Why It's Important to See a Doctor

Premature ventricular contracts (PVCs) are a form of irregular heartbeats. Read Far more aren't usually dangerous, and they can disappear by themselves.

To diagnose PVC doctors listen to your heartbeat and check other vital indicators. They might order an Holter Monitor that captures the electrical impulses of your heart over a period of between 24 and 48 hours. They may also order blood tests to determine your thyroid hormones and electrolyte levels.

Diagnosis

PVCs are caused by electrical impulses from the heart's lower chambers, or ventricles, misfire through a structure referred to as the SA node. This causes the next heartbeat to delay, which can cause an experience similar to racing or skipped beats. PVCs can occur in one pattern or in repeated patterns. Doublets are two consecutive PVCs. Ventricular tachycardia can be described as three or more consecutive PVCs.

Some people are not experiencing any symptoms, while others experience palpitations. It can be felt as the sound of a beating heart or a slurred heartbeat. Other symptoms include dizziness, fatigue, or a feeling that you're unwell.

Many people who suffer from occasional PVCs do not require any treatment. If someone is experiencing frequent episodes, doctors may suggest a change in lifestyle or diet, such as limiting caffeine, alcohol and stress. They may also prescribe medications like calcium channel blockers or beta-blockers that can reduce the heart rate and lower blood pressure.

Doctors will ask the patient about their medical history, and then perform an examination to assess their general health. They may also use an electrocardiogram (ECG) to get a snapshot of the heart's electrical activity or a Holter monitor, which is worn for longer periods and records the heart's rhythms over time. Doctors may require blood tests in some instances to check for electrolyte imbalances or toxic substances in the body.

A pvc physician may refer a patient to an electrophysiologist or 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 can be found everywhere and are generally not harmful unless they are used frequently or for long periods of time. This can cause a weakening in the heart muscle, or a condition known as pvc-induced cardiomyopathy. This is most prevalent in older people, or those who have some type of heart disease. It can also happen in healthy people with an uninvolved heart, however this is more likely for those who exercise regularly. It is not a major problem, but it is important to consult your physician if you notice symptoms like fatigue or fainting occur.

Treatment

PVCs are not harmful and do not cause symptoms in many people. They do not require treatment. But, for those who do experience a sensation like their heart has skipped an beat or is racing, it's important to speak to a doctor immediately.

A cardiologist will interview you and then perform physical examinations and listen to your heart through the stethoscope in order to detect any irregular heartbeats. You'll also undergo an electrocardiogram, which captures the electrical impulses of your heart, allowing you to identify any arrhythmias. If an arrhythmia is discovered, the use of a portable ECG or a 24-hour Holter monitor is required to capture the abnormal rhythm for longer durations of time. These devices will assist doctors determine if you have PVCs and the underlying cause for them, like an electrolyte imbalance, a drug toxicities, or other causes.

An echocardiogram, or an ultrasound of your heart, could be ordered to determine whether your heart is healthy and to look for indications of structural issues which could cause PVCs. You might also have a stress test to check how your heart reacts to exercise, since physical activity can increase the frequency of your pvcs. You may also undergo blood tests to determine your thyroid, potassium, and magnesium hormone levels to determine whether they are low and can cause the formation of PVCs.

After your doctor has determined that you have PVCs and has ruled out any serious illness, the decision on how to treat them will be contingent on how much they're impacting your life and the frequency at which they occur. If they only occur occasionally and do not cause any symptoms, your doctor is unlikely to recommend any treatment to decrease their frequency or severity.

If you experience frequent PVCs that trigger palpitations and other symptoms, like lightheadedness or feeling like you're about to faint, your doctor might recommend medications for you, such as beta blockers or calcium channel blockers. Changes in your lifestyle, like abstaining from smoking, caffeine and stress levels that are excessive can also decrease the frequency of these irregular pulses.

The following is a list with preventions.

PVCs can cause no symptoms or heart palpitations which may be described as "skipped beats" or flutterings in the chest. Sometimes, these episodes trigger a fullness or pressure in the chest, and other times they can cause a person to feel faint. These episodes happen because the heart is not pumping as effectively as normal. Regular PVCs increase the risk of developing dilated cardiomyopathy, a condition wherein the heart gets larger and is not able to pump blood.

PVCs are often caused by changes in the body's chemical. This includes the release of thyroid hormones and adrenaline and alcohol consumption or caffeine. Stress or excess weight, as well as the absence of exercise can trigger these episodes.

Certain people find that changing their diet can reduce the number of PVCs. They can, for example, avoid foods that contain preservatives which can disrupt the heart rhythm. These include disodium guanylate and disodium Inosinate, and diazole sodium (E282-283). Consume more fruits and vegetables to get sufficient magnesium.

Regular health checks are crucial as are annual physicals. These can help diagnose any underlying heart conditions which 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 that could be used to treat vascular catheter-associated infections however, their self-assessment of compliance with these guidelines was low. The compliance improved following a feedback intervention however, it was still low on a few of the wards that were surveyed. This suggests that training is needed on how to implement preventive measures and that wards that are less compliant need to be targeted for infection monitoring. These data can be used to guide quality improvement initiatives in these wards. This will likely require more education and training for staff. It will also be important to ensure that the appropriate materials for implementing the preventive measures are available.

Signs and symptoms

The premature contraction of the ventricular muscle can cause your heartbeat to skip or be fluttering. These arrhythmias can be normal, or they could indicate you have serious heart problems.

In healthy individuals, occasional PVCs aren't a problem, and they usually go away by themselves. If you've got a lot of them, it could cause dizziness or weakening. Speak to your doctor if concerned. They may have to identify the problem by taking a medical history and giving you an examination. They'll also probably want to do an electrocardiogram (ECG or EKG) or other tests.

An ECG is a test that's quick that will allow your doctor to detect the signal of your heartbeat moving through your heart for a short time. If you have PVCs, they'll show up in the test. Your doctor may also suggest the use of a Holter monitor that tracks your heartbeat over a longer amount of time. These tests can help distinguish PVCs from arrhythmias that cause heart palpitations. You can wear an event monitor, a handheld device that keeps track of your heart's rhythm for 30 days.

Other tests for your heart might be required, based on the cause of your PVCs. For instance a cardiologist could check your blood pressure and perform an ultrasound of your heart (echocardiogram). These tests can reveal whether you suffer from a issue that could be causing your PVCs, such as mitral valve prolapse, cardiomyopathy or heart failure.

Your doctor may also be required to run an analysis of your blood to determine the problem with electrolytes. For example, low potassium or high levels of calcium. This could be a sign that you suffer from PVCs or another condition such as anemia or anxiety disorders.


You could be referred to a specialist in electrophysiology, who treats abnormal heart rhythms. This specialist may need to conduct additional tests if you have heart conditions that cause structural damage like a CT or MRI scan of your chest. These tests will help determine if your heart is damaged and how severe the damage is. In some instances doctors may suggest a pacemaker to treat the issue that causes the PVCs.
