We performed a retrospective analysis of 250 records of consecutive, newly implanted, pacemaker patients from a single center to determine the rate of postimplant complications and observations discovered before and during the prehospital discharge evaluation. No observations occurred in 246 of 250 patients (98.4%) (1-sided 95% confidence interval 96.4%). Of the 250 patients, 4 had observations that were discovered at the prehospital discharge check and required reprogramming to increase the sensitivity safety margin (3 atrial and 1 ventricular). We documented only 1 complication that was discovered before the predischarge evaluation through telemetry and resulted in an atrial lead revision.
Enhancing permeation in microfiltration (MF) hollow fiber membrane process was studied under ultrasound (US) by means of reflection technique. The US effect on the enhanced membrane process depended on the position of membrane module with or without a semi-cylindrical shaped reflection plate placed behind the membrane module. Evidence was presented that the membrane process influenced the detected sonic pressure distribution in the US bath. The correlation of sound pressure intensity and luminol fluorescence intensity suggested that violent collapse of cavity bubbles supported the enhanced membrane permeability of MF module in the US bath.
