Zusammenfassung: | The floating atrial rings are prone to FF QRS sensing because the sensing poles are mounted on a single lead body oriented perpendicularly to the ventricles. [...]atrial ASC requires an increased UT of 75% and a longer latent period of 350 ms to correct for prolonged PR intervals. [...]of the use of the ASC, 3 atrial events were not sensed. SMART believed now that the ventricular rate was faster than the atrial rate. [...]the VT markers also increased the VT counter. |
