After delivering a shock to cardiovert a 45 year old with supraventricular you look at the monitor and see the following rhythm. What should your next intervention be?
a. Place the defibrillator in the synch mode and deliver a shock at a higher joule setting
b. Deliver an unsynchronized 2nd shock at a higher joule setting
c. Have the patient perform vagal maneuvers and deliver another shock
d. Administer a dose of adenosine 6 mg IV rapidly
1. a. Supraventricular tachycardia. The rhythm is regular with a rate of 167 bpm. No P waves are seen. The QRS complexes are narrow. No ectopic beats are seen. PR: ---, QRS: .08 sec. QT: .28 sec.
2. a. Sinus rhythm with bigeminal PACs. The rhythm is irregular. The rate is around 70 bpm. Up right P waves are present and are paired with a QRS complex. The QRS complexes are narrow. PACs are seen every other beat. The ectopic P waves can be seen on the later portion of the T wave
3. c. Sinus rhythm with unifocal PVCs. The rhythm is irregular due to the PVCs. The underlying rate is 88 bpm. There are P waves with a positive axis that are paired with a QRS complex. Unifocal PVCs are seen every fourth beat, quadrigeminy. PR: .16 sec, QRS: .10 sec, QT: .36 sec.
4. a. Place the defibrillator in the synch mode and deliver a shock at a higher joule setting.
