We postulated that reducing peak leading edge shock voltage and its rate of rise (waveform rounding) would reduce energy requirements for cardioversion of AF and AFl, and may therefore reduce patient discomfort. Transvenous defibrillating catheters (

Using a unipolar esothoracic pacing system (where current passes from a point source positioned in the distal esophagus to a chest wall pad) and pulse duration of 50 msec, satisfactory 1:1 ventricular capture was obtained in 57 (86%) of 66 patients,

Using a newly developed 64-electrode portable mapping device, QRS and ST-T isointegral maps were compared in 194 control subjects and 101 patients. One hundred ninety-four control subjects (mean age, 48 years; 120 men) with no history of cardiac dise

The conventional clinical procedure in an electrophysiological study (EPS) involves transvenous catheterisation and access to X-ray fluoroscopy. Esothoracic electrophysiology (ETE) is a viable non-invasive alternative for conducting EPS without acces

Conventional electrophysiological study of the heart requires very low energy stimulation pulses but, transvenous catherisation and access to x-ray fluoroscopy, are necessary for this clinical procedure. An interface module was developed in order to
