1. What type of problem did the patient
have before coming to the ER? ………..
A. Chest pain
B. Low blood pressure
C. High blood pressure
D. Rapid heartbeat
2. What did the EMTs do for the patient?
A. They administered an electrocardiogram
and put him on a heart monitor
B. They administered a drug to reverse his
arrhythmia
C. They checked his cardiac enzymes and got
him to the hospital
D. They shocked his heart into a normal rhythm
3. What is a sinus rhythm? …………………
A. A normal heart rhythm
B. A rapid heartbeat
C. A very slow heartbeat
D. An abnormal heartbeat caused by
respiratory problems
4. ST and T waves are elements of: ………
A. An EEG
B. An ECG
C. A cardiac scan
D. Echocardiography
B. Patient Assessment
The patient is a 58-year-old male who has had angina for 3 years. His symptom of substernal
(stern/o means breastbone) tightness occurs with exertion and is relieved promptly by rest (typical
of angina). A treadmill stress test showed definite ST segment abnormalities consistent with
myocardial ischemia at stage 3 of the test. In addition, the patient has multiple risk factors including
hypertension, hypercholesterolemia, and history of smoking.
I have started the patient on Cardizem (a calcium channel blocker) as antianginal medication.
If the patient has evidence of significant stenosis in the future, he should undergo coronary
angiography and possibly PCI.

PRACTICAL APPLICATIONS
Name: ______________________________
A. Emergency Room—Patient Report
Mr. Smith was seen by the emergency medical technicians (EMTs) and found to have tachycardia.
Lidocaine (a cardiac antiarrhythmic) was started and by the time he reached the ER his heart rate
was between 75 and 80 with a sinus rhythm. He had excellent ST segments and T waves. Blood
pressure was 156/88. He had a good carotid pulse bilaterally. No cardiomegaly and no murmurs.
He was started on a cardiac monitor and observed for any ECG change. He had no episode of
hypotension and no further arrhythmia. There was no evidence to do cardiac enzyme studies, and
the patient was discharged to be followed by his regular physician.
1. What is the patient’s major symptom?
A. Pain in his left arm
B. High blood pressure
C. High blood levels of cholesterol
D. Chest pain
2. What did the treadmill test show? …….
A. Hypertension
B. Decrease in blood flow to heart muscle
C. Fracture of the breastbone
D. History of smoking
3. What is the effect of Cardizem? ………..
A. Increases blood pressure
B. Lowers blood cholesterol
C. Decreases myocardial ischemia
D. Promotes aortic stenosis
4. What procedures are recommended? …
A. X-ray of heart blood vessels and balloon
angioplasty with stent placement
B. Coronary artery bypass surgery
C. Thrombolytic therapy
D. Exercise tolerance test and radioactive scan
