How the 2025 AHA Guidelines Affect the NREMT Paramedic Exam

What the National Registry announced on October 27, 2025

The American Heart Association published its 2025 Guidelines for CPR and Emergency Cardiovascular Care in Circulation on October 22, 2025, as twelve parts plus algorithms. Five days later, the National Registry explained how its certification examinations, including the National Registry Paramedic Certification Examination, would follow. The announcement has two tracks:

• Live items. The National Registry is reviewing the 2025 guidelines against every operational (live) question. Any question found inconsistent with the new guidelines will be removed, and the review happens over time under National Registry policy.
• New items. Questions written to the 2025 guidelines go through subject-matter-expert review, pilot testing as unscored items, and accreditation compliance reviews. The National Registry says these newly aligned questions are "expected to become operational within 12–15 months."

That is the whole timeline it published. The announcement gives no exact date and names no specific topics.

Our arithmetic, not a National Registry date

Counting 12 to 15 months from October 27, 2025 lands between late October 2026 and late January 2027. That window is Passy's calculation, not a date the National Registry has announced, and "within" allows for some items arriving sooner. Before your test date, check the National Registry's News page for anything newer.

Two other official pages point the same way. The Paramedic handbook tells candidates to review the current AHA guidelines and says the National Registry does not recommend any particular preparation materials. The Paramedic pathway page, as checked on October 18, 2026, lists both the 2020 and the 2025 AHA guidelines among its resources.

2020 or 2025: which edition to study

Learn the 2025 recommendations. The handbook points to the current guidelines, conflicting live items are being taken out, and new items are being written to 2025. A course built on 2020-era materials still covers most of what you need; the tables below show where to update it, and your instructor can tell you which changes the program has already adopted.

These changes reach every National Registry level, but this page reads them through the Paramedic test plan, where Cardiology & Resuscitation is 10–14% of the exam and Clinical Judgment 34–38%. The EMT exam uses a different blueprint. Nothing here replaces your local protocols or your medical director; they decide patient care.

2025 rows to relearn for adult resuscitation

Each row keeps the setting and the class of recommendation (COR) and level of evidence (LOE) as the AHA prints them. Rows 3 to 11 appear in the AHA executive summary's list of significant new and updated recommendations. Rows 1 and 2 come from the Part 9 adult advanced life support tables; they are here because they shape the first minutes of an adult arrest.

Epinephrine timing (row 2) is easy to answer from habit. In the 2025 wording, the rhythm sets the moment: as soon as feasible when it is nonshockable, after the first defibrillation attempts fail when it is shockable. Neither timing row mentions an advanced airway, and row 1 puts the IV ahead of the IO. The free mixed set includes an adult arrest item with a nonshockable rhythm, so once the rows are clear, answer the nonshockable-rhythm epinephrine timing item in a mixed NREMT Paramedic set →.

Row 4 separates two energy recommendations: at least 200 J for atrial fibrillation and 200 J for atrial flutter, using a suitable biphasic device. Both allow escalation after failure; follow the device instructions and protocol.

Row 3 changes the type of shock. For unstable organized tachycardias, the adult guideline uses synchronized cardioversion, but sustained polymorphic VT now goes straight to defibrillation. The free set has a Clinical Judgment item built on that choice: try the sustained polymorphic VT shock decision in the free NREMT Paramedic set →.

The ECG rhythm guide maps the other tachycardia decisions, and the cardiac arrest guide puts rows 1, 2, 7, 10 and 11 in sequence.

2025 rows for children, newborns, pregnancy, and special circumstances

Every topic below appears in the same executive summary list. The hyperthermia classes come from the Part 10 table for adults.

The OB/GYN and newborn guide works through the pregnancy and newborn rows, the pediatrics guide covers the infant and child rows, and the airway guide covers both choking sequences.

How to study the NREMT Paramedic exam during the guideline transition

1. Default to 2025. Where your textbook or notes disagree with a row above, write the 2025 version next to it and learn that one.
2. Learn each row with its setting. The condition column is what separates a correct option from a plausible one: adult or child, shockable or not, pulse present or absent, unstable or stable.
3. Learn decisions, not edition trivia. The National Registry has not said it will ask what changed between editions, so learn each row as an action in a scenario.
4. Check the date on every practice source. Flashcards and question banks written before October 2025 may teach replaced details, such as stepped-up energy for atrial fibrillation or 2-finger infant compressions.
5. Recheck before test day. The National Registry News page is where an update to this timeline would appear.

According to the test plan, every exam item is referenced to industry-standard source materials. Patient care follows your protocols and your medical director, not this page.
