P445 HEART RATE VARIABILITY AND HYPNOTIC COMMUNICATION

Abstract Background Heart rate variability (HRV) can be influenced by the autonomic nervous system and several studies showed that hypnotic communication could modulate system. In particular, HRV is related to activity of vagus nerve an increment vagal activation has been associated improvement in prognosis. It is, however, unclear whether influence HRV. Aim study The aim present evaluate impact on Methods Seven volunteer were included (5 M/2F) from June August 2022. Each one underwent 1 hour ECG registration normal condition, 30 minutes during depth after communication. was performed via neutral hypnosis; parameter considered for evaluation sNN50 (dec), SDNN(ms), SDNNi, RMS SD triangular index, analyzed throughout dedicated software Pathfinder SL (V 1.9.3.13414, spacelabs healthcare Ltd 2021, WA, USA). variation each evaluated Student T test. Results There no statistically significant among post a index (Fig.1) heart (Fig. 2). Conclusion Hypnotic increase HRV, assessed as (the suggested European society cardiology (ESC) American college (ACC) measure HRV). absence between condition explained deep modification respiratory pattern induced communication; those mask due communication, unmasked post–hypnotic period which return value. Further are needed understand show prognosis cardiopathic patients, it demonstrated muscular training.
