Question 20 · LEK · Automaticity and conduction disorders
Temporary cardiac pacing should be considered in the case of:
1) symptomatic bradycardia refractory to anticholinergic agents;
2) bradycardia in Wolff-Parkinson-White syndrome;
3) symptomatic second-degree atrioventricular block of type 2;
4) symptomatic second-degree atrioventricular block of type 1;
5) asystole with the P wave present on the ECG;
6) third-degree atrioventricular block.
The correct answer is:
2) bradycardia in Wolff-Parkinson-White syndrome;
3) symptomatic second-degree atrioventricular block of type 2;
4) symptomatic second-degree atrioventricular block of type 1;
5) asystole with the P wave present on the ECG;
6) third-degree atrioventricular block.
The correct answer is:
- A. all the above.
- B. 1,3,4,6.
- C. 1,3,5,6.
- D. 1,2,3,6.
- E. 3,4,5,6.
Hint
Pacing helps bradycardias at risk of asystole or with conduction failure below the AV node; think which listed situations fit.
