Data collection
A quick response (QR) code was created to facilitate the process of
recruiting cardiologists in the survey. The QR code was initially
released at the 20th CHRS scientific sessions in
August 2020 and circulated via several social media platforms targeting
cardiologists in the following 4 months. After scanning the QR code,
participants would be guided to the survey website for eligibility
assessment. The questionnaire would launch after the participant
providing informed consent.
