Default Cardiac output - do "spikes" of increased HR to ~180 hurt?

In this thread http://www.8weeksout.com/phpBB3/viewtopic.php?f=3&t=271 Joel Jamieson states that "the stimulus for eccentric output is not cumulative, meaning it doesn't add up from session to session", i.e. 1 hour of cardiac output training (heartrate of 130-150bpm) is better than 2 30-minute sessions on different days.

I have a question about a similar but different scenario: in a 1+ hour CO workout, would 3 shorts bursts of intervals that spike my heartrate to ~180 for 2 minutes each every 20 minutes have a "dampening" effect on stimulating eccentric cardiac hypertrophy compared to just 1 hour of uninterrupted CO assuming the total time spent in the first scenario was increased so that the total time spent in the CO heartrate zone (130-150bpm) still added up to 1 hour?

If so, just how detrimental would it be (small or massive reduction in effectiveness of stimulating eccentric hypertrophy)?
