A note on ECG changes observed during Pavlovian conditioning in a rhesus monkey following coronary arterial occlusion.

ABSTRACT

Changes in the ECG of a rhesus monkey during a classical aversive conditioning trial conducted 10 minutes after occlusion of the marginal branch of the left circumflex coronary artery have been observed. This appears to reflect an instance where myocardial ischemia following coronary occlusion was exacerbated by presentation of a conditional stimulus.
