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. Baseline bradycardia in endurance athletes limits the use of ß-blockers.

The rhythm now is atrial fibrillation. The arrhythmia spontaneously converted before defibrillation was achieved. As per Dr. Nossen — today's initial ECG ( LEFT tracing in Figure-2 ) shows sinus bradycardia with QRS widening due to bifascicular block ( RBBB/LAHB ). In the initial ECG (ECG# 1) aVR had ST elevation.

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. After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation.

The patient was put on Extracorporeal Life Support in the ED 3 hours after initial resuscitation, the core temp was 30° C and the patient was defibrillated with a single attempt. On arrival, CPR was continued and core temperature was measured at 18° C (64.4° A 12-lead ECG was recorded: There is sinus rhythm with RBBB and right axis deviation.

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. After pacing, there was no recurrence of Torsades.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI. 2:34 PM, following right heart catheterization She then went into atrial fibrillation with complete heart block and junctional escape rhythm prompting placement of transvenous pacemaker.
