Preexcitation Syndromes
Key Points Terminology: WPW pattern = ECG evidence of pre-excitation without symptoms. WPW syndrome = pattern plus symptomatic tachyarrhythmia (e.g., AVRT, pre-excited AF). Mechanism: An atrioventricular accessory pathway (e.g., Kent;…
Post cardioversion ECG of SVT in patient with palpitations and near syncope
A 29-year-old woman presents to the emergency department with an episode of palpitations and near syncope. She reports several similar episodes in the past that were brief in duration and…
Wide Complex Tachycardias: when administering the wrong medication can cause a “clean kill”
A young patient is brought to the ED complaining of palpitations and mild shortness of breath. The patient does not appear acutely unstable. The following ECG is obtained:
Narrow Complex Tachycardias: the importance of careful ECG interpretation after cardioversion for tachyarrhythmia
A 15-year-old girl presents is brought to the ED complaining of palpitations and near-syncope. She is found to be tachycardic on arrival and the following ECG is obtained:
Wolff-Parkinson-White: a ventricular preexcitation syndrome
A 16-year-old patient presents to the ED complaining of palpitations and lightheadedness. She reports upper body twitching associated with her palpitations and increased levels of stress and anger recently. The…
