The cutaneous R-pulse interval: Its application as a clinical measure of neonatal cardiovascular function
The time interval from the onset of the R wave of the ECG to the onset of the cutaneous capillary pulse wave, i.e., cutaneous R-pulse interval or RPIC, was evaluated in 21 full-term and 22 preterm infants as a measure of cardiovascular function. RPIC showed a significant linear relationship with bir...
