Introduction.
Purkinje system and false tendons (FTs) are related to ventricular arrhythmia, but the association between Purkinje fibers and FTs is not clear.
This study investigated the associations of anatomical and electrophysiological characteristics between Purkinje fibers and FTs.
Methods and Results.
We optimized the protocol of Lugol’s iodine solution staining of Purkinje fibers to study the anatomical structure and originated a novel electrophysiological mapping method, named the direct visual mapping (DVM) method, to study the electrophysiological characteristics.
By using the above-mentioned innovations in 12 dogs, we found the following.
(1) There was no Purkinje fiber found 0.5 cm–1.0 cm below the valve annulus or on the leaflets or chordae tendineae of the mitral valve or adjacent to the top 1/3 of the papillary muscle.
(2) Purkinje fibers existed in all FTs, including smaller and tiny FTs.
(3) The Purkinje fibers contained in the FTs extended from the proximal to the distal end, and their electrophysiological characteristics were similar to the fibers on the endocardium, including anterograde, retrograde, and decremental conduction and automaticity.
Conclusions.
Purkinje fibers are commonly found in FTs.
The electrophysiological characteristics of the Purkinje fibers contained in FTs are similar to the fibers on the endocardium.
FTs might have an anatomical and electrophysiological basis for ventricular arrhythmia.
