Across 1. Slightly irregular rhythm, three different P waves in six seconds, rate 60-100 4. Absence of all electrical activity 7. Heart rate 40-60, P waves absent or inverted, QRS narrow 8. Atria and ventricles do not communicate and initiate impulses separately 9. Premature beat with an absent or inverted P wave 11. PR interval lengthens each cycle until a QRS complex is dropped 16. Consistent prolonged PR intervals across an entire strip

Down 2. Narrow QRS complex, P waves absent or inverted, rate 60-100 3. Chaotic unorganized lethal rhythm originating n the ventricles 4. This supraventricular rhythm is irregularly irregular 5. Life threatening wide complex tachycardia 6. Three or more ventricular escape beats in a row at a rate of 20-40 9. A premature wide and bizarrely shaped QRS complex 10. Tachycardia originating in the ventricles that twists along the baseline 12. Hallmark sign of this rhythm is saw tooth waves 13. Heart rate increases with pain, fever, hypovolemia 14. Rhythm occurs in well-conditioned athletes 15. Heart rate increases with inspiration and decreaseswith expiration
