  • Long-term monitoring for detection of atrial fibrillation
    Publication number: 20060084883
    Abstract: A method and a system for detection of an arrhythmia, the method comprising determining a number of heart beat intervals; determining an instantaneous heart rate for each of the heart beat intervals; determining the variability of the instantaneous heart rates compared to a mean of the number of instantaneous heart rates; determining a non-linear value that represents the variability of the instantaneous heart rates; and detecting the arrhythmia by comparing the non-linear value with a predetermined threshold.

  • Laser catheter delivery system for controlled atheroma ablation combining laser angioplasty and intra-arterial ultrasonic imagining
    Patent number: 4887605
    Abstract: Laser catheter delivery system for controlled ablation of atheroma, combining laser angioplasty and intra-arterial ultrasonic imaging. In laser ablation of atheroma, dosage and directing of the laser light beam represent critical problems, since accurate removal of the atheroma is required without damaging of the arterial wall.
