ECG images

Question 1

What is this ecg showing?

Answer 1

normal sinus rhthym

regular with normal P, Q-R-S, T deflectionsa nd intervals. rate = 60-100 at rest

Question 2

What is the ecg showing?

Answer 2

2nd degree heart block: mobitz -II

characterized by iregular R-R interval

rhythm interpretation: patient will need a pacemaker, and not eligible for exercise or PT that day

Question 3

interpert this ECG

Answer 3

first degree AV block

prolonged P-R interval

signals from atra to ventricle is delayed, causing an increased delay between atra and ventricular depolarization

Question 4

is a first degree AV block a rebular or irregular ecg?

Answer 4

regular

Question 5

PT’s response to first degree AV block

Answer 5

continue to monitor vitals
consutls with PCP about medications
observation of worsening heart block
often benign

Question 6

What is the ECG

Answer 6

premature ventricular contraction - uniform

presence of ectopic focus occuring in ventricular walls

fires permaturely before the SA node

Question 7

is premature ventricular contraction a regular or irregular heart rhythm?

Answer 7

irregular

can be life theatening if; triplets are present, more the 6 PVC’s in 1 minute (send to er)

Question 8

Interpert this ECG

Answer 8

third degree heart block

rhythm is regular

no relationship between the P and QRS waves, P to P intervalsare regular but no relationship to QRS complexes

Question 9

can you treat a patient with third degree heart block?

Answer 9

no! medical emergency

Question 10

Why is this ecg sinus tachycardia (main indictors)

Answer 10

indicated by a heart rate greater than 100 beats per minute, along with a normal, upright P wave in lead II preceding every QRS complex. The P wave should be normal in morphology and consistent, indicating the heart’s natural pacemaker (the sinus node) is firing at an increased rate.

Question 11

interpert this ecg

Answer 11

sinus bradycardia

rate: 39 bpm

regular rhythm- intervals are normal, QRS is identical, P waves symmetrical

Question 12

intepret ecg

Answer 12

ventricular fibrillation

rate: 430 bpm

lower ventricles are quivering and movely rapidley and uncoordinated. preventing heart from pumping bloodeffectively. next stage = cardiac death

Question 13

is ventricular fibrillation a medical emegency?

Answer 13

yes; emergency respone, do CPF and defibrillation immediately

Question 14

what is the ecg showing

Answer 14

wandering pacemakers

regular rhythm but can present irregular

commonly found accidently during EKG screenings

Question 15

interpret this rhythm

Answer 15

irregular wandering pacemaker

Question 16

Answer 16

2nd degree AV heart block (mobitz-1 or wenkebach)

Question 17

is 2nd degree AV heart block (mobitz 1 or wenkebach) a regular or irregular rhythm?

Answer 17

irregular

cause - infarction (LAD), P wave progressively gets longer until it skips QRS

Question 18

What is this rhythm

Answer 18

atrial fibrillation

atria quivers quickly and randomly

no waves before QRS comlex with a very irregular HR Rate: 140 bpm

Question 19

is atrial fibrillation a red flag?

Answer 19

no, yellow flag

pt response:
- can by asymptomtic, watch for overexertion during exercise, and check vitals regularly

symptoms: fast HR, chest pain, SOB, fatigue, dizziness

Question 20

What is this rhythm

Answer 20

atrial flutter

HR range: 250-400 bpm

p waves have an identical “sawtooth” pattern, more than 1 P wave fore very QRS, R-R interval may vary due to abnormal P:QRS ratio

Question 21

what can atrial flutter lead to?

Answer 21

atrial fibrillation

Question 22

PT response to atrial flutter

Answer 22

hold off on Pt - they may feel faint, could lead to an embolism (PE or stroke)
