[Comparative analysis of parameters of corrected and uncorrected QT-interval dispersion of magneto-, electrocardiography and isomagnetic maps in patients with ischemic heart disease].

AIM: To compare possibilities of magnetocardiography (MCG) and electrocardiography for assessment of regional dispersion of ventricular recovery time using parameters of corrected and uncorrected QT-interval dispersion (DQTs and DQT). MATERIAL: Twenty three patients with class II angina pectoris including 11 patients with history of myocardial infarction (MI) and 13 practically healthy subjects. RESULTS: Mean DQT and DQTc were significantly higher (p<0.005) in patients than in healthy subjects according to both techniques. Values of DQT and DQTc obtained by MCG were higher in patients with history of MI compared with those without MI (p=0.006 and 0.02, respectively). There was a significant positive correlation between age and DQT and DQTc determined by electrocardiography. Mean number of T-wave dipoles was significantly higher in patients than in healthy subjects. Substantial positive correlation was found between number of T-wave dipoles on isomagnetic maps and age in both patients and healthy people. CONCLUSION: The method of MCG gave supplementary information on the state of ventricular depolarization in patients with ischemic heart disease.

[The diagnostic potentials of magnetocardiography in the combined examination of patients with cardiomyopathies].

Diagnostic potential of magnetocardiography (MCG) was elucidated in comparison to ECG and echo-CG in 8 patients with cardiomyopathy (CMP) versus 28 healthy males. Elements of normal MCG curve were characterized in relation to incidence rate. Changes in MCG curve were considered with regard to hypertrophy of basal interventricular septum. In left ventricular hypertrophy MCG showed shifts corresponding to the degree of ventricular dilation. MCG diagnostic opportunities are shown in detection of right ventricular hypertrophy in the presence of the right His bundle blockade in patients with dilated CMP.

[Magnito-, electro- and echocardiography in detecting symptoms of the "hypertensive heart"].

The study compared diagnostic potential of magnetocardiography (MCG), electrocardiography (ECG) and echocardiography (echo-CG) in 18 patients with arterial hypertension (AH). 32 healthy males served as control. Elements of MCG from normal subjects have been analyzed morphologically in 36 points of precordial leads. Left ventricular hypertrophy was registered at echo-CG, MCG, ECG in 11 (61%), 16 (84%) and 7 (34%) of the AH patients, respectively. Left atrial hypertrophy was discovered primarily by echo-CG and MCG. Defects in ventricular repolarization were recorded by MCg in 7 (39%) patients basing on MCG, echo-CG and rarely ECG signs of left ventricular hypertrophy. MCG is recommended as an effective tool in diagnosis of "hypertensive heart".
