what is the electrical part of your heart?
the sinoatrial node
each part of the heart is susceptible to failure or dysfunction and the heart can be divided into the mechanical and the electrical parts.









































the electrical part of the heart is centered on the periodic contraction (squeezing) of the muscle cells that is caused by the cardiac pacemaker located in the sinoatrial node.









































the study of the electrical aspects is a sub-field of electrophysiology called cardiac electrophysiology and is epitomized with the electrocardiogram (ecg/ekg).

the train heating system was fed over a separate oil propulsed main switch with 1000 v. this installation was later replaced by a spearte heating transformer. the oil powered main switch was replaced by a heating hopper.









































section::::technical details.:the electrical part.:electrical brake.









































the sbb requirement requested an electrical brake. this brake was shown in the blueprints but only in dashed lines and therefore not mounted in the locomotive. this brake was never upgraded because this “stopgap” locomotive was never used for services on the gotthard railway line.
