Ultrasound-guided pacemaker implantation at the bedside: A lifesaving technique for cardiac emergencies.

Objective: To investigate the safety and effectiveness of implanting temporary pacemakers using ultrasound-guidance at the bedside for rescuing patients in case of cardiac emergencies.

Methods: We enrolled 194 patients with cardiac emergencies requiring temporary pacemakers in this study, and randomly assigned them to either a bedside ultrasound-guided installation group or an electrocardiogram-guided installation group. There were 105 cases in the bedside ultrasound-guided installation group, aged approximately 66.

Doppler ultrasonographic and clinical features of middle aortic syndrome.

Objectives: To discuss Doppler ultrasonographic and clinical features of middle aortic syndrome (MAS).

Materials And Methods: Doppler ultrasonographic images and clinical dates of 11 patients with MAS confirmed by angiography were retrospectively analyzed from January 2004 to September 2016.

Results: The median age of 11 patients was 10 years (1-39 years).
