A small dedicated, computer‐controlled waveform analyzer was used to automatically measure the R‐R cycle length, low right atrium to His, and His to ventricle intervals obtained during electrophysiologic studies on 35 patients. These measurements were compared to intervals handmeasured separately and found to correlate well (0.92, 0.63, and 0.75, respectively). The sources of error, possible pitfalls, and future uses of this technique are discussed.
