Dear Science Maniac,
I am not aware of a human condition who have more or less than 4 chambers for their heart but in researching to find in answer to your question, I came across an interesting web page which states that ‘Mammals and birds have four-chambered hearts, but frogs have just three, with two atria and one ventricle’. there are other intersting facts in it which i thought you might be interested in reading. Link below.
