Take the D scale for example. Start on the D note at the second fret and move up the scale like this to the next D: If you play this same pattern up two frets (so the E is the first note you play), youâll have an E major scale. The same goes for any other pattern you can spot in these scale maps.
A pacemaker signals the heart to beat when the heartbeat is too slow or irregular. A pulse generator is a small metal case that contains electronic circuitry with a small computer and a battery that regulate the impulses sent to the heart.
pacemakers fire to jump start the heart, but yes you can die if you have a pacemaker, the pacemaker can still fire for a long period of time after death but the heart doesnt respond to the signal. after death and the batteries die the pacer will stop. also a magnet placed over the pacer will de activate it.
