Table 2. Candidate patients for remote CR.

1	Geographically remote patients	Individuals living in rural or underserved areas with limited access to outpatient-CR programs.
2	Patients with mobility limitations	Individuals with physical disabilities or limitations that make traveling to a rehabilitation center difficult.
3	Busy patients	People with demanding work schedules who might find it challenging to attend in-person sessions.
4	Patients who have developed exercise habits	Individuals who already have exercise habits can quickly start the remote CR program.
5	Patients with anxiety or depression	Those experiencing psychological distress following a cardiac event or diagnosis may benefit from a flexible, at-home rehabilitation approach.
6	IT equipment literate patients	Individuals or patients’ families who can use IT devices. Platforms or apps with intuitive interfaces that require minimal technical skills are required.

9	Patients without hearing loss	Individuals with difficulty hearing by phone or bidirectional video.
10	Patients without cognitive impairment	Cognition that can understand the method of the remote CR is required.

12	Patients without CIEDs*	Wearable devices do not guarantee complete safety in patients with CIEDs.
		*However, following the FDA recommendation to keep smartphones and accessories at least 6 inches away from CIEDs, the risk of a clinically significant event is unlikely.

CIED = cardiac implantable electronic devices; CR = cardiac rehabilitation; FDA = Food and Drug Administration; IT = information technology.
