Relationships between Interpersonal Networks and Mental Health in High Reassurance Seekers

The current study sought to examine the relationships between reassurance seeking and mental health from the perspective of “emotionships”. High reassurance seekers repeatedly seek reassurance from significant others. Although previous studies reported that interpersonal rejection by significant others mediated relationships between reassurance seeking and mental health, the mechanisms underlying this relationship remain unclear. Thus, the current study examined the relationships between reassurance seeking and mental health using the framework of “emotionships”, which are the structures of interpersonal networks involved in emotion regulation. The findings of previous studies suggest that high reassurance seekers may have narrow interpersonal networks for emotion regulation, resulting in worsening mental health. The results of a questionnaire survey of 56 students indicated that those who engaged in reassurance seeking tended to have fewer emotional domains and interpersonal networks for interpersonal emotion regulation. In addition, interpersonal networks for emotion regulation were positively correlated with well-being. These findings indicate that maintaining interpersonal networks for interpersonal emotion regulation may be important to prevent the deterioration of mental health for reassurance seekers

993-40 Characteristics of the Atrial Signal-averaged Electrocardiograms in Patients with Sick Sinus Syndrome – the Presence of “Atrial Early Potential”

In sick sinus syndrome (SSS), pathophysiological abnormalities have been shown not only in the sinus node but also in the atrial muscle, especially of the perinodal portion. To investigate whether the electrophysiological abnormalities of atrial muscle in SSS would induce the characteristic P wavepattern, especially in the initial portion of the P wave, we studied 37 patients with SSS and 67 age-comparable control patients. using the P wave-triggered signal-averaged electrocardiography. Sixteen of 37 SSS patients had paroxysmal atrial fibrillation (Paf). Signal-averaged electrocardiograms were recorded with a band-pass filter of 40–300Hz and signals of 200 beats or more were averaged with the P wave-triggering technique. The P wave complexes of the three bipolar leads were combined into a spatial magnitude, and then the root mean square voltage for the initial 30ms (EP30) and the last 20m (LP20) of filtered P wave were measured. The duration (Ad) and root mean square voltage (RMS) of the total filtered P wave were also measured.ResultsSSS with PafSSS without PatControlEP30 (μV)2.55±1.17*2.16±0.98*3.93±1.23LP20 (μV)1.98±0.40#†2.79±1.043.35±1.76Ad (ms)145.8±16.1*†131.2±14.1123.7±11.7RMS (μV)6.20±0.415.82±0.826.20±1.47*p<0.0001#P<0.005p&lt;0.05 vs. Control†p&lt;0.01 vs SSS Without PatThe amplitude of initial portion of filtered P wave was significantly lower and the duration was longer in SSS patients with/without Paf than the controls, while there was no significant difference in the amplitude of the terminal portion between SSS patients without Paf and controls. The criteria of “EP30≤3.0μV and Ad&gt;130m” as defining “atrial early potential” gave a sensitivity of 76%, a specificity of 83% and a predictive accuracy of 81% for detection of patients with SSS. These results indicate that the low amplitude signals in the initial portion of filtered P wave were characteristic of SSS, so that the recognition of atrial early potential might be promising to identify patients with SSS
