@jc76 I have a Metronic ICD. The data is downloaded to the cardiologist office from the collector box on the bedroom shelf and it can be studied . The test result is posted to My Chart. The electrophysiologist looks at all the numbers and graphs. He'll summarize the findings in a sentence, but I do understand a couple of the graphs. I drink 2 quarts/liters each day, the HCM affected my kidneys which I need to keep flushed.
