Study Notes

Electrocardiogram (ECG)

A standard electrocardiogram (ECG) has 12 leads.

Cardiac Monitoring

Continuous electrocardiographic monitoring is used to observe a patient's heart rhythm and detect any abnormalities.

Cardiac Imaging

Echocardiography is an imaging technique that allows visualization of the heart on a screen.

Cardiac Stress Test

The purpose of a cardiac stress test is to evaluate the heart's function and blood flow under physical stress.

Echocardiography

The purpose of echocardiography is to create images of the heart to diagnose and monitor heart conditions.

Cholesterol Levels

A blood cholesterol level below 200 mg/dL is considered normal.
For men, a normal range for HDL (high-density lipoprotein) cholesterol is 40-50 mg/dL.
The normal range for LDL (low-density lipoprotein) cholesterol is below 100 mg/dL.
The normal range for triglycerides is below 150 mg/dL.

Prothrombin Time (PT)

The normal range for prothrombin time (PT) is 10-13 seconds.
