- Downsloping TP segment in patients with acute pericarditis
- Potentially present in about 80% of the patients affected with acute pericarditis.
- The sign is often best visualized in lead II and lateral precordial leads.
Spodick sign is statistically associated with pericarditis, but it is seen in 5% of patients with STEMI. Among other findings, ST depression, III > II, and absence of PR depression were the most discriminating. [Witting 2020]
