Just remember the heart is a pump. It attempts to pump the demanded volume of fluid by using a combination of Speed (Heart Rate) and Pressure (Blood Pressure). A heathy heart will only pump the required volume of blood, no more and no less. It will vary the HR and BP in coordination to deliver that volume. An unhealthy pump whether by disease or poor maintenance will give skewed readings as it attempts to do its' job, but can't.

So, HR by itself doesn't mean a lot. Nor, does BP by itself. Factor in any electrical circuitry or mechanical problems from the birth process and numbers produced may mean even less.
