Why the study?

Do 32-lead sets improve the estimation of total body surface potential distributions compared to 30-lead precordial or conventional 9-lead systems?

Comparison

Implication

Optimally placed 32-lead arrays may refine body surface mapping; leaves open clinical utility versus standard leads.

Structured PICO

Do 32-lead sets improve the estimation of total body surface potential distributions compared to 30-lead precordial or conventional 9-lead systems?

I
Intervention
Two practical, limited lead sets of 32 leads each
C
Comparator
30 precordial leads and 9 leads simulating conventional 12-lead examinations
O
Outcome
Ability to estimate 192 lead measured maps (average rms voltage error and average correlation coefficient)surrogate

Properly located 20-35 electrode arrays provide significantly better total body surface potential estimation than conventional or 30-lead precordial arrays.
