CCT Cardiac Monitoring & Emergency Response 5

Question 1

During a rapid response event, the team identifies the rhythm as supraventricular tachycardia (SVT) with a rate of 170 bpm in a hemodynamically stable patient. The first-line pharmacologic treatment is:

Accepted Answer

Adenosine 6 mg rapid IV push

Answer

Adenosine 6 mg given as a rapid IV push followed by a saline flush is the first-line drug for terminating stable SVT by transiently blocking AV nodal conduction.

Question 2

Which of the following ECG findings is most suggestive of digoxin toxicity?

Accepted Answer

Sagging ST depression with a scooped appearance and slow ventricular rate

Answer

Digoxin produces a characteristic scooped or 'Salvador Dali mustache' ST depression along with bradyarrhythmias due to increased vagal tone.

Question 3

A CCT observes fusion beats and capture beats during a wide complex tachycardia. These findings are diagnostic of:

Accepted Answer

Ventricular tachycardia

Answer

Fusion beats (partial sinus and ventricular depolarization) and capture beats (brief sinus capture) are pathognomonic criteria for ventricular tachycardia per Brugada criteria.

Question 4

What is the correct pad placement for anteroposterior (AP) defibrillation?

Accepted Answer

One pad on the left anterior precordium and one pad on the posterior left thorax

Answer

AP placement positions one pad over the left precordium (cardiac apex area) and the second pad on the posterior left thorax directly behind the heart.

Question 5

A patient being monitored post-cardiac catheterization develops sudden onset of hypotension, distended neck veins, and muffled heart sounds. The ECG shows low voltage and sinus tachycardia. The technician should suspect:

Accepted Answer

Cardiac tamponade

Answer

Beck's triad (hypotension, JVD, muffled heart sounds) combined with low-voltage ECG after cardiac catheterization strongly suggests pericardial tamponade from procedural complication.
