Effects of High-Intensity, Low-Frequency Periodic rTMS Over the Right Dorsolateral Prefrontal Cortex on Cardiac Autonomic Regulation in Women With Recurrent Pregnancy Loss and Anxiety: A Proof-of-Concept rTMS-ECG Clinical Trial ( NEURO-CARD)
Sponsor: Shenyang Jinghua Hospital
Summary
This proof-of-concept trial investigates whether high-intensity, low-frequency repetitive transcranial magnetic stimulation (rTMS) targeting the right dorsolateral prefrontal cortex (DLPFC) can improve autonomic cardiac regulation in women with recurrent pregnancy loss (RPL) and anxiety. The study explores the lateralised function of the DLPFC in emotional and autonomic control and tests a novel neuromodulation-based strategy to relieve anxiety and sympathetic overactivation.

Interventions
repetitive transcranial magnetic stimulation(rTMS)
The eligible participants will undergo an intensity sweep consisting of six stimulation trains over the right dorsolateral prefrontal cortex (DLPFC), with stimulation intensities ranging from 100% to 150% of the individual resting motor threshold (RMT), increasing in 10% increments. Each train will last 60 seconds, comprising 40 seconds of active rTMS at 1 Hz and a 20-second intertrain interval (ITI). Synchronous electrocardiogram (ECG) data will be continuously recorded throughout the entire procedure.
