Look inside
Sample pages from the book
Every rhythm gets a full page: the strip, what to look for, the pearl that makes it stick, and exactly what you do next.
Atrial Fibrillation
Variable (often 100–160)- •No discernible P waves
- •Irregularly irregular R–R
- •Fibrillatory baseline
- •Narrow QRS
New-onset post-op a-fib is common after thoracic/cardiac cases. Loses atrial kick — BP can tank.
What you do: Rate control (dilt/metoprolol), assess stability. Unstable → synchronized cardioversion.
Second-Degree AV Block, Type I (Wenckebach)
Usually slow- •PR gets longer, longer, longer… drop
- •Grouped beating
- •Irregular
- •Narrow QRS
Longer, longer, longer, drop — then you have a Wenckebach.
What you do: Usually benign. Atropine if symptomatic; hold AV-nodal blockers.
Ventricular Tachycardia
100–250 bpm- •Wide bizarre QRS
- •Regular
- •No P waves
- •Often monomorphic
Wide + fast = V-tach until proven otherwise. Check a pulse first.
What you do: Pulseless → defibrillate. Pulse + unstable → sync cardioversion. Stable → amiodarone 150 mg over 10 min.
That's 4 of them. The book has the rest.
