Embodiment Construction

[0027] The specific implementation of the present invention will be described below with reference to the accompanying drawings. The present invention will use ICD as an example to illustrate the medical equipment for judging T wave oversensing by using a blood flow sensor. It only understands the preferred technical scheme that the present invention is made by those skilled in the art, and does not limit the protection scope of the present invention, and obviously the technical scheme of the present invention can also be applied to implanting a cardiac pacemaker, or a dynamic electrocardiogram recorder ( Holter) or an implanted cardiac monitor.

[0028] figure 1 It shows a schematic diagram of the position of the implantable medical defibrillator implanted in the human body B. For the sake of simplicity, the physiological structures of the human body irrelevant to the present invention are omitted, and the connection relationship between the ICD100 and the heart h through wir...

Abstract

An implanted medical device utilizing blood flow sensor to detect T wave over-perception. The implanted medical device comprises an ECG signal sensing wire and a blood flow sensor integrated on the wire, and the wire enters the ventricle through the coronary vein to keep the blood flow sensor in the ventricle; the implantable medical device also comprises a functional circuit, and the functional circuit is electrically connected with the wire to receive the ECG signal and the intraventricular blood flow signal sensed by the blood flow sensor; the functional circuit comprises a control module,and the control module is configured to judge whether T wave over-perception is occurs according to the intraventricular blood flow signal; and the detection of T wave over-perception by utilizing theblood flow sensor has higher accuracy than the detection relying on the electrical signals.

Description

technical field [0001] The invention belongs to the field of cardiac implantable medical equipment, and in particular relates to improving heart rate perception by utilizing blood flow in a patient's heart. Background technique [0002] For cardiac implantable medical devices, T-wave over-perception causes false perception of the patient's heart rate. For a variety of reasons, implantable cardiac medical devices are set with a high perception sensitivity, so the device may recognize the T wave of the patient's heart as an R wave due to the high perception sensitivity, resulting in device perception The heart rate is twice the actual heart rate of the patient. Taking the implantable cardiac monitoring device ICM as an example, the perception algorithm and diagnosis algorithm of the ICM are based on the heart rate. If the T wave exceeds the perception, it may cause ICM misdiagnosis and cause its wrong early warning, especially the possible Can lead to misdiagnosis of atrial ...
