The heart rate story

One Mother's Heart Story.

The story of the gouty heart.

Many distinguished fellows of the College of Physicians including Harvey suffered from gout in the past, as recorded in Munk's Roll (I878-I968). As an example may be cited Dr. William Stukeley (I687 -I765) who started practice in Boston, my native town. He had long been a sufferer from gout and overpowered by repeated attacks he turned his thoughts to the Church, was ordained in I729, and becam...

The pacemaker story: a cold heart spinoff.

It is 1949. Room 64 in the hasement of the Banting Institute in Toronto was the home of the fledgling cardiovascular surgical lahoratory. Experiments on the microcirculation and on hypothermia were initiated as two different projects. We were astonished to find as work progressed, that they were closely interrelated: Cooling an animal helow a certain body temperature level produced serious obst...

Heart Rate and Respiratory Rate Influence on Heart Rate Variability Repeatability: Effects of the Correction for the Prevailing Heart Rate

BACKGROUND Since heart rate variability (HRV) is associated with average heart rate (HR) and respiratory rate (RespRate), alterations in these parameters may impose changes in HRV. Hence the repeatability of HRV measurements may be affected by differences in HR and RespRate. The study aimed to evaluate HRV repeatability and its association with changes in HR and RespRate. METHODS Forty health...

Amygdala and heart rate variability responses from listening to emotionally intense parts of a story

Emotions are often understood in relation to conditioned responses. Narrative emotions, however, cannot be reduced to a simple associative relationship between emotion words and their experienced counterparts. Intensity in stories may arise without any overt emotion depicting words and vice versa. In this fMRI study we investigated BOLD responses to naturally fluctuating emotions evoked by list...
