Summary

This study tests a new technology that listens to your voice during short phone calls to detect atrial fibrillation, a common heart rhythm problem. Researchers will enroll 40 adults scheduled for a heart reset procedure (cardioversion) and compare voice recordings with standard heart tests. If successful, this could lead to a simple, low-cost way to monitor heart health remotely without special devices.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adults (≥18 years) with a diagnosis of atrial fibrillation scheduled for elective direct-current cardioversion at the Minneapolis Heart Institute Foundation (Abbott Northwestern Hospital). Eligible patients are identified by research staff via EMR pre-screening of cardioversion/procedure and clinic schedules and by provider referral; written informed consent in English is obtained prior to the procedure. Key exclusions: prior pacemaker; dysphasia or word-finding difficulty; vocal cord dysfunction; atrial flutter as the presenting arrhythmia; planned transesophageal echocardiogram (TEE) with cardioversion. No upper age limit. Single-center, single-cohort; no biospecimens collected.
