Physiology of the Heartbeat,lly, the heartbeat is initiated in the SA node. The AP generated propagates from one muscle cell to the next until it has spread over the entire atrial wall and reached the AV node at the boundary between the atrium and the ventricle. Because of the low conduction velocity in the AV node, there is a

Monitoring the Electrical Activity of the Heart, All together, the individual APs in the heart produce an overall time-varying voltage difference between the excited and unexcited parts during a contraction phase. This voltage signal can be recorded with electrodes attached to the surface of the body, amplified and displayed with a multichannel r

Pacemaker Technology, regulative influences. Through sympathetic innervation, these mechanisms permit inotropic and chronotropic adaptation of cardiac output to physical workload. The automatic action begins at the SA node. If its impulse formation ceases, ., an SA blockage, or if there is a total AV block, the remainin

Status of the Application of Corporeal Control Parameters,e signal transducer and a suitably robust algorithm must be available. Table IX summarizes the available sensor technology necessary to implement one of these adaptive strategies. The same high quality requirements imposed on the pacemaker also apply to the permanently implanted regulatory system. A

Cardiac Control Parameters,ol information . A particularly useful control signal available via a cardiac parameter is the sympathetic tone, which is independent of the heart rate . This signal is an efferent control signal from the ANS to regulate cardiac output.

The Stimulating Electrode,dal stimulus pulses to the myocardium as introduced by Furman in 1958 . The response of an excitable cardiac muscle cell to an external stimulus depends on the electrical field strength—that is, on whether the field depolarizes the diastolic membrane potential sufficiently to generate spontaneo

The use of alloplastic materials in replacement surgery has a long history, and has mainly involved implants in the skeletomuscular system .
