Venous Return and Shock
This page is under construction OVERVIEW “Obviously, except under momentary conditions the venous return and the cardiac output must be equal.” — Arthur Guyton STARLING’S LAW By raising or lowering an artificial venous reservoir, Starling showed that increased right atrial…

This page is under construction OVERVIEW Cardiorenal syndromes (CRS) are disorders of the heart and kidneys whereby acute or long-term dysfunction in one organ may induce acute or long-term dysfunction of the other CRS is characterised by the triad of…
Troponin in Critical Illness
Troponin abnormality is set at the 99th percentile in the healthy population, As the tests become more and more sensitive, the absolute cutoff value for “abnormal” has become lower and lower and the test has become less specific for myocardial infarction
Electrical Storm
Electrical Storm; 3 or more sustained episodes of ventricular tachycardia (VT), ventricular fibrillation (VF), or appropriate implantable cardioverter-defibrillator (ICD) shocks during a 24-hour period
Wolff-Parkinson-White Syndrome
Wolff-Parkinson-White (WPW) Syndrome is a combination of the presence of a congenital accessory pathway and episodes of tachyarrhythmia.
ICU Acquired Weakness (ICUAW)
ICU Acquired Weakness (ICUAW) includes critical illness myopathy (CIM); critical illness polyneuropathy (CIP), or a mixture of both (myopathy is typically predominant); very common in the mechanically ventilated (25-60% in those mechanically ventilated for > 7 days)
Wide Complex Tachycardia
TYPES Ventricular Tachycardia (VT) Wide complex SVT Accelerated idioventricular rhythm Ventricular Fibrillation (VF) VENTRICULAR TACHYCARDIA see separate document WIDE COMPLEX SVT see VT document for Brugada algorithm ACCELERATED IDIOVENTRICULAR RHYTHM (AIVR) encountered in an inferior AMI often causes haemodynamic compromise…
Wellens Syndrome
Wellens Syndrome = high grade LAD or LM coronary lesion
Ventricular Tachycardia
Ventricular Tachycardia = 3 or more VEB at a rate of > 130 beats/min. If > 30 seconds = sustained; can be monophoric or polymorphic
Ventricular Fibrillation
Ventricular Fibrillation requires a initiating stimulus in a susceptible myocardium.
Vascular Gas Embolism
Vascular gas embolism (VGE) is the entrainment of air (or exogenously delivered gas) from a communication with the environment into the venous or arterial vasculature, producing systemic effects.
