Why It's Important to See a Doctor
Premature ventricular contractions (PVCs) are a form of irregular heartbeat. These extra beats usually aren't hazardous, and they could go away on their own.
To determine PVC doctors listen to your heartbeat, and also check other vital indicators. They may order an Holter Monitor that captures the electrical impulses of your heart over a time of between 24 and 48 hours. They may also order blood tests for checking your thyroid hormones and electrolyte levels.
Diagnosis
PVCs are caused by electrical impulses that reverberate through the SA node, which is a structure in the lower chambers of the heart. This causes the next heartbeat to be delayed, leading to an experience similar to the heart is fluttering or skips beats. PVCs may occur alone or in repeated patterns. Two consecutive PVCs are referred to as doublets, whereas three or more consecutive PVCs constitute the condition known as ventricular Tachycardia (VT).
Some people have no symptoms, while others experience palpitations. It can be felt as a pounding heartbeat or a rapid heartbeat. Other symptoms include dizziness, fatigue, or feeling unwell.
Many people who have occasional PVCs don't need any treatment. If someone is experiencing frequent episodes, doctors could recommend a change in the way of life or diet, such as limiting caffeine, alcohol and stress. They may also prescribe medications, such as beta-blockers and calcium channel blockers, which can slow the heart rate and lower blood pressure.
Doctors will inquire about their medical history and perform an examination of the body to assess their general health. They can also perform an electrocardiogram (ECG) to get a snapshot of the heart's electrical activity, or a Holter monitor, which is worn for longer periods and captures the heart's rhythms over time. In certain cases, doctors may order blood tests to check for an electrolyte imbalance or drug toxicity.
Sometimes, the window doctor repairmywindowsanddoors.co.uk will refer a patient to a specialist in heart rhythm problems, or an electrophysiologist, for further evaluation. This doctor will confirm a diagnosis of PVCs, and determine whether they are benign or malignant.
PVCs are quite common and rarely cause any issues, except when they are frequent over a long time. This can lead to a weakened in the heart muscle, or a condition known as pvc-induced cardiac myopathy. This is more common in older adults or those suffering from heart disease. It can also occur to healthy individuals with a normal, normal heart. However, it's more prevalent in people who exercise regularly. Most of the time, this isn't an issue that is serious, but it is important to speak with an expert if you notice symptoms such as fainting or fatigue.
Treatment
For many people, sporadic PVCs aren't likely to cause symptoms or require no treatment. If you feel like your heart is racing or skipping an entire beat, you need to consult a doctor immediately.
A cardiologist will then interview you and conduct an examination of your body and listen to your heart using an stethoscope to identify any irregular beats. You'll also undergo an electrocardiogram that records the electrical signals of your heart, allowing you to identify any arrhythmias. If an arrhythmia has been identified, a portable ECG or 24-hour Holter monitor will be required to capture the irregular rhythm for longer periods of time. These devices will assist doctors determine whether you have PVCs and the cause of them, like an electrolyte imbalance, drug toxicities, or other causes.
An echocardiogram, an ultrasound of your heart, could be ordered to assess whether your heart is in good health and to look for indications of structural issues that could lead to PVCs. You could also have a stress test to see how your heart reacts to exercise, as physical exercise can increase the frequency of your PVCs. You may also be able to have blood tests to determine your thyroid, potassium, and magnesium hormone levels to determine whether they are insufficient which could contribute to the development of PVCs.
After your doctor has confirmed that you suffer from PVCs and has eliminated any serious illnesses and has made a decision about whether or not 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 decrease the frequency or severity of them.
However, if you have frequent PVCs that cause the sensation of palpitations or other symptoms, like lightheadedness or feeling like you're going to faint, your physician may suggest medications, such as beta blockers or calcium channel blockers. Altering your lifestyle to avoid triggers, like smoking, caffeine, and excessive stress, can reduce the frequency of times you experience these abnormal pulses.
Prevention
PVCs can cause no symptoms or heart palpitations which may be described as "skipped beats" or flutterings in the chest. Sometimes, these episodes cause the chest to feel full or swollen in the chest, and at other times they can make someone feel faint. These episodes are caused by the heart is not functioning as efficiently as it should. The frequent PVCs increase the chance of developing dilated Cardiomyopathy, a condition in which the heart gets larger and is unable to pump blood.
PVCs are usually caused by changes in body chemical balance. These include the release of adrenaline and thyroid hormones, as well as drinking alcohol or caffeine. A lack of exercise can also trigger these episodes like stress or excess weight.
Some people can find that a change in diet can reduce their PVCs. For example, they can avoid foods that contain preservatives that can cause a disturbance in the heartbeat, for example disodium Guanylate (E621) disodium inosinate (E627), and diazole sodium (E282-283). It is also recommended to take in more fruits and vegetables to ensure that they get enough magnesium and potassium.
It is important to get regular health checks, which include annual physicals and lab tests. These tests can help you identify any heart issues that could cause your PVCs. Also, you should not smoke and adhere to an appropriate diet plan. This can increase the frequency of episodes.
A survey of healthcare workers on 14 wards of a normal hospital showed that they were generally aware of the preventive measures for infections caused by vascular catheters however, their self-assessment of compliance with these guidelines was not great. The compliance improved following feedback interventions however it was still very low on some of the wards that were surveyed. This suggests that education is required on how to implement preventive measures, and those wards that are less compliant need to be targeted for monitoring of infection. This information can be used to guide the implementation of further quality improvement initiatives on these wards. This will most likely require additional education and training of personnel. It is also necessary to ensure that the appropriate tools for implementing the preventive measures are available.
Signs and symptoms
Involuntary ventricular contractions that are premature can cause your heartbeat to skip beats or flutter. These arrhythmias may be harmless, or they could indicate you are suffering from serious heart issues.
In healthy individuals, PVCs that occur occasionally are not an issue. They usually disappear by themselves. If you've got a lot of them, it could cause dizziness or weakness. Speak to your doctor if you are concerned. They might need to diagnose the problem by taking an medical history and performing an examination. They'll likely also need to perform an electrocardiogram (ECG or EKG) or other tests.
An ECG is a test that's quick that lets your health care provider see the signal from your heartbeat as it moves through your heart for an extremely short period of time. If you have PVCs, they'll show up in the test. Your doctor might also want to perform an overnight or 24-hour Holter monitor, which records your heartbeat for longer periods of time. This can help distinguish PVCs from other arrhythmias that cause heart palpitations. You might also be wearing a device that can record your heart rhythm over the course of 30 days, which is known as an event monitor.
Other tests for your heart might be required, depending on the reason for your PVCs. A cardiologist can check your blood pressure or conduct an echocardiogram (ultrasound of the heart). These tests can reveal if you have a issue that could be causing your PVCs or heart valves, such as cardiomyopathy, mitral valve prolapse or heart failure.
Your doctor may also have to run an examination of your blood to determine what is wrong with your electrolytes like low potassium or high calcium levels. This could be an indication of PVCs or other conditions that could cause them, including anxiety disorders and anemia.
You may be referred to a specialist in electrophysiology, who is able to treat abnormal heart rhythms. If you have structural heart disease the doctor may need to do other tests, like an MRI or CT scan of your chest. These tests can determine if your heart is damaged and the severity of the damage. In some instances an expert may recommend a pacemaker to treat the condition which is causing the PVCs.
