Abstract
Electrophysiologic data (EPD) obtained during cardiac catheterization (cath) are usually measured after the cath. Drawbacks to this are: (1) the data may not be complete, and (2) the measurement process is time-consuming. A Norland 3001 waveform analyzer was programmed to measure intracardiac EPD on-line rapidly during the cath. It determined heart rate and conduction times through the His-Purkinje system (H-V), AV node (LRA-H), right atrium (HRA-LRA), left atrium (HRA-LA) and right bundle branch (V-RVA) in 17 sec without hand digitization. Data on 49 patients aged 1 month to 68 yrs (median 8 yrs) were obtained. EPD were recorded on paper and measured after the cath in a double blind manner. It is concluded that automated measurement of EPD is feasible and, when extended to measuring sinus node and AV node function, the saving in time will be important.
