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.

Acute complete heart block in dogs [PDF]
, 1955 A study has been conducted immediately and up to 18 days after the surgical production of complete heart block in dogs. Immediately after surgery cardiac output, coronary flow, and mean arterial pressure were reduced in rough proportion to the degree of ...

New experimental model of acute aqueductal blockage in cats: effects on cerebrospinal fluid pressure and the size of brain ventricles [PDF]
, 2009 It is generally assumed that cerebrospinal fluid (CSF) is secreted in the brain ventricles, and so after an acute blockage of the aqueduct of Sylvius an increase in the ventricular CSF pressure and dilation of isolated ventricles may be expected. We have

What every ICU clinician needs to know about the cardiovascular effects caused by abdominal hypertension [PDF]
, 2015 The effects of increased intra-abdominal pressure (IAP) on cardiovascular function are well recognized and include a combined negative effect on preload, afterload and contractility.

Correlation between 24-hour profile of blood pressure and ventricular arrhythmias and their prognostic significance in patients with arterial hypertension [PDF]
Vojnosanitetski Pregled, 2008 Background/Aim. Left ventricular hypertrophy (LVH), apart from arterial hypertension, is a risk factor for electrophysiologic heart condition disorder and sudden cardiac death.
