Absent P waves with wide QRS complex indicates serum potassium of: (A) 5.4 meq/L, (B) 6.5 meq/L, (C) More than 8 meq/L, (D) More than 1O meq/L
Answer is C. Hyperkalemia Couesy of Dr. Michael McCrea a. Tall hyperacute T wave (earliest ECG finding) b. Prolonged PR interval c. Flattened or absent P wave d. Wide QRS complex that eventually blends with the T wave to assume a "sine wave" appearance e. Hea blocks f.
