Tachyarrhythmia
Results:
Sinus Tachycardia
Key Points Definition: Sinus tachycardia is a regular rhythm originating from the sinoatrial (SA) node, defined by a heart rate >100 bpm in adults or above age-adjusted norms in children….
Atrial Tachycardia
Key Points: Definition: Atrial tachycardia is a supraventricular arrhythmia characterized by rapid atrial depolarizations from one or more ectopic foci outside the SA node. Atrial Rate: > 100 bpm, typically…
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…
