Labetalol for hypertensive pulmonary oedema in pregnancy

摘要

We wish to describe a novel method for assessing the regularity of electrocardiogram (ECG) rhythms.When viewed correctly, random dot autostereogram images provide an illusion of depth perception from a two-dimensional source, and were popularised in the 1990s as 'Magic Eye puzzles' (Magic Eye Inc., Prov-incetown, MA, USA; Fig 1). They contain repeating patterns that the viewer can train him/herself to overlap by forcing a divergent gaze.
