How a VC Can Affect Your Heart
A lot of people experience occasional PVCs without any problems. If they are frequent, PVCs may weaken your heart and increase your chance of suffering from heart failure.
The heart's rhythm is controlled by a group of nerve fibers situated in the upper right-hand part of your heart. This is known as the sinoatrial nerve, or SA. Electrical signals travel to the lower heart chambers or ventricles.
Causes
PVCs are caused when the electrical impulse that typically starts your heartbeat in a region called the sinus node (also called the sinoatrial or SA node) isn't. The impulse actually begins in the ventricles, which causes an untimed heartbeat. These extra beats are also called ventricular tachycardia or ventricular fibrillation. They may feel like the heart skipped a beat or feels fluttering. They can occur infrequently and cause no symptoms, or they can happen often enough to interfere with your quality of life. If they are very frequent or cause weakness, dizziness or fatigue, your doctor may treat them with medication.
PVCs are generally harmless and do not increase your risk of heart disease. Frequent PVCs however, may weaken your heart muscle over time. This is especially true if the PVCs are triggered by conditions like dilated cardiomyopathy and arrhythmogenic right ventricle cardiomyopathy that could lead to heart failure.
The signs of PVCs include feeling like your heart skips a beat or is fluttering, and you feel breathless. The fluttering can be more evident when you exercise or consume certain drinks or foods. PVCs are more common for those who suffer from chronic anxiety or stress. Some medications, such as digoxin, amiodarone and cocaine, can increase the risk of developing PVCs.
If you have occasional PVCs your doctor might suggest lifestyle changes and medications. If you are prone to frequent PVCs, your physician may recommend that you avoid certain foods and drinks such as caffeine and alcohol. You can also reduce your stress by getting enough sleep and working out.
If you're experiencing many PVCs The doctor may recommend a medical treatment known as radiofrequency catheter ablation. This eliminates the cells that cause PVCs. windowdoctor is done by a specialist called an electrophysiologist. It is usually successful in treating the PVCs and reducing symptoms, however it does not stop them from recurring in the future. In certain cases, it can increase the risk of developing atrial fibrillation (AFib) which can result in a stroke. This is rare but can be life-threatening.
Symptoms
Premature ventricular contractions, or PVCs, may make your heart appear to flutter or skip one beat. These heartbeats that are not normal can be harmless, however you might want to consult your doctor in the event of frequent heartbeats or if you experience symptoms like dizziness, or fatigue.
Normally, electrical signals start in the sinoatrial node, which is in the top right side of the heart, and travel down to the lower chambers (or ventricles) which pump blood. Then, the ventricles expand to push blood into your lungs and then return to the heart to start the next pumping cycle. However, a PVC starts in a different location, from the bundle of fibers called the Purkinje fibers in the left-hand side of the heart.
When PVCs occur, the heart may appear to be racing or pounding. If you have just a few episodes but no other symptoms, the cardiologist probably won't treat you. If you have many PVCs, your doctor may suggest 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 tracks your heartbeat and tracks the number of PVCs.
Anyone who has suffered an earlier heart attack or cardiomyopathy, an illness that affects way the heart pumps blood - should take their PVCs very seriously and speak to a cardiologist regarding lifestyle modifications. These include cutting down on caffeine, alcohol and smoking, managing stress and anxiety, as well as getting enough rest. A cardiologist can prescribe medications to slow heartbeat, for example, a beta blocker.
Even if you don't have any other symptoms it is still recommended to have PVCs examined by a cardiologist if they happen often. These extra heartbeats may signal a problem with the structure of your heart or lungs and if they happen often enough, they can weaken the heart muscle. However, most people suffering from PVCs don't experience any problems. They simply want to be aware that the fluttering and skippy heartbeats aren't typical.
Diagnosis
PVCs may feel like heartbeats that are fluttering, particularly if they're frequent and intense. Patients who have a lot of them may feel they're about to faint. Exercise can trigger PVCs, but a lot of athletes who suffer from these symptoms do not have heart or health issues. PVCs could show up in tests like an electrocardiogram (ECG) or Holter monitor. These patches contain sensors that record electrical impulses from your heart. A cardiologist could also employ an echocardiogram, which makes use of ultrasound to look at the heart and observe how it's functioning.
A doctor will usually be able to determine the presence of PVCs by conducting a thorough examination and taking a medical history. Sometimes, however, they may only notice PVCs when examining the patient for another reason, such as after an accident or a surgery. Ambulatory ECG monitoring systems can help detect PVCs and other arrhythmias, and can be used if there's any concern of heart disease.
If your cardiologist has determined that your heart is structurally healthy, reassurance might be all you need. If your symptoms are troubling or make you feel anxious, staying away from alcohol, caffeine, and other decongestants and reducing stress can aid. Engaging in regular exercise, keeping at a healthy weight and drinking enough fluids can decrease the likelihood of PVCs. If your symptoms persist or severe, speak to your physician about the medications that may be able to manage them.
Treatment
If PVCs aren't common or don't cause symptoms, they do not usually require treatment. If they occur frequently, your doctor might need to examine for heart problems or suggest lifestyle changes. You may also undergo an operation to rid yourself of them (called radiofrequency catheter ablation).
When you have PVCs, the electrical signal that triggers your heartbeat starts somewhere different than the sinoatrial nerve (SA node) in the top right side of your heart. This can cause your heart to feel like it skips beats or has additional beats. They're more common among people who suffer from heart issues however it's unclear the reason behind them. PVCs are more frequent as we age and can occur more often during exercises.
A doctor should perform an ECG and an echocardiogram on a patient that suffers from frequent and painful PVCs to determine if there are structural heart problems. The doctor will also perform an exercise stress test in order to determine if the extra heartbeats are related to physical activity. A heart catheterization or cardiac MRI or nuclear perfusion study can be done to look for other causes of the increased beats.
The majority of people with PVCs do not have any issues and can lead the normal life. However, they can increase the risk of developing dangerous heart rhythm issues especially if you are suffering from certain patterns of them. In some instances, this means that the heart muscle becomes weaker and has trouble pumping blood through your body.
A healthy, regular diet and regular exercise can reduce the risk of developing PVCs. Avoid foods high in fat and sodium, and limit your consumption of tobacco and caffeine. Sleep and stress are equally crucial. Some medicines may also increase your risk of getting PVCs. If you are taking any of these medicines it is essential that you follow the advice of your doctor regarding eating a healthy diet exercising, as well as taking your medication.
Studies of patients suffering from a high burden of PVCs (that's more than 20 percent of their total heart beats) found that they had a higher rate of arrhythmia-induced cardiomyopathy. Certain people may require an organ transplant.
