Some aspects of sleep disturbance in coronary patients.

Of 42 coronary care patients studied during 10 hr. of polygraphically recorded sleep, 28 were in an open-ward coronary care unit and 14 were in a semi-private telemetry unit. The observed sleep disturbances were not a function of type of unit, length of hospitalization, sex, or medications. Sleep was significantly less fragmented in those patients judged less severe in pathology. These results indicate that alterations in normal sleep patterns occur routinely within coronary care environments, even in the absence of disturbing environmental stimuli and suggest that a closer analysis be made of sleep in these settings in light of the known relationships between sleep and cardiac function.

Psychological aspects of cardiac arrhythmia.

A review of data from a wide spectrum of research studies suggests that psychological-emotional factors can significantly influence and alter the incidence of cardiac arrhythmia. While the existing data are, in many cases, difficult to interpret because of theoretical and methodological problems, sufficient evidence does exist to warrant a concerted investigation into the total involvement of psychological factors in cardiac arrhythmia.

Left ventricular posterior wall motion in patients with the Wolff-Parkinson-White syndrome.

Echocardiography appears to be a sensitive technique for detecting disturbances in left ventricular posterior wall motion in subjects with WPW type A. The characteristic abnormality consists of premature anterior displacement of the LVPW shortly after the inscription of the delta wave. The ability to detect abnormal wall motion is influenced by the size of the segment of myocardium undergoing pre-excitation, the site of insertion of the anomalous pathway, and its accessibility to echocardiographic study. The results of this study support the concept that WPW type A represents premature excitation of the posterior left ventricular wall in some patients. Moreover, such pre-excitation may be associated with an altered pattern of left ventricular contraction. A similar pattern of LVPW motion was not observed in a large group of randomly selected clinical echocardiograms including a variety of intraventricular conduction disturbances.

Sleep-waking changes in cardiac arrhythmia in a coronary care patient.

A single case is reported in whom ventricular cardiac arrhythmias were related to the occurrence of polygraphically verified sleep. A strong relationship was found to exist between the heart rate in any one minute and the number of premature ventricular contractions, with higher rates associated with a greater number of these ectopic beats.
