Filed:

Nov 12, 1991

Appl. No.:

7/790500

Inventors:

Stuart L. Gallant - Owings Mills MD

Walter E. Palmer - Catonsville MD

Assignee:

Stuart Medical Inc. - Owings Mills MD

International Classification:

A61B 503

US Classification:

128700

Abstract:

An ambulatory patient monitoring system (100) is provided for measuring and storing predetermined diagnostic parameters of a patient. The monitoring system includes a personal type computer (120) which may be selectively coupled to the portable portion (102) of system (100). Portable portion (102) may include one or more monitoring modules, such as ECG monitoring unit (110) and blood pressure monitoring unit (210). When ECG monitoring unit (110) and blood pressure monitoring unit (210) are disposed in side-by-side relationship and with respective optical interfaces (50, 254) in optical alignment, the two units operate in concert. ECG monitoring unit (110) supplies an R-wave gating signal to blood pressure monitoring unit (210) for establishing a window in which the receipt of a Korotkoff sound is expected. Additionally, the ECG unit (110) may trigger the blood pressure unit (210) to take a reading responsive to unit (110) identifying a predetermined abnormality in the ECG signal. Alternately, ECG monitoring unit (110) and blood pressure monitoring unit (210) may be used independently of one another as separate monitoring devices.

International Classification:

G06F 1542

US Classification:

364417

Abstract:

An automatic high speed Holter scanning system operates in a nonautomatic mode or in an automatic mode to receive electrocardiogram signals which have been prerecorded in dissimilar formats having different known parameters, and to process same in accordance with an operator input. The automatic arrhythmia processor of the present invention detects ectopic cardiac information, stores the detected information in time sequence, and selectively reads out and displays the stored ectopic information in response to operator command. In addition, the automatic arrhythmia processor compares QRS complexes in received ECG signals to a desired normal QRS complex, and continuously updates the R-R interval and area of the normal QRS complex following each comparison of the normal QRS complex with the subsequent QRS complexes. The system of the present invention basically comprises a front panel for operator control, an input interface unit, converter unit, freeze memories with freeze memory control, CRT with CRT control, a chart recorder, an arrhythmia detection and scanning system, a central processing unit, and various front panel lamps and indicators.

Assignee:

Quinton Instrument Company - Seattle WA

International Classification:

A61B 50436

US Classification:

128711

Abstract:

A Holter-type recorder unit for use with an ambulatory ECG recording system is described. The invention features real-time beat differentiation, including ST analysis and paced beat analysis of two or three channel sampled electrocardiogram data. The invention also features real-time coding of beat morphology and summary information on cassette tape. Further, summary information for an entire analysis can be compiled and reverse recorded onto the cassette tape at the end of the analysis to allow downloading thereof into an ECG scanner while the cassette is being rewound.

Appl. No.:

6/174271

Assignee:

Hittman Corporation - Columbia MD

International Classification:

A61B 504

US Classification:

128710

Abstract:

An improved electrocardiography system displays and records electrocardiograph (ECG) signals provided on multiple pickup leads attached to a patient. The system has the capability of selectively displaying standard preprogrammed lead configurations or lead groups, and provides the operator with the additional capability of programming selected leads from various groups to form a "monitor group". Selected ECG signals are routed to a four-channel oscilloscope and a three-channel strip-chart recorder, the system providing the operator with a "freeze" capability such that a signal appearing on one of the oscilloscope channels may be displayed in a stationary state on the fourth oscilloscope channel, and subsequently printed out on the strip chart recorder. The system further provides an "auto lead" capability for fully automated successive recording of test data from leads in successively accessed conventional lead groups, and further provides an "auto cycle" mode of operation for fully automated repetitive recording of test data from selected leads for operator-designated recording times and at operator-designated time intervals.

International Classification:

G06F 1500

US Classification:

36441306

Abstract:

An ECG analysis system for use in conjunction with an ambulatory ECG recorder. The invention includes a playback deck which is capable of receiving and downloading information from a cassette tape to a dedicated digital analysis unit. The playback deck is capable of receiving information from the cassette tape during rewind of the tape therein as well as during playback of the tape. The dedicated digital analysis unit includes a superimposition template and a minute-by-minute ECG template which allow interaction between the dedicated digital analysis unit and the operator for simplification of analysis, manipulation, editing, and report generation. The system is capable of processing information from a cassette tape while it is being rewound in the playback deck and producing preliminary summary report information related to ECG data on the tape for use by a system operator before the tape completes its rewind operation. The playback deck also includes separate analog and digital circuit boards for isolating digital analysis operations from analog data manipulation operations and a speed control system for monitoring and correcting playback speeds of the tape in the playback deck.
