The most common nonmedical term for a myocardial infacrtion is?
heart attack
-
The cardiac stress test (treadmill) is?
Exercise electrocardiography that is done to determine if the heart is reciiving enough blood during exercise
-
What are augmented leads?
Leads that measure cardiac activity from one electrode on the body at a time.
-
What are artifacts?
Unwanted changes in an ECG tracing caused by movement, machine malfunction, or other factors
-
Name the heart condition in which the heartbeat is too rapid, and give the heart rate.

-
A device on the skin that picks up electical impules given off by the heart is known as an?
Electrode(s)
-
What is the name given to the modified myocardial cells that set the pace of the heart?
SA Node
-
Stylus
Heated device that records the heart's activity on heat-sensative graph paper
-
ECG
Graphic picture of the hearts electircal activity
-
Wandering baseline
Shift on the ECG tracing from the baseline or center of the paper
-
Amplifier
Device on the electrocardiograph that magnifies or enlarges the heart's electrical impulses so they can be recorded
-
Alternating current
Electrical intereference that appears as small, uniform spikes on ECG tracing
-
Baseline
The flat horizontal that separates the various waves
-
Pacemaker
Device that delivers electrical impulses to the heart muscle when the SA Node is unable to do so.
-
Ventricular Tachycardia
Three or more consecutive PVCs with heart rate exceeding 100 beats per min
-
U-Wave
Normal, small upward curve that occassionally follows a complete ECG cycle after the PQRST; has unknown indication
-
Ischemia
Poor blood supply to body tissue causing a lack of oxygen to that tissue
-
Cardiac Cycle
one heartbeat, one contraction/relaxation phase of the heart
-
Premature Atrial Contraction (PAC)
Conditioin in which an electrical impulse in the atria starts before the next expected heartbeat
-
Arrythmia
Abnormal heart rate, rhythm, and conduction system
