Why It's Important to See a Doctor

Premature ventricular contracts (PVCs) are a form of irregular heartbeats. These extra beats aren't usually risky, and they may disappear by themselves.

Doctors will monitor your heartbeat and look for other vital signs. They may order a Holter monitor which is a device that records your heart's electrical impulses over the course of 24 hours. They can also order blood tests to assess your electrolyte levels and thyroid hormones.

Diagnosis

PVCs are caused by electrical impulses coming from the heart's lower chambers ventricles, or lower chambers, fail to pass through a structure known as the SA node. This delays the next heartbeat, causing the feeling of fluttering or skipped beats in the chest. PVCs can be seen in a single pattern or in repeated patterns. Doublets are PVCs that occur in a series of. Ventricular tachycardia can be described as three or more consecutive PVCs.

Some people don't experience any symptoms whatsoever Some experience palpitations, which could feel like the heart beating faster or slower. Other signs include fatigue, dizziness, or a feeling that you're unwell.

Many people with occasional PVCs do not require treatment. If a patient is experiencing frequent episodes, a doctor might recommend a change in the diet or lifestyle. For instance, limiting caffeine, stress, and alcohol. They may also prescribe medication like beta-blockers and calcium channel blockers that can reduce the heart rate and lower blood pressure.

Doctors will ask the patient about their medical history and conduct an examination to check on their general health. They may also employ an electrocardiogram (ECG) to take an image of the heart's electrical activity, or a Holter monitor, which is worn for longer time periods and monitors the heart's rhythms over time. Doctors may request blood tests in some instances to determine if there are electrolyte imbalances or toxic effects of drugs.

Occasionally, a pvc doctor will refer a patient to a specialist in heart rhythm problems, or an electrophysiologist, to conduct a further examination. This doctor can confirm the diagnosis of PVCs and determine if they are benign or malignant.

PVCs are quite common and don't usually cause any issues, unless they happen frequently over a long time. This can cause weakening of the heart muscle, or a condition known as pvc-induced cardiomyopathy. This is more prevalent in older adults or those suffering from heart disease. It can also happen in healthy people with an uninvolved heart, however this is more likely for those who exercise regularly. This is not a serious condition, but you should inform your doctor if symptoms such as fainting or fatigue occur.

Treatment

PVCs are not harmful and do not cause any symptoms in the majority of people. They don't require treatment. But those who do experience a sensation like their heart has skipped an beat or is racing, it's important to consult a physician as soon as possible.

A cardiologist will start by interviewing you and doing physical examination, and listening to your heart with a stethoscope for any irregular heartbeats. You will also undergo an electrocardiogram, which records the electrical signals of your heart to determine any arrhythmias. If an arrhythmia has been identified then an portable ECG or 24-hour Holter monitor is required to document the abnormal rhythm for longer durations of time. These devices can assist doctors determine if you suffer from PVCs and their causes like an imbalance in electrolytes, toxicity of drugs or other factors.

An echocardiogram, also known as an ultrasound of your heart, can be ordered to assess whether your heart is in good health and look for any indications of structural issues which could cause PVCs. You could also be asked to undergo stress tests to find out the response of your heart to exercise. Exercise can increase the frequency of pvcs. You can also take blood tests to determine your thyroid hormone as well as potassium, magnesium and other hormones to see whether they're low. This could cause PVCs.

After your doctor has determined that you have PVCs and has eliminated any serious diseases, the decision of how to treat them will be based on the degree to which they're affecting your life and the frequency at which they occur. If they only occur occasionally and don't cause any symptoms, your doctor is unlikely to prescribe any medication that will reduce their frequency or severity.

If you have frequent PVCs that can trigger palpitations or other symptoms like feeling lightheaded or fainting, your doctor may prescribe medication such as beta blockers and calcium channel blockers. Changes in lifestyle, like cutting down on smoking, caffeine and stress levels that are excessive can reduce the frequency of these abnormal pulses.

Prevention

There are people who do not experience symptoms at all from PVCs, or feel heart palpitations (irregular heartbeats) that may feel like "skipped" beats or a fluttering sensation in the chest. These episodes can create feelings of fullness or pressure, or they can make you feel faint. These episodes happen because the heart is not pumping as efficiently as it normally does. The frequent PVCs increase a person's risk of developing dilated Cardiomyopathy, a condition where the heart enlarges and becomes ineffective at pump blood.

PVCs are usually caused by changes in body chemical balance. They can be caused by the release of thyroid and adrenaline hormones, and drinking caffeine or alcohol. Stress or excess weight and an insufficient amount of exercise can trigger these symptoms.

Certain people find that a change in their diet helps to reduce their PVCs. They can, for instance, avoid foods that contain preservatives which can disrupt the heart rhythm. These include disodium guanylate and diazole, and disodium inosinate sodium (E282-283). Eat more fruits and veggies to ensure that you get sufficient magnesium.

Regular health checks are important, including yearly physicals. These tests can help identify any underlying heart conditions that could be the cause of your PVCs. It is also recommended to refrain from smoking and adhere to a healthy diet plan. This could increase the frequency of episodes.

A survey of 14 regular hospital wards found that healthcare workers were generally aware of preventive measures to avoid the infection caused by vascular catheters, but their self-assessment of compliance to these procedures was not high. Compliance improved following a feedback intervention, but was still low on a few of the wards that were surveyed. This suggests that training is required on how to implement preventive measures, and those wards that are not than compliant should be targeted for monitoring of infection. This information can be used to help in the implementation of quality improvement initiatives for these wards. This will likely require further education and training for staff. It will also be important to ensure that the right materials for implementing the preventive measures are readily available.

Symptoms

Premature ventricular contractions can cause your heart to skip beats or to flutter. These arrhythmias may be harmless or they can be the sign of heart problems.

In healthy individuals, PVCs that occur occasionally are not a problem. They generally disappear on their own. But if you have many of them, they may cause dizziness or weakness. If you're concerned about them, consult your doctor about the symptoms. You may need to give your medical history and they may also conduct an examination of the body to determine the cause. They'll likely also need to do an electrocardiogram (ECG or EKG) or other tests.

An ECG is a simple test that will allow your doctor to see the signal from your heartbeat as it moves through your heart in the course of a brief time. The test will show if you have PVCs. Your doctor might also suggest a Holter monitor that records your heartbeat for a longer period of time. These can help differentiate PVCs from other arrhythmias which cause heart palpitations. You can wear an event monitor, a handheld device which keeps track of your heart's rhythm for 30 days.

Other heart tests may be required, depending on the cause of your PVCs. A cardiologist may check your blood pressure or conduct an echocardiogram (ultrasound of the door doctor heart). These tests can tell whether you are suffering from an issue like heart failure or mitral valve prolapse or cardiomyopathy.

Your doctor may also be required to run a blood test to see what is wrong with your electrolytes, like low potassium or high calcium levels. This could indicate that you have PVCs or another condition such as anemia or anxiety disorders.

You may be referred an electrophysiologist who is able to treat abnormal heart rhythms. If you have heart disease that is structural the specialist may have to do other tests, like an MRI or CT scan of your chest. These tests can tell whether you've suffered damage to your heart and how serious it is. In some cases doctors may suggest an implanted pacemaker to treat the condition that causes the PVCs.
