Aims: Our aim was to find a strain-based echocardiographic measurement that could detect a difference in the LV function cardiac mechanics between paced and intrinsic conduction. The study assessed strain-based measurements to identify whether they could differentiate between RV apical and RVOT pacing when comparing paced beats to intrinsic beats. Methods: An observational study was performed on echocardiographic data from twenty-seven subjects (75 ±9.2 years) who received permanent pacemaker systems, then a combined pacemaker check and echocardiogram peri-procedurally. These subjects had normal underlying cardiac structure and function. The group was separated into RVA (n = 12) and RVOT (n = 15) for sub-group comparison. Parameters were a...
