Why It's Important to See a Doctor Premature ventricular contractures (PVCs) are a type of irregular heartbeats. These extra beats are generally not dangerous and may be cured by themselves. Doctors will monitor your heartbeat and look for other vital signs. They may order a Holter Monitor that records the electrical impulses of your heart over a span of 24 to 48 hours. They may also order blood tests for checking your thyroid hormones and electrolyte levels. Diagnosis PVCs are caused by electrical impulses which misfire through the SA node, a structure found in the lower chambers of the heart. This delay the next heartbeat, causing a feeling of skipped beats or fluttering in the chest. PVCs can occur in one pattern or in repeated patterns. Doublets are two consecutive PVCs. Ventricular tachycardia is three or more consecutive PVCs. Some people do not experience any symptoms, but others experience palpitations. It can be felt as an unsteady heartbeat or a skipping heartbeat. Other symptoms that are common are fatigue or dizziness, or a feeling of being unwell. Many people who experience occasional PVCs do not require treatment. If a person has frequent episodes, doctors may suggest a change to the way of life or diet, such as limiting alcohol, caffeine and stress. They may prescribe medication such as beta-blockers or calcium channel blockers to lower blood pressure and slow the heart rate. Doctors will ask about the person's medical history and conduct a physical exam to check their general health. They may also use an electrocardiogram (ECG) to get an image of the heart's electrical activity, or a Holter monitor that is worn for longer periods and captures the heart's rhythms over time. In certain cases doctors may request blood tests to look for an electrolyte imbalance or drug toxicity. Sometimes, a pvc physician may refer a patient to a specialist for heart rhythm problems, or an electrophysiologist, for further evaluation. The doctor can confirm the diagnosis of PVCs and determine if they are malignant or benign. PVCs are quite frequent and usually don't cause any problems, except when they are frequent over a long period of time. This can lead to a weakening of the heart muscle or a condition referred to as pvc-induced cardiomyopathy. This is more common in older adults or those with heart disease. It can also occur to healthy individuals with normal, normal heart. However, it is more prevalent in people who exercise regularly. Usually, this isn't an issue that is serious however it is crucial to speak with your doctor if you experience symptoms such as fainting or fatigue. Treatment For many people, sporadic PVCs may not cause any symptoms or are harmless and require no treatment. However when you feel their heart has skipped an beat or is racing, it's vital to speak to a doctor as soon as you can. A cardiologist will begin by interviewing you and performing a a physical exam, monitoring your heart using an stethoscope to detect any irregular beats. You'll also undergo an electrocardiogram, which records the electrical signals of your heart to determine any arrhythmias. If window doctor is identified, an all-day Holter monitor or other portable ECG will be needed to record the irregular rhythm for longer periods of time. These devices can assist doctors determine if you suffer from PVCs and the reason for them like an imbalance in electrolytes, toxicity of drugs or other causes. An echocardiogram, also known as an ultrasound of your heart, could be ordered to determine if your heart is healthy and check for indications of structural issues which could cause PVCs. You may also be asked to undergo an exercise test to find out the response of your heart to exercise. Exercise can increase the frequency of pvcs. You may also undergo blood tests to determine your magnesium, potassium and thyroid hormone levels to determine whether they are low and can cause the formation of PVCs. Once your doctor has confirmed that you're suffering from PVCs and has ruled out any serious illness, the decision on whether to treat them will be based on the degree to which they're affecting your life and how frequently they occur. If they only occur occasionally and don't trigger any symptoms, it's unlikely that your doctor will suggest any medication to lessen their frequency or severity. If you are experiencing frequent PVCs that can trigger heart palpitations, or other symptoms like feeling lightheaded or fainting, your doctor might prescribe medications like beta blockers and calcium channel blockers. Lifestyle changes like cutting down on smoking, caffeine and stress levels that are excessive can also decrease the frequency of these irregular pulses. The following is a list of preventions. PVCs can cause no symptoms or heart palpitations, which can be described as "skipped beats" or flutterings in the chest. Sometimes, these episodes trigger the chest to feel full or swollen in the chest, and other occasions, they may make someone feel faint. These episodes are caused by the heart isn't pumping as efficiently as it normally does. Frequent PVCs increase the risk of developing dilated cardiomyopathy, a condition wherein the heart gets larger and is unable to pump blood. PVCs often are caused by changes in the body's chemical chemistry. This is due to the release of thyroid hormones and adrenaline as well as drinking alcohol or caffeine. Stress or excess weight or the absence of exercise can trigger these episodes. Certain people find that changing their diet can reduce the number of PVCs. For example, they can avoid foods that contain preservatives that can cause a disturbance to the heartbeat, for example disodium Guanylate (E621), disodium inosinate (E627), and diazole sodium (E282-283). Eat more fruits and vegetables to ensure that you get sufficient magnesium. It is essential to have regular health checks, including annual physicals and lab tests. These tests can help diagnose any heart issues that could cause your PVCs. Also, you should adhere to an appropriate diet and refrain from smoking, which can increase the frequency of your episodes. A survey of 14 typical hospital wards revealed that healthcare staff were generally aware of preventive measures against vascular catheter-associated infection, but their self-assessment of conformity to these procedures was not high. After a feedback intervention the compliance level improved on a few wards but was still low. This suggests that training is required to implement preventive measures, and those wards that are not compliant need to be targeted for infection monitoring. These data can be used to inform quality improvement initiatives in these wards. This will likely require further education and training for personnel. It will also mean making sure that the right tools are available for implementation of preventive measures. Symptoms If you feel that your heart is racing or fluttering, it may be a sign of premature ventricular contractions. These arrhythmias may be harmless or they may be a sign of serious heart issues. In healthy people, occasional PVCs aren't an issue and they usually disappear on their own. If you've got a lot of them, it can cause dizziness or weakening. If you're concerned about them, consult your doctor about them. You may need to give an medical history, and they might also perform an examination to determine the cause. They may also want to conduct an electrocardiogram, or other tests. A quick ECG test lets your doctor see the signal of your heartbeat going through your body over a a short period of time. The test will show if you have PVCs. Your doctor might also suggest a Holter monitor that records your heartbeat over a longer amount of time. They can help distinguish PVCs from other arrhythmias which cause heart palpitations. You can also wear an event monitor, which is a portable device that records your heart rhythm for 30 days. Other tests for your heart might be required, depending on the reason for your PVCs. A cardiologist may check your blood pressure or conduct an echocardiogram (ultrasound of the heart). These tests can tell whether you have an issue like heart failure or mitral valve prolapse or cardiomyopathy. Your doctor might also need to do an analysis of your blood to determine what's wrong with your electrolytes such as low potassium or high calcium levels. This can be a sign of PVCs or other conditions that may cause them, like anxiety disorders and anemia. You might be directed to an electrophysiologist, a specialist who specializes in treating heart rhythms that are abnormal. If you suffer from structural heart disease, this specialist might need to do other tests, like an MRI or CT scan of your chest. These tests will tell you whether you've damaged your heart and how serious it is. In some instances, the doctor may recommend an implantable pacemaker or ICD to treat the underlying condition that's the cause of your PVCs.
