A Technique for Reading Gapless Tapes Makes Electrocardiograph Analysis Feasible on the IBM 7090 To study arrhythmias and higher frequency components of the electrocardiogram, long series of patient heart cycles must be examined before valid comparison of different heart beats can be made. A technique is presented for the automatic analysis of long series heart cycles via a digital computer. CACM November, 1964 Maher, A. S. CA641109 JB March 9, 1978 4:03 PM 974 5 974 974 5 974 974 5 974
