Question

identify rhythm.

v-paced
av paced (dual) working and sensing appropriately.
a- paced
av paced w/ failure to capture

Explanation:

Analyze pacemaker spikes on the ECG strip

Observe the presence of two distinct pacemaker spikes preceding each ventricular depolarization (QRS complex): one spike occurs before the P wave (atrial pacing) and a second spike occurs before the wide QRS complex (ventricular pacing).

Evaluate sensing and capture

Each atrial pacing spike is followed by a P wave, and each ventricular pacing spike is followed immediately by a wide QRS complex, demonstrating 100% electrical capture. There are no intrinsic beats or inappropriate spikes, indicating appropriate sensing and pacing functions.

Match with the correct option

The presence of both atrial and ventricular pacing spikes with appropriate capture and sensing corresponds to a dual-chamber paced rhythm (AV paced) working and sensing appropriately.

Answer:

• V-paced
• AV paced (dual) working and sensing appropriately. (Correct answer)
• A- paced
• AV paced w/ failure to capture
