The RCIS (Registered Cardiovascular Invasive Specialist) credential is awarded by Cardiovascular Credentialing International (CCI) and is the primary certification for cardiovascular technologists who work in cardiac catheterization laboratories. If you are preparing for the CCI RCIS exam, a free RCIS practice test PDF is one of the most practical tools you can add to your study plan. Printing and working through realistic questions lets you assess your readiness across all five exam content areas before you sit for the real test.
This page covers everything you need to know about the RCIS exam structure, the clinical knowledge it tests, and the study strategies that help candidates perform their best. Use the download below and the detailed content breakdowns to build a targeted preparation plan.
The RCIS exam is administered by CCI and consists of approximately 200 questions completed in 3.5 hours. The exam tests knowledge across five domains: patient care and safety, cardiac anatomy and physiology, catheterization procedures, pharmacology, and equipment operation and radiation safety. Candidates must achieve a passing score of approximately 75% to earn the credential.
Eligibility requires a minimum of two years of full-time experience in a cardiac catheterization laboratory, though specific educational pathways may reduce this requirement. The RCIS credential is recognized throughout the United States and is often required or preferred by hospitals and cardiovascular centers hiring for cath lab positions.
A thorough understanding of cardiac anatomy is foundational for every topic on the RCIS exam. You must know the four chambers of the heart, the function of all four valves (mitral, tricuspid, aortic, and pulmonic), the coronary artery anatomy including the left main, left anterior descending (LAD), left circumflex (LCX), and right coronary artery (RCA) and their branches, and the conduction system from the sinoatrial (SA) node through the atrioventricular (AV) node and bundle branches to the Purkinje fibers.
The RCIS exam places significant emphasis on hemodynamic concepts. Candidates must interpret intracardiac pressures, calculate cardiac output (CO) and cardiac index (CI), understand the Fick principle and thermodilution methods for measuring CO, and recognize normal versus abnormal pressure waveforms from different chamber locations. Valvular gradients — the pressure difference across a stenotic valve — are calculated from simultaneous pressure measurements and are directly tested on the exam.
Rhythm recognition is a core cath lab competency. RCIS candidates must identify sinus rhythms, atrial arrhythmias (atrial fibrillation, atrial flutter, supraventricular tachycardia), ventricular arrhythmias (premature ventricular contractions, ventricular tachycardia, ventricular fibrillation), heart blocks (first-degree, second-degree type I and II, third-degree), and pacemaker rhythms. Recognizing STEMI patterns on a 12-lead ECG and understanding which coronary artery territory corresponds to which ECG changes is also expected.
Catheterization procedures make up the largest portion of RCIS exam content. Candidates must understand the full range of diagnostic and interventional procedures performed in the cath lab, including coronary angiography, left heart catheterization, right heart catheterization (Swan-Ganz catheter), ventriculography, and aortography.
A diagnostic cardiac catheterization uses contrast injection and fluoroscopy to visualize the coronary arteries and cardiac chambers without physically altering anatomy. The procedure identifies the location and severity of coronary artery stenoses, evaluates valve function, and measures intracardiac pressures. An interventional catheterization, by contrast, uses therapeutic devices to treat disease — most commonly percutaneous coronary intervention (PCI), which involves advancing a balloon catheter and deploying a coronary stent to open a blocked or narrowed artery. PCI may be performed immediately following diagnostic angiography or as a planned staged procedure. RCIS exam questions test your ability to identify appropriate access sites, understand catheter selection, interpret angiographic findings, and assist with or describe interventional steps.
Common arterial access sites for cardiac catheterization include the femoral artery (transfemoral approach) and the radial artery (transradial approach). Transradial access has become increasingly preferred due to lower bleeding complication rates. Candidates must know how to assess radial artery patency using the Allen test, understand sheath sizing and catheter compatibility, recognize arterial access complications (hematoma, retroperitoneal bleed, radial artery spasm, arteriovenous fistula), and describe closure techniques including manual pressure, mechanical compression devices, and vascular closure devices.
Pharmacology is a dedicated content area on the RCIS exam. Candidates must know the mechanism of action, indications, dosing ranges, and reversal agents for the drugs most commonly used in the cath lab environment.
Unfractionated heparin (UFH) is the most common anticoagulant used during cardiac catheterization. Candidates must understand how to calculate weight-based heparin dosing, monitor activated clotting time (ACT) targets during PCI (typically 250 to 350 seconds), and recognize signs of heparin-induced thrombocytopenia (HIT). Bivalirudin is an alternative direct thrombin inhibitor with a shorter half-life and no HIT risk. Antiplatelet therapy with aspirin and P2Y12 inhibitors (clopidogrel, ticagrelor, prasugrel) is standard for PCI patients and the exam tests loading dose protocols and timing requirements.
Iodinated contrast agents are essential for visualizing coronary anatomy but carry a risk of contrast-induced nephropathy (CIN), particularly in patients with pre-existing chronic kidney disease, diabetes, or volume depletion. RCIS candidates must know contrast volume limits relative to estimated glomerular filtration rate (eGFR), pre-hydration protocols (intravenous normal saline before and after the procedure), and the use of N-acetylcysteine (NAC) — though evidence for NAC efficacy is mixed and varies by institutional protocol. Candidates should also know the difference between ionic and non-ionic contrast agents and why low-osmolar or iso-osmolar formulas are preferred in high-risk patients.
Cardiac catheterization laboratories use continuous fluoroscopic X-ray imaging, making radiation safety a critical competency for every cath lab team member. The RCIS exam tests your knowledge of radiation physics, dose measurement, occupational exposure limits, and the principles that govern radiation safety practice.
The ALARA (As Low As Reasonably Achievable) principle guides all decisions about radiation exposure in the cath lab. Practical ALARA techniques include maximizing the distance between the operator and the X-ray source (dose decreases with the square of distance), using the lowest fluoroscopy frame rate consistent with adequate imaging (7.5 frames per second vs. 15 or 30), collimating tightly to the region of interest, positioning the image intensifier close to the patient to minimize scatter, and using lead aprons, thyroid shields, and leaded glasses consistently.
RCIS candidates must understand how fluoroscopy equipment works, including the components of the X-ray tube, image intensifier vs. flat-panel detector systems, digital subtraction angiography (DSA) principles, and proper table positioning for oblique and cranial/caudal angulations used in coronary angiography. Hemodynamic monitoring equipment — pressure transducers, calibration procedures, and waveform interpretation — is also tested, as is the operation of intra-aortic balloon pumps (IABP) and temporary pacemakers, which RCIS technologists may assist in placing or managing during complex procedures.
Print the PDF and complete it under timed conditions — 200 questions in 3.5 hours gives you approximately one minute per question. Work through the full test without stopping, then score it by domain. If you missed more than two or three questions in any single content area, treat that domain as a priority for the next study cycle before attempting another full practice test.
The RCIS exam rewards candidates who understand the clinical rationale behind procedures, not just memorized facts. When you review wrong answers, trace the reasoning: why is a particular contrast volume limit set for a patient with a specific eGFR? Why does transradial access reduce bleeding risk compared to transfemoral? Why does the LAD territory show anterior ST changes on a 12-lead ECG? Building this explanatory understanding makes RCIS exam questions far more approachable than pure memorization.
CCI publishes an official RCIS exam content outline that specifies the percentage of exam questions from each domain. Study resources aligned to this outline — including CCI's own candidate handbook, cardiovascular anatomy and physiology textbooks, and cath lab procedure manuals — provide the most targeted preparation. Supplement textbook study with case-based learning from your own clinical experience whenever possible.
The RCIS credential validates the clinical skills you have built through years of cath lab experience and demonstrates to employers that you meet a nationally recognized professional standard. Structured exam preparation — combining practice tests, content review, and case-based reasoning — is the most reliable path to passing on your first attempt.
