atrial-His (AH), and His-ventricular (HV) intervals of 1012, 68, and 51 ms, respectively. During atrial overdrive pacing at a cycle length of 420 ms, the following EKG was recorded (Fig.

All patients underwent sequential TWA testing using atrial and ventricular pacing. Results: During atrial pacing requiring physiologic conduction to the ventricles, 21% of TWA tests were positive ...

Objective: Evaluation of the capability of the Oesophageal Doppler Monitor to detect slight changes in cardiac output as they occur during desynchronizing ventricular pacing (VVI) in children ...

The abstract, titled “Artificial Intelligence ECG Analysis More Accurately Identifies Epicardial versus Endocardial Ventricular Tachycardia and Pacing Compared with Visual Criteria,” presents ...

although intermittently effective ventricular stimulation by the pacemaker was apparent on 12-lead ECG. The VVIR pacemaker had been implanted 8 years earlier to treat bradyarrhythmia in the ...

where she had undergone the placement of a dual-chamber pacemaker to treat sick sinus syndrome. An ECG on admission revealed atrial fibrillation with ventricularly stimulated ventricular complexes ...
