Why It's Important to See a Doctor
Premature ventricular contractions (PVCs) are a kind of irregular heartbeat. These extra beats are usually not dangerous and can go away by themselves.
To determine PVC Doctors will listen to your heartbeat and look for other vital signs. They might recommend an Holter monitor, a device that tracks your heart's electrical impulses over a period of 24 to 48 hours. They can also request blood tests to check your electrolyte levels and thyroid hormones.
Diagnosis
PVCs occur when electrical impulses coming 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 be delayed, leading to an experience similar to racing or skipped beats. PVCs can be seen in a single pattern or in repeated patterns. Doublets are PVCs that occur in a series of. Ventricular tachycardia refers to three or more consecutive ones.
Some people have no symptoms, but others experience palpitations. It can be felt as an unsteady heartbeat or a skipping heartbeat. Other symptoms include dizziness, fatigue, or feeling unwell.
Many people who have occasional PVCs don't need any treatment. If a patient experiences frequent episodes, a doctor may recommend a change to diet or lifestyle. For instance the restriction of caffeine, stress, and alcohol. They can also prescribe medications like calcium channel blockers or beta-blockers that can reduce the heart rate and lower blood pressure.
Doctors will ask the patient about their medical history and perform a physical examination to determine their general health. They can also perform an electrocardiogram (ECG) to capture a snapshot of the heart's electrical activity or a Holter monitor that is worn for longer periods and monitors the heart's rhythms over time. In some cases, doctors may order blood tests to determine if there is an electrolyte imbalance or drug toxicity.
A pvc doctor might refer the patient to an electrophysiologist or a specialist in heart rhythm disorders for further examination. This specialist can confirm the diagnosis of PVCs and determine if they are benign or not.
PVCs are all over the place and aren't usually harmful unless they are used frequently or for a long time. This can cause weakening of the heart muscle or a condition referred to as pvc-induced cardiomyopathy. This is more prevalent in older adults or those with heart disease. It can also occur in healthy people with an uninvolved heart, however this is more likely in those who exercise regularly. Usually, this isn't an issue to worry about but it's important to tell your doctor if you experience symptoms such as fainting or fatigue.
Treatment
For many people, sporadic PVCs aren't likely to cause symptoms or are harmless and require no treatment. But those who do experience a sensation like your heart is lagging an beat or is racing, it's crucial to speak to a doctor as soon as you can.
A cardiologist will interview you and then perform physical examinations, listening to your heart through an stethoscope to identify any irregular heartbeats. Additionally, you will have an electrocardiogram (ECG) done that records the electrical signals in your heart and detect any arrhythmias. If an arrhythmia has been detected then the use of a portable ECG or a 24-hour Holter monitor is required to record the abnormal rhythm for longer durations of time. These devices can help doctors determine if you have PVCs and the reason behind them, like 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 problems which could lead to PVCs. You could also have a stress test to see how your heart reacts to physical exercise can increase the frequency of your pvcs. You may also be able to have blood tests to assess your magnesium, potassium and thyroid hormone levels to determine whether they are low, which can contribute to the formation of PVCs.
After your doctor confirms that you have PVCs, and has ruled any serious illnesses out, the treatment option you choose depends on how they impact your life and how frequently they occur. If they happen only infrequently and do not cause any symptoms then your doctor is unlikely to recommend any treatment that can decrease their frequency or severity.
If you experience frequent PVCs that trigger palpitations and other symptoms, such as feeling lightheaded or like you're going to faint, your physician might suggest medication for you, such as beta blockers or calcium channel blockers. Changes in your lifestyle, like avoiding caffeine, smoking and stress levels that are excessive can reduce the frequency of these abnormal pulses.
The following is a list of preventatives.
There are people who do not experience symptoms whatsoever from PVCs, or feel heart palpitations (irregular heartbeats) which can appear as "skipped" beats or a fluttering sensation in the chest. These episodes can cause feelings of pressure or fullness or they may cause you to feel faint. These episodes are caused by the heart not pumping as well as it should. PVCs are linked to an increased risk of developing dilated cardiac myopathy. This is a condition where the heart expands and becomes in a position to not pump blood.
PVCs are usually caused by changes in body chemistry. This is due to the release of thyroid hormones and adrenaline, as well drinking alcohol or caffeine. Inactivity can also trigger these episodes, as can stress or excessive weight.
Certain people find that changing their diet can help reduce the amount of PVCs. For instance, they can avoid foods with preservatives, which can cause disturbances in the heartbeat, for example disodium guanylate (E621), disodium inosinate (E627) and diazole sodium (E282-283). You can also consume more fruits and vegetables to ensure they're getting sufficient magnesium and potassium.
It is essential to have regular health checks, including yearly physicals and lab tests. window doctors can help identify any underlying heart conditions which could be causing your PVCs. Also, you should not smoke and adhere to a healthy diet plan. This could increase the frequency of episodes.
A survey of healthcare professionals on 14 normal hospital wards found that they were mostly aware of the preventive measures for infections caused by vascular catheters however, their self-assessment of compliance with these guidelines was low. After a feedback intervention the compliance level improved on a few wards, but it was still not as high. This suggests that training is required on how to implement preventive measures and those wards that are not compliant need to be targeted for monitoring of infection. These data can be used to guide quality improvement initiatives in these wards. This will likely involve further training and education for personnel. It is also necessary to ensure that the appropriate tools for implementing the preventive measures are available.
Signs and symptoms
The premature contraction of the ventricular muscle can cause your heartbeat to skip beats or flutter. These arrhythmias could be harmless, or they could indicate you are suffering from serious heart issues.
In healthy people, PVCs that occur occasionally are not an issue. They usually disappear by themselves. If you've got a lot of them, they can cause dizziness or weakness. If you're concerned, talk to your doctor about them. You might be required to provide your medical history and they might also perform a physical examination in order to identify the issue. They may also do an electrocardiogram (ECG or EKG) or other tests.
A quick ECG test allows your doctor to see the heartbeat signal moving through your body for a a short period of time. The test will determine whether you have PVCs. Your doctor may also recommend the use of a Holter monitor that tracks your heartbeat over a longer period of time. This can help distinguish PVCs from other types of arrhythmias that cause heart palpitations. You can also wear an event monitor, a handheld device that keeps track of your heart's rhythm for 30 days.
Other heart tests might be required, depending on the cause of your PVCs. A cardiologist may check your blood pressure, or perform an echocardiogram (ultrasound of the heart). These tests can reveal the presence of a medical condition that is causing your PVCs like mitral valve prolapse or heart failure.
Your doctor may also need to perform a blood test to determine the problem with your electrolytes. For instance, a low level of potassium levels or high levels of calcium. This could be an indication of PVCs or other conditions that may cause them, including anemia and anxiety disorders.
You could be referred to an electrophysiologist who is able to treat abnormal heart rhythms. This specialist may need to conduct additional tests if you have heart problems that are structural, such as a CT or MRI scan of your chest. These tests can tell if you have damage to your heart, and how serious it is. In certain cases, a specialist may recommend a pacemaker to treat the issue which is causing the PVCs.
