Atrial Fibrillation Bradycardia Dysrhythmia

OCTOBER 24, 2024
This ECG shows sinus bradycardia with massively long QT (or QU?) Especially when present in the setting of bradycardia and syncopal episodes, this is very worrisome for high risk of lethal dysrhythmias including polymorphic ventricular fibrillation (termed Torsades when in the setting of long QT).

Atrial fibrillation is also a predictor of worse outcomes in this case (Alborzi). See these publications for more information Overall, management for cardiac contusion is mostly supportive unless surgical complications develop, involving appropriate treatment of dysrhythmias and hemodynamic instability.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. There is atrial fibrillation. Could the dysrhythmias have been prevented?

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
