Filed:

Apr 2, 2009

Appl. No.:

12/935060

Inventors:

Alireza Ghodrati - North Andover MA, US

International Classification:

A61B 5/0452
A61N 1/39
A61N 1/365

US Classification:

600519, 607 5, 607 17

Abstract:

A system is provided which processes cardiac condition data representative of heart electrical signals to identify a cardiac condition. An acquisition processor is conditioned for acquiring data representing a sequence of successive pulses of a type of electrical heart waveform of a patient. A computation processor is electrically coupled to the acquisition processor and is conditioned for calculating a pulse interval irregularity measure based on a sum of time interval differences occurring between pairs of successive pulses of the sequence of successive pulses and excluding time interval differences exceeding a predetermined maximum threshold from the sum. The computation processor is further conditioned to compare a calculated pulse interval irregularity measure with a predetermined irregularity measure threshold. An output processor is electrically coupled to the computation processor and conditioned for generating data representing an alarm message in response to the calculated pulse interval irregularity measure exceeding the predetermined threshold.

Abstract:

A medical system including a catheter, a sheath, and a controller. The catheter having a catheter distal end that includes multiple electrodes, the sheath configured to receive the catheter and having a sheath distal end configured to cover one or more of the multiple electrodes, and the controller configured to supply a current between electrodes of the multiple electrodes and to measure voltages from at least two of the multiple electrodes to determine whether one or more of the multiple electrodes is covered by the sheath.
