ECG Lead II measurement notes

Now I am using the ATTEN ADS1102CAL+ (100MHz, 1G sample, 7 inch wide screen, RMB1,850 2013jun) to measure the Lead II voltage.

By  a couple of trials and errors, I seemed to have captured my own heart signal at the following setting.

Ch 1, Ch 2, 50 mV,

M 10 uS.

I need to check the timing to make sure if what I am seeing is indeed the P, QRS, and T wave.

Very roughly, R wave is 100 mV, and P,QRS, and T total time is 50 uS.  So I need to google again.
