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.
When you have follow-up appointments, your doctor can retrieve this information and use it to check how well your heart and the pacemaker are working. Most ordinary household electrical equipment is safe to use and won't interfere with your pacemaker. This includes microwaves, as long as they're in good working order.
