Event Description
|
On (b)(6) 2015, on a follow-up performed on a patient with background of atrial fibrillation, all the measurements were normal.In order to promote the spontaneous rhythm, different atrio ventricular (av) intervals were programmed and the patient started to feel bad.When programming the av interval to 230/170 with a frequency of 50 min-1, according to the physician, when clicking on the "program" button, the programmer head was moved from the correct position and then telemetry was lost.At that moment the patient suffered a heart failure with loss of sphincter muscle control and a cardiac resuscitation was needed.The patient recovered especially when vvi mode at 80min-1 was programmed.Preliminary analysis showed that retrograde (va) conduction was observed within the follow-up.This may have been caused by the application of asynchronous modes during the tests performed within the follow-up and/or modifications of timing parameters (rates and/or avd) as reported and confirmed through files analysis.The retrograde conduction was not observed anymore at the end of the follow-up.
