Esophageal cardiac pacing effects on arterial pulsations

Electrical stimulation via the esophageal pathway has been demonstrated to be a relatively noninvasive and recommendable approach to cardiac pacing to the termination of arrhythmias. Hemodynamic consequences of this mode of pacing on arterial system function have not been reported. The authors anaesthetized dogs using bipolar catheter electrodes; their results show that transesophageal cardiac pacing alters arterial pulse transmission characteristics only to a limited extent.
