Using short-term(5 minutes)time and frequency domain measures of HRV,standard deviation of heart rate in beats/min(HRSD),standard deviation of the mean of all 5 minutes segments of normal RR intervals(SDANN),percent of difference between adjacent normal RR intervals that was longer than or ...
In the short term after heart transplantation, in which the transplant is denervated by the surgery, the HR is higher than the normal physiological HR, which is 60 to 80 bpm [15]. For a longer period of time after transplantation, it changes back towards normal physiological HR, probably ...
However, the signal in the rejected Holter segments was heavily disturbed by interference from electric signals from other muscles or movement artefacts, which indicates that the underlying "true" heart beat pattern was a normal sinus rhythm with no more aberrant beats than normal. However, as raw...
the standard deviation of normal-to-normal (NN) intervals (SDNN) expresses the overall variability of heart rate. While the root mean square of successive NN interval differences (rMSSD) and the percentage of successive NN intervals that differ more than 50 ms (pNN50) reflect ...

The impulse that starts the contraction of the heart has its origin in an area of the right atrium called the sinoatrial node; it is this special tissue that acts as the normal pacemaker for the heart. The impulse is transmitted in a fraction of a second through the atria to another ...
70 Kenchaiah and colleagues71 investigated the relation between BMI and the incidence of heart failure in the Framingham Heart Study cohort and demonstrated a graded risk from normal BMI to the obese range with no evidence of a threshold, suggesting a possible causative role. Increased hemodynamic ...
(epinephrine and norepinephrine). The PNS located in the brainstem and upper or sacral portion of the spinal cord slows down a faster-than-normal heartbeat by releasing the neurohormone acetylcholine. The SNS and PNS exerts excitatory and inhibitory effects on target tissue41in regulating processes...
Patrick is a 70-year-old diabetic man with a 2-year history of stable chest pain when he exerts himself. He is awoken from sleep with the acute onset of crushing central chest pain which radiates to his neck and left arm. His normal medications include normally aspirin, a diuretic, a ch...
