Discussion The ECG shows loss of atrial capture with preservation of ventricular pacing. The very wide paced QRS complex is highly suggestive of hyperkalemia even in a … WebOn the ECG, failure to capture is identified by the presence of pacing spikes without associated myocardial depolarization. Causes include pacing lead problems, battery or component failure, low pacing voltage or elevated myocardial pacing thresholds, and …

Web26 de nov. de 2024 · Atrial lead testing did not result in ventricular loss of capture and the RV pacing threshold was confirmed to be stably elevated at 2.875 V @ 0.4 ms with unchanged impedance. Given these findings, the existing leads were left in place and a generator change alone was performed. WebThe device ensures that false events do not influence the determination of capture and loss-of-capture during the search by aborting the search immediately when the … red hands the two
