摘要: Disclosed examples include heart rate monitor systems (100) and methods to estimate a patient rate, in which processor (108) filters digital photoplethysmogram (PPG) sample values (107) representing transmission or reflection of light signal (121) (120) during time window, performs motion compensation processing on the filtered (213), computes gain value (Ki) for individual segments window using compensated (215), applies (215) blocks associated with corresponding segments, determines (221) according frequency content adjusted (217).
