Oxygen consumption, heart rate, and thermal tolerance were measured in week-old embryos of Heermann's gull ( h r u s heermanni). Heart rate and oxygen consumption are temperature independent between 30 and 40 C and average 120 beats/min and 1.87 cm3 Ot/(egg-h). Below 30 C, these rate processes become strongly temperature dependent, and the heart stops beating when cooled to 7-13 C. The beat rec...

Osteopathic manipulative medicine researchers often use sham therapy as the placebo control during clinical trials. Optimally, the sham therapy should be a hands-on procedure that is perceptually indistinguishable from osteopathic manipulative treatment, does not create an effect on its own, and is not a treatment intervention. However, the sham therapy itself may often influence the outcome. T...

In this chapter, a new concept learning-based approach is presented for abnormal ECG beat detection to facilitate long-term monitoring of heart patients. The novelty in our approach is the use of complementary concept – “normal” for the learning task. The concept “normal” can be learned by a ν-Support Vector Classifier (ν-SVC) using only normal ECG beats from a specific patient to relieve the d...

Background: Left ventricular (LV) systolic function during atrial fibrillation (AF) is positively correlated with an index of ventricular cycle-length irregularity, the ratio of preceding R-R interval to pre-preceding R-R interval (RRp/RRpp). This study was designed to elucidate the relationship between the RRp/RRpp ratio and LV function, and to identify factors which influence the relationship...

An apparatus is described which permits the simultaneous recording of body temperature and heart beat frequency in young mice. When heart beat frequency is related to body temperature the values of the temperature characteristic for the inbred albino strain used are 22,400- calories over the range 15 to 20 degrees +, 16,000+/- calories from 20+ to 27 degrees , and 11,000+/- calories from 27 to ...

Ventricular tachycardia or fibrillation (VT) as fatal cardiac arrhythmias are the main factors triggering sudden cardiac death. The objective of this recurrence quantification analysis approach is to find early signs of sustained VT in patients with an implanted cardioverter-defibrillator (ICD). These devices are able to safeguard patients by returning their hearts to a normal rhythm via strong...
