Conversational Atrial Tachycardia

Silence Is Golden

“…Speech-induced AT is rare, and only sporadic cases were reported. [2][3][4] However, the underlying mechanism is unclear. In our case, we found that an increase in LAP preceded the episode of AT.…”

“…In fact, similar viewpoints have been revealed by a few previous reports. [2][3][4] Nevertheless, the exact mechanism of speech-induced AT remains to be elucidated in the future.…”

“…1) However, speechinduced AT is extremely rare. [2][3][4] Here, we report a case of speech-induced AT and its relevant electrophysiological characteristics.…”

Social anxiety provoked by speech-induced atrial tachycardia

“…AT and AF have been reported with coughing, speaking, and swallowing 2, 3, 4, 5, 6, 7. One case localized the site of earliest activation to the roof of the left atrium, whereas another noted earliest activation was in the anteroseptum of the left atrium 2, 3. Fan et al 2 postulated that it may be due to an anomalous efferent input from the recurrent laryngeal nerve to the left atrial ganglionic plexuses.…”

Fan et al 2 postulated that it may be due to an anomalous efferent input from the recurrent laryngeal nerve to the left atrial ganglionic plexuses. Omori et al 6 believed the arrhythmogenicity of the vagal nerve stimulation in their case was supported by the effectiveness of atropine and the propensity to increase the arrhythmia with digitalis though direct vagotonic action.…”
