The device detects the appearance of irregular heartbeat during measurement, and gives a warning signal once the irregular heartbeat is detected. ## Device Story Automatic Digital Blood Pressure Monitor (Models LD6, LD7) measures systolic/diastolic blood pressure and pulse rate. Device uses oscillometric method via inflatable upper arm cuff. Operates as over-the-counter device for adult self-use or clinical setting. Input: pressure oscillations from cuff. Processing: internal firmware detects pressure changes and identifies irregular heartbeats. Output: digital display of blood pressure values and pulse rate; visual warning signal for irregular heartbeat. Assists users in monitoring cardiovascular health status. ## Clinical Evidence Bench testing only. No clinical data provided. ## Technological Characteristics Non-invasive oscillometric blood pressure measurement system. Includes inflatable upper arm cuff, pressure sensor, and digital display. Powered by internal battery/power source. Firmware-based processing for pressure oscillation analysis and irregular heartbeat detection. ## Regulatory Identification A noninvasive blood pressure measurement system is a device that provides a signal from which systolic, diastolic, mean, or any combination of the three pressures can be derived through the use of tranducers placed on the surface of the body. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
