RESUMEN
Out of 85 patients with cardiac arrhythmias in the presence of chronic coronary heart disease, 28 who were resistant to ethacisine and allapinine were included into the study. They had frequent and persistent arrhythmias. The patients were divided into 2 groups: (1) the patients receiving intravenous He-Ne laser therapy in combination with one of the above drugs; (n = 17) and (2) those taking He-Ne laser therapy alone (n = 11). The efficacy of the therapies were controlled by 24-hour monitoring. An antiarrhythmic effect was more frequently observed when He-Ne laser was combined with one of the above drugs than when it was given alone (67.4 and 36.3%, respectively).

To study the incidence and nature of cardiac arrhythmias and the changes in the corrected Q-T interval, 60 patients with the prolapsed mitral valve syndrome were examined. All the patients underwent resting ECG and leg isometric exercise. 24-hour ECG monitoring was performed in 48 patients. The latter technique was found to be the most informative tool for detecting cardiac arrhythmias (66.8%). Prolonged corrected Q-T interval (more than 440 msec) was more frequently revealed in leg isometric exercise (41.6%) than in resting ECG (26.6%) and 24-hour monitoring (29.2%). Its degree was directly related to the severity of cardiac arrhythmias in patients with the prolapsed mitral valve syndrome.
