The invention provides a premature ventricular contraction identification method and system. The method includes the steps that electrocardiogram signals are received; the electrocardiogram signals are preprocessed; the preprocessed electrocardiogram signals are classified through several classification models to obtain several original probability values; fusion decision-making is conducted on the original probability values based on a preset fusion decision-making rule to obtain a comprehensive probability value after fusion decision-making, and whether the preprocessed electrocardiogram signals are electrocardiogram signals indicating premature ventricular contraction or to-be-determined electrocardiogram signals indicating premature ventricular contraction is identified according to the comprehensive probability value; if the preprocessed electrocardiogram signals are to-be-determined electrocardiogram signals indicating premature ventricular contraction, extraction is conducted, and identification is conducted again according to the characteristic parameters of the preprocessed electrocardiogram signals. By means of the premature ventricular contraction identification method and system, higher PVC identification sensitivity, better PVC identification performance and higher PVC identification accuracy can be achieved.

An active implantable medical device, such as a pacemaker, defibrillator and/or cardiovertor having an AAI and/or an AAI/DDD operating mode. This device detects atrial and ventricular events and stimulates the atrium, and calculates an atrial escape interval (AEI). The device defines a critical period preceding or following the end of the AEI and determines, in the event of detection of a ventricular extrasystole (VES), if the moment of occurrence of the VES is in the critical period. The device then recognizes a risk of inappropriate operation and/or false diagnosis related to the temporal proximity of the VES and end of the AEI. In such a case, the device modifies an operating parameter so as to eliminate this risk, for example, by resetting the counting of AEI (AEI*) on detection of the VES. The device can also inhibit a switching of AAI mode to a DDD mode in the event of risk of false diagnosis of atrio-ventricular block.

The invention relates to an identification method for the premature beat in a dynamic electrocardiogram. The method comprises the following steps that 1) according to the detected position of the heartbeat, an inputFeature is extracted; 2) inputFeatures of the sinus heartbeat, the supraventricular premature beat heartbeat and the ventricular premature beat heartbeat are extracted from an electrocardiosignal database labelled with the known heartbeat type and merged into training data; 3) corresponding inputFeatures are extracted from all heartbeats of the dynamic electrocardiogram to be analyzed and merged into test Data; 4) a supervised learning algorithm is adopted for pre-classifying the test Data, the corresponding heartbeat types are output, and position information of the sinus heartbeat is extracted; 5) a certain number of pre-classified sinus heartbeats are selected and averaged, and a template of a sinus QRS composite wave is obtained; 6) by adopting an expert system based onsimilarity measurement, ECG forms and RR intervals, the supraventricular premature beat and the ventricular premature beat are judged. The method is suitable for identification of the ventricular premature beat and the supraventricular premature beat of long-time electrocardiogram data of the dynamic electrocardiogram and effectively assists doctors in making related diagnosis quickly.

The invention relates to a preparation method for traditional Chinese medicine alkaloid salt and application thereof, in particular to a preparation method for fumitory total alkaloids salt and application of the total alkaloids salt as a medicament for treating cardiovascular diseases. The method solves the problem of poor effect of treating the cardiovascular diseases due to poor water solubility and low bioavailability of the fumitory total alkaloids salt. The preparation method for the fumitory total alkaloids salt comprises the following steps: extracting and purifying fumitory coarse powder to obtain the fumitory total alkaloids, and then carrying out salt-forming reaction between the fumitory total alkaloids and acid to obtain the fumitory total alkaloids salt. The extraction ratio of the fumitory total alkaloids is more than 0.5 percent, and the purity of the obtained fumitory total alkaloids salt is more than 50 percent. The fumitory total alkaloids salt has the advantages that the fumitory total alkaloids salt has good water solubility, has a solubleness more than 60 percent, has high bioavailability, and is used as an effective component for treating the cardiovascular diseases, such as coronary heart disease, angina pectoris, arrhythmia and premature beat.

The invention discloses a non-invasive cardiac potential reconstruction method based on low-rank and sparse constraints and non-local total variation. Based on low-rank sparse decomposition and non-local total variation constraints, the endocardial and epicardial extracellular potentials are reconstructed. Based on the sparse nature of the cardiac surface potential, the sparse and low-rank constraints are applied to the potential, at the same time, the low-rank part of the potential is observed, many similarities in space and time can be seen, so that the non-local total variation constraint is applied to the low-rank part for restricting the non-local similarity of the heat surface potential, and finally the potential distribution of the endocardium and epicardium on the cardiac surface is reconstructed. The method has very important significance for arrhythmia diagnoses such as the determination of the ventricular premature beat position and time, and the determination of the myocardial position location and boundary.
