How to determine Successful placement of TransVenous Cardiac Pacing
Successful placement = placed into right ventricle
Monitor= left bundle branch block with left axis deviation
This occurs at a depth of at least 20 cm.
Transvenous Cardiac Pacing
Right IJ vein, left subclavian vein
Electrocardiographic guidance if patient has cardiac activity
Attach ECG machine V lead to pacer wire negative electrode
Wire in right atrium: large, biphasic P waves
Successful placement in right ventricle: left bundle branch block with left axis deviation
Good positioning of leads: capture with < 1 mA
Central Cord Syndrome
Most common incomplete spinal cord syndrome
Hyperextension injury
Bilateral motor and sensory deficits
Upper extremity > lower extremity
- hyperflexion injury or laceration of the anterior spinal artery
- loss of motor and sensory function below the level of injury
- preservation of the posterior column (position, touch, vibration)
Anterior cord syndrome
Isolated pubic ramus fractures rx
These injuries are typically managed conservatively with pain control, crutches, appropriate weight-bearing instructions and outpatient orthopedic follow-up.
appropriate to be discharged with weightbearing as tolerated.

Hearing Loss Conductive test
Weber: localizes to affected ear
Rinne: abnormal (BC > AC)
Most commonly caused by otitis media, serous otitis, and cerumen impaction
Hearing Loss Sensorineural tests
Weber: localizes to unaffected ear
Rinne: normal (AC > BC)
Most commonly caused by excessive noise exposure, drugs, and normal aging
What is the recommended treatment of choice of sudden onset sensorineural hearing loss?
Prednisone 1 mg/kg/day (up to 60 mg) for 10–14 days.
