Abstract

Breath hold diving induces several physiological effects. The authors speculate that next to bradycardia, vasoconstriction, splenic contraction and blood shift, the form of the ECG and especially the PQ interval are also affected. Investigations of this effect requires a high resolution ECG monitor which is also capable of recording depth. This paper describes our data logger prototype. It samples ECG data at 1200 Hz, is equipped with three temperature and a pressure sensor that allows depth measurement up to 140 m and stores all the data in an ASCII text file on a SD flash card in FAT 16 or FAT32 file format. The prototype is then encapsulated in a Lexan tube with an outer diameter of 42 mm and an overall length of 18cm that should withstand 20 bar pressure equal to 200 m depth.
