An EKG application used to evaluate how the heart functions under controlled. Stress created either by exercise or medications (pharmacologic stress test) ; also called exercise stress test, exercise tolerance test and treadmill test
Stress test
A common type of electrocardiogram that records the electrical activity of the heart in 12 different directions ( leads )
12-lead EKG
A type of ambulatory monitor that detects heart rate or rhythm irregularities automatically and transmits data to a healthcare professional when an irregularities occurs
Mobile cardiac telemetry
A type of ambulatory monitor that records heart rate and rhythm when the patient indicates that she is experiencing symptoms.
Event monitor
A type of ambulatory monitor that allows a doctor to evaluate heart rate and rhythm over an extended period of time (usually 24-48 hours) while the patient continues with normal life.
Holter monitor
A type of EKG technology that can record or monitor a patient's heart rate and rhythm over an extended period while the patient continues with normal life; holter, event, and mobile telemetry monitors are examples.
Ambulatory monitor
A application of EKG technology that allows continual monitoring of a patient heart rate and rhythm; often used in an emergency room or hospital setting
Telemetry
Difference in electrical charge
Voltage
A test that uses sound waves to visualize the heart ; provides information about the mechanical function of the heart
Echocardiogram
Record of the electrical activity of a patients heart during a electrocardiogram as a recorded by an EKG machine; also called EKG strip or rhythm strip
EKG tracing
In a EKG an imaginary the lines between two electrodes attached to the patient; each lead can produce a different EKG tracing and a different view of the hearts electrical activity
Leads
Wires that connect electrodes placed on a patients body to an EKG machine; also called lead wires or electrodes
Leads wires
In EKG technology, pads that conduct electricity and are connected to the patient's body and to electrodes cables to conduct electrical signals from the heart to the EKG machine
Electrodes
An electrical change in the heart in which the voltage of the cells become more negative and the cells relax
Repolarization
An electrical change in the heart in which the voltage of the cells becomes more positive and the cells contract
Depolarization
A rare heart condition that causes the heart to develop to the right side of the chest instead of the left side
Dextrocardia
EKG artifact that occurs when signal is compromised by frayed or faulty lead wires
Broken recording
In electrocardiography, a 12 second recording of the activity in ii on an EKG tracing
Rhythm strip
In electrocardiography, the lead group made up of leads I, II and III; also known as bipolar leads
Limb leads
The imaginary triangle formed by the placement of the electrodes that records the limb leads
Einthoven's Triangle
In electrocardiography, the unipolar lead grouped composed leads V1,V2 V3 v4 v5 v6 also know as the chest leads
Precordial leads
In electrocardiography, leads that measure voltage at an electrical positive poll in comparison to a neutral reference point
Unipolar leads
In electrocardiography, the collective name for leads AVR, AVL and AVF
Augmented limb leads
The center of Einthoven triangle ; acts as an electrically neutral point of reference for the precordial ( chest ) leads
Wilson Central Terminal
An electrocardiography, inference or distortion that appears on a tracing
Artifact
