Genesis of cardiac arrhythmias.
Activity of Automatic Cells The normal rhythm of the mammalian heart results from spontaneous excitation of cells in the sinoatrial node. These cells possess the property of automaticity.' The transmembrane potential of working muscle fibers in the atria or ventricles demonstrates a rapid depolarization on excitation (phase 0), a period of variable duration during which the cell repolarizes (ph...

متن کاملThe Genesis of Certain Cardiac Arrhythmias in Fish
The hearts of both elasmobranch and teleost fish are known at times to beat at a particular phase of the respiratory cycle and thus to exhibit a regular rhythm locked to that of respiration (Lyon, 1926; Lutz, 1930; Satchell, i960; Shelton & Randall, 1962). In the laboratory, the hearts of Squalus acanthias and Mustelus antarcticus usually exhibit a 1:2,1:3 or 1:4 rhythm, the P wave of the elect...
متن کاملFrequency of Cardiac Arrhythmias in Patients with Aluminum Phosphide Poisoning
Background: Cardiac failure is the major lethal consequence of aluminum phosphide (AlP) poisoning. This study was designed to determine the frequency of cardiac arrhythmias in patients with AlP poisoning. Methods: In this prospective cross-sectional study, patients with definitive history of AlP poisoning treated at emergency department of Allied Hospital Faisalabad, Faisalabad, Pakistan, from ...
