Arrhythmia
Results:
Ectopic Atrial Rhythm
Key Points Definition: Ectopic atrial rhythms occur when atrial depolarization originates from a site other than the sinoatrial (SA) node, producing P waves with abnormal morphology and axis on ECG….
Brugada Syndrome (BrS)
Key Points: Life-Threatening Sodium Channelopathy: Predisposes to ventricular arrhythmias (VF/VT) and sudden cardiac death (SCD), often in otherwise “healthy” hearts. When to Suspect BrS: Patients with syncope, unexplained “seizures,” ventricular…
Wide Complex Tachycardias: does response to Valsalva maneuvers or adenosine rule out ventricular tachycardia?
A 54-year-old man with no significant PMHx presents to the ED with palpitations. He is hemodynamically stable with a normal blood pressure. The following ECG is obtained prior to the…
