An conventional Holter monitors, a one- or two-channel recording is made for a period of time, in the range of 10 to 26 hours, of the heart waveforms of a patient performing normal daily activity. The detection of abnormalities is obtained by scanning the tape at very high speed using visual and audio aids. The process requires one to two hours and results in strip chart tracings of significant waveforms for cardiologist review. The small number of tapes an operator can analyze in a day due to this excessive time and resulting fatigue contribute to the high cost of this procedure which has become an important tool in early diagnosis of heart disease.
