then slowly repolarize, which is denoted as the T wave on the ECG, leading to cardiac relaxation and completion of one cardiac cycle. The rhythmic activity of the human heart is clearly apparent by ultrasound after only five weeks of gesta-Department of Cardiology Children's Hospital tion. It is remarkable to think how flawlessly the heart performs in the course of one's life, beating 07ف tim...
متن کاملMechanisms of cardiac arrhythmias.
Cardiac arrhythmias are prevalent among humans across all age ranges and may occur in the setting of underlying heart disease as well as in structurally normal hearts. While arrhythmias are widely varied in their clinical presentations, they possess shared electrophysiologic properties at the cellular level. The 3 main mechanisms responsible for cardiac arrhythmias are automaticity, triggered a...
متن کاملCardiac Surgery for Arrhythmias
Surgical treatment for cardiac arrhythmias was initiated in 1968 with the first successful surgical division of an accessory atrioventricular connection for the Wolff-Parkinson-White Syndrome. Subsequent surgical procedures were the left atrial isolation procedure and the right atrial isolation procedure for the automatic atrial tachycardias, corridor procedure and the Maze procedure, developed...
متن کاملBasic mechanisms of cardiac impulse propagation and associated arrhythmias.
Propagation of excitation in the heart involves action potential (AP) generation by cardiac cells and its propagation in the multicellular tissue. AP conduction is the outcome of complex interactions between cellular electrical activity, electrical cell-to-cell communication, and the cardiac tissue structure. As shown in this review, strong interactions occur among these determinants of electri...
