sup] For this reason, the manufacturer Medtronic had developed atrial automatic capture measurement (ACM) with a specific algorithm of introducing premature atrial pacing
and sensing of atrial or ventricular responses according to the pacing modes to assess atrial threshold.
Effects of spironolactone on atrial structural remodelling in a canine model of atrial fibrillation produced by prolonged atrial pacing
Very seldom, rapid atrial pacing
may be needed to abolish atrial flutter.
Improved suppression of recurrent atrial fibrillation with dual-site right atrial pacing
and antiarrhythmic drug therapy.
The most interesting finding was that the programmer showed 99% atrial pacing
and less than 1% ventricular pacing (Fig.
The system is comprised of the Sonr hemodynamic sensor embedded in the Sonrtip atrial pacing
lead and the Paradym RF Sonr CRT D device, which includes an algorithm designed to automatically optimize the patient's atrioventricular delay and interventricular delay timing.
24 Other strategies, such as continuous overdrive atrial pacing
through temporary epicardial electrodes, is currently under investigation.
These were the two major findings of the large, international, randomized ASSERT (Asymptomatic Atrial Fibrillation and Stroke Evaluation in Pacemaker Patients and the Atrial Fibrillation Reduction Atrial Pacing
Dual A-V nodal pathways can be readily demonstrated in many patients by atrial pacing
techniques but have never been shown histologically.
In the presence of atrial pacing
leads, accurate diagnostic information can be obtained by obtaining a multi-lead atrial electrogram recording.
By gradually increasing the pacing current until stable capture of atrial pacing
was confirmed by surface ECG, the pacing threshold of all 9 electrode positions was found.
