Premature heart beats come in two different types, premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or a skipped beat. Typically have no long term complications.
Process and device for the treatment of atrial arrhythmia
A process for preventing atrial premature contractions originating within a pulmonary vein from being conducted into the left atrium of a human heart. More specifically, an ablation lesion is formed which electrically isolates the located source of the atrial premature contraction in the pulmonary vein from connection with the left atrium and blocks passage of the atrial premature contraction originating from the located source. In one embodiment, the steps of the process include advancing a medical device into the left atrium of a human heart, introducing the advanced medical device into the pulmonary vein from the left atrium of a human heart, sensing electrical activity within the pulmonary vein using the introduced medical device, locating a source of the atrial premature contraction within the pulmonary vein using the sensed electrical activity, and forming an ablation lesion in tissue of the pulmonary vein at a location proximal from the located source of the atrial premature contraction within the pulmonary vein. Conductive media and various medical devices may be used with the process.

Active implantable device medical such as pacemaker, defibrillator and/or cardiovertor of the AAI or AAI/DDD type
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.
