Provides methodological support for noninvasive His-Purkinje recordings; leaves open clinical adoption pending prospective validation.
Noninvasive His-Purkinje system (HPS) recordings can be obtained using high amplification and signal averaging. However, this technique lacks the firm underpinnings necessary for its establishment as a useful clinical tool for the study of the electrical activity of the heart. Previous work has been incomplete resulting in fragmented knowledge of the body surface HPS activity and the nature of the HPS as an electrical source.
