An electrocardiography and respiratory monitor recorder is provided. The recorder includes a sealed housing adapted to be removably secured into a non-conductive receptacle on a disposable extended wear electrode patch and an electronic circuitry comprised within the sealed housing. The electronic circuitry includes an electrocardiographic front end circuit electrically interfaced to an externally-powered micro-controller and operable to sense electrocardiographic signals through electrodes provided on the patch the micro-controller operable to execute electrically interfaced to one or more respiratory sensors provided on at least one of the patch and the sealed housing, the micro-controller further operable to sample the electrocardiographic signals and to sample respiratory events detected by the one or more respiratory sensors upon receiving one or more signals from the one or more respiratory sensors and an externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals and the respiratory events.
