Pacing induced electrical activation grading

Abstract

In one embodiment, a medical procedure system includes a probe for insertion into a chamber of a heart of a living subject, and including a first electrode to apply a sequence of pacing pulses at a position in the chamber, a second electrode to sense an electrical activation signal responsively to electrical activations induced by capture of the pacing pulses in a myocardium of the chamber, a display, and processing circuitry to evaluate a successful acquisition by the second electrode of the induced electrical activations responsively to the electrical activation signal, the successful acquisition being indicative of a successful capture of the pacing pulses by the myocardium, compute a capture grade responsively to the evaluation of the successful acquisition of the induced electrical activations, the capture grade being indicative of a count of the induced electrical activations evaluated as being successfully acquired, and render the capture grade to the display.
