Why It's Important to See a Doctor
Premature ventricular contractions (PVCs) are a kind of irregular heartbeat. These extra beats usually aren't risky, and they may disappear by themselves.
Doctors will monitor your heartbeat and look for other vitals indicators. They may order a Holter monitor, a device that records your heart's electrical impulses over a period of 24 to 48 hours. They might also order blood tests to determine your thyroid and electrolyte levels. hormones.
Diagnosis
PVCs occur when electrical impulses coming from the heart's lower chambers ventricles, or lower chambers, fail to pass through a structure called the SA node. This causes the next heartbeat to be delayed, causing the sensation of fluttering or skipped beats. PVCs can occur in one pattern or repeated patterns. Two consecutive PVCs are referred to as doublets, whereas three or more consecutive PVCs are referred to as the condition known as ventricular Tachycardia (VT).
Some people do not experience any symptoms, but others experience heart palpitations. This can feel like an unsteady heartbeat or a slurred heartbeat. Other symptoms that are common are fatigue or dizziness, or a feeling of being unwell.
Many people who suffer from occasional PVCs don't need any treatment. If a patient is experiencing frequent episodes, a physician may recommend a change to the diet or lifestyle. For instance, limiting caffeine, stress, and alcohol. 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 medical history of the patient and perform a physical examination to assess their general health. They may also utilize a Holter monitor to record the heart's rhythms for longer durations, or an electrocardiogram, which takes a snapshot at the electrical activity within the heart. Doctors may order blood tests in some cases to check for electrolyte imbalances or toxic effects of drugs.
A pvc doctor may refer patients to an electrophysiologist or a specialist in heart rhythm disorders for further examination. The doctor can confirm a diagnosis of PVCs and determine if they are malignant or benign.
PVCs are fairly common and don't usually ca us e any problems unless they happen frequently over a long time. This can cause a weakening in the heart muscle or a condition known as pvc-induced cardiomyopathy. This is more common in older people or people suffering from heart disease. It can also occur in healthy people with a normal heart, although it is more likely to occur in those who exercise regularly. It's not an issue that is serious but it's important to consult a doctor if you notice symptoms such as fainting or fatigue.
Treatment
PVCs aren't harmful or cause symptoms in a lot of people. They do not require treatment. But, for those who do experience a sensation like their heart has skipped an beat or is racing, it's crucial to see a doctor immediately.
A cardiologist will first interview you and conduct an examination of your body, listening to your heart through a stethoscope to detect any irregular beats. Additionally, you will have an electrocardiogram (ECG) done, which will record the electrical impulses that occur in your heart and reveal any arrhythmias. If an arrhythmia has been detected, an portable ECG or 24-hour Holter monitor is required to capture the irregular rhythm for longer periods of time. These devices will help doctors determine if you have PVCs, and their cause like an imbalance in electrolytes, drug toxicity or other causes.
You might be required to undergo an echocardiogram (an ultrasound of your heart) to determine whether your heart health is in good shape and to check for structural issues that could lead to PVCs. You might also be asked to take a stress test in order to determine the response of your heart to exercise. Physical activity can increase your frequency of PVCs. You can also have blood tests to test your thyroid hormone and magnesium, potassium, and other hormones to see whether they're low. This could lead to PVCs.
Once your doctor has confirmed that you're suffering from PVCs and has ruled out any serious illness, the decision on how to treat them will depend on how much they're impacting your life and how frequently they occur. If they happen only on occasion and don't cause any symptoms, it's unlikely that your doctor will suggest any medication to lessen their frequency or severity.
If you experience frequent PVCs that trigger palpitations and other symptoms, like lightheadedness or feeling like you're about to faint, your physician might suggest medication like beta blockers or calcium channel blockers. Lifestyle changes such as abstaining from smoking, caffeine, and excessive stress can reduce the frequency of these irregular pulses.
The following is a list of preventions.
There are people who do not experience symptoms at all from PVCs or heart palpitations (irregular heartbeats) which can feel like "skipped" beats or fluttering in the chest. These episodes can cause an feeling of pressure or fullness or they can make you feel faint. These episodes happen because the heart is not pumping as efficiently as it normally does. Frequent PVCs increase the chance of developing dilated cardiomyopathy, a condition wherein the heart gets larger and is unable to pump blood.
PVCs often are caused by changes in body chemical chemistry. This is due to the release of adrenaline and thyroid hormones as well as drinking alcohol or caffeine. Stress or excess weight and the absence of exercise can trigger these episodes.
Certain people find that altering their diet may help to reduce the number of PVCs. For instance, they could avoid foods which contain preservatives that could cause a disturbance to the heart rhythm, such as disodium Guanylate (E621), disodium inosinate (E627), and diazole sodium (E282-283). Eat more fruits and veggies to ensure that you get sufficient magnesium.
Regular health checks are essential as are annual physicals. They can aid in identifying any heart issues that could be causing your PVCs. You should also not smoke and adhere to an appropriate diet plan. This can increase the frequency of episodes.
A survey of healthcare professionals on 14 wards of a normal hospital found that they were mostly aware of the preventive measures for vascular catheter-associated infections, but that their self-assessed compliance with these measures was low. Compliance improved after a feedback intervention however it was still very low on a few of the wards surveyed. This suggests that education on the best ways to implement preventive measures is necessary and that wards that are not complying should be targeted for infection surveillance. These data can be used to inform quality improvement initiatives in these wards. This will likely involve more education and training for personnel. It is also necessary to ensure that the right materials for implementing the preventive measures are readily available.
Signs and symptoms
If you feel that your heart is skipping beats or fluttering, it may be due to premature ventricular contractions. These arrhythmias could be harmless, but they could be a sign that you have heart issues that are serious.
In healthy people, sporadic PVCs aren't a problem, and they usually disappear on their own. If you're suffering from a lot of them, they may cause weakness or dizziness. If you're worried about them, consult your doctor about the symptoms. You might need to provide a medical history, and they might also perform an examination to diagnose the problem. They might also need to conduct an electrocardiogram or other tests.
A short ECG test will allow your doctor to observe the pulse of your heart going through your body over a the course of a brief period. The test will reveal whether you have PVCs. Your doctor might also want to conduct an overnight or 24-hour Holter monitor which monitors your heartbeat for longer periods of time. These tests can help distinguish PVCs from arrhythmias causing heart palpitations. You can also wear an event monitor, which is a portable device which tracks your heart's rhythm over 30 days.
Other tests for the heart may be required, based on the cause of your PVCs. For instance a cardiologist could check your blood pressure and do an ultrasound of your heart (echocardiogram). These tests can determine if you suffer from a condition like heart failure, mitral valve prolapse, or cardiomyopathy.
Your doctor might also need to run a blood test to see what is wrong in your electrolytes, such as low potassium or high calcium levels. This could be a sign that you suffer from PVCs or another condition such as anemia or anxiety disorders.
You might be directed to an electrophysiologist, one of the specialists who specialize in treating abnormal heart rhythms. This specialist may need to conduct additional tests if you suffer from heart problems that are structural, such as an CT or MRI scan of your chest. These tests will determine whether your heart is damaged and how severe the damage is. In some instances, the doctor might suggest an implantable pacemaker or ICD to treat the condition that is the cause of your PVCs.
