What does this EKG show?

complete heart block

 

p waves show no relation to the QRS complexes

62

What does this EKG show?

sinus pause = longer than 2 seconds of no sinus activity = 10 big boxes

63

What does this EKG show?

electronic pacemaker spikes = artificially induced electronic stimuli that pace pts rhythm cause a blip or spike on the waveform

64

What is this patient's most likely K level


A)4.5
B)5.0
C)5.5
D)6.5
E)8.5
 

mostly likely has 6.5

- peaked T waves mean K . 5.5

- loss of p waves mean K > 6.5

- but if 8.5 would have had wider QRS

65

Identify 3 ECG findings inidicative of possible hyperkalemia? Give what med?

- peaked T waves

- first degree AV block

- wide QRS

 

give IV calcium

66

What caused this EKG pattern?

hypokalemia = promiment U waves in V2/V3

67

What likely caused this EKG pattern?

acute pericarditis 

= diffuse ST elevation, concave upwards, PR depression in V3

- may be tachycardic

68

What EKG finding is this?

electrical alternans

= QRS axis or amplitude alternates between beats

may be due to pericarditis or tamponade with fluid surrounding heart

69

What caused this EKG finding

Pulmonary embolism

 

S1Q3T3 pattern

- prominent S wave in lead I

- Q wave and inverted T wave in lead III

- sinus tachycardia

- T wave inversion in V1-V3

70

What caused this EKG finding?

digoxin effect = reverse tick/check sign = sagging ST

71

What kind of rhythm is this?

 

What is dysfunctioning here?

sinus bradycardia

 

represents dysfunction at SA node

72

What kind of rhythm is this?

 

What is dysfunctioning?

Sinus tachycardia

 

this is dysfunctional SA node

73

What kind of rhythm is this?

 

What causes this?

Supraventricular tachycardia

narrow QRS, fast, P waves not super distinct

reflects reentry through AV node

74

What does this rhythm show?

premature ventricular contractions

 

wide QRS from ventricles; two different shaped PVC means multiple ectopic foci
