摘要：The patterns of contraction and relaxation of the heart before and during leftventricular or biventricular pacing are analyzed and displayed in real time mode to assistphysicians to screen patients for cardiac resynchronization therapy, to set the optimal A-
V or right ventricle to left ventricle interval delay, and to select the site(s) of pacing thatresult in optimal cardiac performance. The system includes an accelerometer sensor; aprogrammable pace maker, a computer data analysis module, and may also include a 2Dand 3D visual graphic display of analytic results, i.e. a Ventricular Contraction Map. Afeedback network provides direction for optimal pacing leads placement. The methodincludes selecting a location to place the leads of a cardiac pacing device, collectingseismocardiographic (SCG) data corresponding to heart motion during paced beats of apatient's heart, determining hemodynamic and electrophysiological parameters based onthe SCG data, repeating the preceding steps for another lead placement location, andselecting a lead placement location that provides the best cardiac performance bycomparing the calculated hemodynamic and electrophysiological parameters for eachdifferent lead placement location.
