Measurement consistency and three-dimensional electromechanical anthropometry
Two pilot studies investigated potential sources of error in static human body surface measurement for conventional anthropometry methods and three-dimensional electromechanical methods under different experimental conditions. In the first pilot study, two anthropometrists measured Humeral breadth, Radiale-Stylion length and Wrist breadth of a cadaveric arm repeatedly in nearly nude and lightly...
متن کاملNonfluoroscopic Endoventricular Electromechanical Three-Dimensional Mapping
Biosense-Webster, a Johnson&Johnson Company) is a recently developed technique that enables the acquisition of on-line information on the electrical and mechanical endoventricular functioning of myocardial tissue. 1 The rationale for this new technique is 2-fold. First, none of the currently available in-cathlab methods can distinguish viable from non-viable myocardium. Accepted techniques, suc...
متن کاملAtrial electromechanical delay in patients undergoing heart transplantation
BACKGROUND We aimed to assess atrial electromechanical delay (AEMD) in patients who had undergone heart transplantation. METHODS A total of 32 patients who underwent biatrial anastomosis heart transplantation (24 men, 8 women; mean age: 42±11 years) and 30 healthy volunteers (20 men, 10 women; mean age: 36±13 years) were included in the study. Atrial electromechanical coupling (PA), intra-AEM...
متن کاملTowards an interactive electromechanical model of the heart.
In this work, we develop an interactive framework for rehearsal of and training in cardiac catheter ablation, and for planning cardiac resynchronization therapy. To this end, an interactive and real-time electrophysiology model of the heart is developed to fit patient-specific data. The proposed interactive framework relies on two main contributions. First, an efficient implementation of cardia...
متن کاملEffect of Electric Potential Distribution on Electromechanical Behavior of a Piezoelectrically Sandwiched Micro-Beam
The paper deals with the mechanical behavior of a micro-beam bonded with two piezoelectric layers. The micro-beam is suspended over a fixed substrate and undergoes the both piezoelectric and electrostatic actuation. The piezoelectric layers are poled through the thickness and equipped with surface electrodes. The equation governing the micro-beam deflection under electrostatic pressure is deriv...
