Medical Terminology Quiz Arrythmia/stroke

Front 1

Sinoatrial Node

Back 1

The SA node is the heart's natural pacemaker. The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart).

Front 2

Atrioventricular Node

Back 2

AV node: An electrical relay station between the atria (the upper) and the ventricles (the lower chambers of the heart). Electrical signals from the atria must pass through the AV node to reach the ventricles

Front 3

Torsades de Pointes

Back 3

Paroxsymal polymorphic ventricular tachycardia characterized on the EKG by twisting ORS morphology

Front 4

Atrial fibrillation

Back 4

AF is a supraventricular tachyarrhythmia characterized by uncoordinated atrial activation leading to an irregular irregular ventricular rate with consequent deterioration of mechanical function

Front 5

INR

Back 5

International normalized ratio. The lab value used to monitor oral anticoagulant therapy that standardizes thromboplastin reagents in order to interpret the prothrombin time.

Front 6

Stroke

Back 6

A sudden loss of neurological function cause by ventricular injury to the brain that lasts > 24 hours and is associated with neurological deficit.

Front 7

TIA

Back 7

Transient ischemic attack. A sudden focal loss of neurological function cause by vascular injury to the brain that lasts < 24 hours and is not associated with neurological deficit.

Front 8

Aphasia

Back 8

Difficulty speaking or understanding speech

Front 9

Implantable Cardioverter-defibrillator

Back 9

Used to prevent sudden death in patients with previous cardiac arrest or sustained ventricular arrythmias

Front 10

Diplopia

Back 10

Double vision

Front 11

Action Potential Phase 0

Back 11

Rapid depolarization signaled from the SA and AV node

Front 12

Action Potential Phase 1

Back 12

Initial or partial repolarization

Front 13

Action Potential Phase 2

Back 13

Plateau Phase

Front 14

Action Potential Phase 3

Back 14

Repolarization

Front 15

Action Potential Phase 4

Back 15

Rest or spontaneous (or pacemaker) depolarization
