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 implant is the surgical placement of a device called an artificial pacemaker. It is a treatment for arrhythmias (abnormal heartbeats). Arrhythmias happen when your heartâs electrical signal causes it to pump too slowly, too quickly, or irregularly. A pacemaker implant uses electrical pulses to help your heart return to a normal heartbeat. Your heart is basically a pump made up of muscle tissue.
