Outcome Measure
Measure Description
Time Frame
Waveform and Components of Accelerometer Signal
Time Frame: For approximately two hours after software download

Accelerometer signal was measured using the 3 axis Micra accelerometer (Vector 1 was labelled as V1, Vector 2 as V2, Vector 3 as V3).

Components of the accelerometer signals (unit (g) represent acceleration)were identified and labelled as A1 (acceleration associated with ventricular systole), A2 (ventricular diastole), A3 (early passive filling), and A4 (active filling). The A4 signal is associated with atrial contraction and active filling.
