Introduction to the Concept of the Pacemaker The term pacemaker, in its broadest psychological and biological context, refers to any natural or artificial mechanism responsible for establishing, maintaining, and regulating specific biological rhythms necessary for homeostasis and adaptive functioning. While commonly associated with the medical device used to regulate cardiac function, the concept extends profoundly […]
ARHINENCCPHALIA ARRHYTHMIA The term arrhythmia refers broadly to any abnormality in the rhythm of the heart, meaning the heart is beating at a rate that is not within the normal range for an individual of that age or exhibiting an irregular pattern of contraction. While the specific nomenclature of “Arhinenccphalia arrhythmia” might suggest a linkage […]
Definition and Context of the SS Interval The term SS Interval serves as the fundamental abbreviation for the shock-shock interval, a critical temporal parameter utilized extensively within the field of behavioral psychology, particularly in experimental paradigms involving aversive conditioning. This interval is defined precisely as the duration of time that elapses between the presentation of […]
BRADYRHYTHMIA: An Encyclopedia Entry Introduction: Defining Bradyarrhythmia A bradyarrhythmia, often synonymously referred to as bradycardia or bradyrhythmia, represents a pathological condition characterized by an abnormally slow heart rhythm. Physiologically, the typical resting heart rate for a healthy adult falls within the range of 60 to 100 beats per minute (BPM). When the heart consistently beats […]
The Psychology and Psychophysiology of Tachycardia The Core Definition: A Psychophysiological Perspective Tachycardia, derived from the Greek terms meaning “swift” and “heart,” is fundamentally defined in medicine as an abnormally rapid heart rate, typically exceeding 100 beats per minute (bpm) in a resting adult. From a psychophysiological perspective, however, tachycardia is viewed less as a […]
Bradycardia Introduction: The Core Definition of Bradycardia Bradycardia is a medical condition fundamentally characterized by an abnormally slow heart rate, typically defined as fewer than 60 beats per minute (bpm) in adults. This physiological anomaly deviates from the average resting heart rate, which usually falls between 60 and 100 bpm, signaling a potential disruption in […]
