Why It's Important to See a Doctor

Premature ventricular contractures (PVCs) are a type of irregular heartbeats. These extra beats are usually not dangerous and can disappear on their own.

To determine PVC Doctors will listen to your heartbeat, and also check other vital signs. They may also order an Holter Monitor which records the electrical impulses generated by your heart over a time of 24 to 48 hours. They might also order blood tests to check the levels of electrolytes and thyroid hormones.

Diagnosis


PVCs happen when electrical impulses from the heart's lower chambers ventricles, or lower chambers, fail to pass through a structure referred to as the SA node. This causes the next heartbeat to delay, which can cause a feeling like racing or skipped beats. PVCs can occur in isolation, or in repeated patterns. Two consecutive PVCs are known as doublets, whereas three or more consecutive PVCs are referred to as ventricular tachycardia (VT).

While some people don't have any symptoms Some experience palpitations, which could feel like the heart beating faster or slower. Other symptoms include fatigue, dizziness, or feeling unwell.

Many people who experience occasional PVCs don't require any treatment. If someone is experiencing frequent episodes, doctors may recommend a change in the way of life or diet including a reduction in caffeine, alcohol and stress. They may also prescribe medications, such as beta-blockers and calcium channel blockers which can lower the heart rate and lower blood pressure.

Doctors will ask about the patient's medical history and conduct a physical exam to assess their general health. They may also employ an electrocardiogram (ECG) to get an image of the heart's electrical activity, or a Holter monitor that is worn for longer durations and monitors the heart's rhythms over time. In certain instances doctors may require blood tests to determine if there is an electrolyte imbalance or drug toxicity.

Sometimes, a pvc physician may refer a patient to a specialist in heart rhythm problems, or an electrophysiologist, to conduct a further examination. windowdoctor can confirm the diagnosis of PVCs and determine whether they are benign or not.

PVCs are everywhere and are generally not harmful unless they are used frequently or for long periods of time. This can cause weakening of the heart muscle or a condition called pvc-induced cardiomyopathy. It is more prevalent in older people or those suffering from heart disease. It can also occur in healthy people with normal heart function, but it is more likely to occur in those who exercise regularly. It's not an issue that is serious but it's important to speak with a doctor if you notice symptoms like fainting or fatigue.

Treatment

For many people, occasional PVCs aren't likely to cause symptoms or require no treatment. If you feel like your heart is racing or slurring the beat, it's best to consult a doctor immediately.

A cardiologist will start by interviewing you and doing physical examination, and monitoring your heart using an stethoscope to detect any irregular beats. Additionally, you will undergo an electrocardiogram, which records the electrical signals of your heart to determine any arrhythmias. If an arrhythmia is detected it is recommended to have an all-day Holter monitor or other portable ECG will be needed to capture the irregular rhythm for longer durations of time. These devices will help doctors determine if you suffer from PVCs and the reason behind them, like an electrolyte imbalance, drug toxicities, or any other cause.

An echocardiogram, or an ultrasound of your heart, may be ordered to determine whether your heart is healthy and look for any signs of structural problems which could cause PVCs. You may also be asked to undergo a stress test in order to find out the response of your heart to exercise. Exercise can increase your frequency of PVCs. You can also have blood tests to test your thyroid hormone, magnesium, potassium and other hormones to determine whether they're insufficient. This could cause PVCs.

Once your doctor has confirmed that you have PVCs and has ruled out any serious diseases, the decision on whether to treat them will be contingent on how much they're impacting your life and the frequency at which they occur. If they happen only on occasion and don't trigger any symptoms, it's unlikely that your doctor will prescribe any medication to decrease the frequency or severity of them.

If you experience frequent PVCs that trigger the sensation of palpitations or other symptoms, such as feeling lightheaded or like you're going to faint, your doctor may suggest medications for you, such as beta blockers or calcium channel blockers. Changing your lifestyle to avoid triggers, such as smoking, caffeine, and excessive stress, can also reduce the frequency of instances of these abnormal pulses.

The following is a list of preventatives.

PVCs can cause no symptoms or heart palpitations that can be described as "skipped beats" or flutters in the chest. Sometimes, these episodes cause an increase in pressure or fullness in the chest. Other times they can make a person feel faint. These episodes are caused by the heart not pumping as effectively as it should. Frequent PVCs increase a person's risk of developing dilated Cardiomyopathy, a condition wherein the heart expands and is unable to pump blood.

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

Some people find that changing their diet can help reduce PVCs. For instance, they can, avoid foods that contain preservatives that can disrupt the heart rhythm. These include disodium guanylate, diazole, and disodium inosinate sodium (E282-283). Eat more fruits and veggies to get sufficient magnesium.

Regular health checks are crucial as are annual physicals. These tests can help you identify any heart-related conditions that could cause your PVCs. It is also recommended to refrain from smoking and adhere to the healthy eating program. This could increase the frequency of episodes.

A survey of 14 normal hospital wards found that healthcare staff were generally aware of preventive measures for vascular catheter-associated infection, but their self-assessment of conformity to these guidelines was low. Compliance improved following an intervention to improve feedback, but was still low on a few of the observed wards. This suggests that education on how to implement preventive measures is required and that the areas that are not as well-adjusted should be targeted for infection surveillance. These data can be used to guide quality improvement initiatives in these wards. This will likely involve additional education and training for personnel. It will also be necessary to ensure that the correct materials for implementing the preventive measures are available.

Signs and symptoms

Premature ventricular contractions can cause your heartbeat to skip beats or flutter. These arrhythmias can be normal, or they could indicate that you have serious heart problems.

In healthy people, sporadic PVCs aren't a problem and they usually go away on their own. If you're suffering from a lot of them, they could cause dizziness or weakness. If you're worried you might be experiencing dizziness or weakness, talk to your doctor about them. They may need to determine the issue by taking an medical history and giving you an examination. They'll also probably want to conduct an electrocardiogram (ECG or EKG) or other tests.

A quick ECG test allows your doctor to see the pulse of your heart moving through your body over the course of a brief period. The test will reveal if you have PVCs. Your doctor may also suggest to perform a 24- or 48-hour Holter monitor, which records your heartbeat over longer periods of time. These tests can help differentiate PVCs from arrhythmias that cause heart palpitations. You can wear an event monitor, which is a portable device which records your heart rhythm for 30 days.

Other heart tests might be needed, depending on the cause of your PVCs. For example an cardiologist may test your blood pressure and do an ultrasound of your heart (echocardiogram). These tests can reveal if you have a condition that may be causing your PVCs or heart valves, 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 issue with electrolytes. For instance, a low level of potassium or high levels of calcium. This could be a sign of PVCs or other conditions that could cause them, such as anxiety disorders and anemia.

You may be referred to an electrophysiologist who is able to treat abnormal heart rhythms. If you suffer from structural heart disease the doctor may need to conduct additional tests, like an MRI or CT scan of your chest. These tests will tell you if you have damage to your heart, and how serious it is. In certain cases, a doctor might suggest an implantable pacemaker or ICD to treat the underlying issue creating your PVCs.
