Wide QRS
Results:
Wide QRS Bradyarrhythmia DDx
Key Points Infranodal Block: Wide QRS bradycardias often indicate an infranodal block, typically involving the His-Purkinje system. These rhythms are more likely to be unstable and may necessitate urgent pacemaker…
Differential Diagnoses: must know causes of right axis deviation and wide QRS complexes
A 30-year-old man is pulled over by police for speeding. He begins feeling nauseous and has multiple episodes of vomiting. During transport to the emergency department by EMS he is…
Differential Diagnoses: important considerations in patients with new onset seizures or altered mental status, must know diagnoses in the emergency department
A 40-year-old man is brought into the ED after being found in the street and noted to have intermittent seizures. He is tachycardic, hypertensive, and febrile. The following ECG was…
Differential Diagnoses: wide QRS, right axis deviation, tall R wave in V1
HPI: A 76-year-old woman presents to the ED with dyspnea and a syncopal episode. History is limited because the patient is listless and confused. The following ECG was obtained: Case…
Literature Review: Wolff-Parkinson-White syndrome with atrial fibrillation
A 50-year-old man is referred from clinic to the ED for chest tightness for the past 3 hours and a presumed new left bundle branch block. He is found to…
STAT ECG Diagnoses: must know ECG differentials in the evaluation of patients with altered mental status
A young woman presents to the ED unconscious with a GCS of 4. The following ECG was obtained during the initial evaluation:
ECG Basics & Fundamentals: a 5 step approach to ECG interpretation and how to think of differential diagnoses
HPI: A 70-year-old man presents with generalized malaise. He has a history of ESRD and has missed dialysis this week. The following ECG is obtained: Case ECG Before watching…
ECG Basics & Fundamentals: a systemactic approach to ECG interpretation
HPI: A 78-year-old male presents to the ED complaining of generalized weakness. Case ECG
Differential Diagnoses: the biggest reason we miss a diagnosis is that we make a diagnosis, and then stop looking
HPI: An unresponsive 45-year-old male is brought in to your ED by ambulance. His wife found him unconscious at home and called 911. History is otherwise limited. Case ECG
