Pericardial
Results:
Pericardial Tamponade
Key Points Beyond Electrical Alternans: Although classically linked to tamponade, electrical alternans is present in fewer than 30% of confirmed cases. It’s abscence should never rule out tamponade. Low Voltage…
Low Voltage QRS: DDx
Key Points: Definition: Low voltage QRS complexes reflect decreased myocardial electrical amplitude on ECG. Sensitive Definition (Preferred): Limb leads (I + II + III) sum < 15 mm OR precordial…
Electrical Alternans
Key Points Classically associated with pericardial tamponade but seen in fewer than 30% of confirmed cases. Combination of low-voltage QRS + sinus tachycardia strongly suggests pericardial effusion/tamponade. Always perform rapid…
Pericardial Effusion
Key Point Always consider pericardial effusion in any patient with new low-voltage QRS complexes combined with sinus tachycardia. Prompt bedside ultrasound (POCUS) prevents diagnostic delays and potentially catastrophic outcomes. Classic…
Acute Pericarditis
Key Points Diagnostic Challenge: Acute pericarditis symptoms and ECG findings can closely resemble STEMI/ACS, leading to frequent diagnostic uncertainty in acute care. Critical Importance: Rapid and accurate differentiation from STEMI…
Acute Pericarditis vs STEMI: DDx
Key Points Acute Pericarditis: A challenging diagnosis with symptoms and ECG findings that may mimic STEMI. STEMI: A more life-threatening and time-sensitive condition. Differentiation from pericarditis is crucial to avoid…
