Benefits of technology

This patented describes various technical improvements that help healthcare providers manage their patient's electrical pulse during treatment without losing vital organs like blood vessels due to sudden irregularities caused by abnormal electric signals from an electrocardiogram machine. These modifications aimed towards improving these treatments and enhancing their effectiveness over time.

Problems solved by technology

Technicians use implanted medical equipment like pacemakers/cardiostimulators to diagnose conditions related to poor blood flow caused by CHF symptoms that are difficult to manage effectively without surgery. However, current methods only measure specific parameters - either alone or together from multiple sources - making it challenging to accurately identify any changes made during these procedures.

Embodiment Construction

[0045] Disclosed herein are systems, devices, and methods for detecting arrhythmias, such as atrial tachyarrhythmia (AT). The representative ventricular heart rate can be detected from the physiological signal in the heart rate analysis window. The atrial tachyarrhythmia detector circuit can generate a first ventricular heart rate statistic from the representative ventricular heart rate determined in the first plurality of heart rate analysis windows, and from the second plurality of heart rate analysis windows during a specific duration One or more second ventricular heart rate statistics are generated from the determined multiple representative ventricular heart rates. In response to the second ventricular heart rate statistic meeting a specific condition throughout a specific duration, one or more types of sustained AT events may be detected.

Abstract

Systems and methods for detecting atrial arrhythmias such as atrial tachyarrhythmia (AT) are described herein. An AT detection system may include a heart rate detector circuit configured to detect, from a physiological signal, representative ventricular heart rates within heart rate analysis windows. An atrial tachyarrhythmia detector circuit may perform an initial rate detection using a first ventricular heart rate statistic generated from the representative ventricular heart rates, and to perform a sustained arrhythmia detection using one or more second ventricular heart rate statistics generated within a second plurality of heart rate analysis windows during a specific duration. An AT event is detected if the second ventricular heart rate statistics satisfy a specific condition throughout the specific duration. The AT detection system may include an output unit that may output the detected AT to a user or a process.
