Key result
Continuous 48-h 12-lead ST monitoring detected ischaemia in significantly more patients with unstable angina compared to 3-lead monitoring (77% vs 62%, P<0.02).

May refine ST monitoring protocols in unstable angina; leaves open impact on outcomes and management.
Observational (n=130)
Does continuous 12-lead ST monitoring improve the detection and quantitation of ischaemia compared to 3-lead ST monitoring in patients with unstable angina?
Absolute Event Rate: 77% vs 62%
p-value: p=< 0.02
Continuous 12-lead ST monitoring significantly increases the detection rate and duration of ischemic episodes compared to 3-lead monitoring in patients with unstable angina.
Klootwijk et al. (1997) conducted an observational in unstable angina (n=130). Continuous 48-h 12-lead ST monitoring vs. 3-lead ST monitoring was evaluated on Detection of ST episodes (ischaemia) (p=< 0.02). Continuous 48-h 12-lead ST monitoring detected ischaemia in significantly more patients with unstable angina compared to 3-lead monitoring (77% vs 62%, P<0.02).
