Why It’s Important to See a Doctor
Premature ventricular contracts (PVCs), are a kind of irregular heartbeat. These extra beats are usually not hazardous, and they could disappear by themselves.
Doctors will listen to your heartbeat and also check other vital indicators. They may also order an Holter Monitor, which records the electrical impulses generated by your heart over a time of between 24 and 48 hours. They can also order blood tests for checking your electrolyte levels and thyroid hormones.
Diagnosis
PVCs are caused by electrical impulses which misfire through the SA node, a structure located in the lower chambers of the heart. This causes the heartbeat to be delayed and causes a feeling of fluttering or skipped beats in the chest. PVCs may occur alone or in repeated patterns. Two consecutive PVCs are referred to as doublets, while three or more consecutive PVCs constitute the term ventricular tachycardia (VT).
Some people don’t experience any symptoms Others experience heart palpitations which could feel like an irregular heartbeat or a pounding. Other signs include dizziness, fatigue, or feeling unwell.
Many people with occasional PVCs do not require treatment. If someone is experiencing frequent episodes, doctors may suggest a change in diet or lifestyle including a reduction in caffeine, alcohol and stress. They may also prescribe medications such as beta-blockers or calcium channel blockers, which can slow the heart rate and lower blood pressure.
Doctors will ask about the person’s medical history and perform a physical examination to assess their general health. They may also use an electrocardiogram (ECG) to capture a snapshot of the heart’s electrical activity, or a Holter monitor that is worn for longer durations and records the heart’s rhythms over time. In certain cases doctors may require blood tests to look for an electrolyte imbalance or toxic effects from drugs.
Occasionally, a pvc doctor may refer a patient to a specialist in heart rhythm problems, or an electrophysiologist, for further evaluation. This doctor can confirm the diagnosis of PVCs and determine if they are benign or not.
PVCs are fairly common and don’t usually cause any issues, unless they occur frequently over a long time. This could lead to a weakening of the heart muscle or a condition known as pvc-induced cardiomyopathy. This is most common in people who are older or those with some type of heart disease. It can also happen in healthy people with an uninvolved heart, however this is more likely in those who exercise regularly. Usually, this isn’t a serious concern, but it is important to consult an expert if you notice symptoms like fainting or fatigue.
Treatment
For many people, occasional PVCs aren’t likely to cause symptoms or need no treatment. If you notice that your heart is racing or skipping the beat, it’s best to seek out a physician immediately.
A cardiologist will first interview you and conduct an examination of your body and listen to your heart through an stethoscope to identify any irregular beats. You will also undergo an electrocardiogram, which records the electrical signals of your heart to determine any arrhythmias. If an arrhythmia is identified then an all-day Holter monitor or a portable ECG is required to record the abnormal rhythm over longer periods of time. These devices will assist doctors determine if you suffer from PVCs and the reason behind them, such as an electrolyte imbalance, a drug toxicities, or other causes.
An echocardiogram, also known as an ultrasound of your heart, could be ordered to determine if your heart is healthy and to look for indications of structural issues that can lead to PVCs. You may also be asked to take stress tests to assess how your heart reacts to exercise. Physical activity can increase the frequency of pvcs. You can also take blood tests to check your thyroid hormone and magnesium, potassium, and other hormones to determine whether they’re low. This can lead to PVCs.
After your doctor confirms that you suffer from PVCs and has ruled any serious illness out, the decision to treat them will depend on how they affect your life and how frequently they occur. If they only occur occasionally and don’t cause any symptoms, it’s unlikely that your doctor will recommend any medication to reduce their frequency or severity.
If you experience frequent PVCs that cause palpitations or other symptoms like feeling lightheaded or fainting, your doctor may prescribe medications such as beta blockers and calcium channel blockers. Changing your lifestyle to stay clear of triggers, such as smoking, caffeine, and excessive stress, can also reduce the frequency of times you experience these abnormal pulses.
Prevention
A person may experience no symptoms whatsoever from PVCs or experience heart palpitations (irregular heartbeats) which can be felt as “skipped” beats or fluttering in the chest. These episodes can cause feelings of fullness or pressure, or they can make you feel faint. These episodes occur because the heart isn’t functioning as efficiently as it should. Frequent PVCs increase the risk of developing dilated Cardiomyopathy, a condition in which the heart enlarges and becomes ineffective at pump blood.
PVCs are usually caused by changes in the body’s chemical. This is due to the release of thyroid hormones and adrenaline as well as drinking alcohol or caffeine. A lack of exercise can also trigger these episodes and stress, as well as excessive weight.
Certain people find that altering their diet can reduce the number of PVCs. They can, for example, avoid foods that are preservative-laden, which can cause a disturbance of the heart rhythm. These include disodium Guanylate, diazole, and disodium Inosinate Sodium (E282-283). Eat more fruits and vegetables to ensure that you get sufficient magnesium.
It is crucial to undergo regular health checks, including annual physicals and laboratory tests. These tests can help diagnose any heart conditions that may be causing your PVCs. You should also not smoke and adhere to an appropriate diet program. This could increase the frequency of episodes.
A survey of 14 regular hospital wards showed that healthcare staff were generally aware of preventive measures for vascular catheter-associated infection, but their self-assessed conformity to these practices was low. After a feedback program, compliance improved on some areas, but was still very low. This suggests that training on how to implement preventive measures is required and that the areas that are not as well-adjusted should be targeted for infection surveillance. This information can be used to help in the implementation of quality improvement initiatives on these wards. This will likely involve further education and training for personnel. It will also require making sure that the appropriate materials are available for the implementing of the preventive measures.
Signs and symptoms
If you feel your heart is racing or fluttering, it could be premature ventricular contractions. These arrhythmias aren’t necessarily dangerous or they may be a sign of serious heart problems.
In healthy people, PVCs that occur occasionally are not a problem. They usually disappear on their own. If you’re suffering from a lot of them, they could lead to dizziness or weakness. Speak to your doctor if concerned. They might need to diagnose the problem by taking an history of your medical condition and performing an examination. They might also conduct an electrocardiogram, or other tests.
An ECG is a test that’s quick that lets your health care provider observe the signal generated by your heartbeat as it travels through your heart in a short period of time. The test will show whether you have PVCs. Your door doctor may also suggest to perform an overnight or 24-hour Holter monitor which monitors your heartbeat for longer durations of time. These tests can help distinguish PVCs from arrhythmias that cause heart palpitations. You can also wear an event monitor, which is a portable device which tracks your heart’s rhythm over 30 days.
Other tests for your heart might be required, depending on the reason behind your PVCs. For example an cardiologist may test your blood pressure and do an ultrasound of your heart (echocardiogram). These tests can reveal the presence of a medical condition that is causing your PVCs like mitral valve prolapse or heart failure.
Your doctor might also need to do an examination of your blood to determine what’s wrong with your electrolytes such as low potassium or high levels of calcium. This could be an indication of PVCs or other conditions that can cause them, including anxiety disorders and anemia.
You may be referred to an electrophysiologist who can treat irregular heart rhythms. The specialist might need to conduct additional tests if you suffer from structural heart diseases like the CT or MRI scan of your chest. These tests will tell you whether you’ve suffered damage to your heart and how severe it is. In some cases doctors may suggest pacemakers to treat the condition that causes the PVCs.
