Two Cases of Supraventricular Parasystole.

PARASYSTOLE is a mechanism resulting from rhythmic formation of impulses from two foci in the heart. In the case of atrial parasystole, one focus is usually in the sino-atrial node and the other somewhere in the atrial myocardium. The focus with the faster impulse formation serves as a dominant pacemaker for the heart. The parasystolic focus characteristically forms impulses with remarkable reg...

Study on Relation between Visual Time Perception and Two Factors of Complexity in Architectural Images and Gender

Perceived time can have a significant impact on vital responses to daily activities and behaviors. Studies have shown that the surrounding environment can also affect human perception from time, place or event. The purpose of this study is to investigate the interrelationship between the environment and, more specifically, the architecture and the time perception of individuals. Also, the study...

Difference equation model of ventricular parasystole as an interaction between cardiac pacemakers based on the phase response curve.

A model of extended ventricular parasystole proposed by Moe et al. (1977) was formulated as a system of nonlinear difference equations by using the phase response curve of myocardial pacemakers. A number of ECG patterns of ventricular arrhythmia such as bigeminy, trigeminy etc. were explained from the property of periodic solutions of the equation. Characteristic properties of special kinds of ...
