WebCircadian rhythms, core body temperature, metabolism, hormones and intrinsic rhythms generated by the heart all contribute to lower-frequency rhythms (e.g., very-low-frequency and ultra-low-frequency rhythms) that extend below 0.04 hertz. In healthy individuals, there is an increase in VLF power that occurs during the night and peaks before waking. WebJul 11, 2014 · Jose and Collison (1970) defined “intrinsic heart rate (IHR)”, as the heart rate under the simultaneous presence of the nonselective β-adrenoceptor antagonist propranolol (0.2 mg/kg) and the muscarinic receptor blocker atropine (0.04 mg/kg) 5 min after these injections, and this definition continues to be used in mainstream cardiology literature.
