Stop exercise immediately with all of the following except:
Ventricular tachycardia
Second degree AV block Type 2
Atrial fibrillation
Ventricular fibrillation
Primary blood supply to the AV node and SA node:
Right coronary artery
Left coronary artery
Circumflex artery
Left anterior descending artery
All the following are correct inherent beats except:
SA node at 100-110 bpm
SA node at 60-80 bpm
AV node at 40-60 bpm
Bundle of His at 20-40 bpm
What is the correct order in which heart sounds are heard?
S1, S2, S3, S4
S4, S1, S2, S3
S1, S4, S2, S3
S3, S1, S2, S4
Which heart sound may disappear when a patient sits up or stands and is considered abnormal in adults over 40 y/o?
S1
S4
S3
S2
All of the following cause splits except:
Bundle branch block
Ventral septal defect
Irritable foci
Valve dysfunction or blood flow alterations
You are listening to a 6 y/o female heart beat and notice the rate increases with inspiration and decreases with expiration. She has no other s/s. What do you do?
Nothing, this can be a normal finding for this age
Administer nitroglycerin tablets to the patient
Immediately transport the patient to the ER
Stop treatment and reschedule for another day
A patient’s ECG shows a PR interval < 0.12 and a regular QRS rate > 100. The patient presents with a rapid and regular pulse and decreased cardiac output. This patient has what type of arrhythmia?
Wandering atrial pacemaker
Atrial premature beat
Atrial tachycardia
Atrial flutter
Individuals with atrial fibrillation are at increased risk of stroke because:
There is less blood supply to the brain
The heart is weaker
The vibrations inhibit vitamin K binding for the coagulation cascade
There is less atrial kick leading to blood being left behind in the atria to form a clot
Find the true statement:
Multifocal premature ventricular contractions look the same as bigeminy and come from the same spot
Ventricular premature contractions always require treatment
Patients with a ventricular premature contraction may have a pause in pulse followed by a strong beat or may complain of palpitations or skipped beats
Ventricular premature contractions more than 6 per minute or more than 3 in a row are no cause for concern
A patient in the hospital complains of heart palpitations, dyspnea, dizziness, and appears anxious and is sweating. This patient is experiencing:
Ventricular premature contraction
asystole
What is the correct order of progression?
Ventricular premature contraction (> 3 in a row), ventricular fibrillation, asystole, ventricular tachycardia
Ventricular tachycardia, quadrigeminy, ventricular fibrillation, asystole
Bigeminy, ventricular fibrillation, ventricular tachycardia, asystole
Ventricular premature contraction (> 3 in a row), ventricular tachycardia, ventricular fibrillation, asystole
Fixed P-R interval with a dropped QRS every third beat, may drop several QRS waves in a row, typically fixed with a pacemaker. Identify the arrhythmia:
1st degree AV block
2nd degree AV block type 2
2nd degree AV block type 1
Sinus block (aka “skipped beat”)
ECG presents as regular P and QRS waves that appear out of sync with each other. s/s include slow HR (< 60 bpm), drop in CO, and possible ventricular fibrillation. What arrhythmia may proceed this type of block?
Left bundle branch block
You are seeing a 65 y/o male. Upon reading the ECG you notice he has a widened Q wave and an elevated ST wave on leads V1 and V2. What do you do?
Ask the patient if he has had any ischemic heart attacks recently
Do not perform treatment and reschedule for another day
Do nothing and treat him like any other patient
Verify with nursing or the doctor to see if they are aware that this patient has had an MI
