Two quick points . . . :

At present, of the 175 patients who have disclosed pacing data via the web, 102 have exceeded three year life expectancy, more than 58%, whereas ordinarily less than 50% would be expected to do so. There are 67 cases who did not include their onset date.

At present, of 100 patients who have disclosed pacing data via the web, where their data is sufficiently complete, 45 have exceeded five years . . . 55 have not done so but of these 11 may still do so. The expected number of patients exceeding five years is about 20% . . . far less than 45%.
