An interactive representation of electrostimulation electrodes or vectors can be provided, such as for configuring combinations of electrostimulation electrodes. In an example, electrodes or test parameters can be presented graphically or in a table. A user interface can be configured to receive user-input designating electrode combinations or vectors for test or for use in programming an implantable or ambulatory medical device. The interface can be used to indicate suggested electrode combinations or vectors in response to a first selection of an electrode. Tests can be performed on electrode combinations and vectors, and the results of the tests can be presented to a user using the interactive representation. In an example, test results can be analyzed by a processor and optionally used to program an implantable or ambulatory medical device.

User interface system for use with multipolar pacing leads

Various techniques are disclosed for quickly and efficiently determining cardiac pacing vectors that minimize phrenic nerve stimulation.

System and method for selection of pacing vectors

A system or apparatus can provide electrostimulations via an electrode configuration that can be selected from multiple electrode configurations, the electrostimulations of the type for inducing a desired heart contraction, or a neurostimulation response. The system or apparatus can allow communicating with an external device to receive an input indicating a degree of patient discomfort with an electrostimulation delivered using a first electrode configuration, and can associate information about the degree of discomfort with information about the corresponding first electrode configuration for use by a controller circuit in determining a second electrode configuration for delivering a subsequent electrostimulation.

Automatic pacing configuration switcher

An apparatus comprises a cardiac signal sensing circuit, a pacing therapy circuit, and a controller circuit. The controller circuit includes a safety margin calculation circuit. The controller circuit initiates delivery of pacing stimulation energy to the heart using a first energy level, changes the energy level by at least one of: a) increasing the energy from the first energy level until detecting that the pacing stimulation energy induces stable capture, or b) reducing the energy from the first energy level until detecting that the stimulation energy fails to induce capture, and continues changing the stimulation energy level until confirming stable capture or the failure of capture. The safety margin calculation circuit calculates a safety margin of pacing stimulation energy using at least one of a determined stability of a parameter associated with evoked response and a determined range of energy levels corresponding to stable capture or intermittent failure of capture.

Method and apparatus for pacing safety margin

Noncaptured atrial paces can result in long-short cardiac cycles which are proarrhythmic for ventricular tachyarrhythmia. Approaches are described which are directed to avoiding proarrhythmic long-short cycles. For cardiac cycles in which the atrial pace captures the atrium, a first post ventricular refractory period (PVARP) and a first A-A interval are used. For cardiac cycles in which the atrial pace does not capture the atrium, both an extended PVARP and an extended A-A interval are used. The A-A interval following a noncaptured atrial pace is extended from an atrial depolarization sensed during the extended PVARP.

Methods and systems for mitigating the occurrence of arrhythmia during atrial pacing

An implantable cardioverter defibrillator (ICD) has a programmable ICD energy level corresponding to the maximum defibrillation energy deliverable with each defibrillation shock pulse. The ICD energy level is programmable within the maximum energy capacity of the defibrillation capacitor(s) of the ICD. In various embodiments, after a user enters the ICD energy level, one or more corresponding ICD performance parameters are presented. Restrictions are applied to the energy level programming of the ICD to ensure the predictability of the one or more ICD performance parameters.
