Brief Summary: Background Given that an experienced physician is not always available 24 hours a day immediately and always available echocardiography is usually impossible in the emergency department ED and intensive care unit ICU To compensate this limitation the investigators have investigated that offsite expert guided inexperienced practitioner-performed ultrasonography could be effectively performed In this study the investigators aimed to investigate whether the offsite expert can effectively evaluate the visually estimated ejection fraction EF while watching and guiding the echocardiographic procedure of onsite novice examiner using the social network video calling chat

Methods sixty patients presenting to the ICU and requiring echocardiography will be included Sixty novice practitioners without any previous experience of echocardiography will participate Prior to their procedure the onsite expert complete the echocardiography in advance and determine the EF using the modified Simpsons method MSM Reference value Then the novice physicians perform the echocardiography again with the offsite experts guidance via video call They obtain parasternal long and short axis view and EF is visually estimated to the nearest 5 ex 40 45 and etc by the offsite expert while watching the ultrasound video on the smartphone display The subjects requiring immediate management due to severe symptoms were excluded in this study Interobserver variability between the calculated by onsite expert and visually estimated by offsite expert was assessed The agreement of the visual estimated EF obtained by onsite expert and offsite expert via smartphone was evaluated by linear regression and Bland-Altman plots
