Records in the MIT-BIH Arrhythmia Database

This section contains notes and statistics that describe the contents of each record. The leads used for the upper and lower signals are given for each record immediately following the record number. Beat counts are given for the first five minutes of each record and the remainder of the record (the EC38-defined ``learning'' and ``test'' periods, respectively). Note that the totals include two types of non-beats (blocked APCs and ventricular flutter waves) for those few records in which they occur. The total duration of each record is 30 minutes and 5.556 seconds; durations noted below are rounded to the nearest second, and may not sum to exactly 30:06 because of accumulated rounding error. Heart rates are given in beats per minute measured over 3 R-R intervals.

Following the statistical summary and notes for each record are links to points of interest in each case. You may follow these links to view the signals and annotations using WAVE. To do so successfully, you must have configured your browser to use wavescript as a helper application, as described in WAVE and the Web (in the WAVE User's Guide).

Notes:

This is an extremely difficult record. The predominant rhythm is normal sinus with first degree AV block and left bundle branch block. There are periods when the conduction block changes to a right bundle branch block pattern. The PVCs are multiform. Idioventricular rhythm appears following the longest episode of ventricular flutter. The record ends during the episode of SVTA.
