Why It's Important to See a Doctor Premature ventricular contractions (PVCs) are a kind of irregular heartbeat. These extra beats aren't usually risky, and they may disappear by themselves. Doctors will listen to your heartbeat and look for other vital indicators. They might recommend an Holter monitor which records your heart's electrical impulses over 24-48 hours. They can also request blood tests for checking your thyroid hormones and electrolyte levels. Diagnosis PVCs occur when electrical impulses coming from the lower chambers of the heart ventricles misfire through a structure referred to as the SA node. This causes the next heartbeat to be delayed, causing the sensation of fluttering or skipped beats. PVCs can be seen in a single pattern or in repeated patterns. Two consecutive PVCs are referred to as doublets. Three or more consecutive PVCs are referred to as the condition known as ventricular tachycardia (VT). Some people are not experiencing any symptoms, whereas others experience heart palpitations. This can feel like an unsteady heartbeat or a slurred heartbeat. Other symptoms that are common are fatigue and dizziness, as well as a feeling of being sick. Many people who suffer from occasional PVCs do not require any treatment. If a patient is experiencing frequent episodes, a physician might suggest a change in diet or lifestyle. For instance, limiting caffeine, stress, and alcohol. They may also prescribe medications, such as beta-blockers and calcium channel blockers that can reduce the heart rate and lower blood pressure. Doctors will ask about the medical history of the patient and conduct a physical exam to assess their general health. They may also employ an electrocardiogram (ECG) to get an image of the heart's electrical activity, or a Holter monitor, which is worn for longer durations and records the heart's rhythms over time. In some cases doctors may require blood tests to determine if there is an electrolyte imbalance or toxic effects from drugs. A pvc doctor might refer a patient to an electrophysiologist or a specialist in heart rhythm disorders for further examination. This doctor can confirm the diagnosis of PVCs and determine whether they are benign or not. PVCs are fairly common and don't usually cause any problems unless they occur frequently over a long time. This could lead to a weakening of the heart muscle or a condition called pvc-induced cardiomyopathy. This is more prevalent in older adults or those suffering from heart disease. It can also occur in healthy people with an uninvolved heart, however this is more likely in those who exercise regularly. Usually, this isn't a serious concern however it is crucial to speak with a doctor if you notice symptoms like fainting or fatigue. Treatment PVCs are not harmful or cause any symptoms in the majority of people. They don't require treatment. If you notice that your heart is racing or skipping a beat, it's best to consult a doctor immediately. A cardiologist begins by interviewing you and doing an examination of your body, monitoring your heart using an stethoscope to detect any irregular heartbeats. You will also undergo an electrocardiogram that records the electrical signals of your heart, allowing you to identify any arrhythmias. If an arrhythmia has been identified, an portable ECG or a 24-hour Holter monitor will be required to capture the irregular rhythm for longer periods of time. These devices can help doctors determine whether you have PVCs and the underlying cause for them, like an electrolyte imbalance, a drug toxicities, or any other cause. An echocardiogram, or an ultrasound of your heart, can be ordered to determine whether your heart is healthy and check for signs of structural problems that can lead to PVCs. You might also have a stress test to see how your heart responds to exercise, as physical exercise can increase the frequency of your pvcs. window doctor can also have blood tests to determine your thyroid, potassium, and magnesium hormone levels to determine if they are too low, which can contribute to the development of PVCs. After your doctor has confirmed that you suffer from PVCs and has eliminated any serious illnesses, the decision on how to treat them will be contingent on how much they're impacting your life and the frequency at which they occur. If they only occur occasionally and do not cause symptoms then your doctor is unlikely to recommend any treatment to decrease their frequency or severity. If you experience frequent PVCs that can trigger pulses or other symptoms, such as feeling light-headed or fainting, your doctor may prescribe medications such as beta blockers and calcium channel blockers. Changes in your lifestyle, like avoiding caffeine, smoking and stress levels that are excessive can also decrease the frequency of these abnormal pulses. The following is a list of preventions. A person may experience no symptoms whatsoever from PVCs or experience heart palpitations (irregular heartbeats) that can feel like "skipped" beats or a fluttering sensation in the chest. These episodes can create a feeling of pressure or fullness or they can make you feel faint. These episodes occur because the heart is not pumping as effectively as normal. Frequent PVCs increase the risk of developing dilated Cardiomyopathy, a condition where the heart gets larger and is not able to pump blood. PVCs are often caused by changes in body chemistry. This includes the release of adrenaline and thyroid hormones, in addition to drinking alcohol or caffeine. Stress or weight gain, as well as an insufficient amount of exercise can trigger these episodes. Certain people find that changing their diet can reduce PVCs. They can, for example, avoid foods that contain preservatives which could cause disturbances to the heart rhythm. These include disodium Guanylate, diazole, and disodium inosinate sodium (E282-283). You can also consume more fruits and vegetables to ensure they're getting enough magnesium and potassium. It is essential to have regular health checks, which include yearly physicals and lab tests. They can aid in identifying any underlying heart conditions which could be causing your PVCs. You should also not smoke and adhere to a healthy diet program. This can increase the frequency of episodes. A survey of healthcare workers on 14 normal hospital wards showed that they were generally aware of the preventive measures that could be used to treat vascular catheter-associated infections However, their self-assessed compliance with these guidelines was not great. Compliance improved following feedback interventions however, it was still low on a few of the observed wards. This suggests that education on how to implement preventive measures is necessary and that wards which are less compliant should be targeted for infection surveillance. This information can be used to help in the implementation of quality improvement initiatives for these wards. This could involve additional education and training for personnel. It will also require making sure that the right materials are in place for the implementing of the preventive measures. Signs and symptoms If you feel your heart beats are erratic or fluttering, it could be a sign of premature ventricular contractions. These arrhythmias can be normal, or they could be a sign that you have heart issues that are serious. In healthy people, PVCs that occur occasionally are not an issue. They usually disappear on their own. If you're suffering from a lot of them, they may lead to dizziness or weakness. If you're concerned, talk to your doctor about the symptoms. They may have to identify the problem by taking an history of your medical condition and giving you a physical exam. They might also conduct an electrocardiogram or other tests. A quick ECG test allows your doctor to see the pulse of your heart going through your body over a a short period of time. If you have PVCs, they'll show up on the test. Your doctor may also recommend a Holter monitor that tracks your heartbeat over a longer period of time. These tests can help differentiate PVCs from arrhythmias that cause heart palpitations. You could also be wearing a device that records your heart's rhythm over the course of 30 days, which is known as an event monitor. Other heart tests may be required, based on the cause of your PVCs. For example an cardiologist may test your blood pressure and perform an ultrasound of the heart (echocardiogram). These tests can tell if you suffer from an issue such as heart failure, mitral valve prolapse, or cardiomyopathy. Your doctor might also need to conduct an analysis of your blood to determine what the problem is with your electrolytes, for example, low potassium levels or high calcium levels. This can be an indication of PVCs or other conditions that could cause them, like anemia and anxiety disorders. You may be referred an electrophysiologist who can treat irregular heart rhythms. The doctor may be required to conduct other tests if you are suffering from heart problems that are structural like an CT or MRI scan of your chest. These tests will help determine whether your heart is damaged and how severe the damage is. In some instances, the doctor might suggest the use of a pacemaker or ICD to treat the underlying issue the cause of your PVCs.
