摘要:
Methods and systems are directed to detecting atrial tachyarrhythmia. A plurality of A-A intervals is detected. The detected A-A intervals are selected and used to detect atrial tachyarrhythmia. Selecting A-A intervals may be based on determining that A-A intervals are qualified. Qualified A-A intervals may be determined if a duration of the particular A-A interval falls outside a predetermined duration range, for example. Qualified A-A intervals may also be determined based on events occurring between consecutively sensed atrial events of the particular A-A interval, and whether the duration of the particular A-A interval falls within the predetermined duration range, for example.
摘要:
A method and system for generating a characterization of one beat of a patient's supraventricular rhythm (SVR) involves performing such characterization while the heart is being paced. During SVR characterization, various pacing parameters are modified and the patient's supraventricular rhythm is characterized while the pacing parameters are modified. The SVR characterization process is effective in single and multiple chamber pacing modes.

摘要:
An implantable atrial defibrillator applies cardioverting electrical energy to the atria of a human heart in need of cardioversion after first determining if there is an absence of potential atrial fibrillation. A sensor associated with the atria of the heart senses activity of the heart and generates a cardiac signal and a first detector detects cardiac events from the cardiac signal. A second detector responsive to time spans between immediately successive detected cardiac events which are grater in duration than a preselected interval detects for an absence of potential atrial fibrillation. An atrial fibrillation detector detects for atrial fibrillation if the second detector fails to detect an absence of atrial fibrillation, and a cardiovertor applies cardioverting electrical energy to the atria when the atria are in fibrillation.

A method of fabricating a semiconductor device is provided. An etch-target layer is formed on a substrate. A photoresist layer is formed on the etch-target layer. A first exposure process is performed using a first photo mask to form a plurality of first-irradiated patterns in the photoresist layer. The first photo mask includes a plurality of first transmission regions. Each first transmission region has different optical transmittance. A second exposure process is performed using a second photo mask to form a plurality of second-irradiated patterns in the photoresist layer. The second photo mask includes a plurality of second transmission regions. Each second transmission region has different optical transmittance. A photoresist pattern is formed from the photoresist layer by removing the plurality of first-irradiated and second-irradiated patterns from the photoresist layer. A lower structure is formed from the etch-target layer by etching the etch-target layer using the photoresist pattern.
