CARTAYA ORTIZ, Ernesto; DEL PRADO DE LA TORRE, Lisset  and  LEON DUHARTE, Dalgis. Modifications of the electrocardiographic tracing and heart contractility in patients with ischemic cardiopathy rehabilitated by means of physical exercise. MEDISAN [online]. 2019, vol.23, n.1, pp.65-76. ISSN 1029-3019.

A descriptive, longitudinal and prospective investigation of 41 patients with a history of acute myocardial infarction who were part of a program of cardiovascular rehabilitation in the Service of Physical Therapy and Rehabilitation from "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out from May, 2017 to the same month in 2018, with the aim of evaluating the effect of the physical training on their cardiovascular function. The cardiovascular function was examined through the echocardiogram and the electrocardiogram, before and after the program was applied, and at the end of the study a positive modification of the echocardiographical and electrocardiographical variables was obtained with a higher degree of recovery of the segmental contractility. It could be concluded that the program had an important role in the restoration of the heart function and, with it, the physical and psychological capacity of the patients improved, so that it was beneficial for them and for the society.
