You could create a comb function like this: Theme. % Create 1 second long signal of all zeros. % Each time element is defined to be 0.000125 second long. t = zeros (1, 5*1600); % Create impulses every 0.000625 seconds. % That would mean it occurs every 5th sample. WitrynaThe normal electrophysiologic behavior of the heart is determined by ordered propagation of excitatory stimuli that result in rapid depolarization and slow repolarization, thereby generating action potentials in individual myocytes. Abnormalities of impulse generation, propagation, or the duration and configuration of individual cardiac action ...

Cardiac electrophysiology: action potential, automaticity
Witryna5 wrz 2006 · The results of the present study provide important functional and mechanistic insights into cardiac automaticity and have further refined an HCN gene-based therapy for correcting defects in cardiac impulse generation. Publication types Research Support, N.I.H., Extramural WitrynaAbnormal impulse formation can cause arrhythmias by the following two mechanisms: Increased or abnormal automaticity Triggered activity Increased or abnormal automaticity As discussed in Chapter 1 there are several structures in the heart that possess automaticity (i.e ability to depolarize spontaneously). These structures are as follows: WitrynaIn different regions of the heart, action potential waveforms are distinct, owing to differences in Na (+), Ca (2+), and K (+) channel expression, and these differences contribute to the normal, unidirectional propagation of activity and to the generation of normal cardiac rhythms. how to reset a directv remote control
