The study evaluates the performance of closely separated (6 cm) bipolar leads in differentiating subjects with left ventricular hypertrophy (LVH) from normal subjects. The study population consists of 236 healthy subjects, 116 pure LVH patients) and 189 complex LVH patients. A total of 36 vertical, 30 horizontal and 66 diagonal bipolar leads located on the anterior thorax were analyzed. The findings...
The present study applies modeling methods to study the simulated ECG of a subQ monitor with bipolar lead. The objective of the study was to analyze how different locations of ectopic activation affect the ECG obtained with horizontal and vertical electrode orientation. The ectopic activation was set to originate from 6 different locations and conduct through both ventricles. We had implants in 63...
Modeling offers effective means of studying the effects of implant dimensions on the measured electrocardiograph (ECG) prior to any in vivo tests, and thus provides the designer with valuable information. Finite difference (FDM) and lead field approaches combined with cardiac activation models offer straightforward and effective methods for analyzing different ECG measurement configurations. In the...
Lead design is a critical factor for detecting and redetecting lethal arrhythmias in electrograms (EGM) from Implantable Cardioverter Defibrillators (ICD). The estimation of the scope of a lead can help to elucidate the anatomical origin of recorded EGM and explain signal features. In this paper, we compare quantitatively the scope of true and integrated bipolar sensing leads by combining bioelectric...
New heart monitoring devices such as implantable ECG recorders may provide effective ways to monitor specifically certain heart region, e.g. ischemic region. Previously we have developed and presented the region of interest sensitivity ratio (ROISR) parameter to describe how specific a measurement is to the activation arisen the ROI compared to other source regions. Present study demonstrates the...
