shift on the EKG tracing from the baseline or center of the paper | wandering baseline |
cardiac cycle | one heart beat |
baseline | the line that separates the various cardiac waves |
ventricular tachycardia three or more consecutive premature ventricular contractions with the heart rate above | 100BPM |
electrocardiograph | a machine that records the electrical activity of the heart |
U wave | small upward curve that occasionally follows a complete ECG cycle after the PQRS interval |
altering current | electrical interference that appears as small, uniformed spikes on an EKG tracing |
arrhythmia | abnormal heart rate |
pacemaker | a device that delivers electrical impulses to the heart when the SA node fails |
stylus | heated device that records the hearts activity on heat sensitive paper |
premature atrial contraction | condition in which an electrical impulse in the atria starts before the next expected heart beat |
ischemia | a condition of poor blood supply to body tissues causing a lack of O2 to be delivered to the tissues |
amplifier | a device on the EKG that magnifies the hearts electrical impulses so they can be recorded |
Electrical stimulation of the ventricular tissue takes place in the | purkinje fibers |
The precordial leads include | V1-V6 |
If the SA node does not stimulate electrical impulses in the heart, this function is usually taken over by the | AV node |
Electrocardiograms are usually recorded with the ECG paper moving at the speed of | 25mm/second |
What chest lead is locate on the 4th intercostal space left of the sternum | V2 |
The aVR, aVL, and aVF leads are called | augmented leads |
The portion of the electrocardiogram (ECG) that relates to ventricular depolarization is the | QRS Complex |
Leads I, II, and III are called | standard/bipolar |
In lead I, activity of the heart is being measured from the | right arm to the left arm |

Electrocardiograph paper is | heat sensitive |
When no abnormalities show during a resting ECG, the physician may order an exercise ECG, Another name for this test is | stress test |
Making certain that an ECG taken on one machine will compare to a tracing taken on another machine is called | standardized |

An exercise tolerance test is also known as a | cardiac stress test |
Which wave represents re-polarization | T wave |
Interference picked up by the ECG machine is known as | artifact |
What is the name given to the modified myocardial cells that set the pace of the heart | SA node |
A device on the skin that picks up electrical impulses given off by the heart is known as a | electrode |
Any deviation from “normal” on the electrocardiogram (ECG) tracing originating from the patient’s heart is known as | arrhythmia |
What records the electrical activity of the heart | EKG/ECG |
The flat horizontal line that separates the various waves is known as | baseline |
