Concealed Conduction and Concealed Extrasystoles,o small to be sensed by surface electrodes. Any impulse that only partially traverses the conduction pathway, but stops before reaching and depolarizing either atrial or ventricular muscle, will leave no deflection on the surface electrocardiogram. Since the impulse produces no deflection that signa黄油没有 发表于 2025-4-1 11:27:33
The Ventricular Arrhythmias, wide, exhibit axis deviation, and have a range of bizarre morphologies. In some cases, however, ventricular ectopic impulses arise in the distal conduction structures themselves and therefore exhibit narrow QRS complexes. Three basic mechanisms are thought to account for the majority of ventricular使更活跃 发表于 2025-4-1 15:15:02
Exit Block,e, atrial or ventricular muscle in order to produce a deflection on the scalar electrocardiogram. Impulse conduction frequently fails ., resulting in atrioventricular, fascicular, or bundle branch block. But conduction may also fail ., a condition known as . Exit blocks are recognized between the siFlavouring 发表于 2025-4-1 21:54:22
Parasystole,inherently fastest pacemaker, the sinoatrial node, reaches and passively depolarizes the slower, subsidiary pacemaking sites before they can depolarize spontaneously. The sinus node maintains exclusive control of cardiac rhythm both because it has the fastest rate of spontaneous depolarization and b
