Why It's Important to See a Doctor

Premature ventricular contracts (PVCs) are a kind of irregular heartbeats. These extra beats aren't usually risky, and they may disappear on their own.

To diagnose PVC doctors listen to your heartbeat and look for other vital signs. They may also order an Holter Monitor that records the electrical impulses generated by your heart over a span of 24 to 48 hours. They can also request blood tests for checking your thyroid hormones and electrolyte levels.

Diagnosis

PVCs happen when electrical impulses coming from the lower chambers of the heart ventricles, or lower chambers, fail to pass through a structure called the SA node. This delays the next heartbeat and causes a feeling of fluttering or skipped beats in the chest. PVCs may occur alone or in repeated patterns. Two consecutive PVCs are referred to as doublets. Three or more consecutive PVCs are referred to as the condition known as ventricular tachycardia (VT).

While some people don't have any symptoms at all Others experience heart palpitations which can feel like an irregular heartbeat or a pounding. Other symptoms that are common are fatigue and dizziness, as well as a feeling of being sick.

A lot of people who have occasional PVCs don't need any treatment. If a patient has frequent episodes, a doctor might recommend a change in the diet or lifestyle. For example restricting caffeine, stress, and alcohol. They may also prescribe medications like beta-blockers or 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 determine their general health. They can also perform an electrocardiogram (ECG) to take an image of the heart's electrical activity, or a Holter monitor, which is worn for longer time periods and records the heart's rhythms over time. In certain cases doctors may request blood tests to determine if there is an electrolyte imbalance or toxic effects from drugs.

A pvc doctor might refer the patient to an electrophysiologist, or a specialist in heart rhythm disorders for further evaluation. This doctor will confirm a diagnosis of PVCs and determine if they are benign or malignant.

PVCs are all over the place and are not usually harmful unless they are used frequently or for a long time. This can cause weakening of the heart muscle or a condition called pvc-induced cardiomyopathy. This is more prevalent in older adults or those with heart disease. It can also occur in healthy people with a normal heart, although this is more likely in those who exercise regularly. Usually, this isn't an issue that is serious however it is crucial to tell your doctor if you experience symptoms like fainting or fatigue.

Treatment

For many, occasional PVCs aren't likely to cause symptoms or require no treatment. However, for those who do experience a sensation like your heart is lagging a beat or is racing, it's crucial to speak to a doctor immediately.

A cardiologist will first interview you and perform physical examinations by listening to your heart using the stethoscope in order to detect any irregular heartbeats. You will also undergo an electrocardiogram that captures the electrical impulses of your heart to detect any arrhythmias. If an arrhythmia is found it is recommended to have a 24-hour Holter monitor or a portable ECG will be needed to capture the abnormal rhythm over longer periods of time. These devices will assist doctors determine if you suffer from PVCs and the reason behind them, such as an electrolyte imbalance or drug toxicity, or other factors.

An echocardiogram, or an ultrasound of your heart, can be ordered to assess if your heart is healthy and look for any signs of structural problems that could lead to PVCs. You may also undergo an exercise test to determine how your heart responds to exercise, since physical exercise can increase the frequency of your pvcs. You can also have blood tests to determine your thyroid, potassium, and magnesium hormone levels to find out whether they are insufficient which could contribute to the formation of PVCs.

After your doctor confirms that you have PVCs and has ruled any serious illnesses out, the decision to treat them is based on the impact they have on your life and how frequently they occur. If they only occur occasionally and do not cause symptoms then your doctor is unlikely to recommend any treatment that will decrease their frequency or severity.

However, if you have frequent PVCs that do cause heart palpitations, as well as other symptoms like lightheadedness or feeling like you're about to faint, your physician may suggest medications for you, such as beta blockers or calcium channel blockers. Altering your lifestyle to avoid triggers, such as smoking, caffeine, and excessive stress, can reduce the frequency of occurrences of these unusual pulses.

Prevention

PVCs can cause no symptoms or heart palpitations, which may feel like "skipped beats" or flutters in your chest. These episodes can create feelings of fullness or pressure, or they can make you feel faint. These episodes are caused by the heart not pumping as efficiently as it should. Frequent PVCs increase the risk of developing dilated Cardiomyopathy, a condition where the heart enlarges and becomes ineffective at pump blood.

PVCs are usually caused by changes in the body's chemical chemistry. They can be caused by the release of adrenaline and thyroid hormones, in addition to drinking caffeine or alcohol. Stress or excess weight and an insufficient amount of exercise can trigger these episodes.

Some people find that changing their diet can help reduce the amount of PVCs. They can, for example avoid foods that contain preservatives which can cause a disturbance of the heart rhythm. These include disodium guanylate, diazole, and disodium Inosinate sodium (E282-283). Eat more fruits and veggies to ensure that you get enough magnesium.

It is essential to have regular health check-ups, which include annual physicals and laboratory tests. These tests can help identify any heart-related conditions that could cause your PVCs. It is also recommended to adhere to a healthy eating plan and refrain from smoking, which can increase the frequency of your episodes.

A survey of 14 regular hospital wards revealed that healthcare workers were generally aware of preventive measures for the infection caused by vascular catheters, but their self-assessment of conformity to 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 on how to implement the preventive measures is essential and that wards which are less compliant should be targeted for infection surveillance. This information could be used to guide the implementation of additional quality improvement initiatives on these wards. It is likely that this will require additional education and training of personnel. It will also require making sure that the right materials are in place for the implementation of the preventive measures.

Signs and symptoms

Involuntary ventricular contractions that are premature can cause your heartbeat to skip or flutter. These arrhythmias can be harmless or they could be an indication of serious heart problems.

In healthy people, occasional PVCs aren't a problem and they generally disappear by themselves. If you have many of them, it could cause dizziness or weakness. Speak to your doctor if you're concerned. They may need to determine the issue by taking an history of your medical condition and giving you a physical exam. They might also conduct an electrocardiogram or other tests.

An ECG is a test that's quick that lets your health care provider detect the signal of your heartbeat as it moves through your heart for the course of a brief time. The test will determine if you have PVCs. Your doctor may also suggest a Holter monitor that records your heartbeat over a longer amount of time. They can help distinguish PVCs from other types of arrhythmias that cause heart palpitations. You can wear an event monitor, a portable device which keeps track of your heart's rhythm for 30 days.

Other heart tests may be required, 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 is responsible for your PVCs, such as mitral valve prolapse or heart failure.

the window doctor  may also need to perform tests on your blood to identify the problem with electrolytes. For instance, you may have low potassium levels or high levels of calcium. This can be an indication of PVCs or other conditions that may cause them, including anemia and anxiety disorders.

You might be referred to an electrophysiologist an expert who specializes in treating heart rhythms that are abnormal. The specialist might need to conduct other tests if you are suffering from heart problems that are structural like the 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, a specialist may recommend a pacemaker to treat the condition that is causing the PVCs.
