Abstract:
In a systemvalidation of a ambulatory EKG analysis system we examined the HP 43420A ambulatory EKG analysis system(Fa.Hewlett packard, USA). The complete capture module 43405A with the applied software is able to record 24 hours events without single beat lable. Model 43400B patient analyzer records intermittant the EKG events and represents these in the Ambulatory EKG report. By means of the devices 31 patients were examined. Beat-to-beat analysis of the complete full disclosure is visually carried out. Sensitivity and postitve predictive value were 94(96)% and 100% for ventricular ectopic beat(VEB). The sensitivity amounted to 87% in the detecting of VEB pair(couplet), the positive predictive value 94%. VEB Run/VT(ventriular tachycardia) resulted in a sensitivity of 82% and in positive predictive value of 93%. The automatically edited Ambulatory EKG report with his EKG strips is representative of full disclosure and reliable in comparison with the analyzed results of full disclosure. The HP 43420A Ambulatory EKG Analysis system, a new and developed device with all digital recording system and full disclosure capability is found comparable to the best ones of the presently available Holter monitoring system.
