Regularly Irregular Rhythms: Sorting Mobitz from PACs and Other Causes
A 52-year-old woman presents to the emergency department with weakness. The following ECG is obtained:
Grouped Beats: A Subtle AV Block Pitfall
An elderly patient is brought to the emergency department with acute stroke symptoms and the following routine 12-lead ECG is obtained during the patient’s stroke evaluation:
Clumped or Grouped Beats DDx
Key Points Clumped or grouped beats can cause irregular rhythms, often leading to misdiagnosis as atrial fibrillation. Misdiagnosing atrial fibrillation may lead to inappropriate rate/rhythm control or unnecessary anticoagulation in…
