Hospital Wearable Defibrillator Inpatient Study

A multi-center prospective study of hospitalized patients whom a physician deems at risk of sudden cardiac arrest during the hospitalization period, wearing the HWD1000 hospital wearable defibrillator in order to evaluate caregiver and patient interactions with the device. In addition, ECG signal quality will be reviewed to confirm the HWD1000 safety profile.

Inclusion criteria

Patients whom a physician deems at risk of sudden cardiac arrest during the hospitalization period (patients will be monitored using the hospital's telemetry system). Specific inclusion criteria are:

• Hospitalized patients having continuous independent ECG monitoring.
• Patients at risk of sudden cardiac arrest during the hospitalization period as determined by the investigating physician.
• Patient ≥18 years of age (over the legal age of providing consent).

Exclusion criteria

• Patients with an active implantable cardioverter-defibrillator.
• Patients with an active unipolar pacemaker.
• Patients with physical or mental conditions preventing them from interacting with or wearing the device as determined by the investigating physician.
• Patients having an advanced directive prohibiting resuscitation.
