| Popis: | The concept of a mean vector with respect to time for a certain time interval is discussed. A simple method for determining the area vector for electrocardiographic cardiac complexes is presented, and the theoretical and practical advantages of its use are discussed. The ventricular gradient area difference vector is defined and is determined for the dog experiment of Wilson and associates, for two cases of right and two cases of left intermittent bundle branch block and for one case of intermittent anomalous atrioventricular excitation. It is pointed out that in each case this difference vector may be due to alteration of the lead fields or may be an indication of invalidity of Wilson's hypothesis. |
