arrythmias

Question 1

describe sinus bradycardia

Answer 1

normal ekg tracing, but with less than 60 bpm

Question 2

describe sinus tachycardia

Answer 2

normal ekg tracing, but with over 100 bpm

Question 3

describe sinus dysrithima

Answer 3

slight irregular in the rhythm. assosiated with normal breathing patterns

Question 4

describe sinus arrest

Answer 4

break in the ekg pattern. the sa node did not fire.

Question 5

what does “sinus” suggest

Answer 5

sa node

Question 6

describe atrial flutter

Answer 6

more severe then sinus arrythmias. the atria is contracting faster then the ventrials can

Question 7

describe atrial fibrillation

Answer 7

more serious than atrial flutter, there is no organized contraction, and blood clots are likely due to the quivering.

Question 8

where does junctional arrhythmias occure

Answer 8

@ the av node/ tissue

Question 9

when does the av node make impuslses

Answer 9

when the sa node has been damaged

Question 10

describe premature junctional complex

Answer 10

early impulse before the next expected beat. makes the p wave before, during, or after the qrs complex.

Question 11

describe junctional escape rhythms

Answer 11

pulse from av node acting as the backup pacemaker. absent p wave or inverted. heart rate wont go above 60bpm

Question 12

accelerated junctional rhythm

Answer 12

same as escape, but the heart rate will be 60-100 bpm

Question 13

junctional tachycardia rhythm

Answer 13

same as escape and accelerated, but heart rate will be 100-150 bpm.

Question 14

supraventricular tachycardia or narrow complex tachycardia

Answer 14

not nessicarly junctional, but impluse does come from above the ventricles. p wave is not visable.

Question 15

ventricular arrhythmias are typically…

Answer 15

urgent and life threatening

Question 16

describe premature ventricular complex

Answer 16

ventricles contract out of the ordinary. p wave not present, qrs is wide and unusual shape, palpatations.

Question 17

describe ventricular tachycardia

Answer 17

3 or more pvs in a row, w ventricular rate over 100/min. no p wave, qrs wide, unusual w/ deflection opposite direction

Question 18

describe ventricular fibrilation

Answer 18

emergency. ventriulars arent contracting, but are quivering. no cardiac output, no waves.

Question 19

describe idioventricular rhythm

Answer 19

only ventricular pace maker is functioning. no p wave, qrs complex wide and unusual

Question 20

describe agonal rhythm

Answer 20

all pacemakers fail. wide, unusual qrs with no p or t wave

Question 21

heart blocks

Answer 21

block in electrical conduction system pathway

Question 22

bundle branch block

Answer 22

interference somewhere in one of the bundle branches

Question 23

1st degree ventrucular block

Answer 23

block between sa and the av nodes. pr interval will be longer

Question 24

2nd degree ventricular block- type 1

Answer 24

blocked impulses from av to ventricals. missing the qrs complex. pr interval gets progressibly longer till qrs drops, and the cycle repeats

Question 25

2nd degree atriaventricular block, type 2

Answer 25

pr interval is constant, during tracing p wave is present with no qrs complex or t wave. quickly progresses to complete heart block.

Question 25

third degree atrial ventrucluar block

Answer 25

complete heart block. all impulses above the ventricles are blocked, with no pattern.

Question 26

what causes intrutupeted baselines

Answer 26

damaged cable
