Comparison of Spot and Band Impedance Cardiogram Electrodes across Different Tasks
Key result
Spot electrodes and band electrodes showed no differences in determining stroke volume and systolic time interval measures across different tasks, with correlations around 0.8.
Why the study?

Boomsma et al. (1989) reported a cross-sectional. Spot electrodes vs. Band electrodes was evaluated on Systolic time intervals and stroke volume. Spot electrodes and band electrodes showed no differences in determining stroke volume and systolic time interval measures across different tasks, with correlations around 0.8.
