Why It's Important to See a Doctor

Premature ventricular contractures (PVCs) are a form of irregular heartbeat. These extra beats usually aren't risky, and they may go away on their own.

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

Diagnosis

PVCs are caused by electrical impulses that reverberate through the SA node, a structure found in the lower chambers of the heart. This causes the next heartbeat to delay, which can cause a feeling like fluttering or skipped beats. PVCs may occur alone, or in repeated patterns. Two consecutive PVCs are known as doublets, whereas three or more consecutive PVCs are referred to as the term ventricular Tachycardia (VT).

Some people do not experience any symptoms, while others experience heart palpitations. This can feel like the sound of a beating heart or a rapid heartbeat. Other symptoms that are common are fatigue or dizziness, or a feeling of being sick.

Many people with occasional PVCs do not require treatment. If a person experiences frequent episodes, doctors may recommend a change in lifestyle or diet like limiting caffeine, alcohol and stress. They can also prescribe medications like beta-blockers and 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 check their general health. They can also perform an electrocardiogram (ECG) to take 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. In certain instances doctors may request blood tests to look for an electrolyte imbalance or toxic effects from drugs.

Sometimes, a pvc physician may refer a patient to a specialist for heart rhythm problems, or an electrophysiologist, for further evaluation. This windows doctor can confirm a diagnosis of PVCs and determine if they are malignant or benign.

PVCs are everywhere and aren't usually harmful unless they are used frequently or for a long period of time. This could lead to a weakening of the heart muscle, or a condition known as pvc-induced cardiomyopathy. This is most prevalent in older people or those with some form of heart disease. It can also occur in healthy people with an uninvolved heart, however it is more likely to occur in those who exercise regularly. Usually, this isn't an issue that is serious however it is crucial to consult an expert if you notice symptoms such as fainting or fatigue.

Treatment

For many people, occasional PVCs may not cause any symptoms or are harmless and need no 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 as soon as possible.

A cardiologist begins by interviewing you and doing physical examination, and monitoring your heart using a stethoscope for any irregular beats. Additionally, you will undergo an electrocardiogram, which records the electrical signals of your heart to detect any arrhythmias. If an arrhythmia is detected, a 24-hour Holter monitor or a portable ECG is required to detect the irregular rhythm for longer periods of time. These devices will help doctors determine whether you have PVCs and the reason for them which could be due to an imbalance in electrolytes, toxicity of drugs or other factors.

You may be asked to undergo an echocardiogram (an ultrasound of your heart) to determine the health of your heart is good and to look for structural issues that could lead to PVCs. You may also be asked to undergo an exercise test to assess how your heart reacts to exercise. Exercise can increase your frequency of pvcs. You may also undergo blood tests to assess your magnesium, potassium and thyroid hormone levels to find out whether they are low which could contribute to the development of PVCs.

If your double glazing doctor confirms that you suffer from PVCs, and has ruled any serious diseases out, the treatment you choose to take will depend on how they affect your life and how frequently they occur. If they happen only on occasion and don't cause any symptoms, it's unlikely that your glazing doctor will suggest any medication to decrease their frequency or severity.

If you experience frequent PVCs that cause heart palpitations, as well as other symptoms such as light-headedness or feeling like you're going to faint, your physician might recommend medications, such as beta blockers or calcium channel blockers. Altering your lifestyle to stay clear of triggers, such as smoking, caffeine and excess stress, can help lower the number of times you experience these abnormal pulses.

The following is a list of preventions.

PVCs can cause no symptoms or heart palpitations, that can be described as "skipped beats" or flutters in the chest. These episodes can cause feelings of pressure or fullness, or they may cause you to feel faint. These episodes result from the heart not pumping as efficiently as it should. PVCs are linked to an increased risk of developing dilated cardiac myopathy. This is a condition where the heart gets larger and is unable to pump blood.

PVCs are often caused by changes in body chemistry. This is due to the release of thyroid hormones and adrenaline as well as drinking alcohol or caffeine. Stress or excess weight, as well as a lack of exercise, can trigger these episodes.

Certain people find that changing their diet can help reduce the number of PVCs. For example, they can avoid foods which contain preservatives that could cause a disturbance in the heartbeat, for example disodium guanylate (E621), disodium inosinate (E627) and diazole sodium (E282-283). Eat more fruits and vegetables to get enough magnesium.

Regular health checks are essential as are annual physicals. These tests can help diagnose any heart-related conditions that could cause your PVCs. It is also recommended to adhere to an appropriate diet and avoid smoking, which could increase the frequency of your episodes.

A survey of healthcare workers on 14 wards of a normal hospital revealed that they were aware of the preventive measures for vascular catheter-associated infections, but that their self-assessed compliance with these practices was low. After a feedback program that improved compliance on certain wards, but it was still not as high. This suggests that training on the best ways to implement preventive measures is necessary and that wards that are not complying should be targeted for infection surveillance. This information could be used to guide the implementation of additional quality improvement initiatives on these wards. This will likely require additional education and training of personnel. It will also require making sure that the appropriate materials are in place for the implementation of the preventive measures.

Symptoms

Premature ventricular contractions can cause your heart to skip beats or be fluttering. These arrhythmias aren't necessarily dangerous or they can be a sign of serious heart problems.

In healthy people, occasional PVCs aren't a problem and they generally disappear by themselves. If you've got many of them, they can cause dizziness or weakening. If you're concerned you might be experiencing dizziness or weakness, talk to your upvc window doctor about the symptoms. They might need to diagnose the problem by taking an history of your medical condition and performing a physical exam. They may also want to conduct an electrocardiogram or other tests.

A short ECG test allows your doctor to see the signal of your heartbeat going through your body over a a short period of time. The test will show whether you have PVCs. Your doctor might also suggest a Holter monitor that records your heartbeat over a longer amount of time. These tests can help differentiate PVCs from arrhythmias that cause heart palpitations. You can also wear an event monitor, which is a portable device that tracks your heart's rhythm over 30 days.

Other tests for the heart may be required, depending on the reason behind your PVCs. For example, a cardiologist might check your blood pressure, and also perform an ultrasound of your heart (echocardiogram). These can help find whether you suffer from a condition that is the cause of your PVCs, such as cardiomyopathy, mitral valve prolapse or heart failure.

Your window & door doctor may also have to conduct a blood test to see what the problem is with your electrolytes, such as low potassium or high calcium levels. This could indicate that you have PVCs or a different problem such as anemia, or anxiety disorders.

You may be directed to an electrophysiologist, an expert who specializes in treating heart rhythms that are abnormal. If you suffer from structural heart disease, this specialist might need to do other tests, like an MRI or CT scan of your chest. These tests can determine if you have damage to your heart and how severe it is. In certain cases, a specialist may recommend an implanted pacemaker to treat the condition which is causing the PVCs.
