CPR Electrolyte imbalance and cardiac arrest Significant electrolyte imbalances can precipitate cardiac arrest and are potentially reversible etiologies when promptly and appropriately addressed. Both venous…

Clinical chemistry & laboratory medicine Myocardial ischemia and infarction Definition and pathophysiology Myocardial infarction (MI) is a clinical diagnosis that integrates myocardial injury, evidence of acute…

…atria begin to contract again. An unsynchronised shock that happens to fall in the T wave can precipitate ventricular fibrillation, and cardioversion of fibrillation of…

…syndrome [LQTS] and early repolarization syndrome. These conditions have an underlying genetic basis and may precipitate lethal arrhythmias. Long QT syndrome was identified several decades…

…relative to the cardiac cycle, since a shock delivered asynchronously on the T wave during ventricular tachycardia can precipitate ventricular fibrillation, whereas a synchronized shock…

…distress. Delirium is an acute neuropsychiatric syndrome and a clinical diagnosis, often described as acute brain failure. It is precipitated by somatic illness, drugs, poisoning…

…interval can cause serious arrhythmias and sudden cardiac death. QT prolongation can precipitate torsades de pointes, a specific form of polymorphic ventricular tachycardia characterized by…

…AF and acute deterioration is often bidirectional. AF with a rapid ventricular response may precipitate or aggravate haemodynamic decompensation, whereas acute illness and increased sympathetic…

…Atrial arrhythmias, particularly atrial fibrillation and flutter, are common and may precipitate heart failure [8, 10]. Refractory atrial arrhythmias resistant to antiarrhythmic drugs or repeated…

…Conversely, apparently mild lesions may rupture and precipitate myocardial infarction or sudden death. Coronary anatomy must therefore be interpreted within the broader clinical and physiological…
