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; 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 (WPW) Syndrome is a combination of the presence of a congenital accessory pathway and episodes of tachyarrhythmia.
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 = high grade LAD or LM coronary lesion
Ventricular Tachycardia = 3 or more VEB at a rate of > 130 beats/min. If > 30 seconds = sustained; can be monophoric or polymorphic
Ventricular Fibrillation requires a initiating stimulus in a susceptible myocardium.
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.
Severe Heart Failure Management
Right ventricular infarction. Suspect in all patients with inferior STEMI
Preload = initial myocardial fibre length prior to contraction; determined by anything that effects ventricular volume at the end of diastole
Pericarditis = inflammation in the pericardium
