EKG Rhythm Interpretation Practice

Question 1

Answer 1

Normal sinus rhythm

Question 2

Answer 2

Sinus bradycardia

Question 3

Answer 3

Atrial flutter

Is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit in the heart causes the upper chambers (atria) to pump very rapidly; important consequence is stroke

Question 4

Answer 4

SVT

Supraventricular tachycardia (SVT) is an irregularly fast or erratic heartbeat. It occurs when faulty electrical signaling in the heart set off a series of early beats in the upper chambers of the heart.

Question 5

Answer 5

WPW

Wolff-Parkinson-White (WPW) syndrome is a congenital cardiac preexcitation syndrome that arises from abnormal cardiac electrical conduction through an accessory pathway that can result in symptomatic and life-threatening arrhythmias.

Question 6

Answer 6

PVC in trigeminy

Question 7

Answer 7

Monomorphic VT

Ventricular tachycardia (VT) is a fast, abnormal heart rhythm (arrhythmia). It starts in your heart’s lower chambers, called the ventricles. VT is defined as 3 or more heartbeats in a row, at a rate of more than 100 beats a minute.

Question 8

Answer 8

Torsades des pointes

TdP is a type of polymorphic ventricular tachycardia characterized on electrocardiogram by oscillatory changes in amplitude of the QRS complexes around the isoelectric line.

Question 9

Answer 9

Ventricular standstill vs low amplitude

Ventricular standstill (VS) is a rare electrophysiological abnormality. The name describes what happens — the heart stops beating and stands perfectly still. No blood is pumped and the results are the same as ventricular fibrillation (VFib).

Question 10

Answer 10

R on T shock

An R on T premature ventricular complex (PVC) is an important concept in ECG reading as it may lead to ventricular tachycardia, ventricular fibrillation, and possibly sudden cardiac death; associated with QTc prolongation

Question 11

Answer 11

Ventricular fibrillation

VF is an arrhythmia that starts in your ventricle

Question 12

Answer 12

Right atrial enlargement

Question 13

Answer 13

LVH with LBBB

Question 14

Answer 14

Idioventricular

Idioventricular rhythm is a slow regular ventricular rhythm with a rate of less than 50 bpm, absence of P waves, and a prolonged QRS interval

Question 15

Answer 15

SVT

Question 16

Answer 16

Electrolyte - hyperkalemia

Question 17

Answer 17

2:1 atrioventricular block Mobitz type 2

Question 18

Answer 18

Atrial flutter

Question 19

Answer 19

Adenosine use

Question 20

Answer 20

Atrial fibrillation

Question 21

Answer 21

2-AVB Mobitz type 1

Question 22

Answer 22

2-AVB Mobitz type 2

Question 23

Answer 23

Pre-excited afib

Question 24

Answer 24

VT

Question 25

Answer 25

Afib SVR

Question 26

Answer 26

Afib RVR with DCCV (DC cardioversion)

Question 27

Answer 27

1-atrioventricular block

Question 28

Answer 28

Idioventricular vs afib with complete heart block

Idioventricular rhythm is a slow regular ventricular rhythm with a rate of less than 50 bpm, absence of P waves, and a prolonged QRS interval

Question 29

Answer 29

1-atrioventricular block with PAC

Question 30

Answer 30

VT with ATP (antitachycardia pacing)

Question 31

Answer 31

Monomorphic PVC with NSVT

Question 32

Answer 32

A-sense V-pace; left atrial enlargement

Atrial sensed Ventricular paced: used when the patient has a good sinus node function but poor AV node conduction

Question 33

Answer 33

3-atrioventricular block; question neuro or ischemic T-waves

Question 34

Answer 34

Normal sinus
