A device for detection and treatment of tachycardias, which is able to selectively identify the occurrence of re-entrant AV nodal tachycardia, and to distinguish it from sinus tachycardias. The apparatus monitors the occurrence of atrial and ventricular depolarizations during a detected tachycardia, and, in the event that a series of ventricular depolarizations occur which are each closely preceded or closely followed by an atrial depolarization, at an interval substantially less than would be expected in the case of a sinus tachycardia, re-entrant AV nodal tachycardia is identified, and an appropriate therapy regimen is triggered. |
