An apparatus that measures work or energy used during a period of physical exercise:
Ergometer
What are beta blockers — usually drugs with names ending in "lol" — used for?
To reduce heart rate
What is atropine (positive chronotropic) used for?
To increase heart rate
What is digitalis (positive inotropic) — i.e. digoxin or Lanoxin used for?
Heart failure patients. This helps heart pump more effectively
What are some of the EKG manifestations of myocardial ischemia?
- ST elevation — think STEMI!
- Flat or down-sloping ST depression of 1.0 mm or more
- Fixed Q waves in established ischemia
- T wave inversion
What are the indications for a pharmacological (rather than exercise) stress test?
- Reduced functional capacity causing an inability to exercise
- Reliance on medications that could affect the outcome of an exercise test.
Give examples of drugs which are both negative chronotropic and negative inotropic:
Beta blockers, and non-hydropyridine calcium channel blockers, i.e. diltiazem and verapamil.
What is MET — metabolic equivalent of task?
A measure of exercise intensity based on oxygen consumption
The amount of oxygen (O2) a person consumes per unit of body weight during 1 min of rest — set at 3.5ml O2 per kilogram per minute at rest.
Which region do leads II, III and AVF show?
Inferior
What are some of the criteria of a negative stress test?
- No abnormalities in the ST-segment or J-point
- The patient attains at least 85% of their maximum target heart rate
- No signs of coronary artery disease
- No angina symptoms
What does the arm ergometer stress test involve?
The patient is seated with handles of the ergometer positioned at chest level
- The target heart rate for the patient is the same as for other forms of stress testing
- It is less sensitive than leg exercise in detecting cardiovascular abnormalities
What is sinoatrial (SA) block?
It is a disorder of the cardiac conduction system where the SA node fails to generate an impulse, and no P wave is seen on an EKG. It may occur only occasionally and cause the patient no symptoms or problems.

Certification renewal
According to (Cardiovascular Credentialing International) CCI official website, After passing a CCI exam, a credential is active for 9–12 months. As the new registrant (credential holder) there are two types of renewal with CCI:
- First renewal
- Second renewal/first triennial
Recommended books
CCI's official website recommends the following sources to help you prepare for the exam.
- Shier, David, Jackie Butler, and Ricki Lewis. Hole’s Essentials of Human Anatomy and Physiology. Boston: McGraw-Hill.
- Dubin, Dale. Rapid interpretation of EKG’s: an interactive course. 6th ed. Tampa, Fla.: Cover Pub. Co., 2000.
- Booth, Kathryn A., and Thomas E. O’Brien. Electrocardiography for Healthcare Professionals. New York: McGraw-Hill.
