title: Computerized electrocardiogram interpretations: are they useful for the family physician?
abstract: Computerized electrocardiogram (ECG) interpretation programs have become increasingly popular in this country, especially in hospital settings. In general, they reliably calculate heart rate, intervals, and mean QRS axis. When the computer interprets an ECG as normal, it is usually correct. The second opinion provided by computerized readings further benefits the primary care physician by suggesting findings not initially considered, and by forcing careful scrutiny of the original interpretation. Speed of interpretation may be greatly increased, particularly for the more experienced electrocardiographer who has a high volume of tracings to interpret. Each computer statement, however, must be carefully overread by the physician, for failure to do so may result in overlooking significant electrocardiographic findings. It is important that the family physician appreciate the strengths and weaknesses of computerized ECG interpretations so that he or she derives the greatest benefit from this diagnostic tool.
