Time since presentation	Event
0 min	Patient presented to the emergency department reporting several hours of chest pain with initial HR 130 b.p.m. and BP 80/50 mmHg.
10 min	Initial ECG demonstrating ST elevations in the inferior leads (II, III, aVF).
40 min	CT angiogram chest demonstrates no aortic dissection but identifies large pericardial effusion.
1 h 20 min	Coronary angiogram performed; right coronary artery (RCA) with diffuse subtotal occlusion; left anterior descending (LAD) with 95% proximal stenosis; distal abdominal aorta and bilateral common iliac arteries diffusely diseased.
1 h 40 min	Emergent transthoracic echocardiogram performed in catheterization laboratory with large pericardial effusion and echocardiographic findings of tamponade; pericardiocentesis performed with 800 mL of serosanguinous fluid removed.
2 h 30 min	Repeat ECG showed resolution of inferior ST elevations; HR 100 b.p.m. and BP 140/60 mmHg.
17 h	Repeat coronary angiogram showed RCA with 20% distal stenosis, LAD widely patent without stenosis, and aortoiliac arteries without stenosis.
2 days	Pericardial drain clamped without re-accumulation of pericardial effusion on repeat echocardiogram.
3 Days	Pericardial Drain Removed.
