Why It's Important to See a Doctor

Premature ventricular contractions (PVCs) are a type of irregular heartbeat. These extra beats are usually not dangerous and may disappear on their own.

To determine PVC doctors listen to your heartbeat and look for other vital signs. They may order a Holter monitor, a device that records the electrical impulses your heart produces over 24-48 hours. They can also order blood tests to determine your electrolyte levels and thyroid hormones.

Diagnosis

PVCs are caused by electrical impulses that reverberate through the SA node, a structure in the lower chambers of the heart. This delays the next heartbeat, causing an experience of skipped beats or fluttering in the chest. PVCs can occur in isolation or in repeated patterns. Doublets are two consecutive PVCs. Ventricular tachycardia can be described as three or more consecutive ones.

Some people do not experience any symptoms, but others experience palpitations. It could be an unsteady heartbeat or a rapid heartbeat. Other typical symptoms include fatigue or dizziness, or a feeling of being sick.

Many people who have occasional PVCs don't need any treatment. If a person experiences frequent episodes, doctors may recommend a change in diet or lifestyle, such as limiting alcohol, caffeine and stress. They might prescribe beta-blockers or calcium channel blockers that lower blood pressure and slow down the heart rate.

Doctors will inquire about their medical history and perform an examination of the body to determine their general health. They may also utilize a Holter monitor to record the heart's rhythms over longer durations, or an electrocardiogram, which captures a picture of the electrical activity of the heart. In certain cases doctors may request blood tests to check for an electrolyte imbalance or toxic effects from drugs.

A pvc doctor may refer the patient to an electrophysiologist, or a specialist in heart rhythm disorders for further evaluation. This specialist can confirm the diagnosis of PVCs and determine if they are benign or not.

PVCs are fairly common and rarely cause any issues, except when they are frequent over a long period of time. This can lead to a weakened in the heart muscle, or a condition known as pvc-induced cardiac myopathy. This is most common in people who are older or those suffering from any form of heart disease. It can also occur in healthy people with normal heart function, but 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, sporadic PVCs aren't likely to cause symptoms or are harmless and require no treatment. However, for those who do experience a sensation like their heart has skipped an beat or is racing, it's crucial to see a doctor immediately.

A cardiologist begins by interviewing you and performing a physical examination, and monitoring your heart using the stethoscope to look for irregular heartbeats. Additionally, you will have an electrocardiogram (ECG) done that records the electrical impulses that occur in your heart and detect any arrhythmias. If an arrhythmia has been detected it is recommended to use the use of a portable ECG or 24-hour Holter monitor is required to document the irregular rhythm for longer periods of time. These devices will help doctors determine whether you have PVCs and the underlying cause for them, such as an electrolyte imbalance, drug toxicities, or any other cause.

You might be requested to undergo an echocardiogram (an ultrasound of your heart) to determine the health of your heart is good and to look for structural problems that could cause PVCs. You may also be required to undergo a stress test in order to assess how your heart reacts to exercise. Physical activity can increase the frequency of PVCs. You can also have blood tests to assess your magnesium, potassium and thyroid hormone levels to find out whether they are low, which can contribute to the development of PVCs.

Once your doctor has confirmed that you're suffering from PVCs and has eliminated any serious diseases, the decision on whether or not to treat them will depend on the extent to which they impact your life and how often they occur. If they only occur occasionally and do not cause symptoms, your doctor is unlikely to recommend any treatment to reduce their frequency or severity.

If you are experiencing frequent PVCs, which can cause palpitations or other symptoms such as feeling light-headed or fainting, your doctor may prescribe medications such as beta blockers and calcium channel blockers. Changing your lifestyle to avoid triggers, like caffeine, smoking and excessive stress, can also aid in reducing the frequency of occurrences of these abnormal pulses.

The following is a list with preventions.

There are people who do not experience symptoms whatsoever from PVCs or experience heart palpitations (irregular heartbeats) that can appear as "skipped" beats or a fluttering sensation in the chest. Sometimes, these episodes can cause the chest to feel full or swollen in the chest, and other occasions, they may make a person feel faint. These episodes are caused by the heart not pumping as well as it should. PVCs are linked to an increased risk of developing dilated cardiac myopathy. This is a condition where the heart becomes enlarged and in a position to not pump blood.

PVCs are often caused by changes in the body's chemistry. This includes the release of adrenaline and thyroid hormones, as well as drinking alcohol or caffeine. Inactivity can trigger these symptoms like stress or excess weight.

Certain people find that changing their diet can reduce the number of PVCs. For instance, they can avoid foods that are preservative-laden, which can cause a disturbance of the heart rhythm. These include disodium guanylate and diazole, and disodium Inosinate Sodium (E282-283). They can also consume more fruits and vegetables to ensure they are getting enough magnesium and potassium.

It is important to get regular health checks, which include yearly physicals and lab tests. They can aid in identifying any heart issues that could be the cause of your PVCs. Also, you should not smoke and adhere to the healthy eating plan. This can increase the frequency of episodes.

A survey of healthcare workers on 14 normal hospital wards found that they were mostly aware of the preventive measures to avoid vascular catheter-associated infections However, their self-assessed compliance with these guidelines was low. The compliance improved following a feedback intervention, but was still low on some of the observed wards. This suggests that education on the best ways to implement preventive measures is necessary and that wards which are less compliant should be targeted for infection surveillance. These data can be used to guide quality improvement initiatives in these wards. This will likely require more education and training for personnel. It will also involve making sure that the correct tools are available for implementing of the preventive measures.

Symptoms

The premature contraction of the ventricular muscle can cause your heartbeat to skip beats or to flutter. These arrhythmias may be harmless, or they could be a sign that you have serious heart problems.

In healthy people, occasional PVCs aren't an issue and they generally disappear by themselves. But if you have a lot of them, they could lead to dizziness or weakness. If you're concerned about them, consult your doctor about them. You might need to provide a medical history, and they may also conduct an examination to identify the issue. They might also need to conduct an electrocardiogram or other tests.

An ECG is a simple test that lets your health care provider observe the signal generated by your heartbeat as it moves through your heart in a short duration. The test will reveal if you have PVCs. Your doctor might also want to do an overnight or 24-hour Holter monitor that records your heartbeat for longer periods of time. This can help distinguish PVCs from other types of arrhythmias that cause heart palpitations. You could also be wearing a device that records your heart rate over 30 days, called an event monitor.

Other tests for the heart may be required, based on the reason for your PVCs. For instance, a cardiologist might check your blood pressure and do an ultrasound of the heart (echocardiogram). These tests can determine whether you are suffering from an illness like heart failure or mitral valve prolapse or cardiomyopathy.


Your doctor may also have to run an analysis of your blood to determine what's wrong with your electrolytes such as low potassium or high calcium levels. This could be a sign that you have PVCs, or another problem such as anemia, or anxiety disorders.

You may be referred to an electrophysiologist who treats abnormal heart rhythms. If door doctor have heart disease that is structural the specialist may have to do other tests, such as an MRI or CT scan of your chest. These tests will determine if your heart is damaged and the severity of the damage. In some cases, the specialist might suggest a pacemaker or ICD to treat the condition that is the cause of your PVCs.
