Direct Arterial Pressure, Heart Rate and Electrocardiogram During Human Coitus
Why the study?
What are the physiological changes in direct arterial pressure, heart rate, and electrocardiogram during human coitus?
Population
72 human subjects monitored over a 24-hour period, of which 7 normotensive subjects had coitus at home.
Comparison
Coitus (observational exposure) vs Precoital baseline values
Design
Cohort
Follow-up
24 hours

Implication
Coitus elicits marked transient hemodynamic stress; extends direct measurement data but leaves open implications for event risk in cardiac patients.
Structured PICO
What are the physiological changes in direct arterial pressure, heart rate, and electrocardiogram during human coitus?
P
Population
72 human subjects monitored over a 24-hour period, of which 7 normotensive subjects (6 males, 1 female) had coitus at home.
I
Intervention
Coitus (observational exposure)
C
Comparator
Precoital baseline values
O
Outcome
Changes in direct arterial blood pressure (systolic and diastolic), heart rate, and electrocardiogramsurrogate
Coitus induces significant, transient increases in systolic and diastolic blood pressure and heart rate, which peak at orgasm and rapidly return to baseline.
