How a VC Can Affect Your Heart
Many people experience occasional PVCs without any problems. But if they occur frequently, PVCs can weaken your heart muscle and increase the risk of heart failure.
The rhythm of your heart is usually controlled by a group of fibers that are located in the upper right part 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 are caused when the electrical impulse that typically begins your heartbeat at a point called the sinus node (also called the sinoatrial or SA node) doesn't. The impulse actually starts in the ventricles, which causes an irregular heartbeat. These extra beats, known as ventricular tachycardia, or ventricular fibrillation, may feel like your heart skipped a beat, or it feels like it is like it is fluttering. They can happen infrequently and not cause any 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 could treat them with medicine.
PVCs are generally harmless and don't increase your risk of developing heart disease. Frequent PVCs, however, can weaken the heart muscle over time. This is especially when the PVCs are caused by a condition like dilated cardiomyopathy and arrhythmogenic right-ventricular cardiomyopathy, which could lead to heart failure.
The signs of PVCs include a feeling that your heart beats slower or is fluttering, and you feel breathless. The fluttering may be more evident when you exercise or consume certain drinks or foods. PVCs are more prevalent in people with chronic anxiety or stress. Some drugs, like digoxin, amiodarone and cocaine, may increase the risk of developing PVCs.
If you are experiencing occasional PVCs your doctor might suggest lifestyle changes and medication. If you have frequent PVCs, your doctor might suggest that you stay away from certain drinks and foods, such as alcohol and caffeine. You can also take steps to reduce your stress, and take advantage of plenty of rest and exercise.
If you have a lot of PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. It eliminates the cells that are responsible for them. Electrophysiologists are the ones who execute this procedure. It is generally effective in treating PVCs and reducing symptoms, however it does not stop them from recurring in the future. In certain cases, it may increase the risk of atrial fibrillation (AFib) which is an illness that can lead to stroke. This is rare but can be life-threatening.
Symptoms
Premature ventricular contractions or PVCs may cause your heart to skip or be fluttering. These heartbeats that are not normal can be harmless, but you may need to see your doctor if they are frequent or if you are experiencing symptoms like dizziness or fatigue.
Normally, electrical signals begin in the sinoatrial node, which is in the top right-hand side of the heart. They move down to the lower chambers (or ventricles) that pump blood. The ventricles contract to push the blood into the lungs. They then return to the center to begin the next cycle of pumping. A Pvc Doctor starts at a different spot, the Purkinje fibres bundle in the bottom left of the heart.
When PVCs occur, they cause the heart beat faster or feel as if it skipped one beat. If you experience just a few episodes but no other symptoms, your doctor probably won't be able to treat you. If you have a lot of PVCs and your doctor might suggest you undergo an electrocardiogram (ECG) to determine the heartbeat for a period of 24 hours. The doctor may also suggest wearing a Holter Monitor that records your heart rhythm and counts the number of PVCs.
People who have suffered a heart attack in the past or suffer from cardiomyopathy -- a condition that affects how the heart pumps blood -and should take their PVCs seriously and speak with a cardiologist about changes to their lifestyle. These include avoiding caffeine, alcohol and smoking, reducing anxiety and stress and getting enough sleep. A cardiologist may prescribe beta blockers to slow the heartbeat.
If you experience frequent PVCs even if you do not have any other signs, you should see a cardiologist. These heartbeats that are irregular 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 could weaken the heart muscle. But most people with PVCs do not experience any issues. 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 get lots of them may feel they're about to faint. They can also occur with exercise, though many athletes who get them don't have any problems with their heart or health. PVCs could show up in tests such as an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram that uses ultrasound to study the heart and observe how it's working.
A doctor will usually be able to determine whether a patient has 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, like following an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and can be used when there is a concern of heart disease.
If your cardiologist finds that your heart is structurally normal, reassurance will be the only treatment required. If your symptoms are bothersome, or cause you to be anxious, avoiding alcohol, caffeine and over-the drug decongestants and decreasing stress can help. Regular exercise and maintaining a healthy weight, and The Window Doctor Near Me drinking enough fluids can all help to reduce the frequency of PVCs. If your symptoms persist or extreme, consult your physician about the medications that could help reduce the symptoms.
Treatment
If PVCs do not cause any symptoms or are not frequent generally, they don't require treatment. If you have them often and frequently, your doctor might want to check for other heart issues and recommend lifestyle changes or medications. You could also undergo an operation (called radiofrequency cathode ablation) to eliminate of them.
If you have PVCs in your heart the electrical signal that creates your heartbeat is located other than at the sinoatrial (SA) node located in the upper right corner of your heart. This could cause it to feel like your heart skips a beat or has a few extra beats. It's not clear what causes these symptoms, but they're common in people with other heart problems. PVCs can increase in frequency with age and might happen more frequently during exercises.
If a patient has frequent and painful PVCs, a physician is required to perform an ECG and an echocardiogram to rule out heart disease that is structural. The doctor will also perform an exercise stress test in order to determine if the additional heartbeats are due to physical exercise. A heart catheterization, cardiac MRI or nuclear perfusion study can be done to look for other causes for the extra beats.
The majority of people who suffer from PVCs do not experience any issues and can live a normal lifestyle. They could increase the risk of dangerous heart rhythm disorders, especially if they occur in certain patterns. In certain cases, it means the heart muscle gets weaker and is having difficulty pumping blood through your body.
A healthy, regular diet and a lot of exercise can help reduce your risk of developing PVCs. Avoid foods high in fat and sodium, and limit your intake of tobacco and caffeine. Stress and sleep are also important. Some medicines can also increase the risk of getting PVCs. If you are taking one of these drugs it is important to follow your doctor's instructions about eating well, exercising and taking your medication.
Studies of patients who had a high amount of PVCs (that's more than 20% of their total heart beats) found that they had a higher incidence of arrhythmia-induced cardiomyopathy. This can lead to the need for a heart transplant in a few people.
