Why the study?

Does experimentally induced anxiety via shock warning signals alter human heart rate?

The study aims to explore the dual effects of anxiety on heart rate, specifically both acceleration and deceleration during induced anxiety.
Subjects were presented with visual numbers followed by a shock to induce anxiety.
Heart rate and respiratory activity were measured during the presentation of stimuli.
Cardiac effects were observed in the same subjects under varying experimental conditions.
Initially, heart rate increased sharply when subjects first saw the visual numbers.
After the first shock, the increased heart rate diminished and was later replaced by a decrease in heart rate.
Findings indicate that both acceleration and deceleration of heart rate occur in response to anxiety stimuli.

Does experimentally induced anxiety via shock warning signals alter human heart rate?

Population

Human subjects (Ss)

Intervention

Experimental induction of anxiety via warning signals (visually-presented numbers) followed by a shock

Outcome

Heart rate and respiratory activitysurrogate

Anticipatory anxiety induces a biphasic heart rate response, with initial acceleration transitioning to deceleration after initial shock exposure.

Should not yet change clinical anxiety assessment; leaves open extension to cardiovascular risk populations.

Deane et al. (1958) studied this question.
