How to extract numbers from a header line

Ok so I am trying to extract numbers from this header in a textfile that looks something along the lines of

Lead Number 1 Time Step .001 Data Points 6001
0
0
0
0
1.1
.34
ect.

This is my code so far:

filename = 'ecgnormal.txt';
delimiterIn = ' ';
headerlinesIn = 1
A = importdata(filename,delimiterIn,headerlinesIn);
data = (A.data);
header = A.textdata

Where data is all the data and header is now the top line of the file. How can I extract those numbers from the header line and assign them to variable?

>> A.header={'Lead Number 1 Time Step .001 Data Points 6001'};
>> fmt='Lead Number %f Time Step %f Data Points %f';
>> hdrVals=cell2mat(textscan(char(A.header),fmt,'collectoutput',1))
hdrVals =
 1.0e+03 *
  0.0010    0.0000    6.0010
