An ECG analysis system is provided that automatically scans and classifies in sequence a plurality of long term recorded patient cassette tapes by first identifying and then inserting each tape cassette into a cassette player for the analysis system, and finally removing each tape cassette from the analysis system once the analysis is complete. The system includes bar code reading and writing devices that are integrated with the analysis system to positively identify the patient associated with the tape recording. An automatic multiple cassette loader is disclosed wherein an elongated, rigid transport member having a transport slot cut along a substantial portion of its longitudinal axis is used to guide a detent armature, driven by a worm drive, in placing cassettes within a cassette player. The detent armature protrudes through said transport slot and pushes a single cassette out from the bottom of a stack of cassettes along the longitudinal axis of the transport slot and into the cassette player. Cassette removal is accomplished by a pair of jointed members coupled to motor means and a release mechanism within the playback means to eject the cassette from the playback means at a predetermined time. A pair of armatures are rotatably attached to the placement means for removing the ejected cassette from the playback means. A bay is provided into which the analyzed tape cassettes are automatically stacked.

A time saving automatic screening system for detection, measurement, analysis and plotting of electrocardiographic (ECG) signals employing arrhythmia analysis programs on long term ambulatory (Holter) recordings to assess the ECG signals and categorize the recorded data as either artifact, ventricular ectopic, superventricular ectopic, unknown or normal and to calculate a level of confidence that the category as chosen is a correct assessment. A system is disclosed that thresholds the occurrences of each category as well as the level of confidence to determine if significant abnormalities have occurred in the recording process, the hearts arrhythmia, or the heartbeat morphology. The method and apparatus disclosed make it possible to identify and screen out entire long term (Holter) ECG recordings containing no significant abnormalities in the hearts arrhythmia or the beat morphology. Thus, the cost of Holter scanning is greatly reduced by reserving for manual scanning only those recordings that contain significant abnormalities in the hearts arrhythmia or the beat morphology.
