In order to reduce pacing current threshold in transesophageal stimulation, a novel multi- channel transesophageal pacemaker and multichannel esophageal lead has been developed. Three different approaches to reduce pacing current thres hold were clinically studied. Precise positioning of the pacing dipole allowed reduction of pacing current threshold on average by 20% over the standard bipolar transesophageal method in approximately 50% of patients. Use of a chest electrode lowered pacing…

Measuring heart rate with mobile devices for personal health monitoring
The specialized device with chest strap shows the most accurate heart rate, highly correlated with measurements obtained with a blood pressure monitor that is approved for medical purposes.


Transesophageal atrial pacing: importance of the atrial-esophageal relationship.
The data demonstrated that the threshold for transesophageal atrial pacing was poorly related to the patient's age or size, and suggest that the distance between left atrial posterior wall and the esophagus is small and remains constant despite obvious changes in somatic and linear growth.
Evaluation of transesophageal atrial pacing in the prone and lateral positions.
Transesophageal atrial pacing can be used safely and effectively in patients positioned P, RLD, and LLD and emphasis is given to using the lowest DOIs and smallest currents to reduce the chance of transesophagal ventricular pacing.
The optimal oesophageal pacing technique--the importance of body position, interelectrode spacing, electrode surface area, pacing waveform and intra-oesophageal local anaesthesia.
The optimal pacing technique for TAS remains to be defined and the TAS-induced pain is probably not generated from the oesophageal mucous membrane.
Transesophageal pacemaker therapy in atrial flutter after procainamide pretreatment.
Transesophageal atrial stimulation was applied in 56 patients to terminate atrial flutter and procainamide is more efficacious than digoxin (P < 0.05) in facilitating cardioversion by transesophagal stimulation.
Transesophageal atrial pacing in the management of re-entry supraventricular tachyarrhythmias occurring during general anesthesia.
TAP can be considered as a valid therapeutic device for the management of re-entry SVTs occurred during general anaesthesia, resulting it effective, safe and easy-practicable.
Termination of atrial reentrant tachycardias by using transesophageal atrial pacing.
Transesophageal atrial pacing is recommended as a first step of acute management of atrial flutter and other forms of ART in neonates, infants, and children because it is a minimal invasive procedure with high success rates.
Noninvasive Classification of Ventricular Preexcitation with Unshielded Magnetocardiography and Transesophageal Atrial Pacing and Follow‐Up
This study compared the accuracy of VPx localization with Contactless magnetocardiography with MCG with ECG algorithms, and examined the increment in diagnostic accuracy achievable with TEP.
