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.

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.

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.

A plant moisture indicator is provided comprising a piece of wood cut across the grain with a moisture retardant substance applied to one side of the indicator, whereby the indicator will tend to bend in the presence of moisture and straighten up when dry. Preferably the device is constructed in the form of a U having two such opposed members, whereby the U will close in the presence of moisture and open in the absence of moisture.
