Why It's Important to See a Doctor
Premature ventricular contractions (PVCs), are a kind of irregular heartbeats. These extra beats are usually not dangerous, and they can go away on their own.
Doctors will monitor your heartbeat and also check other vitals indicators. They might recommend an Holter monitor which records your heart's electrical impulses over the course of 24 hours. They may also order blood tests to check your electrolyte levels and thyroid hormones.
Diagnosis
PVCs are caused by electrical impulses that misfire through the SA node, which is a structure in the lower chambers of the heart. This delay the next heartbeat which can cause the feeling of fluttering or skipped beats in the chest. PVCs can occur in one pattern or in repeated patterns. Two consecutive PVCs are referred to as doublets, while three or more consecutive PVCs are referred to as the condition known as ventricular tachycardia (VT).
While some people don't show any symptoms at all Some experience palpitations, which could feel like an irregular heartbeat or a pounding. Other common symptoms are tiredness or dizziness, or a feeling of being unwell.
Many people who experience occasional PVCs do not require any treatment. If a patient has frequent episodes, a doctor might suggest a change in diet or lifestyle. For example, limiting caffeine and stress as well as alcohol. They may also prescribe medications such as beta-blockers or calcium channel blockers that can reduce the heart rate and lower blood pressure.
Doctors will inquire about their medical history and conduct an examination of the body to check on 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 time periods and monitors the heart's rhythms over time. Doctors may request blood tests in some cases to look for imbalances in electrolytes or toxic effects of drugs.
Occasionally, a pvc doctor will refer someone to a specialist for heart rhythm issues, or an electrophysiologist, for further evaluation. The doctor will confirm the diagnosis of PVCs and determine if they are benign or not.
PVCs are everywhere and are not usually harmful unless they are used frequently or for a long time. This can lead to a weakening of the heart muscle, or a condition known as pvc-induced cardiomyopathy. This is most common in older people or those with any form of heart disease. It can also happen to healthy people who have normal, normal hearts. However, it's more prevalent in people who exercise regularly. It's not an issue to worry about but it's important to tell your doctor if you experience symptoms like fainting or fatigue.
Treatment
For many people, sporadic PVCs aren't likely to cause symptoms or are harmless and need no treatment. But, for those who do experience a sensation like your heart is lagging the beat or is racing, it's vital to speak to a doctor as soon as possible.
A cardiologist will begin by interviewing you and performing a physical examination, and monitoring your heart using a stethoscope for any irregular beats. You'll also undergo an electrocardiogram, which records the electrical signals of your heart, allowing you to identify any arrhythmias. If an arrhythmia has been discovered then the use of a portable ECG or a 24-hour Holter monitor will be required to capture the abnormal rhythm for longer durations of time. These devices can help doctors determine if you suffer from PVCs, and their cause which could be due to an imbalance in electrolytes, drug toxicity or other factors.
An echocardiogram, an ultrasound of your heart, could be ordered to assess whether your heart is healthy and look for any signs of structural problems which could cause PVCs. You may also undergo a stress test to see how your heart reacts to exercise, as physical activity can increase the frequency of your PVCs. You can also have blood tests to test your thyroid hormone as well as potassium, magnesium and other hormones to determine if they're too low. This can lead to PVCs.
If your doctor has confirmed that you have PVCs, and has ruled any serious illnesses out, the treatment you choose to take will depend on how they affect your life and how frequently they occur. If they occur only occasionally and don't cause any symptoms, it's unlikely your doctor will suggest any medication to decrease the frequency or severity of them.
However, if you have frequent PVCs that cause heart palpitations, as well as other symptoms such as feeling lightheaded or like you're about to faint, your doctor might suggest medication like beta blockers or calcium channel blockers. Making changes to your lifestyle in order to avoid triggers, like smoking, caffeine, and excessive stress, can aid in reducing the frequency of instances of these abnormal pulses.
The following is a list with preventions.
PVCs can cause no symptoms or heart palpitations that can feel like "skipped beats" or flutterings in the chest. These episodes can cause feelings of fullness or pressure, or they can make you feel faint. These episodes result from the heart not pumping as effectively as it should. Frequent PVCs increase the chance of developing dilated cardiomyopathy, a condition in which the heart expands and becomes ineffective at pump blood.
PVCs are usually caused by changes in the body's chemistry. This includes the release of adrenaline and thyroid hormones, as well as drinking caffeine or alcohol. Stress or excess weight or the absence of exercise can trigger these episodes.
Some people can find that a change in their diet helps reduce their PVCs. For instance, they can, avoid foods that are preservative-laden, which can cause a disturbance of the heart rhythm. These include disodium guanylate, diazole, and disodium Inosinate sodium (E282-283). You can also consume more fruits and vegetables to ensure they're getting sufficient magnesium and potassium.
Regular health checks are important, including yearly physicals. They can aid in identifying any underlying heart conditions which could be causing your PVCs. It is also recommended to refrain from smoking and adhere to the healthy eating plan. This can increase the frequency of episodes.
A survey of 14 normal hospital wards showed that healthcare staff were generally aware of preventive measures against the infection caused by vascular catheters, but their self-assessment of compliance to these procedures was not high. Compliance improved following an intervention to improve feedback however it was still very low on some of the wards that were surveyed. This suggests that education is required to implement preventive measures and those wards that are not than compliant should be targeted for monitoring of infection. This information can then be used to guide the implementation of additional quality improvement initiatives for these wards. This will likely require more education and training for personnel. It will also involve making sure that the appropriate materials are in place for the implementing of the preventive measures.

Premature ventricular contractions can cause your heartbeat to skip or to flutter. These arrhythmias could be normal, or they could indicate that you are suffering from serious heart issues.
In healthy people, PVCs that occur occasionally are not an issue. They typically disappear on their own. If you're suffering from a lot of them, they can cause dizziness or weakness. Speak to your doctor if concerned. You might need to provide your medical history and they might also perform an examination to determine the cause. They may also want to conduct an electrocardiogram, or other tests.
A quick ECG test lets your doctor see the pulse of your heart moving through your body for a a short period of time. The test will reveal if you have PVCs. Your doctor might also want to conduct an overnight or 24-hour Holter monitor which monitors your heartbeat for longer durations of time. These tests can help differentiate PVCs from arrhythmias that cause heart palpitations. You may also wear a portable device that can record your heart's rhythm over a period of 30 days, referred to as an event monitor.
Other tests for your heart might be required, depending on the cause of your PVCs. A cardiologist will test your blood pressure or perform an echocardiogram (ultrasound of the heart). These can help find if you have a condition that may be causing your PVCs like cardiomyopathy, mitral valve prolapse or heart failure.
Your doctor may also be required to conduct an examination of your blood to determine what is wrong in your electrolytes, for example, low potassium levels or high calcium levels. This could be a sign that you have PVCs or another condition such as anemia or anxiety disorders.
You could be referred to an electrophysiologist who treats abnormal heart rhythms. The specialist might need to conduct other tests if you have heart problems that are structural, such as an CT or MRI scan of your chest. These tests can tell whether you've damaged your heart, and how serious it is. In some cases, the doctor might suggest the use of a pacemaker or ICD to treat the condition that is creating your PVCs.
