Title
(EN) DIAGNOSIS AND THERAPY OF BIGEMINY AND FREQUENT PREMATURE CONTRACTIONS
(FR) DIAGNOSTIC ET THÉRAPIE DU BIGÉMINISME ET DES CONTRACTIONS PRÉMATURÉES FRÉQUENTES
Abstract
(EN)
The disclosure describes techniques for diagnosing premature contractions of a patient's heart. This system may differentiate premature atrial contractions (PACs) and premature ventricular contractions (PVCs) from atrial fibrillation by identifying changes in R-wave intervals, i.e., R-R intervals, on a Lorenz plot, measuring a coupling interval between R-waves, and analyzing a morphology of the premature contractions, e.g., the QRS complex. These techniques may also identify when severe premature contractions, or bigeminy, are present. In response to the type of premature contractions detected, the system may alert a user of the premature contractions and/or deliver cardiac pacing at an increased pacing rate to eliminate the abnormal intrinsic contractions. The system may also adjust the pacing rate and pacing rate duration for persistent premature contractions.

La présente invention concerne des techniques de diagnostic des contractions fréquentes du cœur d'un patient. Ce système permet de différencier les contractions auriculaires prématurées (PAC) et les contractions ventriculaires prématurées (PVC) de la fibrillation auriculaire par identification des modifications des intervalles entre deux ondes R, en d'autres termes, des intervalles R-R, sur une courbe de Lorenz, en mesurant un intervalle de couplage entre deux ondes R, et en analysant une morphologie des contractions prématurées, par exemple, le complexe QRS. Ces techniques peuvent également permettre d'identifier le moment auquel se produisent des contractions prématurées graves, ou bigéminisme. En réponse au type de contractions prématurées détectées, le système peut alerter un utilisateur des contractions prématurées et/ou appliquer une stimulation cardiaque à une fréquence de stimulation accrue pour éliminer les contractions intrinsèques anormales. Le système peut également ajuster la fréquence de stimulation et la durée de la fréquence de stimulation en cas de contractions prématurées persistantes.
