Abstract
The climbing of high mountains, like the Himalayas,
comes accompanied, as result of the deficit of oxygen, of
certain changes of the hemodynamics, that can derive
sometimes in High Altitude Pulmonary Edema (HAPE).
With the objective to analyze the cardiological effects
of that hemodynamics changes, a satellite monitoring of
phonocardiographic (PCG) signals and pulseoxymetric
data of a mountain climber was made during the
development of the climbing to the Broad Peak, of 8,047
meters, located in the mountain range of the Karakorum,
in Pakistan.
Using an electronic estethoscope, signals were
registered and sent to the hospital medical staff in Murcia
by means of satellite phone, to be compared with basal
registers. Different techniques for analysis in frequency
and time domains were developed, mainly to detect and
measure the first and second heart sounds and to observe
possible modifications in the phonocardiographic
patterns related to the altitude and pulseoxymetric data.
