Key result
Anterior myocardial ischemia during variant angina was associated with significantly increased heart rate and ectopic arrhythmias, whereas inferior ischemia led to decreased heart rate and AV block.
Why the study?
How do heart rate and arrhythmia incidence differ between anterior and inferior myocardial ischaemia during episodes of Prinzmetal's angina?
Observational
How do heart rate and arrhythmia incidence differ between anterior and inferior myocardial ischaemia during episodes of Prinzmetal's angina?
Anterior and inferior acute myocardial ischaemia in Prinzmetal's angina elicit different autonomic nervous system responses, leading to distinct heart rate changes and arrhythmia profiles.

May warrant site-specific arrhythmia monitoring in variant angina; hypothesis-generating for autonomic mechanisms and risk stratification.
Pérez-Gómez et al. (1979) conducted an observational in Prinzmetal's angina. Anterior myocardial ischaemia vs. Inferior myocardial ischaemia was evaluated on Heart rate changes and incidence of arrhythmias during variant angina. Anterior myocardial ischemia during variant angina was associated with significantly increased heart rate and ectopic arrhythmias, whereas inferior ischemia led to decreased heart rate and AV block.
