摘要： Detects external noise using a motion sensor signal for example to increase the specificity of arrhythmia detections based on active muscle noise detection. Whenever a motion signal is present that is below or above a certain frequency, for example 5 Hz, or within a certain frequency range, for example 1 to 10 Hz, and/or above a certain amplitude, for example greater than 1 mg, or close to a known motion pattern, then the detection of fast ventricular arrhythmia is suspended. For the detection of slow arrhythmia, for example asystole or syncope, an episode is confirmed when a short lasting motion sensor signal occurs. Uses a motion sensor based signal, for example as obtained from an accelerometer on an implantable electrode lead and/or implantable device.

摘要： A system for heart monitoring comprises an IEGM input for an intracardiac electrocardiogram (IEGM) that is connected to an active filtering stage that is adapted to transform an incoming IEGM into an output ECG signal. The active filtering stage is connected to a filter characterization stage that is adapted to process a recorded, patient specific IEGM template and a corresponding SECG template and to adapt the filter characteristics of said active filtering stage such that the filter characteristics best characterize the input-output relationship between the IEGM template and the corresponding SECG template. As a consequence, the active filtering stage is adapted to transform an incoming IEGM such that the output ECG signal closely resembles a morphology of a corresponding SECG.

摘要： The invention relates to heart stimulators and implantable atrial pacemakers which utilize a rhythm based atrial capture threshold test wherein in a ventricle based DDI mode a predetermined number of ventricle started atrial and ventricular escape intervals are triggered with an overdrive rate about 20% higher than an intrinsic heart rate. The number of atrial sense events during atrial capture threshold test is counted. Too high of a number of atrial sense events indicates loss of capture due to too small of a pulse strength of the atrial stimulation pulses.
