Electroencephalography Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used such as in electrocorticography. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain. In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp.

What is a Ventriculostomy? 10 hilariously insightful foreign words. A ventriculostomy involves the placement of a tube or catheter into fluid-filled spaces within the brain known as the ventricles. The tube typically goes into the part of the brain that contains the ventricles through a hole made in the top of the head.0 hilariously insightful foreign words.

Same generic drug, many prices We found big price differences at drug stores on the generic versions of Lipitor, Plavix, and other common drugs. Consumer Reports magazine: May 2013. If your insurance has ever stopped covering a prescription drug, or you don’t have coverage at all, you know how quickly costs can mount. Americans spent on average $758 out of pocket for medication in 2012, according to a recent Consumer Reports national telephone poll. And in our survey of 1,130 people who regularly took prescription drugs—the insured and uninsured—12 percent spent more than $1,200 last year.

Ventriculoperitoneal Shunt What Is a Ventriculoperitoneal Shunt? A ventriculoperitoneal (VP) shunt is a medical device that relieves pressure on the brain caused by fluid accumulation. VP shunting is a surgical procedure that primarily treats a condition called hydrocephalus. This condition occurs when excess cerebrospinal fluid (CSF) collects in the brain’s ventricles.

- Radiography is an imaging technique that uses electromagnetic radiation other than visible light, especially X-rays, to view the internal structure of a non-uniformly composed and opaque object (i.e. a non-transparent object of varying density and composition) such as the human body.uclear medicine typically involves gamma rays. The types of electromagnetic radiation of most interest to radiography are X-ray and gamma radiation. This radiation is much more energetic than the more familiar types such as radio waves and visible light.

- The ventricular system is a set of four interconnected cavities (ventricles) in the brain, where the cerebrospinal fluid (CSF) is produced.he ventricular system is continuous with the central canal of the spinal cord (from the fourth ventricle) allowing for the flow of CSF to circulate.

Ventricle (heart) Ventricle (heart) A ventricle is one of two large chambers in the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs. The atrium (an adjacent/upper heart chamber that is smaller than a ventricle) primes the pump.

cardiac monitor ballistocardiograph, cardiograph - a medical instrument that measures the mechanical force of cardiac contractions and the amount of blood passing through the heart during a specified period by measuring the recoil of the body as blood is pumped from the ventricles.

- An electrocardiogram (EKG or ECG) is a test that checks for problems with the electrical activity of your heart. An EKG shows the heart 's electrical activity as line tracings on paper. The spikes and dips in the tracings are called waves.

Electrocardiogram (ECG or EKG) An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart.

Echocardiogram What Is a Chest CT Scan? A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, is a painless, noninvasive test. It creates precise pictures of the structures in your chest, such as your lungs. Noninvasive means that no surgery is done and no instruments are inserted into your body. A chest CT scan is a type of x ray. However, a CT scan's pictures show more detail than pictures from a standard chest x ray.

Electrocardiogram (ECG or EKG) What is it? An electrocardiogram — abbreviated as EKG or ECG — is a test that measures the electrical activity of the heartbeat. With each beat, an electrical impulse (or “wave”) travels through the heart. This wave causes the muscle to squeeze and pump blood from the heart. A normal heartbeat on ECG will show the timing of the top and lower chambers.

Electrocardiogram (EKG/ECG) Electrocardiogram (EKG or ECG) is a medical examination that aims to monitor the heart. An electrical impulse triggers every heartbeat, and this electrical impulse comes from special cells that are present in the upper-right heart chamber.

Do Facial Exercises Work Just Like Plastic Surgery? Facial exercises don't give the same results as plastic surgery, although informational websites argue compellingly to the contrary. Facial exercises are unarguably a no-cost alternative to expensive cosmetic procedures, and they take only a few minutes of dedicated time. However, medical experts at the American Academy of Dermatology say the blink-squint-grimace repetitions you practice in front of the mirror each day only make matters worse.

Premature Ventricular Complexes - PVCs A PVC is an extra electrical impulse arising from one of the cardiac ventricles. Because this extra impulse appears before the next normal heart beat has a chance to occur, it is called premature. Read about the cardiac chambers. Read about the heart's electrical system. PVCs are diagnosed by observing them on an electocardiogram.

Myelography Myelography is an imaging examination that involves the introduction of a spinal needle into the spinal canal and the injection of contrast material in the space around the spinal cord and nerve roots (the subarachnoid space) using a real-time form of x-ray called fluoroscopy. Myelography is relatively safe and painless. 2  When a contrast material is injected into the subarachnoid space surrounding the nerve roots and spinal cord, it allows the radiologist to view outlines of the different areas of the spine that usually are not visible or distinguishable on x-rays.

- An electrocardiogram (ECG or EKG), is a measurement of the electrical activity of the heart. By placing electrodes at specific locations on the body (chest, arms, and legs), a graphic representation, or tracing, of the electrical activity can be obtained.n ECG is one of the simplest and fastest procedures used to evaluate the heart. An ECG technician, nurse, or physician typically will place 12 separate electrodes (small plastic patches) at specific locations on your chest, arms, and legs.

Echocardiogram This is an echocardiogram which involves the use of a contrast agent to help doctors evaluate blood flow and the heart cavity. The most common type of contrast echo is referred to as a bubble echocardiogram or bubble study.
