Sinus node responses to perfusion pressure changes, ischaemia and hypothermia were evaluated in 22 isolated blood-perfused dog atria. Sinus cycle length (SCL) was measured and sinoatrial conduction time (SACT) was estimated using the premature atrial stimulation technique (PAS) and the constant atrial pacing method (CAP). There was a good correlation between the results obtained with both techniques (r = 0.8297) but CAP had less depressing action on sinus node automaticity. Increasing the… 
Moderate Hypothermia Depresses Arterial Baroreflex Control of Heart Rate during, and Delays Its Recovery after, General Anesthesia in Humans
It is indicated that moderate hypothermia enhances anesthesia-induced depression of baroreflex function in anesthetized humans and delays its recovery after general anesthesia.
Effect of hypothermia on baroreflex control of heart rate and renal sympathetic nerve activity in anaesthetized rats
Baroreflex control of RSNA and HR was similar between both groups of rats, which implied that the control was non‐adaptive on chronic cold exposure, which could contribute to hypothermic hypotension and may primarily reflect an effect of Tb on central drive.
Temperature regulates the arrhythmogenic activity of pulmonary vein cardiomyocytes.
It is demonstrated that PV cardiomyocytes have an increase in arrhythmogenic activity at high temperatures because of enhanced automaticity, induced triggered activity, or shortening of action potential duration.

Decrease in cardiac output and descending aorta blood flow, and preferential cerebral redistribution of cardiac output along with an increase in systemic peripheral vascular resistance may affect systemic organ perfusion and cerebral metabolism in newborns with hypoxic-ischemic encephalopathy.

It is not a crucial point whether adjustment for the heart rate during therapeutic hypothermia for PCAS should be done or not, but it should be considered to maintain the cerebral blood flow under the strict hemodynamic control during the early phase of this catastrophic state.

Secondary Increase of Lactate Levels in Asphyxiated Newborns during Hypothermia Treatment: Reflect of Suboptimal Hemodynamics (A Case Series and Review of the Literature)
Lactate levels during the first 4 days of life should be followed as a potential marker for suboptimal hemodynamic status in term asphyxiated newborns treated with hypothermia, for whom the maintenance of homeostasis during Hypothermia treatment is of utmost importance to alleviate brain injury.
