Orphan date September 2008 A Lewis Lead also called the S5 lead is a modified EKG lead used to detect atrial flutter waves when atrial flutter is suspected clinically but not definitely demonstrated on the standard 12 lead EKG. In order to create the Lewis Lead, the right arm electrode is moved to the right, second intercostal space adjacent to the Human sternum sternum . Then the left arm electrode is moved to the right, fourth intercostal space adjacent to the sternum. The Lewis Lead is then read as Lead I on the EKG and, since in most patients it will be roughly perpendicular to the wave of atrial depolarization , flutter waves may be more apparent.

COEKG advocates expect their experience will assist in the standardization of more general electronic medical records EMR data exchange. COEKG implements a subset of the Continuity of Care Record CCR messaging protocol. When fully connected health care consumers and providers will be able to securely and reliably access point of care clinical information. Many providers and patients advocate rapid development of EMR interconnectivity, and they believe COEKG efforts should expand to the entire health record. Critics denounce the idea for fear that privacy protection will never reach an acceptable level.

File Motorola Apcor Header Wiki.jpg 300px thumb right White Motorola APCOR Paramedic Voice Ekg Telemetry Radio Late 1970s The Motorola APCOR was a 12 watt, paramedic telemetry radio produced by the Motorola company during the 1970s and the 1980s. The Motorola Apcor could transmit voice and EKG simultaneously and was battery operated. There were three or more versions of the Motorola APCOR, the first was similar to the Biophone , the 2nd was significantly smaller and was white. The third version of the Motorola APCOR was all white. The Motorola APCOR was discontinued in the 1980s and was soon phased out in favor of cellular phones that could transmit EKG and voice. Motorola mistakenly thought that the LA County Fire Department s code was for the radios to be orange, and created an orange radio for its first version. The radio had the Motorola MX 300 imbedded inside of the radio and had 10 MED channels. It was slightly ahead of the Biophone , in portability, but both had the same specifications. The APCOR became very popular during the late 70s and the 1980s and was widely adopted by fire departments and emergency medical services agencies across the United States. Some fire departments currently still use the radio, but many have been phased out and retired. The Motorola APCOR had a significant impact on paramedic history, as well as most importantly the Biophone .

Image EKG Asystole.jpg thumb 200px Flatlined Electrocardiogram ECG lead for other uses A flatline is an electrical time sequence measurement that shows no activity and therefore when represented, shows a flat line instead of a moving one. It almost always refers to either a flatlined electrocardiogram , where the heart shows no electrical activity asystole , or to a flat electroencephalogram , in which the brain shows no electrical activity brain death . Both of these specific cases are involved in various definitions of death . Some consider one who has flatlined to be clinically dead, regardless of eventual resuscitation or lack thereof, whereas others insist that one is alive until the moment of brain death. This is mostly used in the medical industry when a person s pulse has stopped, indicating a flat line on the heart monitor. When a patient displays a cardiac flatline, the treatment of choice is an injection of vasopressin epinephrine and atropine are also possibilities ref Caggiano, R. http www.emedicine.com EMERG topic44.htm E Medicine Asystole Retrieved on 2008 11 13. ref and chest compressions . Successful resuscitation is generally unlikely and is inversely related to the length of time spent attempting resuscitation. Despite defibrillation commonly appearing on medical dramas as a remedy for asystole, it is usually not done when there is a total absence of electrical activity, as it could actually make it more difficult to restart the heart. A flatline will also be generated if all leads are disconnected from the patient. References Reflist Category Medical tests ... more details

A Driven Right Leg Circuit or DRL circuit is an electric circuit that is often added to biological signal amplifiers to reduce Common mode interference . Biological signal amplifiers such as EKG Electrocardiogram EEG Electroencephalogram or Electromyography EMG circuits measure very small electrical signals emitted by the body, often as small as several micro volts millionths of a volt . Unfortunately, the patient s body can also act as an antenna which picks up electromagnetic interference , especially 50 60 Hz noise from electrical power lines. This interference can obscure the biological signals, making them very hard to measure. Right Leg Driver circuitry is used to eliminate interference noise by actively canceling the interference. Other methods of noise control include Faraday cage Twisted pair Twisting Wires High Gain Instrumentation amplifier Instrumentation Amplifier Filtering Further reading IEEE Citation format ISBN added br 1 J.G.

Orphan date February 2009 Regarding cardiology and conduction characteristics Tissue stimulation without direct effect such as causing contraction in another chamber , but leading to a change in conduction characteristics. A common example would be an interpolated PVC a type of premature ventricular contraction during normal sinus rhythm the PVC does not cause an atrial contraction, because the retrograde impulse from the PVC does not completely penetrate the AV node. However, this AV node stimulation which is not visible on EKG by itself, hence concealed can cause a delay in subsequent AV conduction by modifying the AV node s subsequent conduction characteristics. Hence, the P R interval after the PVC is longer than the baseline P R interval. Another variation on this concept is seen in atrial flutter . As a result of the rapid atrial rate, some of the atrial activity fails to get through the AV node in an antegrade direction but can alter the rate at which a subsequent atrial impulse is conducted. In this circumstance, an alteration in the F wave to QRS relationship is seen.

LIFESTAR is an aeromedical transport service of the University of Tennessee Medical Center that provides regional rapid transportation of injured patients. LIFESTAR transports approximately 200 patients per month. Fleet LIFESTAR s fleet consists of two Bell 430 medium twin helicopters, a Bell 206 L4, and a Bell 407. Both Bell 430 helicopters are equipped with all the features of a ground ambulance, with additions of 12 lead EKG s, and chemical blood analysis kits. The helicopters accommodate one FAA certified pilot, one flight paramedic, one flight nurse, and room enough for two patients. In the last few years, they have doubled their fleet with two Eurocopter EC135 helicopters. Bases LIFESTAR operates three bases with its main base is at the University of Tennessee Medical Center UT Medical Center , Knoxville. Additionally, bases are located in Sevier County, Tennessee at the Gatlinburg Pigeon Forge airport and Monroe County, Tennessee at the Sweetwater Fire and Rescue Station No. 2. One of the 2 helicopters is always based in Knoxville with the other rotating between the outlying bases. Activation Initiation of a LIFESTAR flight may come by way of medical or law enforcement personnel, initiated at either the accident site, or from a referring hospital.
