Why It's Important to See a Doctor
Premature ventricular contractions (PVCs), are a form of irregular heartbeat. These extra beats are usually not risky, and they may disappear by themselves.
To determine PVC Doctors will listen to your heartbeat and check other vital indicators. They might recommend a Holter monitor which tracks your heart's electrical impulses over a period of 24 to 48 hours. They might also order blood tests to check the levels of electrolytes and thyroid hormones.
Diagnosis
PVCs are caused by electrical impulses which misfire through the SA node, a structure located in the lower chambers of the heart. This delays the next heartbeat which can cause the feeling of fluttering or skipped beats in the chest. PVCs may occur alone or in repeated patterns. Doublets are PVCs that occur in a series of. Ventricular tachycardia refers to three or more consecutive PVCs.
Some people are not experiencing any symptoms, while others experience palpitations. This can feel like a pounding heartbeat or a skipping heartbeat. Other symptoms include dizziness, fatigue, or a feeling that you're unwell.
Many people who suffer from occasional PVCs do not require any treatment. If a person has frequent episodes, doctors might suggest a change in diet or lifestyle like limiting alcohol, caffeine and stress. They may prescribe medication such as beta-blockers or calcium channel blockers to lower blood pressure and slow down the heart rate.
Doctors will ask the patient about their medical history and perform a physical examination to check on their general health. They may also use an electrocardiogram (ECG) to take a snapshot of the heart's electrical activity or a Holter monitor that is worn for longer time periods and monitors the heart's rhythms over time. Doctors may request blood tests in some instances to look for imbalances in electrolytes or drug toxicity.
A pvc physician may refer the patient to an electrophysiologist or specialist in heart rhythm disorders for further evaluation. This doctor can confirm the diagnosis of PVCs and determine if they are malignant or benign.
PVCs can be found everywhere and aren't usually harmful when used frequently or for a long time. This can cause weakening of the heart muscle, or a condition referred to as pvc-induced cardiomyopathy. It is more common in people who are older, or those who have any form of heart disease. This can happen to healthy people with normal, normal hearts. However, it's more prevalent in people who exercise regularly. Most of the time, this isn't an issue to worry about however it is crucial to consult a doctor if you notice symptoms such as fainting or fatigue.
Treatment
PVCs are not harmful or cause symptoms in many people. They do not require treatment. But, for those who do experience a sensation like your heart is lagging a beat or is racing, it's vital to see a doctor as soon as you can.
A cardiologist will start by conducting an interview and then perform a physical examination, and listening to your heart with a stethoscope for any irregular beats. You will also undergo an electrocardiogram that captures the electrical impulses of your heart, allowing you to identify any arrhythmias. If an arrhythmia is identified it is recommended to use 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 the underlying cause for them, such as an electrolyte imbalance or drug toxicities, or other causes.
An echocardiogram, also known as an ultrasound of your heart, may be ordered to assess if your heart is healthy and look for any signs of structural problems that could lead to PVCs. You might also be required to undergo stress tests to find out the response of your heart to exercise. Physical activity can increase your frequency of PVCs. You can also take blood tests to determine your thyroid hormone, magnesium, potassium and other hormones to see whether they're insufficient. This could lead to PVCs.
If your doctor has confirmed that you suffer from PVCs, and has ruled any serious diseases 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 symptoms then your doctor is unlikely to recommend any treatment to reduce 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 may suggest medications like beta blockers or calcium channel blockers. Altering your lifestyle to stay clear of triggers, such as smoking, caffeine and excess stress, can also aid in reducing the frequency of times you experience these irregular pulses.
Prevention
A person might not experience any symptoms at all from PVCs, or feel heart palpitations (irregular heartbeats) which can feel like "skipped" beats or a fluttering sensation in the chest. These episodes can create an feeling of fullness or pressure, or make you feel faint. These episodes are caused by the heart not pumping as efficiently 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 is unable to pump blood.
PVCs often are caused by changes in the body's chemistry. This includes the release of adrenaline and thyroid hormones, and drinking alcohol or caffeine. Stress or weight gain or a lack of exercise, can trigger these episodes.
Certain people find that a change in their diet can reduce their PVCs. They can, for example, avoid foods that contain preservatives that could cause disturbances to the heart rhythm. These include disodium Guanylate, diazole, and disodium Inosinate Sodium (E282-283). You can also take in more fruits and vegetables to ensure that they get enough magnesium and potassium.
It is crucial to undergo regular health check-ups, which include annual physicals and lab tests. These tests can help diagnose any heart conditions that may cause your PVCs. It is also recommended to adhere to a healthy eating plan and refrain from smoking, which can increase the frequency of your episodes.
A survey of 14 regular hospital wards found that healthcare personnel were generally aware of preventive measures for vascular catheter-associated infection, but their self-assessment of compliance to these procedures was not high. Compliance improved following a feedback intervention however, it was still lower on some of the wards that were surveyed. 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 inform quality improvement initiatives in these wards. This will likely require further education and training for personnel. glass doctor will also require making sure that the right materials are available for the implementing of the preventive measures.
Symptoms
If you feel your heart is skipping beats or fluttering, it may be due to premature ventricular contractions. These arrhythmias may be harmless or they could be the sign of heart issues.
In healthy individuals, PVCs that occur occasionally are not an issue. They typically disappear by themselves. But if you have many of them, they could cause dizziness or weakness. If you're concerned, talk to your doctor about the symptoms. You might need to provide a medical history, and they might also perform an examination to determine the cause. They may also conduct an electrocardiogram (ECG or EKG) or other tests.
A short ECG test lets your doctor see the heartbeat signal going through your body over a an extremely short time. The test will determine if you have PVCs. Your doctor might also want to do an overnight or 24-hour Holter monitor which monitors your heartbeat for longer durations of time. These can help differentiate PVCs from other arrhythmias that cause heart palpitations. You might also wear a portable device that can record your heart rate over 30 days, called an event monitor.
Other tests for your heart might be required, based on the reason for your PVCs. A cardiologist may check your blood pressure or perform an echocardiogram (ultrasound of the heart). These tests can reveal whether you suffer from a condition that may be the cause of your PVCs or heart valves, such as cardiomyopathy, mitral valve prolapse or heart failure.
Your doctor may also be required to conduct a blood test to determine the issue with electrolytes. For instance, you may have low potassium levels or a high level of calcium. This could be a sign that you suffer from PVCs or another problem such as anemia, or anxiety disorders.
You could be referred to an electrophysiologist who can treat irregular heart rhythms. If you suffer from structural heart disease the specialist may have to do other tests, such as an MRI or CT scan of your chest. These tests will determine whether your heart is damaged and how severe it is. In some cases, a specialist may recommend pacemakers to treat the issue that is causing the PVCs.
