The measurement of the duration of the QRS interval


, : The measurement of the duration of the QRS interval. American Heart Journal 44(1): 80-88

The values of QRS may vary as much as 0.05 sec., due to differences in the duration in different leads, differences in the duration of successive complexes, and difficulties in the detn. of the points indicating the beginning and end of the QRS complex. An attempt is made to set up concrete and objective rules for the measurement of the QRS interval.

Recently, it was demonstrated that the priming stimulation effect (PSE) of intracranial self-stimulation (ICSS) with the runway method can be used as a model system to study the motivation that contributes to specific behaviors. It was postulated...
