20 to 40
Your patient has a regular bradycardic rhythm with a rate of 40, no P waves, and a QRS greater
than 0.12. This is:
Ventricular escape rhythm
Absolute bradycardia means that:
The heart rate is less than 60 beats per minute
Which of the following may be a lethal treatment for a patient with a ventricular escape rhythm?
Lidocaine
You are treating a patient who is complaining that his heart is "skipping beats." On ECG
evaluation, you see frequent PVCs that are occurring in groups. The patient's blood pressure is
100 systolic. Treatment for this patient:
Should include oxygen and lidocaine
The treatment of choice for a symptomatic ventricular escape rhythm is:
Pacing
Which of the following is true of ventricular tachycardia?
Ventricular tachycardia is triggered by a PVC
Patients with pulseless ventricular tachycardia should be treated as though they have:
Ventricular fibrillation
Synchronized cardioversion is acceptable for patients with ventricular tachycardia:
In all cases
The most common arrhythmia in sudden cardiac arrest is:
Ventricular fibrillation
Defibrillation of patients in asystole:
Is not recommended
Which of the following is an absolute indication for unsynchronized cardioversion?
Ventricular fibrillation
Demand pacemakers fire:
When the patient's rate drops below a preset number
You are treating a 65-year-old man who is complaining of chest pain and difficulty breathing. On
ECG examination, you note that his ventricular heart rate is 56, and there are more P waves than
QRS complexes. The PR interval is constant when a QRS follows a P wave. The QRS complexes
are normal and narrow.You suspect this patient has what type of heart block?
Second-degree type II
You are treating a 65-year-old man who is complaining of chest pain and difficulty breathing. On
ECG examination, you note that his ventricular heart rate is 56, and there are more P waves than
QRS complexes. The PR interval is constant when a QRS follows a P wave. The QRS complexes
are normal and narrow. This type of heart block is typically considered to be a:
Serious arrhythmia regardless of signs and symptoms
You are treating a 65-year-old man who is complaining of chest pain and difficulty breathing. On
ECG examination, you note that his ventricular heart rate is 56, and there are more P waves than
QRS complexes. The PR interval is constant when a QRS follows a P wave. The QRS complexes
are normal and narrow. The definitive treatment for this patient is:
Transvenous pacemaker insertion
You are treating a 65-year-old man who is complaining of chest pain and difficulty breathing. On
ECG examination, you note that his ventricular heart rate is 56, and there are more P waves than
QRS complexes. The PR interval is constant when a QRS follows a P wave. The QRS complexes
are normal and narrow. Prehospital care for this patient consists of:
Transcutaneous pacing
You are treating a 65-year-old man who is complaining of chest pain and difficulty breathing. On
ECG examination, you note that his ventricular heart rate is 56, and there are more P waves than
QRS complexes. The PR interval is constant when a QRS follows a P wave. The QRS complexes
