Hello!

I recently pip installed the latest wfdb version onto my system. I see that the results are drastically changing. Like, I had to calculate the number of patients having one particular column of data. With version 2.2.1, I was getting 341 for p00 file. But, with latest wfdb package, I'm getting just 272. I'm not sure what kind of a glitch this is. I reverted back to 2.2.1 to try out, once I got a reduced count of result in 3.0.1, and it worked fine.
