PROPHECY EKG 2026 VERIFIED QUESTIONS
ANSWERS BEST A+ SOLUTION
◉ prolonged QT interval. Answer: more than 1/2 of R-R interval
caused by: hypocalcemia, TCAs (amytriptilline, celexa, lexapro),
olanzaprine, antihistamines, haldol, digoxin
can lead to: Torsades de Pointes --> sudden cardiac death
s/s: high BP, syncope, anxiety, diaphoresis
◉ short ST. Answer: indicates hypercalcemia
◉ afib w/ RVR. Answer: >100bpm aka "uncontrolled atrial fibrillation"
◉ afib w/ controlled ventricular response. Answer: <100bpm
◉ vtach. Answer: >4PVCs
--> put on pads!
◉ SVT. Answer: >150bpm
constant PR interval, no distinguishable P- or T-waves
, tx w/ cardioversion for unstable SVT, try vagal maneuvers or adenosine
for stable SVT
◉ idioventricular rhythm. Answer: 20-40bpm
◉ multifocal. Answer: multiple different looking PVCs
◉ PVCs. Answer: outlier QRS
◉ PACs. Answer: outlier P-wave (ECTOPY) with compensatory pause
◉ WAP. Answer: >3 different looking P-waves
◉ junctional rhythm. Answer: 40-60bpm, distorted P-wave w/ narrow
QRS
regular rate w/ inverted or hidden P-wave
aka "retrograde conduction" or "junctional escape" d/t contracting
backwards
caused by: digoxin, beta blockers, hyperkalemia, 3rd heart block or sinus
arrest
