A study of 61 patients with acute left ventricular posterior myocardial infarction examined ventricular complex variations, recorded from standard and precordial leads; in fatal cases, ECG findings were compared with pathoanatomical studies of the heart. Precordial mapping was shown to considerably increase the efficiency of electrocardiographic diagnosis(More)
A method is proposed for the estimation of intravital necrotic weight in myocardial infarction (MI) that permits the assessment of necrotic weight at any hour of the necrotic MI stage. It is based on a mathematical model of nonlinear diffusion of a biochemical enzyme into the blood from necrotized tissue, followed by nonlinear enzyme washing out of the(More)
Based on the results of examination of 58 patients with myocardial infarction, the authors propose a method for diagnosing posterior myocardial infarction by abdominal electrocardiographic mapping. The anterior abdominal wall shows the area from which one may record the direct markers of posterior myocardial infarction: abnormal Q wave, R wave regression,(More)
In a study of 46 patients with acute posterior myocardial infarction and different patterns of the necrotic period, anatomical measurements of necrosis weight were compared with the measurements of R wave amplitude and the depth of Q and S waves (the QS complex), recorded from standard leads and precordial mapping, and with serum CPK-MB activity. The(More)
Superficial cardiac ECG mapping was performed to examine 16 patients with acute myocardial infarction and 13 with hypertrophic cardiomyopathy who had electrocardiographic signs of focal myocardial changes (QS complex and/or abnormal Q wave). Deviation of instantaneous ventricular depolarization vectors in the direction opposite the malfunctioning myocardial(More)
To test the reparative capacity of stromal cells in myocardial infarction, rats were injected with granulocyte-monocyte-colony stimulating factor (GM-CSF) (leukomax), a cytokine known by its ability to raise a level of stromal cells in the blood, during first three days after coronary artery ligation. Only 10 of 17 rats (59%) survived 4 weeks in this group(More)
A study of 28 patients with acute inferior myocardial infarction, who died 3 days after the attack, involved the comparison of necrosis weight data, as determined anatomically, with those obtained through the measurement of the R wave height and the Q wave (QS complex) depth, taken from standard leads and amplified remote leads from limbs. The comparison(More)
