SUMMARY NOTES IN THE RECORD s20161 (Duration: 23:44:01.000)
Starting time, recording date: 14:36:00 01/12/1986
Lead 0: MLIII
Lead 1: V4
Age: 65 Sex: M
Comments:
This patient has Prinzmetal's angina, with episodes of
major ST elevation in lead 0. In lead 1 the corresponding
changes are ST depressions. Of interest, the QRS morphology
changes slightly during the ischemic episodes, possibly
due to transient chamber enlargement (Bradie effect). The
time course of the morphology change is gradual, as opposed
to the sudden axis shifts characteristic of postural
changes.
An excerpt of this recording is included in the European
ST-T Database (record e0105).
