Detection of sleep-disordered breathing with ambulatory Holter monitoring

Abstract

Holter-derived respiration detected OSA comparable to PSG. Further study is warranted to determine its utility for screening and diagnosing OSA in appropriately selected patients.

Noninvasive monitoring technologies to identify discomfort and distressing symptoms in persons with limited communication at the end of life: a scoping review

“…Traditionally, electrodes are attached to the torso and connected to a monitor. Among the manuscripts included in this review, the number of electrodes varied between 3 and 12, and the devices could be portable [ 74 , 75 ]. Heart rate data can also be extracted from smart watches [ 76 ].…”

“…Indices derived from ECG signals correlated with self-rated pain among patients taking physical therapy after surgery [ 74 ] and sleep apnea among people with suspected sleep disordered breathing measured by standard PSG [ 75 ]. When ECG indications of pain differed from observation, a recent study with patients under palliative sedation favored the ECG measurement and concluded that it was more objective [ 70 ].…”

ECG derived Cheyne–Stokes respiration and periodic breathing are associated with cardiorespiratory arrest in intensive care unit patients

“…10,38 More recently, this algorithm was compared by Grasso and colleagues to Polysomnography in a prospective cohort of patients being screened for obstructive sleep apnea. 39 The algorithm derives CSRPB episodes from continuously acquired ECG data by examining beat to beat changes in the QRS complex that occur when the heart shifts in the thorax during inhalation and are associated with an increase in tidal volume. The ECG algorithm computes mean square QRS amplitude variations in 15 second intervals (area divided by width in ¼ microvolts) and derives a mean QRS amplitude waveform at a rate of one sample per second, which is then used to measure changes in tidal volume and calculate CSRPB.…”
