  2. 52 52 year old Caucas ear old Caucasian ian male male • Recreational runner • Runs 1-2h per week, completed several 5K, 10K runs prior • No cardiac symptoms • No medical history, no medications • Never smoker • Silverstone Half Marathon

  4. Witness itness repor eport • No signs of difficulty prior to collapse. • Fell forward without clear mechanical cause with fascial injury. • First responders. • No convincing pulse and CPR commenced/tolerated. • By the time difibrillator arrived and applied there was rhythm.

  5. Post “ ictal ictal ”/event period • Immediate GCS 3/15 • within 3 mins GCS 7/15 (E2,V1,M4) with head turning to the left, jaw clenching and eye diviation to the left, tonic posture, remained unresponsive • Airway patent • Pupils equal and reactive to light • Within 10mins GCS 14/15 • Disorientation in time • Repeated questioning “ did i finish?” “Where is my family” • Blood glucose normal • Normal intial observations • No focal motor or sensory deficit

  6. Initial Initial tests? tests? • A) Temperature, Sodium, Glucose • B) ECG & Cardiac monitoring • C) None of the above, CT head • D) All of the above

  9. Admitt Admitted ed under car under cardiolog diology • ECGs and 24h rhythm monitoring: No dynamic changes, single episode NSVT, 7 beats • Cardiac troponins – 338ng/L (initial), 334 ng/L (12h) [normal <100ng/L] • Echocardiogram unremarkable • CT Head: right maxillary fracture, soft tissue injury • … What next?

  10. Wha hat ne t next? xt? • A) Discharge, do nothing? • B) ICD? • C) Home with Life vest? • D) Anything else ?

  11. Dia Diagnosis gnosis • Head injury with concussion, secondary brady- asystole and spontaneous recovery • Profound vasovagal syncope with prolonged cerebral hypoperfusion in context of acidosis/dehydration • Cardiac rhythm disturbance, secondary to …

  14. Results esults • 24h tape: – 8x VEs – variable morphologies, occasional AEs, short episodes atrial bigeminy • ETT: – 15min34 Bruce protocol on treadmill, achieved 98% max HR at a workload of 18 METS. Test terminated due to fatigue and lightheadedness. Isolated PVCs with one couplet. No significant ST changes. Marked drop in BP in initial recovery.
