15: Antidysrhythmic Drugs

Question 0

Asystole

Answer 0

And absence of electrical or contraction activity within the heart. Appears on the electrocardiogram monitor as a straight line or flatline

Question 1

Antidysrhythmic drugs

Answer 1

Drugs used to treat abnormal heart rhythm

Question 2

Atrial fibrillation

Answer 2

Quivering of the atria. Atrial fibrillation decreases cardiac output because the atrial portion of the output of the heart is lost when the Atria does not contract

Question 3

Atrioventricular (AV) node

Answer 3

Specialized cardiac tissue capable of generating electrical impulses that caused her to contract, the secondary pacemaker of the heart

Question 4

Automaticity

Answer 4

The ability of the cardiac muscle cells to fire an impulse on their own

Question 5

Bradycardia

Answer 5

Slow heart rate, usually considered to be less than 60 bpm

Question 6

Bradydysrhythmia

Answer 6

And abnormally slow heart rhythm

Question 7

Cardiac output

Answer 7

The amount of blood ejected by the heart in one minute. Normal adult her can easily 5 quarts of blood in a minute.

Question 8

Conductivity

Answer 8

Ability or power of the heart muscle cells to transmit electrical impulses

Question 9

Dysrhythmia

Answer 9

An abnormal heart rhythm

Question 10

Electrical conduction system

Answer 10

The electrical conduction system that controls the heart rate. It causes electrical impulses and conducts them through the muscle of the heart, stimulating the heart to contract and pump blood.

Question 11

His-Purkinje system

Answer 11

Specialize cardiac tissue that normally conduct impulses from the AV node to the ventricles

Question 12

Normal sinus rhythm

Answer 12

The normal rhythm of the heart as measured by an electrocardiogram

Question 13

Pacemaker

Answer 13

A part of the body such as the special cardiac muscle fibers of the sinoatrial node that sets the rate of rhythm of the heart

Question 14

Premature contractions

Answer 14

Heart contractions that occurred earlier than expected

Question 15

Refractory period

Answer 15

The time following an action potential during which normal stimulation will not cause another action potential.

Question 16

Sinoatrial (SA) node

Answer 16

Specialized cardiac tissue capable of generating electrical impulses that caused the heart muscle to contract, the normal pacemaker of the heart located in the upper right atrium.

Question 17

Syncope

Answer 17

A brief loss of consciousness caused by a temporary deficiency of oxygen in the brain

Question 18

Tachycardia

Answer 18

Rapid heart rate, usually considered to be greater than 100 bpm

Question 19

Tachydysrhythmias

Answer 19

An abnormally rapid heart rhythm

Question 20

Tirades de pointes

Answer 20

A life-threatening ventricular tachycardia. Primarily caused by a little blood magnesium level and seeing and malnourished people

Question 21

Ventricular fibrillation

Answer 21

Quivering of the ventricles. Ventricular fibrillation is life-threatening and can lead to death and minutes because there is no cardiac output when the ventricles do not contract
