Chapter 5

Question 0

Asystole

Answer 0

When no rhythm or electrical current is traveling through the cardiac conduction system

Question 1

Apnea

Answer 1

The absence of breathing

Question 2

Atrial kick

Answer 2

When blood is ejected through into the ventricles by the atria immediately prior to ventricular systole

Question 3

Automaticicity

Answer 3

The ability of a cardiac cell to initiate an electrical impulse, without being stimulated by another source, causing a cardiac contraction

Question 4

Bigeminy

Answer 4

Pattern in which every other complex is a premature beat

Question 5

Biphasic

Answer 5

The waveform that has an equally positive and negative deflection on the ECG tracing

Question 6

Blocked or non conducted impulse

Answer 6

Impulse occurs too soon after the proceding impulse, causing a period when no other impulses can occur in the ventricles

Question 7

Bradycardia

Answer 7

A slow heart rate, usually less than 60 beats per minute

Question 8

Bundle branch block

Answer 8

Impulse is delayed or blocked within the bundle branches of the normal conduction pathway

Question 9

Capture

Answer 9

The ability of the heart muscle to respond to electrical stimulation and depolarize and myocardial tissue

Question 10

Cardiac output parameters

Answer 10

Observation guidelines used to assess the blood supply to the vital organs of the body to maintain normal function

Question 11

Electronic pacemaker

Answer 11

A device that deliver a small, measured amount of electrical energy to cause myocardial depolarization. Most artificial pacemakers are electronic

Question 12

Focus

Answer 12

A cardiac cell or group of cells that function as an ectopic beat

Question 13

Hypotension

Answer 13

Condition in which the patient’s blood pressure is not adequate to maintain good blood supply to the vital organs

Question 14

Inhibited

Answer 14

Electrical current is stopped from being sent to the myocardium

Question 15

Ischemia

Answer 15

Lack of blood supply to an area of tissue due to a blockage in the circulation to that area

Question 16

J point

Answer 16

A point on the QRS complex where the depolarization is completed and depolarization starts

Question 17

Loss of capture

Answer 17

The pacing activity continues to occur without evidence that the electrical activity has depolarizer or captured and myocardium

Question 18

Malsensing

Answer 18

The pacemaker does not recognize or sense the patient’s own inherent heartbeats

Question 19

Neurological

Answer 19

Pertaining to the nervous system, it’s diseases, and its functions

Question 20

Oversensing

Answer 20

The pacemaker senses electrical current from other muscle movements or electrical activity outside of e body as the patient’s heart electrical current

Question 21

Pacemaker competition

Answer 21

Competition between the pacemaker generator and the heart’s inherent rate over control of the myocardium

Question 22

Pacemaker malfunctioning

Answer 22

The pacemaker fails to send an electrical impulse to the myocardium at the predetermined interval

Question 23

Palpitations

Answer 23

Fast, irregular heartbeat sensation felt by the patient, which may or may not be associated with complaints of chest pain

Question 24

Quadgeminy

Answer 24

Pattern in which every fourth complex is a premature beat

Question 25

Supraventricular

Answer 25

An ectopic focus originating above the ventricles I the atria or junctional region of the heart

Question 26

Syncope

Answer 26

Condition when the patient loss consciousness

Question 27

Tachycardia

Answer 27

A fast heart rate, usually greater than 100 beats per minute

Question 28

Trigeminy

Answer 28

Pattern in which every third complex is a premature beat

Question 29

Triggered

Answer 29

Electrical current is sent from the pacemaker generator to the myocardium to cause the depolarization of the myocardial tissue

Question 30

Vagal tone

Answer 30

Condition in which impulses over the vagus nerve exert a continuous inhibitory effect upon the heart and cause a decrease in heart rate
