Why It's Important to See a Doctor
Premature ventricular contractions (PVCs) are a form of irregular heartbeat. These extra beats are generally not dangerous and may go away by themselves.
To diagnose PVC doctors listen to your heartbeat and look for other vital signs. They may also order an Holter Monitor that records the electrical impulses generated by your heart over a period of between 24 and 48 hours. They may also order blood tests to check your thyroid hormones and electrolyte levels.
Diagnosis
PVCs are caused by electrical impulses that misfire through the SA node, a structure found in the lower chambers of the heart. This delay the next heartbeat and causes an experience of fluttering or skipped beats in the chest. PVCs can be seen as a single event, or in repeated patterns. Two consecutive PVCs are known as doublets, whereas three or more consecutive PVCs are referred to as the condition known as ventricular Tachycardia (VT).
Some people don't experience any symptoms whatsoever Others experience heart palpitations that can be felt as an irregular heartbeat or a pounding. Other symptoms that are common are fatigue, dizziness or a sensation of being sick.
Many people who suffer from occasional PVCs do not require any treatment. If a patient experiences frequent episodes, a doctor may recommend a change to diet or lifestyle. For instance restricting caffeine and stress as well as 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 person's medical history and do a physical exam to check their general health. They may also use a Holter monitor to record the heart's rhythms over longer durations, or an electrocardiogram, which records a snapshot of the electrical activity within the heart. In some cases doctors may request blood tests to look for an electrolyte imbalance or toxic effects from drugs.
A pvc physician may refer a patient to an electrophysiologist or specialist in heart rhythm disorders for further examination. This doctor can confirm the diagnosis of PVCs and determine if they are benign or not.
PVCs are frequent and usually don't cause any problems unless they occur frequently over a long time. This could lead to a weakening of the heart muscle, or a condition referred to as pvc-induced cardiomyopathy. It is more common for people over the age of 65 or those with some form of heart disease. It can also occur to healthy people who have normal, normal heart. However, it is more prevalent among those who regularly exercise. Most of the time, this isn't a serious concern however it is crucial to tell an expert if you notice symptoms like fainting or fatigue.
Treatment
PVCs aren't harmful or cause symptoms in many people. They don't require treatment. However, for those who do experience a sensation like your heart is lagging a beat or is racing, it's important to consult a physician as soon as you can.
A cardiologist will interview you and conduct physical examinations, listening to your heart through a stethoscope to detect any irregular heartbeats. You'll also get an electrocardiogram (ECG) done, which will record the electrical impulses that occur in your heart and identify any arrhythmias. If an arrhythmia is identified, you will require a 24-hour Holter monitor or another portable ECG will be needed to record the irregular rhythm over longer durations of time. These devices will help doctors determine whether you have PVCs and the reason for them, such as an imbalance in electrolytes, toxic drugs or other factors.
You might be requested to undergo an echocardiogram (an ultrasound of your heart) to determine the health of your heart is good and to look for structural issues which could lead to PVCs. You may also be asked to take an exercise test to determine how your heart reacts to exercise. Exercise can increase your frequency of pvcs. You can also get blood tests to test your thyroid hormone as well as potassium, magnesium, and other hormones to determine if they're too low. This can lead to PVCs.
If your doctor confirms that you have PVCs, and has ruled any serious illnesses out, the treatment you choose to take depends on how they impact your life and how frequently they occur. If they only occur occasionally and do not cause symptoms, your doctor is unlikely to prescribe any medication that will reduce their frequency or severity.
If you experience frequent PVCs, which can cause pulses or other symptoms, like feeling lightheaded or fainting, your doctor might prescribe medications like beta blockers and calcium channel blockers. Changes in lifestyle, like avoiding caffeine, smoking and stress levels that are excessive can also 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 experience heart palpitations (irregular heartbeats) that may feel like "skipped" beats or fluttering in the chest. These episodes can create feelings of fullness or pressure, or they may cause you to feel faint. These episodes result from the heart not pumping as efficiently as it should. Frequent PVCs increase the chance of developing dilated cardiomyopathy. a condition wherein the heart gets larger and becomes ineffective at pump blood.
PVCs are usually caused by changes in the body's chemical chemistry. This is due to the release of adrenaline and thyroid hormones as well as drinking alcohol or caffeine. Lack of exercise can also trigger these episodes, as can stress or excessive weight.
Some people find that changing their diet may help to reduce the amount of PVCs. For example, they can avoid foods that contain preservatives that can cause a disturbance to the heart rhythm, such as disodium guanylate (E621), disodium inosinate (E627) and diazole sodium (E282-283). Eat more fruits and vegetables to get sufficient magnesium.
It is important to get regular health check-ups, which include annual physicals and lab tests. These can help diagnose any heart-related conditions which could be causing your PVCs. Also, you should adhere to an eat-healthy diet and avoid smoking, which could increase the frequency of your episodes.
A survey of healthcare staff on 14 normal hospital wards found that they were mostly aware of the preventive measures that could be used to treat vascular catheter-related infections however, their self-assessment of compliance with these guidelines was poor. After a feedback intervention that improved compliance on certain areas, but was still very low. This suggests that education on how to implement the preventive measures is necessary and that wards which are less compliant should be targeted for infection surveillance. These data can be used to guide quality improvement initiatives in these wards. It is likely that this will require more education and training for personnel. It will also involve making sure that the right tools are available for implementing of the preventive measures.
Signs and symptoms
The premature contraction of the ventricular muscle can cause your heartbeat to skip or flutter. These arrhythmias aren't necessarily dangerous or they can be an indication of serious 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, they can cause dizziness or weakening. If you're worried about them, consult your doctor about them. They may have to identify the issue by taking an history of your medical condition and conducting a physical exam. They may also want to conduct an electrocardiogram or other tests.
double glazing doctor will allow your doctor to observe the heartbeat signal moving through your body for a the course of a brief period. If you have PVCs, they'll show up on the test. Your doctor may also recommend the use of a Holter monitor that records your heartbeat for a longer period of time. These tests can help distinguish PVCs from arrhythmias causing heart palpitations. You may also carry a device that records your heart rate over the course of 30 days, which is known as an event monitor.
Other tests for your heart might be required, based on the reason for your PVCs. A cardiologist can check your blood pressure or perform an echocardiogram (ultrasound of the heart). These tests can determine whether you are suffering from a condition such as heart failure or mitral valve prolapse or cardiomyopathy.
Your doctor may also be required to run an analysis of your blood to determine what the problem is with your electrolytes such as low potassium or high calcium levels. This could be a sign of PVCs or other conditions that may cause them, including anxiety disorders and anemia.
You might be directed to an electrophysiologist, one of the specialists who specialize in treating irregular heart rhythms. If you have structural heart disease, this specialist might need to conduct additional tests, like an MRI or CT scan of your chest. These tests can determine if you have damage to your heart and how serious it is. In some instances, the doctor may suggest the use of a pacemaker or ICD to treat the underlying issue creating your PVCs.
