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 disappear by themselves.
To determine PVC doctors listen to your heartbeat, and also check other vital signs. They might order an Holter Monitor that records the electrical impulses generated by your heart over a period of between 24 and 48 hours. They might also order blood tests to determine the levels of electrolytes and thyroid hormones.
Diagnosis
PVCs occur when electrical impulses coming from the lower chambers of the heart ventricles, or lower chambers, fail to pass through a structure referred to as the SA node. This delays the next heartbeat and causes the feeling of fluttering or skipped beats in the chest. double glazing doctor can occur in one pattern or repeated patterns. Two consecutive PVCs are known as doublets, while three or more consecutive PVCs constitute the term ventricular Tachycardia (VT).
Some people are not experiencing any symptoms, whereas others experience heart palpitations. This can feel like a pounding heartbeat or a slurred heartbeat. Other symptoms that are common are fatigue, dizziness or a sensation of being unwell.
Many people who experience occasional PVCs do not require any treatment. If someone is experiencing frequent episodes, doctors could recommend a change in lifestyle or diet including a reduction in caffeine, alcohol and stress. They may prescribe medications such as beta-blockers and calcium channel blockers to lower blood pressure and slow the heart rate.
Doctors will inquire about the medical history of the patient and conduct a physical exam to check their general health. They may also utilize 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 of the heart. Doctors may request blood tests in some instances to determine if there are electrolyte imbalances or drug toxicity.
A pvc physician may refer a patient to an electrophysiologist, or a specialist in heart rhythm disorders for further evaluation. This doctor can confirm the diagnosis of PVCs and determine if they are benign or not.
PVCs are fairly common and rarely cause any issues, unless they happen frequently over a long time. This could lead to a weakening in the heart muscle or a condition known as pvc-induced cardiomyopathy. It is more common for people over the age of 65 or those with some type of heart disease. This can happen to healthy people who have a normal, normal heart. However, it is more prevalent in people who exercise regularly. It is not a major issue, but you should consult your physician if you notice symptoms such as fainting or fatigue occur.
Treatment
PVCs are not harmful or cause symptoms in a lot of people. They do not require treatment. If you feel that your heart is racing or slurring a beat, it's best to see a doctor right away.
A cardiologist will start by interviewing you and performing a an examination of your body, listening to your heart with an stethoscope to detect any irregular heartbeats. You will also have an electrocardiogram (ECG) performed to record the electrical impulses in your heart and detect any arrhythmias. If an arrhythmia is found it is recommended to have you will require a 24-hour Holter monitor or a portable ECG is required to record the irregular rhythm for longer durations of time. These devices will assist doctors determine whether you have PVCs and the reason behind them, such as an electrolyte imbalance, a drug toxicities, or other causes.
You might be required to undergo an echocardiogram (an ultrasound of your heart) to determine the health of your heart is in good order and to look for structural issues that could lead to PVCs. You could also have a stress test to check how your heart responds to exercise, since physical exercise can increase the frequency of your PVCs. You may also undergo blood tests to assess your thyroid, potassium, and magnesium hormone levels to find out whether they are insufficient, which can contribute to the formation of PVCs.
After your doctor confirms that you have PVCs and has ruled any serious illness out, the decision to treat them depends on how they impact your life and the frequency they occur. If they only occur occasionally and do not cause any symptoms then your doctor is unlikely to prescribe any medication to reduce their frequency or severity.
If you have 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. Lifestyle changes such as abstaining from smoking, caffeine and stress, can also decrease the frequency of these abnormal pulses.
Prevention
PVCs can cause no symptoms or heart palpitations which may be described as "skipped beats" or flutters in the chest. These episodes can create an feeling of fullness or pressure, or they may cause you to feel faint. These episodes result from the heart not pumping as effectively as it should. PVCs are associated with a higher chance of developing dilated cardiomyopathy. This is a condition in which the heart becomes enlarged and unable to pump blood.
PVCs are often caused by changes in body chemical chemistry. This is due to the release of adrenaline and thyroid hormones and alcohol consumption or caffeine. A lack of exercise can trigger these symptoms, as can stress or excess weight.
Some people find that changing their diet can help reduce PVCs. For example, they can avoid foods that contain preservatives that can cause a disturbance in the heart rhythm, such as disodium guanylate (E621), disodium inosinate (E627), and diazole sodium (E282-283). It is also recommended to consume more fruits and vegetables to ensure that they get sufficient magnesium and potassium.
Regular health checks are important, including yearly physicals. These tests can help identify any heart conditions that may be causing your PVCs. It is also recommended to avoid smoking and follow an appropriate diet plan. This can increase the frequency of episodes.
A survey of healthcare workers on 14 normal hospital wards found that they were mostly aware of the preventive measures that could be used to treat vascular catheter-associated infections However, their self-assessed compliance with these measures was poor. Compliance improved following an intervention to improve feedback, but was still low on some of the observed wards. This suggests that education on how to implement preventive measures is essential and that the wards that are not complying should be targeted for surveillance of infection. These data can be used to guide quality improvement initiatives in these wards. It is likely that this will require further education and training for personnel. It will also require making sure that the appropriate materials are available for the implementation of preventive measures.
Signs and symptoms
Premature ventricular contractions can cause your heartbeat to skip beats or be fluttering. These arrhythmias can be harmless or they could be the sign of heart issues.
In healthy individuals, occasional PVCs aren't a problem, and they generally disappear by themselves. If you've got a lot of them, it can cause dizziness or weakening. Talk to your doctor if you're worried. You might be required to provide a medical history, and they might also perform an examination to identify the issue. They'll also probably want to do an electrocardiogram (ECG or EKG) or other tests.
A quick ECG test allows your doctor to see the pulse of your heart going through your body over a the course of a brief period. If you have PVCs, they'll show up in the test. Your doctor might also want to do a 24- or 48-hour Holter monitor that 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, a portable device which records your heart rhythm for 30 days.
Other heart tests may be required, based on the reason behind your PVCs. For example, a cardiologist might check your blood pressure and do an ultrasound of your heart (echocardiogram). These tests can reveal if you have a issue that could 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 what's wrong with your electrolytes for example, low potassium levels or high calcium levels. This can be an indication of PVCs or other conditions that could cause them, such as anxiety disorders and anemia.
You may be referred to an electrophysiologist who can treat irregular heart rhythms. If you suffer from heart disease that is structural the specialist may have to do other tests, like an MRI or CT scan of your chest. These tests can tell if you have damage to your heart, and how serious it is. In some cases, a specialist may recommend pacemakers to treat the condition that causes the PVCs.
