Why It's Important to See a Doctor

Premature ventricular contractions (PVCs) are a form of irregular heartbeat. These extra beats are usually not hazardous, and they could disappear by themselves.

Doctors will monitor your heartbeat and look for other vital signs. They may also order an Holter Monitor which records the electrical impulses of your heart over a time of 24 to 48 hours. They can also order blood tests to assess the levels of electrolytes and thyroid hormones.





Diagnosis

PVCs happen when electrical impulses from the heart's lower chambers ventricles, or lower chambers, fail to pass through a structure called the SA node. This causes the heartbeat to be delayed, causing the feeling of fluttering or skipped beats in the chest. PVCs can occur 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.

While some people don't show any symptoms Some experience palpitations, which can feel like the heart beating faster or slower. Other signs are dizziness, fatigue or a feeling of being unwell.

Many people with occasional PVCs do not require treatment. If a person experiences frequent episodes, doctors could suggest a change to diet or lifestyle, such as limiting caffeine, alcohol and stress. They may also prescribe medication like beta-blockers and calcium channel blockers which can lower the heart rate and lower blood pressure.

Doctors will inquire about the patient's medical history and perform a physical examination to check their general health. They may also employ an electrocardiogram (ECG) to get 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. Doctors may order blood tests in some instances to check for electrolyte imbalances or toxic substances in the body.

Sometimes, a pvc physician will refer someone to a specialist in heart rhythm issues, or an electrophysiologist, for further evaluation. The doctor can confirm the diagnosis of PVCs and determine if they are benign or malignant.

PVCs are quite common and rarely cause any problems unless they happen frequently over a long period of time. This could lead to a weakening in the heart muscle or a condition known as pvc-induced cardiomyopathy. This is most prevalent in older people or those suffering from some type of heart disease. It can also occur in healthy people with a normal heart, although this is more likely in those who exercise regularly. It's not a serious issue, but you should tell your doctor if symptoms such as fainting or fatigue occur.

Treatment

For many people, occasional PVCs may not cause any symptoms or are harmless and require no treatment. If you notice that your heart is racing or not making the beat, it's best to seek out a physician immediately.

A cardiologist will start by interviewing you and performing a a physical exam, listening to your heart with the stethoscope to look for irregular beats. windows doctor 'll also undergo an electrocardiogram that records the electrical signals of your heart to detect any arrhythmias. If an arrhythmia is identified then a 24-hour Holter monitor or another portable ECG is required to record the irregular rhythm for longer periods of time. These devices can help doctors determine if you suffer from PVCs and the reason for them, such as an imbalance in electrolytes, toxicity of drugs or other causes.

An echocardiogram, or an ultrasound of your heart, may be ordered to determine if your heart is healthy and check for signs of structural problems that can lead to PVCs. You may also be asked to take an exercise test to assess how your heart reacts to exercise. Physical activity can increase the frequency of pvcs. You can also take blood tests to determine your thyroid hormone, magnesium, potassium, and other hormones to determine whether they're insufficient. This can lead to PVCs.

If your doctor confirms that you have PVCs, and has ruled any serious illnesses out, the decision to treat them depends on how they impact your life and how often they occur. If they happen only on occasion and don't cause any symptoms, it's unlikely that your doctor will prescribe any medication to reduce their frequency or severity.

If, however, you suffer from frequent PVCs that trigger palpitations and other symptoms, like lightheadedness or feeling like you're going to faint, your physician may suggest medications for you, such as beta blockers or calcium channel blockers. Changing your lifestyle to avoid triggers, such as caffeine, smoking and excessive stress, can help lower the number of occurrences of these unusual pulses.

Prevention

There are people who do not experience symptoms whatsoever from PVCs or experience heart palpitations (irregular heartbeats) that can feel like "skipped" beats or fluttering in the chest. These episodes can cause an feeling of pressure or fullness, or they can make you feel faint. These episodes occur because the heart isn't functioning as efficiently as it should. Frequent PVCs increase a person's risk of developing dilated cardiomyopathy, a condition where the heart gets larger and is not able to pump blood.

PVCs often are caused by changes in body chemical chemistry. This includes the release of thyroid and adrenaline hormones, in addition to drinking caffeine or alcohol. Stress or excess weight or the absence of exercise can trigger these symptoms.

Some people find that changing their diet can reduce the number of PVCs. For instance, they can avoid foods that contain preservatives that can cause disturbances in the heartbeat, for example disodium Guanylate (E621), disodium inosinate (E627) diazole sodium (E282-283). Consume more fruits and vegetables to get sufficient magnesium.

It is important to get regular health checks, including annual physicals and laboratory tests. These can help diagnose any underlying heart conditions that could be causing your PVCs. Also, you should adhere to an eat-healthy diet and refrain from smoking, which can increase the frequency of your episodes.

A survey of healthcare professionals on 14 normal hospital wards found that they were mostly aware of the preventive measures to avoid infections caused by vascular catheters however, their self-assessment of compliance with these practices was low. Compliance improved following feedback interventions, but was still low on some of the observed wards. This suggests that education on the best ways to implement preventive measures is essential, and that those wards that are not complying should be targeted for infection surveillance. These data can be used to guide quality improvement initiatives in these wards. This will most likely require additional education and training of personnel. It is also necessary to ensure that the right tools for implementing the preventive measures are in place.

Signs and symptoms

Premature ventricular contractions can cause your heart to skip beats or be fluttering. These arrhythmias can be harmless, or they could indicate you have heart issues that are serious.

In healthy people, sporadic PVCs aren't a problem and they usually disappear by themselves. If you have many of them, they can cause dizziness or weakness. If you're concerned you might be experiencing dizziness or weakness, talk to your doctor about them. You might need to provide your medical history and they might also perform an examination of the body to identify the issue. They may also want to perform an electrocardiogram or other tests.

An ECG is a simple test that allows your health care provider detect the signal of your heartbeat moving through your heart for a short period of time. The test will reveal whether you have PVCs. Your doctor may also suggest the use of 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 may also be wearing a device that records your heart rate over a period of 30 days, referred to as an event monitor.

Other tests for the heart may be needed, depending on the cause of your PVCs. For instance an cardiologist may test your blood pressure and perform an ultrasound of your heart (echocardiogram). These can help find whether you suffer from a condition that may be causing your PVCs like cardiomyopathy, mitral valve prolapse or heart failure.

Your doctor may also be required to run an analysis of your blood to determine the issue with your electrolytes. For instance, you may have low potassium levels or high levels of calcium. This can be a sign of PVCs or other conditions that can cause them, such as anemia and anxiety disorders.

You could be referred to an electrophysiologist who is able to treat abnormal heart rhythms. If you have structural heart disease the doctor may need to perform additional 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 a pacemaker to treat the issue that is causing the PVCs.
