Observational (n=5)
Anatomical and electrophysiological findings support the helical ventricular myocardial band model, identifying a cardiac fulcrum and an activation sequence that explains ventricular torsion and active diastolic suction.
Animal findings bolster helical band model; leaves open human translation for ventricular twist and suction.
This pathway leading from structure to function induced gave rise to the following research studies: 1) Anatomical and histological investigation of the segmental sequence of the structure of the heart muscle.

Trainini Jorge (2021) conducted an observational in Normal QRS complexes (undergoing radiofrequency ablation for arrhythmias) (n=5). Three-dimensional endoepicardial electroanatomic mapping and anatomical dissection was evaluated on Electrical activation sequence and anatomical structure of the myocardium.
