to get rid them.
If you have PVCs the electrical signal that triggers your heartbeat is generated from a place other than the sinoatrial node (SA node) in the top right part of your heart. It can feel like your heart skips a beat or has extra beats. PVCs are more prevalent among people with heart problems, but it's not known the reason behind them. PVCs can increase in frequency as you age, and may occur more frequently during exercises.
If a patient has frequent and painful PVCs, a physician should perform an ECG and an echocardiogram to determine if there is a structural heart problem. The doctor will also likely conduct an exercise stress test to determine if the extra heartbeats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion studies can be done to look for other causes of the increased beats.
Most people who suffer from PVCs do not suffer from any issues and can live a normal lifestyle. However, they can increase your risk of having dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some cases, that means that your heart muscle gets weaker and is having difficulty pumping blood through your body.
Regular exercise and a balanced diet will lower the chances of developing PVCs. You should avoid foods that are high in fat and sodium and limit caffeine and tobacco. Also, you should try to get enough sleep and manage stress. Some medicines can also increase the risk of developing PVCs. If you are taking one of these medicines it is important to follow your doctor's recommendations about eating well, exercising and taking your medication.
Studies of patients who had an excessive amount of PVCs (that's more than 20% of their total heart beats) discovered that they had a higher rate of arrhythmia-induced cardiomyopathy. This can result in the need for a heart transplant in some people.
