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.
He or she will slip the pacemaker's small metal box through the cut, place it just under your skin, and connect it to the wires that lead to your heart. The box contains the pacemaker's battery and generator. Once the pacemaker is in place, your doctor will test it to make sure it works properly. He or she will then sew up the cut.
