ACUTE HEART FAILURE (CARDIAC SYNCOPE)  Acute heart failure is an illness that hits suddenly and without any earlier symptoms.  It occurs when there is a severe defect in filling, when there is failure of the heart as a pump, either due to severe tachycardia, bradycardia or arrhythmia, and where there is a sudden increase in workload.  The sudden occurrence of tachyarrhythmia in association with excitement that is severe enough to cause acute heart failure presumably results from the exacerbating influence of catecholamines. These are released in association with episodes of excitement and act to heighten the discharge potential of ectopic excitatory foci associated with myocardial disease. An ectopic focus or ectopic foci (An ectopic pacemaker), is an excitable group of cells that causes a premature heart beat outside the normally functioning SA node of the heart. It is thus a cardiac pacemaker that is ectopic, producing an ectopic beat.
