主　　题：algorithm pacemaker RYTHMIQ (R) ventricular pacing 

摘      要：An 80-year-old woman received a dual chamber pacemaker (Boston Scientific Accolade MRI DR) for pre-syncopal episodes associated with transient II-degree atrioventricular block type 1 and 2:1, recorded in 24-h Holter monitoring. Due to residual AV conduction with I-degree AV block, the pacemaker was set with the RYTHMIQ (R) algorithm, in order to reduce inappropriate ventricular pacing. A month later the patient started to complain of severe asthenia and bradycardia (46-48 bpm). Telemetry-supported pacemaker control revealed III-degree AV block with junctional escape rhythm, unmasking missed switch of RYTHMIQ (R) algorithm.
