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.
A pacemaker is a comfort tool -- it keeps your heart rate from going too slow. The heart no longer responds to the pacemaker once a person dies. In most cases, the pacemaker is not an issue. It is important for you to know whether or not you are dependent on the pacemaker all the time or only some of the time.
