Hallazgos electrocardiográficos en pacientes hipertensos del programa de vigilancia y control de la hipertensión arterial de ASSBASALUD ESE, Manizales, Colombia

Background. Systemic blood pressure (HBP) is a multifactorial disease that includes elevated blood pressure levels, cardiovascular risk factors and left ventricular hypertrophy. Objective. To analyze the electrocardiographic changes in hypertensive patients enrolled in the hypertension surveillance and control program at ASSBASALUD ESE, Manizales, Colombia in 2012. Materials and methods. Cross-sectional study that involved 102 patients. The variables used were electrocardiogram indexes as Cornell, Sokolow Lyon, Macruz and P wave duration. It took a 12-lead electrocardiogram for each patient executed at ASBASALUD ESE, La Asuncion. Results. The average age was 62 years, 58.5% were in the prehypertension range, also 18.6% had abnormal heart rate, 26.3% abnormal P wave duration, 34% abnormal cardiac axis, 64.6% abnormal Macruz index, 10.8% abnormal Sokolow-Lyon index, 10.8% abnormal Cornell index, 5.1% positive P-wave terminal force, 7.8% had right bundle branch block. The rank of hypertension showed significant relationship with the level of Cornell (p=0.000) and Sokolow-Lyon (p=0.016) indexes. A significant relationship between systolic blood pressure value and Cornell (p=0.010) and Sokolow-Lyon indexes were found (p=0.001), likewise diastolic blood pressure value and Sokolow-Lyon index value showed relationship (p=0.001). Conclusions. It is confirmed, in this population of hypertensive patients, that the indexes show variation according to level of hypertension, as well with the values of systolic and diastolic blood pressure are Cornell and Sokolow-Lyon indexes.
