The AVA program combines a thirty-year history with an approach that remains innovative; namely: multivariate statistical analysis on orthogonal ECG leads. Its diagnostic reference base includes only diagnoses independently verified by non-ECG criteria. The diagnostic module assesses probabilities of nine alternative disease categories, based on QRS-T parameters; or four other categories in case of conduction defects. Probabilities of left or right atrial overload are also computed. The program also recognizes wall injury, T-wave abnormalities, electrolyte disturbances, myocardial ischemia, and makes differential diagnoses between strain and digitalis effects. An arrhythmia classification module can generate any of 40 rhythm statements. Signal recognition is based on the spatial velocity function. The program has been translated to a microcomputer version.
AVA程序融合了三十年的历史以及一种仍具创新性的方法，即：对正交心电图导联进行多变量统计分析。其诊断参考基础仅包括经非心电图标准独立验证的诊断。诊断模块根据QRS-T参数评估九种替代疾病类别的概率；对于传导缺陷，则评估其他四种类别。还计算左心房或右心房超负荷的概率。该程序还能识别壁损伤、T波异常、电解质紊乱、心肌缺血，并对劳损和洋地黄效应进行鉴别诊断。心律失常分类模块可以生成40种节律描述中的任何一种。信号识别基于空间速度函数。该程序已被转换成微机版本。
