This editorial refers to "Changes in autonomic nervous system activity: spontaneous versus balloon-induced myocardial ischaemia"
by O. Manfrini et al. on page 1502
In this issue of the Journal Manfrini et al.,1 demonstrate that radically different autonomic profiles accompany episodes of spontaneous myocardial ischaemia compared to myocardial ischaemia in the same patient. Practicing cardiologists have known for decades that the location of myocardial ischaemia determines the pattern of autonomic response. For example, acute transmural anterior wall myocardial infarction is often accompanied by sympathetic activation, sinus tachycardia, and relative hypertension, while inferior wall infarction is accompanied by sinus bradycardia and hypotension. Given that heart rate variability is assumed to shed insight into the balance between vagal and sympathetic tone,2 this led to
