Rhythms

Question 1

____ ____ is upward- the SA mode firing which causes atrial contraction.

Answer 1

P wave

Question 2

___ ___ - the time it takes to travel through SA node pathway to AV node is called

Answer 2

PR interval

Question 3

___ ___ - impulse is traveling through bundle of his, bundle branches and purkinje fibers

Answer 3

QRS complex

Question 4

__ ___ - repolarization of ventricles

Answer 4

T wave

Question 5

ST depression means

Answer 5

Ischemia

Question 6

ST elevation means

Answer 6

Muscle damage

Question 7

__ ___ indicates the repolarization of the ventricles

Answer 7

ST segment

Question 8

Heart has a fail system what is it

Answer 8

If SA fails, then AV Takes over; if AV fails ventricles take over. Heart rate is slower caller Ectopic focus

Question 9

Most common cause of arrhythmia

Answer 9

Ischemic heart disease

Question 10

Low or high potassium can cause arrhythmia

Answer 10

Know

Question 11

Tx for sinus bradycardia

Answer 11

IV atropine sulfate

Normal in athletes

Question 12

Dangerously fast heart beats greater than 150 bpm.

Answer 12

Super ventricular tachycardia SVT

Question 13

Tx of SVT

Answer 13

Digitalis/Ca channel & adrenergic blockers to slow HR

Cardiac output drops, can lead to heart failure

Question 14

Impulse outside SA node causes atria to contract at very rapid rate 2-400bpm

AV node can only conduct some of the impulses to ventricles *Sawtooth flutter waves on EKG

Answer 14

Atrial flutter

Question 15

Greater than 400 Bpm- atria just quiver do not contract.

Blood clots may form in atria, poor cardiac output

Answer 15

Atrial fibrillation

Question 16

TX of A Fib

Answer 16

Digitalis, verapamil, propranolol, cardioversion, chemical use, Ibutilide & aspirin and warfarin

Question 17

Abnormal slowing of electrical impulses through AV node.

Answer 17

AV node dysrhythmia

1 & 2 the impulse is delayed.
3rd=complete- the impulse does not get through and ventricles develop their own rhythm-30bpm- tx is pacemaker

Question 18

Tx for ventricular dysrhythmia

Answer 18

IV lidocaine bolus then drip

Numbs heart and ventricles

Question 19

In ____ ___ the ventricles are initiating the heartbeat 150-200 bpm.

Decreased cardiac output- may pass out or be pulse less

May stop abruptly or require defib

Answer 19

Ventricular tachycardia

Question 20

Rapid irregular twitching of the ventricles

“Dying heart rhythm”

Most dangerous arrhythmia

Answer 20

Ventricular fibrillation

Question 21

Tx of ventricular fibrillation

Answer 21

CPR-immediate Defibb- epinephrine

Question 22

___ ___ -force and volume of blood of ejection of P ventricle-reflects ability of arterial system to distant with ventricular contraction

Answer 22

Systolic Bp

Question 23

___ ___ -pressure in our arteries during ventricular relaxation

Answer 23

Diastolic BP

Question 24

Reg of BP consists of

Answer 24

Baroreceptors
Chemoreceptors
ANS
Renal- by renin- angiotensin/aldosterone

Question 25

BP greater than 120/80 is called

Answer 25

Prehypertension

Question 26

Increased BP has caused cardiac Abnormality is called

Answer 26

Hypertensive heart disease

Question 27

Vascular damage without heart involvement is called

Answer 27

Hypertensive vascular disease

Question 28

Both heart and vascular disease

Answer 28

Hypertensive cardiovascular disease

Question 29

Potassium level

Answer 29

3.5-5.0

Question 30

NA level

Answer 30

135-145

Question 31

CL level

Answer 31

98-107

Question 32

Mag level

Answer 32

1.6-2.6

Question 33

Hc03 level

Answer 33

22-26
