Cardiac Pacing Failure To Capture Failure To Sense

Cardiac Pacing Failure To Capture Failure To Sense Cardiac Failure Complete review on evaluation of pacemaker function, malfunction, ecg interpretation and management. Pacing failure: this ecg shows a ventricular paced rhythm with intermittent failure to capture: atrial sensing appears to be intact — ventricular pacing spikes follow each p wave, most easily seen in v3 6 (tiny pacing spikes are also visible in i, avr and v1).

Pacing Failure Ecg Showing Intermittent Failure To Capture Arrow Oversensing occurs when pacemaker activity is inhibited by inappropriately recognized non cardiac activity (i.e., skeletal muscle). failure to sense occurs when the pacemaker fails to sense native cardiac activity which leads to asynchronous pacing. pacing spikes can be seen within qrs complexes. Ventricular pacing spikes are visible and not only fail to capture the myocardium but show evidence of undersensing: note the inappropriate pacing soon after a qrs complex, after the 3rd beat. Next, analyze the rhythm strip for failure to pace, failure to capture, and failure to sense. remember that the ecg will reveal an absence of pacemaker spikes at their programmed time with failure to pace. Failure to sense occurs when the pacemaker does not detect the patient's myocardial depolarization. this can often be seen on an ekg tracing as a spike following a qrs complex too early.

Sinus node dysfunction sinus bradycardia arrest, sinoatrial block, chronotropic incompetence, a fib. cardiac resynchronization therapy conduction delay (>150msec with mortality benefit) in chronic systolic heart failure further decreases ef, increases remodeling and increased mr. Periodic evaluation of an implanted pacemaker is required to maintain optimal programming, assess battery life, and identify and correct system malfunctions. the evaluation and management of common problems of single and dual chamber pacemaker systems will be reviewed here. The commonly encountered problems are failure to sense, failure to pace, and failure to capture. icds are much more complex devices and their malfunctions occur more often than in pacemakers. 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 sense: the pacemaker fails to detect your heart’s natural beats.
