This document discusses screening for obstructive sleep apnea using electrocardiogram signals. It references a 2004 study that investigated the automated detection of obstructive sleep apnea at different time scales using the electrocardiogram. The document also discusses how obstructive sleep apnea has been associated with several cardiovascular diseases and how advanced holter monitoring can help treat arrhythmias by identifying obstructive sleep apnea as a potential cause.

OSA has been associated with several
cardiovascular diseases, most notably
hypertension, ischemic heart disease,
heart failure, stroke, cardiac arrhythmias,
and pulmonary hypertension.
