Method of analyzing biological signals representative of voltage changes, including obtaining an analog biological signal representative of voltage changes, using digital processing software to digitize the biological signal, displaying the processed biological signal in analog form on a display in a time compressed format, wherein an amount of compression for the time compressed formal is selected such that graphical patterns are made perceivable on the display that signify an abnormality in the biological signal, and visually analyzing the biological signal on the display to characterize the abnormality.

600/300000

Method of analyzing biological signals, including obtaining a magnetic recording media having an analog biological signal recorded thereon, using digital processing software to digitize the biological signal, displaying the digitized biological signal in analog form on a display, and visually analyzing the biological signal on the display. The biological signal may be an electrocardiogram. Preferably, independent channel enhancement of the dynamic range of the analog biological signal is performed prior to digitizing The displayed biological signal is preferably presented in time compressed form. Digitizing is performed by sampling the biological signal at at least approximately 44,100 Hz per second per channel and quantization of at least 16-bits per sample per channel. The digital processing software is preferably digital audio processing software.

A pharmaceutical composition for the treatment of cardiac arrhythmia comprising an effective amount of propafenone in combination with a subtherapeutic amount of quinidine, such that the quinidine potentiates the elimination half-life of the propafenone. The invention also comprises a method for treating patients with cardiac arrhythmia by means of administering said pharmaceutical composition.
