Herein, we report results of a follow-up screening protocol for incident atrial fibrillation/flutter (AF) within a large observational digital health study. Of 59 participants who sent at least 1 EKG, 52 (88.1%) were in sinus rhythm, 3 (5.1%) AF, 2 (3.4%) indeterminate, and 2 (3.4%) sinus bradycardia.

Her Apple Watch suddenly told her that she is in atrial fibrillation. Patients with healthy AV nodes who are not on AV nodal blockers and who are not hyperkalemic should have a rapid ventricular response if they have paroxysmal Atrial fibrillation. I focus my comment on a few additional aspects regarding new AFib.

Written by Pendell Meyers First try to interpret this ECG with no clinical context: The ECG shows an irregularly irregular rhythm, therefore almost certainly atrial fibrillation. After an initially narrow QRS, there is a very large abnormal extra wave at the end of the QRS complex. Is there a long QT? How would you manage this patient?

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). interval, at over 600 msec.

Sinus bradycardia – sinus rhythm below 60 bpm is a sinus bradycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. In healthy individuals occurs during exercising or strong emotions.

Atrial fibrillation is also a predictor of worse outcomes in this case (Alborzi). Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). RBBB in blunt chest trauma seems to be indicative of several RV injury. Sinus Tachycardia ( common in any trauma patient. ).

Note: Due to the limited number of normally conducted beats — it is hard to be sure whether the underlying rhythm is sinus with baseline artefact or atrial fibrillation. Note: The patient while on telemetry had alternating atrial fibrillation, sinus rhythm with 1st degree AV block and also periods of Wenckebach conduction.
