SAMPLE EXCERPT:

[. . .] Sample to the study enrolled 134 out-patients from 18 centers who had existing CRT-D systems with software capable of automatically executing LV threshold measurements. Measurements were downloaded into the random access memory (RAM) of the device. Reported outcomes to the study indicate that the algorithm measured the threshold successfully in 96% and 97% of patients after 1 and 3 months respectivel, with augmentation of the data derived from the Holter monitor analysis where a subset of the test subjects revealed accurate performance of the algorithm. The test supports the claim that the new CRT-D improved ability to maintain LV capture without sacrificing device longevity.

Objectives to the investigation to "(i) evaluate the feasibility and results of monitoring patients prior to and following catheter ablation of AF with the mobile cardiac outpatient telemetry (MCOT) system and to (ii) correlate symptoms and the presence or absence of atrial fibrillation (AF)" were designed to demonstrate the potential utility of wireless monitoring systems in the follow-up of AF patients. Of a total of 12/19 consecutive patients with (63%) age 60 ( ± 6 years) with highly symptomatic drug refractory AF underwent catheter ablation, each was provided with a MCOT monitor (CardioNet, USA) for a total of 494 days (11,856 hours) of monitoring. Termination of the study concluded at the end of the study with 6/10 patients completing the test. In those subjects (70%) patients were free of symptomatic AF recurrences compared to (50%) asymptomatic AF recurrences. Some identified poor patient compliance with an intensive monitoring protocol as an important limitation.

The researchers investigate the value of a miniaturized stent-based antenna system for use in wireless telemetry and power transfer for the implanted electronics. Reduced to an area of less than 1 mm2, with a thickness under 300 ?m, research studies implantation of a minimally invasive implantation procedure; allowing the delivery of the stent-based implant in nearly any major vessel of the body. Initial prototype with two stents "configured as a single dipole, a 2.4-GHz transmitter microchip and battery [that] validates transcutaneous transmission through ex-vivo and in vivo porcine" is described.

The stent-based antenna can be used in monitoring of blood pressure from a minimally invasive device inserted for tracking the pulmonary artery in diagnostic and early warning system for cardiac health. In cardiac diagnostics, the foremost challenge in using a like device is the wireless transfer of data and power from within the blood vessel to external devices; whilst maintaining unrestricted blood flow through the artery.

A three (3) inpatient nursing unit study on the implementation of a multidisciplinary approach to systematically decrease medication errors through the use of observation methodology and the deployment of electronic medication administration records (EMARs) and bar-coded-medication administration (BCMA) is discussed. Testing of two (2) intervention groups: 1) 20-bed cardiac control group in the telemetry unit; 2) a 36-bed medical-surgical unit. Testing was conducted utilizing a direct observation technique for data collection, the measurement of medication errors used the observation process was conducted in two (2) phases: 1) reimplementation; and 2) postimplementation. In the first phase of the study evaluating the medication administration process associated with a manual five (5) day medication administration record (MAR), a total of 188 errors were reported. During the second… [END OF PREVIEW]
