The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]
, 1955 Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Artificial intelligence for heart rate variability analyzing with arrhythmias [PDF]
, 2019 Introduction. Existing standards of Heart Rate Variability (HRV) technology limit its use to sinus rhythm. A small number of extrasystoles is allowed, if the device used has special procedures for the detection and replacement of ectopic complexes ...

Pharmacological analysis of sinus rhythm.
Folia Pharmacologica Japonica, 1993 The SA nodal pacemaker activity is regulated dominantly by autonomic nervous elements, i.e., sympathetic and parasympathetic nervous factors. In addition, circulatory bioactive substances and physicochemical factors also modify changes in sinus rate. Exogenously applied substances exert their actions on sinus rate directly and/or indirectly.

Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram [PDF]
, 2004 Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters.

Electrocardiography in horses, part 2: how to read the equine ECG [PDF]
, 2010 The equine practitioner is faced with a wide variety of dysrhythmias, of which some are physiological. The recording of an exercise electrocardiogram (ECG) can help distinguish between physiological and pathological dysrhythmias, underlining the ...
