Cardiac Output
Cardiac Output (CO) = Stroke Volume (SV) x Heart rate (HR) CO = SV x HR changes based on exercise, age and body size. normal adult = 5L/min Stroke Volume (SV) determined by: Preload Afterload Contractility

The LITFL Critical Care Compendium is a comprehensive collection of pages concisely covering the core topics and controversies of critical care.
Cardiac Lesions and Severe Clinical Signs
Cardiac Lesions and Severe Clinical Signs; valvular issues, cardiac anomalies and their murmurs
Cardiac Biomarkers
Biomarkers can potentially be used to detect and monitor a wide range of cardiac conditions in the critical care setting

Beta Blockers to Prevent Perioperative MI
The use of Beta-blockers in perioperative medicine has been an issue of intense research in Anaesthesia. Patients that are believed to benefit from beta-blockers are those with risk factors for ischaemic heart disease (HT, DM, hypercholesterolaemia, previous MI, angina, controlled heart failure)
Atrial Natriuretic Peptide
Atrial Natriuretic Peptide isolated from the right atrium potent diuretic/natriuretic effect on kidney + vasodilator effects on resistance & capacitance of blood vessels released in response to atrial stretching (ie. fluid overload)
Atrial Fibrillation
Atrial fibrillation (AF) is the most common sustained dysrhythmia and is characterised by disorganised atrial electrical activity and contraction resulting in an "irregularly irregular" ventricular response ("fibrillation waves")
Arrhythmias
An approach to arrhythmia, causes, classification and factors contributing to arrhythmogenesis
Arrhythmia Literature Summaries

Afterload
Reviewed and revised 12/6/12 Afterload = left ventricular wall tension required to overcome resistance to ejection (impedance to ejection of blood from the heart into the arterial circulation). developed as ventricular muscle fibres shorten during isovolumetric contraction & ejection phases…
Percutaneous Coronary Intervention (PCI)
Percutaneous coronary intervention (PCI) is the preferred emergency reperfusion strategy in most cases of ST elevation myocardial infarction (STEMI)
Acute Coronary Syndromes
Coronary artery disease accounts for > 30% of death in West and presents acutely as acute coronary syndromes. Acute coronary syndrome (ACS) is a catch all term that refers to ischemic symptoms resulting from acute coronary occlusion
