Why the study?
Does a new statistical method for heart-sound processing based on average and variance calculation improve noise reduction and separation of heart sounds from murmurs in normal subjects and patients with cardiac pathologies?

A novel statistical method for heart-sound processing effectively separates deterministic heart sounds from murmurs and introduces 'jitter' as a new objective physiological parameter.
No takes yet. Share an insight, caveat, or question.
Jitter may serve as a novel objective parameter for heart sound variability; extends deterministic classifications but leaves clinical utility open.
Beyar et al. (1984) studied this question.
