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.

Claims

1. A recorder for recording data tehted to analog ECG signals representing heart beat waveforms and morphological characteristics of the heart beat waveforms onto a tape comprising:

means for receiving analog ECG signals relating to heart beat waveforms,

analysis means capable of generating digital data relating to morphological characteristics of the heart beat waveforms, and

means for recording the analog ECG signals and said digital data relating to morphological characteristics onto the tape.
