Why It's Important to See a Doctor

Premature ventricular contractions (PVCs), are a type of irregular heartbeats. These extra beats aren't usually hazardous, and they could go away by themselves.

Doctors will listen to your heartbeat, and check other vitals signs. They might order an Holter Monitor that captures the electrical impulses of your heart over a period of between 24 and 48 hours. They can also order blood tests to check 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 causes the next heartbeat to be delayed, causing a feeling like racing or skipped beats. PVCs may occur alone, or in repeated patterns. Two consecutive PVCs are referred to as doublets, while three or more consecutive PVCs constitute ventricular tachycardia (VT).

Some people are not experiencing any symptoms, while others experience palpitations. This can feel like a pounding heartbeat or a rapid heartbeat. Other symptoms that are common are fatigue, dizziness or a sensation of being unwell.

Many people who have occasional PVCs don't require any treatment. If a patient has frequent episodes, a physician might recommend a change in diet or lifestyle. For example, limiting caffeine or stress, as well as alcohol. They can prescribe medications such as beta-blockers and calcium channel blockers that can lower blood pressure and slow down the heart rate.

Doctors will inquire about the patient's medical history and conduct a physical exam to check their general health. They may also use an electrocardiogram (ECG) to take a snapshot of the heart's electrical activity, or a Holter monitor which is worn for longer durations and monitors the heart's rhythms over time. Doctors may require blood tests in some instances to look for imbalances in electrolytes or toxic effects of drugs.

Sometimes, a pvc physician will refer someone to a specialist for Window Screen Replacement heart rhythm problems, or an electrophysiologist, to conduct a further examination. This specialist can confirm the diagnosis of PVCs and determine whether they are benign or not.

PVCs are frequent and usually don't cause any issues, unless they occur frequently over a long period of time. This can cause a weakening in the heart muscle or a condition known as pvc-induced cardiomyopathy. This is most common in people who are older or those with some form of heart disease. It can also happen in healthy people with a normal heart, although it is more likely to occur in those who exercise regularly. Most of the time, this isn't an issue that is serious, but it is important to consult your doctor if you experience symptoms like fainting or fatigue.

Treatment

PVCs aren't harmful or cause symptoms in a lot of people. They do not require treatment. However, for those who do experience a sensation like your heart is lagging an beat or is racing, it's crucial to consult a physician as soon as you can.

A cardiologist begins by conducting an interview and then perform a physical examination, and listening to your heart with an stethoscope to detect any irregular beats. You'll also get an electrocardiogram (ECG) performed, which will record the electrical signals in your heart and identify any arrhythmias. If an arrhythmia is detected, an portable ECG or 24-hour Holter monitor is required to record the abnormal rhythm for longer periods of time. These devices will assist doctors determine whether you have PVCs and the underlying cause for them, like an electrolyte imbalance, drug toxicities, or other causes.

You might be required to undergo an echocardiogram (an ultrasound of your heart) to determine the health of your heart is in good shape and to check for structural issues that could cause PVCs. You may also undergo an exercise test to determine how your heart reacts to physical activity can increase the frequency of your 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 can lead to PVCs.

Once your doctor has confirmed that you suffer from PVCs and has eliminated any serious illness, the decision on how to treat them will be contingent on how much they're impacting your life and how frequently they occur. If they occur only occasionally and don't trigger any symptoms, it's unlikely your doctor will suggest any medication to lessen the frequency or severity of them.

If you are experiencing frequent PVCs that can trigger pulses or other symptoms, such as feeling light-headed or fainting, your doctor might prescribe medications like beta blockers and calcium channel blockers. Changes in your lifestyle, like cutting down on smoking, caffeine, and excessive stress can also reduce the frequency of these irregular pulses.

The following is a list of preventatives.

There are people who do not experience symptoms at all from PVCs, or feel heart palpitations (irregular heartbeats) that can appear as "skipped" beats or fluttering in the chest. These episodes can trigger feelings of fullness or pressure, or make you feel faint. These episodes are caused by the heart is not pumping as efficiently as it normally does. The frequent PVCs increase the risk of developing dilated cardiomyopathy. a condition where the heart expands and is not able to pump blood.

PVCs are often caused by changes in body chemical chemistry. These include the release of thyroid and adrenaline hormones, in addition to drinking alcohol or caffeine. Lack of exercise can also trigger these episodes like stress or excessive weight.

Certain people find that a change in their diet can reduce their PVCs. They can, for example avoid foods that contain preservatives that can disrupt the heart rhythm. These include disodium guanylate and diazole, and disodium Inosinate Sodium (E282-283). Eat more fruits and veggies to get enough magnesium.

Regular health checks are essential and include annual physicals. These tests can help identify any heart issues that could be causing your PVCs. It is also recommended to avoid smoking and follow an appropriate diet program. This could increase the frequency of episodes.

A survey of healthcare staff on 14 wards of a normal hospital revealed that they were aware of the preventive measures for vascular catheter-related infections however, their self-assessment of compliance with these guidelines was low. Compliance improved following an intervention to improve feedback however it was still very low on a few of the wards surveyed. This suggests that education is needed on how to implement preventive measures, and that wards that are less conforming should be targeted for infection monitoring. These data can be used to inform quality improvement initiatives in these wards. This could involve further education and training for personnel. It will also be necessary to ensure that the appropriate tools to implement the preventive measures are readily available.

Symptoms

Involuntary ventricular contractions that are premature can cause your heartbeat to skip or flutter. These arrhythmias can be harmless or they may be the sign of heart problems.

In healthy individuals, occasional PVCs aren't a problem, and they generally disappear on their own. However, if you suffer from several of them, they can lead to dizziness or weakness. Consult your doctor if you are worried. They may have to identify the issue by taking a medical history and conducting a physical exam. They might also conduct an electrocardiogram, or other tests.

An ECG is a simple test that lets your health care provider see the signal from your heartbeat moving through your heart over a short period of time. If you have PVCs, they'll be visible on the test. Your doctor may also suggest the use of a Holter monitor that tracks your heartbeat for a longer period of time. These tests can help distinguish PVCs from arrhythmias causing heart palpitations. You could also carry a device that records your heart rate over a period of 30 days, referred to as an event monitor.

Other tests for your heart might be required, based on the cause of your PVCs. A cardiologist may check your blood pressure or window frame repair perform an echocardiogram (ultrasound of the heart). These tests can determine whether you have an illness such as heart failure, 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 like low potassium or high calcium levels. This can be an indication of PVCs or other conditions that could cause them, including anemia and anxiety disorders.

You could be directed to an electrophysiologist, a specialist who specializes in treating abnormal heart rhythms. If you have structural heart disease the specialist may have to conduct additional tests, like an MRI or CT scan of your chest. These tests can determine whether you've suffered damage to your heart and how severe it is. In some instances, the specialist might suggest a pacemaker or ICD to treat the underlying issue causing your PVCs.
