Why the study?
Does intense heat exposure (sauna) alter electrocardiogram and plasma catecholamine levels differently than exercise in subjects with and without coronary heart disease?
Population
35 subjects (17 with apparently normal hearts and 18 with coronary heart disease)
Comparison
Short period of exposure to intense heat of a… vs Exercise

Sauna may warrant caution in CHD patients; leaves open whether unbalanced adrenaline response increases arrhythmic risk versus exercise.
Does intense heat exposure (sauna) alter electrocardiogram and plasma catecholamine levels differently than exercise in subjects with and without coronary heart disease?
Intense heat exposure induces an unbalanced adrenaline increase associated with ischaemic-like ECG changes and ectopic beats, contrasting with the balanced catecholamine response and fewer ECG changes seen during exercise.
Taggart et al. (1972) studied this question.
