Why It's Important to See a Doctor Premature ventricular contractions (PVCs) are a form of irregular heartbeat. These extra beats are usually not dangerous and may be cured by themselves. Doctors will monitor your heartbeat and look for other vitals signs. They might order an Holter monitor which is a device that records your heart's electrical impulses over 24-48 hours. They can also order blood tests to check your thyroid and electrolyte levels. hormones. Diagnosis PVCs happen when electrical impulses from the lower chambers of the heart ventricles, or lower chambers, fail to pass through a structure called the SA node. This causes the heartbeat to be delayed, causing an experience of fluttering or skipped beats in the chest. PVCs can occur in a single pattern or in repeated patterns. Doublets are two consecutive PVCs. Ventricular tachycardia is three or more consecutive ones. Some people do not experience any symptoms, while others experience palpitations. It can be felt as an unsteady heartbeat or a rapid heartbeat. Other symptoms are dizziness, fatigue or a feeling that you're unwell. A lot of people who have occasional PVCs do not require treatment. If a patient is experiencing frequent episodes, a doctor may recommend a change to the diet or lifestyle. For example, limiting caffeine and stress as well as alcohol. the window doctors may also prescribe medications such as beta-blockers and calcium channel blockers, which can slow the heart rate and lower blood pressure. Doctors will ask about the person's medical history and do a physical exam to determine their general health. They may also use a Holter monitor to record the heart's rhythms over longer periods of time, or an electrocardiogram, which records a snapshot of the electrical activity within the heart. Doctors may order blood tests in certain cases to look for imbalances in electrolytes or drug toxicity. A pvc doctor might refer the patient to an electrophysiologist, or a specialist in heart rhythm disorders for further examination. The doctor can confirm the diagnosis of PVCs and determine if they are benign or malignant. PVCs are everywhere and aren't usually harmful unless they are used regularly or for a long period of time. This can cause weakening of the heart muscle, or a condition known as pvc-induced cardiomyopathy. It is more common in people who are older or those suffering from some type of heart disease. It can also occur in healthy people with a normal heart, although this is more likely for those who exercise regularly. It's not a serious problem, but it is important to inform your doctor if symptoms such as fatigue or fainting occur. Treatment For many people, sporadic PVCs may not cause any symptoms or require no treatment. If you notice that your heart is racing or skipping the beat, it's best to seek out a physician immediately. A cardiologist will first interview you and conduct an examination of your body by listening to your heart with the stethoscope in order to detect any irregular beats. You will also have an electrocardiogram (ECG) done that records the electrical impulses that occur in your heart and detect any arrhythmias. If an arrhythmia has been identified then an portable ECG or 24-hour Holter monitor is required to document the irregular rhythm for longer periods of time. These devices will help doctors determine if you have PVCs and the reason for them like an imbalance in electrolytes, toxic drugs or other causes. An echocardiogram, or an ultrasound of your heart, may be ordered to assess whether your heart is in good health and look for any indications of structural issues that could lead to PVCs. You might also have a stress test to see how your heart reacts to physical activity can increase the frequency of your PVCs. You may also be able to have blood tests to assess your thyroid, potassium, and magnesium hormone levels to determine whether they are insufficient and can cause the formation of PVCs. If your doctor has confirmed that you suffer from PVCs and has ruled any serious diseases out, the decision to treat them is based on the impact they have on 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 recommend any medication to lessen their frequency or severity. However, if you have frequent PVCs that do cause the sensation of palpitations or other symptoms, like lightheadedness or feeling like you're about to faint, your physician might suggest medication, such as beta blockers or calcium channel blockers. Changing your lifestyle to stay clear of triggers, such as caffeine, smoking and excessive stress, can also help lower the number of instances of these irregular pulses. Prevention PVCs can cause no symptoms or heart palpitations which may be described as “skipped beats” or flutters in your chest. Sometimes, these episodes cause a fullness or pressure in the chest. Other times they can make someone feel faint. These episodes result from the heart not pumping as efficiently as it should. PVCs are linked to an increased chance of developing dilated cardiomyopathy. This is a condition where the heart becomes enlarged and unable to pump blood. PVCs often are caused by changes in the body's chemistry. These include the release of thyroid and adrenaline hormones, in addition to 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. They can, for example, avoid foods that are preservative-laden, which can disrupt the heart rhythm. These include disodium Guanylate, disodium Inosinate, and diazole sodium (E282-283). Consume more fruits and vegetables to get sufficient magnesium. It is essential to have regular health checks, including annual physicals and laboratory tests. These tests can help identify any heart issues that could 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 typical hospital wards revealed that healthcare workers were generally aware of preventive measures against the infection caused by vascular catheters, but their self-assessment of conformity to these procedures was not high. The compliance improved following feedback interventions however it was still very lower on some of the wards surveyed. This suggests that training is needed on how to implement preventive measures, and that wards that are less than compliant should be targeted for infection monitoring. This information can then be used to guide the implementation of additional quality improvement initiatives for these wards. This could involve further training and education for personnel. It will also mean making sure that the correct materials are available for the implementation of preventive measures. Signs and symptoms If you feel that your heart beats are erratic or fluttering, it could be a sign of premature ventricular contractions. These arrhythmias could be harmless, or they could indicate you are suffering from serious heart issues. In healthy people, occasional PVCs aren't an issue and they generally disappear on their own. If you're suffering from several of them, they may cause dizziness or weakness. Talk to your doctor if you are concerned. You may need to give a medical history, and they may also conduct an examination of the body to diagnose the problem. They'll also probably want to do an electrocardiogram (ECG or EKG) or other tests. An ECG is a quick test that allows your health care provider see the signal from your heartbeat as it travels through your heart in a short period of time. The test will show whether you have PVCs. Your doctor may also suggest to do a 24- or 48-hour Holter monitor, which records your heartbeat for longer durations of time. These can help differentiate PVCs from other arrhythmias which cause heart palpitations. You can wear an event monitor, a portable device which records your heart rhythm for 30 days. Other heart tests may be required, depending on the reason for your PVCs. For instance a cardiologist could check your blood pressure, and also perform an ultrasound of your heart (echocardiogram). These can help find the presence of a medical condition that is responsible for your PVCs, such as mitral valve prolapse, cardiomyopathy or heart failure. Your doctor might also need to conduct an examination of your blood to determine what is wrong with your electrolytes, for example, low potassium levels or high levels of calcium. This could be a sign of PVCs or other conditions that can cause them, like anxiety disorders and anemia. You may be referred a specialist in electrophysiology, who treats abnormal heart rhythms. The doctor may be required to conduct additional tests if you have heart problems that are structural like an CT or MRI scan of your chest. These tests will determine if your heart is damaged and how severe it is. In certain cases, a specialist might suggest the use of a pacemaker or ICD to treat the underlying condition that's creating your PVCs.
