IBHRE CCDS study guide
IBHRE CCDS · Work through your exam, one topic at a time.
The Certified Cardiac Device Specialist (CCDS) credential is awarded through IBHRE, the International Board of Heart Rhythm Examiners, based in Washington, DC. IBHRE describes the underlying examination as the Examination for Competency in Cardiac Rhythm Device Therapy for the Allied Professional, and states that the exam was designed to establish a standard knowledge base for those involved in assisting physicians and other health care professionals in the implantation and management of pacemakers and ICDs. That scope statement is the clearest public description of what the credential targets: allied professionals and device representatives who support pacemaker and ICD cases rather than physicians directing them. The CCDS Exam appears in both the Allied Professionals and Physicians sections of IBHRE's site, and each section links its own application, eligibility policy, exam content outline, fees page, and recipients list. Candidates should treat those pages as authoritative rather than relying on secondhand summaries, because eligibility rules and pricing differ by pathway. IBHRE also publishes a Cardiac Rhythm Device Reading List, study tips, an online device course, a mentorship program, and a scholarship program. Topics on this exam: Cardiac rhythm device therapy (pacemakers and ICDs) - implantation and management knowledge base for allied professionals assisting physicians. The IBHRE CCDS study guide has 1 section and about 377 words.
01Cardiac Rhythm Device Therapy: Pacemakers and ICDs
This domain covers indications, programming, and follow-up of pacemakers and ICDs from the allied professional's perspective: recognizing when a device is indicated, interpreting NBG codes and timing cycles, checking lead performance, and troubleshooting malfunctions. Questions often pair a clinical vignette with programmed parameters or a device strip. Pacemaker indications: symptomatic sinus node dysfunction, high-grade AV block, and selected neurally mediated or post-surgical blocks. ICD secondary prevention after VF or hemodynamically unstable VT; primary prevention when LVEF ≤35% with NYHA II–III symptoms on optimal therapy and 1-year expected survival.

- Practice questionsDuring a routine pacemaker follow-up, the programmer printout shows a pacing spike followed by a wide QRS complex with a left bundle branch block morphology.
- FlashcardsNBG pacemaker code. Five-position code: chamber paced, chamber sensed, response to sensing (I/T/D), rate modulation (R), and multisite pacing.
- Cheat sheetPacemaker code (NBG): position 1 chamber paced (A, V, D), position 2 chamber sensed, position 3 response (I inhibited, T triggered, D dual), position 4 rate modulation (R), position 5 multisite (e.g., biventricular).
- Key termsSensing threshold. The smallest intrinsic intracardiac electrogram amplitude that a device reliably detects as a cardiac event at the programmed sensitivity setting, measured in millivolts during testing.
- Study planMap the CCDS exam blueprint by listing each major content area (device indications, implantation technique, programming, follow-up, troubleshooting, electromagnetic interference, radiation safety) and assign a self-rated confidence score from 1 to 5 to each.
- Common mistakesThe exam deliberately varies rate and pacing mode so that memorized default values (for example a fixed 200 ms PVARP or a 250 ms blanking period) are the wrong answer; candidates who rehearsed numbers rather than relationships get trapped by plausible distractors.
