“…21 Our study also showed a significant difference in heart rate between patients with and without SSS at baseline ( Table 2; 64 beats/min, (53-80) vs. 81 beats/min (71-90), P=0.002) and during isoproterenol (109 beats/min (100-124) vs. 128 beats/min (117-140), P=0.002). Therefore, a poor increase in heart rate could be a characteristic of patients with SSS.…”

Background: This study sought to evaluate whether a poor increase in inferior P-wave amplitude during sympathetic stimulation might be a helpful diagnostic tool for sick sinus syndrome (SSS). Methods and Results:Three-dimensional electroanatomic mapping of the right atrium, inferior P-wave amplitude and conventional corrected sinus node recovery time (CSNRT) were compared in 112 consecutive atrial fibrillation (AF) patients with (n=21) and without SSS (n=91). The significant cranial shift of earliest activation site (EAS) (the distance from the superior vena cava to the EAS: 11.1 vs. 5.9 mm, P<0.001) and the increases of inferior P-wave amplitudes during isoproterenol infusion (all P<0.001) were observed in patients without SSS. However, cranial shift of EAS (16.5 vs. 14.2 mm, P=0.375) and P-wave amplitude increases were not observed in those with SSS. Although CSNRT >550 ms showed a sensitivity of 50% and specificity of 84% for diagnosing SSS, poor increases of P-waves amplitude in lead aVF (<0.1 mV) during isoproterenol infusion showed an improved sensitivity of 71% and specificity of 89%. Finally, the combined algorithm using CSNRT >550 ms and poor increase of P-waves amplitude in lead aVF showed more improved diagnostic accuracy (sensitivity 89%, specificity 75%). Conclusions:A combined algorithm using inferior P-wave amplitude showed improved performance for the diagnosis of SSS compared with CSNRT >550 ms alone. (Circ J 2015; 79: 2148 -2156

Sinus node function, including automaticity, conduction, and refractoriness, can be studied in the human electrophysiology laboratory. This review details the current methods used for such studies and discusses their clinical value. Of special emphasis in this article is the role of sinus node electrography in the clinical laboratory. Included also is an update of the data relating the duration of sinus node depolarization as measure on sinus node electrograms to other parameters that assess sinus node function as well as data supporting the direct relationship between the duration of the sinus node depolarization as the severity of sinus node dysfunction.
