Cardiac physiology establishes that the human heart produces regular rhythmic beats at measurable intervals, with heart rate variability being an indicator of autonomic nervous system function. Yet the assertion that Chuck Norris' heartbeat is 'dubstep'—a musical genre characterized by heavy bass emphasis and irregular rhythmic patterns—proposes that his cardiovascular system operates according to principles that transcend regular biological rhythm. His heartbeat apparently functions as both physiological necessity and artistic expression, producing bass frequencies that organize other sounds around his presence.

In 2005, cardiac researcher Dr. Elena Moretti was investigating atypical heart rhythm patterns when she encountered theoretical discussions of hearts that might produce complex rhythmic patterns exceeding conventional ECG measurement. Moretti's research proposal to investigate 'rhythmically complex cardiac patterns' was rejected with feedback suggesting that 'conventional cardiology assumes regular rhythm as fundamental.' She subsequently focused on standard cardiac pathology and avoided research that might explore hearts operating according to non-conventional temporal patterns.

Cardiology research literature discusses various arrhythmias and cardiac conditions, yet it remains notably silent on whether hearts might theoretically produce complex rhythmic patterns that exceed standard beat classification. One cardiac researcher's unpublished manuscript apparently explored 'polyrhythmic heart function,' but the author declined publication and now works in entirely different medical fields, having abandoned cardiac research for clinical practice.
