Medición de la frecuencia cardiaca y presión arterial en habitantes del Ajusco, Tlalpan, Distrito Federal, México, utilizando equipo CEDAT / Measurement of cardiac frecuency and blood lpressure in a district of Mexico City

Para mejorar los procedimientos de atención de la salud cardiovascular en México es indispensable que en los centros de salud puedan hacer mediciones precisas con aparatos adecuados y se cuente con valores estándar de la población. Se analizaron en 102 personas la frecuencia cardiaca (FC), presión arterial sistólica (PAS) y presión arterial diastólica (PAD) en situasión de reposo sentados, parados, haciendo 30 sentadillas y nuevamente en reposo, parados y sentados. Se encontró una relación directa entre la magnitud de FC y PA con la supérficie corporal y con la edad cronológica. El reflejo ortostático va disminuyendo en relación con el incremento de años de vida. El ejercicio físico incrementó la FC, PAS y PAD que vuelve a disminuir en los siguientes cuatro a ocho minutos consecutivos al ejercicio en las personas en las tres primeras décadas de vida, mientras que en las otras dos no regresa, dentro de este tiempo, a los valores previos. Este decremento de RO es más pronunciado en los hombres que en las mujeres, aunque las cifras de PA son mayores en mujeres en las dos últimas décadas estudiadas. La distribución de los datos parece seguir la curva de distribución normal y queda dentro de lo descrito para altitudes sobre el nivel del mar menores que la ciudad de México. Al implantar los sistemas de medición que se describen en este trabajo, se podrán detectar al inicio los procesos patológicos que afecten la actividad cardiaca y la presión arterial, en situasiones de alteración del ambiente

To improve theprocedures for cardiovascular health care in Mexico it is necessary to be able to perform accurate measurements of the cardiovascular parameters with appropriate equipment and to count with standard values for the Mexican population at the primary health level. Cardiac frequency (CF), systolic arterial pressure (DAP) and diastolic arterial pressure (DAP) were analyzed in 02 consenting volunteers under resting (seated) and standing conditions as well as during excercise (30 sitting), and again after excercise under resurge conditions. A direct relation was found between CF, SAP and DAP with body surface and age. The orthostatic reflex (OR) diminished with age. Excercise increased FC, PAS and PAD, which decreased four-eight minutes after completing the excercise in those subjetcs under 30 years of age, where as in those aged 30 to 50 years these parameters did not return to their previous values. The RO decrement is more pronounced in men, although arterial pressure values ar higher in women aged 30 to 50 years. Data followed normal distribution curve, agreeing with the data re ported for altitudes lower than that of Mexico City. Implementing the measurement systems described in thi paper will allow early detection of pathology that migh affect cardiac activity and arterial pressure that could b, related to environmental pollution at the first level o medical attention.
