It is important to note that fibrotic deposits and more in general scar tissue within the myocardium alter the normal electric conduction of the heart, generating profound changes in the normal electrical impulse.
Invented in 1840, the first battery electric clock was driven by a spring and pendulum and employed an electrical impulse to operate a number of dials.
Surprisingly, the electrical impulse came from a simple vein that was believed to be electrically inert and of no possible interest to an electrophysiologist.
The pacemaker uses a mild electrical impulse to continuously control the heartbeat.
The new pacemakers deliver an electrical impulse that synchronizes the pumping of the ventricles.
This sets up an electrical impulse circuit within the ventricle that may progress into an arrhythmia.
These chips translate an external stimulus like a sound into an electrical impulse delivered to the brain.
Once the electrical impulse is generated in the sinoatrial node, it is propagated rapidly throughout the heart.
The hairs wobble in response to changes in water pressure, and their movement is translated into an electrical impulse in a nearby nerve.
About halfway up the tower, a solenoid relays an electrical impulse from the clock mechanism to small coils that activate the hammers that ring the bells.
A tiltmeter works like a carpenter's level, with a bubble in the middle that sets off an electrical impulse when it shifts.
