Why It's Important to See a Doctor
Premature ventricular contractures (PVCs) are a type of irregular heartbeats. These extra beats aren't usually dangerous, and they can disappear on their own.
To determine PVC, doctors will listen to your heartbeat, and also check other vital indicators. They might recommend an Holter monitor which tracks your heart's electrical impulses over the course of 24 hours. They can also request blood tests for checking your thyroid hormones and electrolyte levels.
Diagnosis
PVCs are caused by electrical impulses from the heart's lower chambers ventricles misfire through a structure known as the SA node. This causes the next heartbeat to be delayed, leading to the sensation of the heart is fluttering or skips beats. PVCs can occur in one pattern or in repeated patterns. Two consecutive PVCs are known as doublets. Three or more consecutive PVCs are referred to as the condition known as ventricular Tachycardia (VT).
Some people are not experiencing any symptoms, while others experience palpitations. It could be a pounding heartbeat or a skipping heartbeat. Other symptoms include fatigue, dizziness, or feeling unwell.
Many people who suffer from occasional PVCs do not require any treatment. If a person experiences frequent episodes, doctors might suggest a change to the way of life or diet like limiting caffeine, alcohol and stress. They may also prescribe medication such as beta-blockers or calcium channel blockers that can reduce the heart rate and lower blood pressure.
Doctors will ask the patient about their medical history and conduct an examination of the body to check on their general health. They may also use a Holter monitor to record the heart's rhythms for longer periods of time, or an electrocardiogram, which captures a picture of the electrical activity within the heart. In certain instances, doctors may order blood tests to determine if there is an electrolyte imbalance or toxic effects from drugs.
A pvc doctor may refer a patient to an electrophysiologist, or a specialist in heart rhythm disorders for further examination. This specialist can confirm the diagnosis of PVCs and determine whether they are benign or not.
PVCs can be found everywhere and are generally not harmful unless they are used frequently or for a long period of time. This can cause weakening of the heart muscle, or a condition known as pvc-induced cardiomyopathy. This is most common in older people, or those who have any 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. This is not a serious issue, but you should tell your doctor if symptoms like fatigue or fainting occur.
Treatment
PVCs are not harmful or cause any symptoms in the majority of people. door and window doctor do not require treatment. But when you do feel your heart is lagging a beat or is racing, it's important to see a doctor as soon as you can.
A cardiologist will begin by interviewing you and performing a an examination of your body, listening to your heart with the stethoscope to look for irregular beats. You will also have an electrocardiogram (ECG) done to record the electrical impulses in your heart and reveal any arrhythmias. If an arrhythmia is identified it is recommended to use the use of a portable ECG or a 24-hour Holter monitor will be required to record the abnormal rhythm for longer durations of time. These devices will help doctors determine if you suffer from PVCs and their causes like an imbalance in electrolytes, toxic drugs or other causes.
You may be required to undergo an echocardiogram (an ultrasound of your heart) to determine whether your heart health is good and to look for structural issues that could lead to PVCs. You might also be asked to take stress tests to assess the response of your heart to exercise. Physical activity can increase your frequency of pvcs. You may also undergo blood tests to determine your thyroid, magnesium, and potassium hormone levels to find out if they are too low and can cause the formation of PVCs.
If your doctor confirms that you suffer from PVCs and has ruled any serious diseases out, the treatment option you choose will depend on how they affect your life and how often they occur. If they happen only on occasion and don't trigger any symptoms, it's unlikely your doctor will recommend any medication to reduce their frequency or severity.
If you experience frequent PVCs that can trigger heart palpitations, or other symptoms such as feeling light-headed or fainting, your doctor might prescribe medications like beta blockers and calcium channel blockers. Changes in your lifestyle, such as cutting down on smoking, caffeine and stress levels that are excessive can also decrease the frequency of these abnormal pulses.
Prevention
PVCs can cause no symptoms or heart palpitations, that can feel like "skipped beats" or flutterings in the chest. Sometimes, these episodes trigger a fullness or pressure in the chest, and other times they can make a person feel faint. These episodes result from the heart not pumping as effectively as it should. Frequent PVCs increase a person's risk 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 thyroid hormones and adrenaline and alcohol consumption or caffeine. Inactivity can also trigger these episodes and stress, as well as excessive weight.
Some people find that changing their diet can reduce the number of PVCs. For example, they can avoid foods which contain preservatives that could cause a disturbance to the heart rhythm, such as disodium Guanylate (E621), disodium inosinate (E627) diazole sodium (E282-283). They can also eat more vegetables and fruits to ensure they are getting sufficient magnesium and potassium.
Regular health checks are crucial and include annual physicals. These tests can help identify any heart issues that could be causing your PVCs. You should also follow an eat-healthy diet and avoid smoking, which could increase the frequency of your episodes.
A survey of 14 normal hospital wards revealed that healthcare personnel were generally aware of preventive measures for vascular catheter-associated infection, but their self-assessment of compliance to these practices was low. Compliance improved following feedback interventions, but was still low on some of the observed wards. This suggests that education is needed on how to implement preventive measures and those wards that are not than compliant should be targeted for infection monitoring. These data can be used to guide quality improvement initiatives in these wards. This will likely require additional education and training of staff. It will also require making sure that the appropriate materials are in place for the implementation of the preventive measures.
Symptoms
Involuntary ventricular contractions that are premature can cause your heartbeat to skip beats or flutter. These arrhythmias may be harmless, but they could indicate that you are suffering from serious heart issues.
In healthy people, occasional PVCs aren't an issue and they generally disappear on their own. If you've got a lot of them, it can cause dizziness or weakness. Speak to your doctor if you are concerned. You may need to give your medical history and they might also perform an examination of the body to determine the cause. They'll likely also need to do an electrocardiogram (ECG or EKG) or other tests.
A short ECG test allows your doctor to see the heartbeat signal going through your body over a the course of a brief period. If you have PVCs, they'll be visible in the test. Your doctor may also suggest to do an overnight or 24-hour Holter monitor that records your heartbeat for longer durations of time. These tests can help distinguish PVCs from arrhythmias that cause heart palpitations. You may also carry a device that can record your heart's rhythm over a period of 30 days, referred to as an event monitor.
Other heart tests may be required, based on the reason behind your PVCs. For example an cardiologist may test your blood pressure and do an ultrasound of the heart (echocardiogram). These tests can tell if you suffer from an illness like heart failure, mitral valve prolapse, or cardiomyopathy.
Your doctor may also be required to perform an analysis of your blood to determine the issue with electrolytes. For example, low potassium or high levels of calcium. This could be an indication of PVCs or other conditions that can cause them, like anemia and anxiety disorders.
You could be referred to an electrophysiologist who can treat irregular heart rhythms. This specialist may need to conduct additional tests if you are suffering from structural heart diseases like an CT or MRI scan of your chest. These tests will tell you whether you've damaged your heart and how serious it is. In some instances, the doctor might recommend the use of a pacemaker or ICD to treat the underlying issue causing your PVCs.
