Inherited Cardiac Arrhythmia Syndromes
Lethal cardiac arrhythmias in individuals with structurally normal heart are often caused by variants in genes that encode cardiac ion channel and -subunits (102). Common inherited arrhythmia syndromes include the congenital long QT syndrome (LQTS), Brugada syndrome (BrS), short QT syndrome (SQT), and catecholaminergic polymorphic ventricular tachycardia (CPVT) (76). Moreover, inherited mutatio...

Sudden cardiac death (SCD) remains one of the most prevalent modes of death in industrialized countries, and myocardial ischemia due to thrombotic coronary occlusion is its primary cause. The role of platelets in the occurrence of SCD extends beyond coronary flow impairment by clot formation.

متن کاملCardiac Arrhythmia: Five Cases
brought to light by a study of them, but because they will serve as a means for demonstrating the principal facts on which the modern conceptions of cardiac arrhythmia are based. First, certain facts as to the anatomy and physiology of the cardiac muscle must be recalled. The primitive heart is a muscular tube, the powerfully contracting chamber is a later development, and the valves and perica...
متن کاملAconitine-induced cardiac arrhythmia.
Renewed interest in the pharmacological action of aconitine has followed the work of Sherf (1947), Prinzmetal et al. (1950 and 1951), and Brown and Acheson (1952). Its use in experimental medicine produces stimulus formation in the dog's heart with auricular tachycardia and in certain circumstances ventricular tachycardia and fibrillation: it has become a useful tool in the hands of the researc...
