Oct 24, 2024 · If the patient’s native heart rate is above the pacemaker threshold, no pacemaker activity is expected and therefore output failure and capture failure cannot be recognised on the ECG.

Nov 10, 2022 · This article is a guide for interpreting abnormal Pacemaker - Failure to Capture EKGs, including qualifying criteria and a sample EKG rhythnm strip. Pacemaker failure to capture occurs …

Failure to capture: The pacemaker delivers a pacing spike, but it’s not followed by a QRS complex. This could be due to lead displacement, battery depletion, or an increase in the heart’s pacing threshold.

Failure to capture occurs when delivery of a pacing stimulus does not lead to myocardial depolarization. This can be caused by mechanical lead displacement or fracture, electrolyte abnormalities, and …

Mar 17, 2025 · In disorders of sensing, the pacemaker does not correctly recognize cardiac stimuli, either by excess or by default. Improper programming, alterations of the circuit, displacement or …

Feb 18, 2025 · Depending on your cardiovascular issues and health situation, they may be expected, but they could mean that your pacemaker is malfunctioning. Let us look at the signs of a possible …

Jun 30, 2015 · Failure to capture means either you are using too little current, or your lead is in a stupid position (i.e. not anywhere near the ventricular wall). The latter you can do nothing about. The former …

Failure to capture is when the pacemaker signal fires but there is no response. This is identified by having pacing spikes present with no resulting QRS, (capture).

Complete review on evaluation of pacemaker function, malfunction, ECG interpretation and management.

Mar 3, 2020 · Over-sensing happens when the pacemaker detects an electrical signal which is not expected to be sensed. Over-sensing results in an inappropriate inhibition of the pacing stimulus …
