How a VC Can Affect Your Heart
A lot of people experience occasional PVCs without any problems. If they occur regularly, PVCs can weaken your heart muscle and increase the risk of heart failure.
A bundle of fibers located in the top right portion of your heart (the sinoatrial or SA node) usually controls the heart's rhythm. Electrical signals travel to lower heart chambers or ventricles.
Causes
PVCs are caused by the electrical impulse that normally starts your heartbeat at the Sinus Node (also known as the Sinoatrial or SA node) does not. Instead, the impulse begins in another area of your heart, the ventricles, and causes a wrongly timed beat. These extra beats, called ventricular tachycardia or ventricular fibrillation, can feel like your heart skipped a beat or is like it is fluttering. They can occur rarely and not cause any symptoms, but they may occur frequently enough to affect your standard of living. If they are very frequent or cause dizziness, weakness, or fatigue, your doctor could treat them with medicine.
For most people, PVCs are harmless and aren't likely to increase your risk of heart disease or other health issues. In time, frequent PVCs can weaken the heart muscle. This is particularly the case if they are caused by a heart disease such as dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy, which may lead to symptomatic heart failure.
The symptoms of PVCs include a feeling that your heart skips a beat or it flutters. You may feel exhausted. The fluttering could be more apparent when you exercise or consume certain drinks or food items. PVCs are more common for those who suffer from chronic anxiety or stress. Certain drugs, like digoxin, amiodarone or cocaine, can also increase their risk.
If you have occasional PVCs, your doctor may suggest lifestyle changes and medications. If you experience frequent PVCs, your doctor may recommend that you avoid certain foods and drinks, such as caffeine and alcohol. You can also lower your stress levels by taking enough rest and exercising.
If you're experiencing a lot of PVCs, he may suggest a medical procedure called radiofrequency catheter ablation. It destroys the cells that are responsible for PVCs. Electrophysiologists are the ones who perform this procedure. It is usually effective in treating PVCs and reducing symptoms, however, it doesn't prevent them from recurring in the future. In certain instances, it can increase the door doctor risk of developing atrial fibrillation (AFib) which is which can lead to stroke. It's not common, but it can be life-threatening.
Signs and symptoms
Premature ventricular contractions, or PVCs can cause your heart to skip or be fluttering. These extra heartbeats are usually harmless, however, you should consult your physician in case you experience frequent episodes or signs like dizziness or weakness.
Normaly, electrical signals begin in the sinoatrial area, which is located in the upper right part of the heart. They then move to the lower chambers, or ventricles, where blood pumps are located. The ventricles contract to propel the blood into the double glazing doctor lungs, and then return to your heart and start the next cycle of pumping. A PVC begins in a different place in the Purkinje fibres bundle in the bottom left of the heart.
When PVCs occur they can make the heart feel like it is skipping a beat or pounding. If you've experienced a few episodes and no other symptoms, the doctor will probably not treat you. If you've got a lot of PVCs the doctor may suggest you undergo an electrocardiogram (ECG) to monitor your heartbeat for 24 hours. They may also recommend wearing a Holter Monitor, which records the heart's rhythm and count the number of PVCs.
Anyone who has had a prior heart attack or have cardiomyopathy -- a condition that alters the way the heart pumps blood -- must be aware of their PVCs and talk to a cardiologist about lifestyle changes. This includes abstaining from caffeine, alcohol, and smoking, reducing stress and anxiety, and getting enough rest. A cardiologist may prescribe beta blockers to slow down the heartbeat.
Even if you don't have any other indications it is still recommended to have PVCs checked by an expert in cardiology if they occur often. These heartbeats that are irregular could signal a problem with the structure of your lungs or heart, and if they occur frequently enough, can weaken your heart muscle. But the majority of 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 be felt as fluttering or skipped heartbeats, especially when they're frequent or intense. People who experience them frequently might feel faint. They can also happen with exercise, though many athletes who get them don't have any problems in their heart or health. PVCs can be detected in tests such as an electrocardiogram (ECG) or Holter monitor. These use sticky patches with sensors to record electrical impulses from your heart. A cardiologist could also employ an ultrasound echocardiogram to examine the heart.
A doctor will usually be able to determine if a patient has PVCs by looking at them and taking a medical history. Sometimes, they may only be able to detect them when they examine the patient for other reasons, for instance after an accident or surgery. Ambulatory ECG monitoring systems also assist in detecting PVCs and other arrhythmias, and can be used in the event of any suspicion of heart disease.
If your cardiologist has determined that your heart is structurally healthy, reassurance may be all you need. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine and other decongestants as well as reducing stress levels can help. Regular exercise and maintaining a healthy weight and drinking enough fluids can help reduce the frequency of PVCs. If the symptoms persist or are severe, talk with your physician about possible medication options to treat the symptoms.
Treatment
If PVCs aren't causing symptoms or happen rarely, they usually don't need treatment. If you experience them frequently, your doctor may want to check for other heart conditions and suggest lifestyle changes or medications. You may also undergo an intervention to get rid of them (called radiofrequency catheter ablation).
If you suffer from PVCs the electrical signal that triggers your heartbeat is generated from a place different than the sinoatrial nerve (SA node) located in the upper right corner of your heart. This could cause your heart to feel as if it skips a beating or has extra beats. They're more common among people with heart problems however it's unclear the reason behind them. PVCs can become more frequent as you age, and may be more frequent during exercising.
If a patient is experiencing frequent door and window doctor painful PVCs doctors should conduct an ECG and an echocardiogram to rule out heart disease that is structural. They may also perform an exercise stress test to see if the extra beats are due to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be conducted to determine other reasons for the extra beats.
The majority of people who suffer from PVCs do not have any issues and can live the normal life. They can increase the risk of developing dangerous heart rhythm disorders, especially if they occur in certain patterns. In some instances, this means that the heart muscle gets weaker and has difficulty pumping blood throughout your body.
Regular exercise and a healthy diet can lower your chances of developing PVCs. Avoid foods that are high in fat and sodium and limit your intake of caffeine and tobacco. You should also try to get enough sleep and manage stress. Certain medications can increase the risk of developing PVCs. If you are taking any of these medicines it is essential to follow your doctor's recommendations regarding eating a healthy diet, exercising, and taking your medication.
In studies of patients with pvc doctor burdens that are excessive (more than 20% of the total heartbeats) the higher rate of arrhythmia-induced cardiac myopathy was discovered. Some patients may require a heart transplant.
