Five Pvc Doctor Lessons From The Professionals
How a VC Can Affect Your Heart
Many people have occasional PVCs without any problems. 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-hand corner of your heart (the sinoatrial node, also known as SA) usually controls your heart rhythm. Electrical signals travel from this node to the lower heart chambers, or ventricles.
Causes
PVCs occur when the electrical impulse that normally starts your heartbeat in a part known as the sinus node (also called the sinoatrial node or SA node) doesn't. Instead, the impulse begins in a different part of your heart called the ventricles and triggers an untimed beat. These extra beats are known as ventricular tachycardia and ventricular fibrillation. They may feel like the heart beats faster or feels like it is fluttering. They may happen rarely and have no symptoms or they can occur frequently enough to affect your quality of life. If they happen frequently or cause dizziness, weakness or fatigue, your doctor could treat them with medicine.
PVCs are generally safe and do not increase the risk of heart disease. Regular PVCs however, could weaken the heart muscle over time. This is particularly relevant if they are triggered by a heart condition like dilated cardiomyopathy, or arrhythmogenic right ventricular cardiomyopathy which could lead to symptoms of heart failure.
The symptoms of PVCs include a feeling that your heart skips a beat or flutters, and you may feel breathless. The fluttering may be more apparent when you exercise or have certain foods or drinks. PVCs are more prevalent in those suffering from chronic anxiety or stress. Some drugs, like digoxin, amiodarone, and cocaine, can increase the risk.
If you have occasional PVCs Your doctor might recommend lifestyle changes and medicines. If you are prone to frequent PVCs, your doctor may recommend that you avoid certain drinks and foods, such as caffeine and alcohol. You can also reduce your stress levels by taking enough rest and working out.
If you have many PVCs Your doctor might suggest a medical procedure known as radiofrequency catheter ablation. This procedure eliminates the cells responsible for them. This procedure is performed by a specialist, known as an electrophysiologist. The treatment is usually effective in treating PVCs, reducing symptoms but it does not stop them from returning in the future. In certain cases, it can increase your risk of atrial fibrillation (AFib) which could lead to stroke. It is not common, but it could be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, can make your heart appear to skip or flutter the beat. These heartbeats can be harmless, however, you should consult your physician in case you experience frequent episodes or symptoms like dizziness or weakness.
window doctors repairmywindowsanddoors.co.uk begin in the sinoatrial node, which is in the top right portion of the heart, and move down to the lower chambers (or ventricles) that pump blood. The ventricles contract to force blood into the lung. They return to the heart's center to begin the next cycle of pumping. However, a PVC begins at a different spot and is located in the bundle of fibers called the Purkinje fibers, in the lower left part of the heart.
When PVCs occur and the heart is affected, it may feel as if it's racing or pounding. If you've experienced just a few episodes but no other symptoms, your doctor probably won't be able to treat you. If you have many PVCs, your doctor may recommend that you undergo an electrocardiogram (ECG) to measure the heartbeat for 24 hours. They may also suggest wearing a Holter monitor, which will record your heart rhythm over time to determine the number of PVCs you have.
Anyone who has suffered a previous heart attack or have suffered from cardiomyopathy - an illness that affects method by which the heart pumps blood - must take their PVCs seriously and consult a cardiologist regarding lifestyle changes. These include cutting down on caffeine, alcohol and smoking, reducing stress and anxiety, as well as getting enough rest. A cardiologist may prescribe beta blockers to slow the heartbeat.
If you experience frequent PVCs, even if you don't have any other signs, you should see a cardiologist. These irregular heartbeats could 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 don't experience any issues. They would like to know if fluttering heartbeats or skipping heartbeats is normal.
Diagnosis
PVCs can feel like heartbeats that are fluttering, particularly if they're frequent and intense. People who experience them regularly may feel faint. They can also happen with exercise, though many athletes who experience them do not have any issues in their heart or health. PVCs can be detected on tests such as an electrocardiogram, or Holter monitor. These use sticky patches with sensors that record electrical impulses from your heart. A cardiologist may also use an ultrasound echocardiogram to examine the heart.
A doctor is often able to tell the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes, they may not be aware of them until they examine the patient for other reasons, for instance after a surgery or accident. Ambulatory ECG monitoring systems can aid in detecting PVCs and other arrhythmias, and can be used if there's any concern of cardiac disease.
If your cardiologist concludes that your heart's structure is normal, reassurance will be the only treatment needed. If your symptoms are causing discomfort or cause you to feel anxious, avoiding alcohol, caffeine, and other decongestants and reducing stress may help. Engaging in regular exercise, keeping at a healthy weight, and drinking enough water can reduce your episodes of PVCs. If the symptoms persist or are severe, speak to your doctor about medication options to treat the symptoms.
Treatment
If PVCs are rare or don't cause symptoms, they do not usually require treatment. If they are frequent your doctor may need to examine for heart problems or suggest lifestyle adjustments. You could also have an operation (called radiofrequency cathode ablation) to eliminate them.
When you have PVCs The electrical signal that triggers your heartbeat is generated from a place outside of the sinoatrial node (SA node) located in the upper right part of your heart. This could cause your heart to feel as if it skips beats or has extra beats. They're more common among people who suffer from heart issues, but it's not known the reason behind them. PVCs are more likely to occur as you age, and may be more frequent during exercises.
A doctor should perform an ECG and an echocardiogram on a patient who has frequent and painful PVCs to determine if there are structural heart problems. The doctor will also likely perform an exercise stress test in order to determine if the increased heartbeats are related to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other causes of the additional beats.
Most people who suffer from PVCs do not experience any complications and can lead an ordinary life. But they can increase the risk of developing dangerous heart rhythm problems particularly if you have certain patterns of them. In some instances, this means that the heart muscle becomes weaker and has difficulty pumping blood throughout 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 you should also reduce your intake of caffeine and tobacco. Sleep and stress are equally important. Certain medicines can also increase the risk of developing PVCs. So if you take one of these medications, it's important to follow your doctor's instructions about eating well, exercising and taking your medication.
Studies of patients with a high amount of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Some patients may require a heart transplant.
