An information processing device communicates with a block set assembled by a user, and thereby obtains information on the structure of the block set. In addition, a corresponding position setting screen including an image of an object corresponding to the block set is displayed on a display device. The user moves a joint of the block set which joint is desired to be associated, by for example bending and stretching the joint. Next, the user indicates a joint to be associated on a 3D object side in the image of the 3D object by a cursor, and performs a determination input. The joint of the block set and the joint of the 3D object are thereby associated with each other. The block set and the object are interlocked with each other bidirectionally by thus setting the corresponding positions of the block set and the object.

A method of detecting atrial fibrillation includes detecting a pulse signal to obtain a time pulse waveform and converting it to an energy spectrum waveform via Fast Fourier Transform. The energy spectrum waveform includes a first frequency region, a second frequency region, and a third frequency region. The number of spikes in each frequency region was calculated and the heart indexes of the first, second, and third frequency regions were obtained, which were the first heart index, the second heart index, and the third heart index. And by the sum of the three heart index values and the first heart index to determine the possibility of atrial fibrillation. An apparatus for detecting atrial fibrillation is also provided, whereby the user can determine the possibility and predicting atrial fibrillation by simple measurement of blood pressure at home.

Automated pre-implant screening for candidate recipients of implantable medical devices. A set of cutaneous electrodes placed on a patient transcutaneously capture a cardiac signal using a screening device coupled to the electrodes. A first beat rate may be determined by identifying individual R-waves, QRS complexes or cardiac cycles from the captured cardiac signal using the cutaneous electrodes. A second beat rate may be calculated using one of several different methods, for example, by optical measurement, by monitoring heart sounds, by a second electric cardiac signal analysis, or by using an implanted device. The rates are compared to one another and, if a match is identified, the patient is deemed well suited to receive a particular device.
