Wellens Syndrome
Wellens Syndrome = high grade LAD or LM coronary lesion
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
Features that distinguish Pulmonary Embolus from Right Ventricular Infarction
Pericardial disease
Syncope is transient, self-limited loss of consciousness with an inability to maintain postural tone that is followed by spontaneous recovery. Such an event without loss of consciousness is often termed “presyncope”. Underlying cause is often not found in the emergency department (~50%)
pCO2 gap is a surrogate for cardiac output; pCO2 gap = PcvCO2 - PaCO2; pCO2 gap >6 mmHg suggests a persistent shock state that may be amenable to fluid resuscitation +/- intrope support; a “ScvO2-cvaCO2gap-guided protocol” has been proposed to guide the management of septic shock
