High grade AV block
Results:
Second-Degree AV Block, High-Grade
(Advanced AV Block)
Key Points Definition: A severe form of second-degree AV block—most often Mobitz II—characterized by multiple consecutive non-conducted P waves (e.g., 3:1 or 4:1 conduction). PR Intervals: Constant before conducted beats,…
Bradyarrhythmias: the nuances of complete heart blocks
A 50-year-old man presents to the emergency department with generalized weakness and lightheadedness. He is noted to be bradycardic, and the following ECG is obtained:
Bradyarrhythmias: rash, a history of tick bite, and slow regular rhythms
A 61-year-old man presents to the emergency department with generalized weakness and dyspnea. He reports a recent tick bite and associated circular rash with target-like appearance to the arm. He…
