|
Myocardial infarction (MI) |
An occlusion of the coronary arteries that prevents oxygenated blood from circulating within the heart; causing permanent heart muscle tissue damage. |
|
|
P prime (P') |
A term used to represent a P wave that originated from anywhere other than from the sinoatrial (SA) node. |
|
|
Pacemaker |
A device that measures the movement of electricity in the heart; designed to provide an electrical stimulus in the event that the heart does not provide a normal heartbeat. |
|
|
Pacing electrode |
Single or multiple leads that can be unipolar or bipolar, and can provide the electrical stimulus in a pacemaker. |
|
|
Polymorphic |
Waveforms with changing polarity. |
|
|
Pulseless electrical activity (PEA) |
A condition where the heart muscle cannot contract, even though electrical activity appears on the ECG. |
|
|
Retrograde |
An impulse that goes backward in the conduction path. |
|
|
Sudden cardiac arrest |
Unexpected death due to a heart electrical system malfunction. |
|
|
Supraventricular tachycardia (SVT) |
Occurs when the electrical system above the ventricles sends abnormal impulses that interfere with sinoatrial (SA) node impulses, creating a very fast heart rate that begins and ends suddenly. |
|
|
Terminal rhythm |
A continuous rhythm that cannot reverse to a normal rhythm without medical intervention. |
|
|
Underlying rhythm |
A review of an overall rhythm on the ECG when an abnormally is not included in the rhythm; for example, a review of the ECG without including an ectopic beat to see if it is otherwise a normal rhythm. |
|
|
Ventricular fibrillation (V-Fib) |
Chaotic indistinguishable waves caused by multiple ectopic and reentry patterns originating from many different areas in the ventricular walls. |
