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 Brigham and Women's Hospital answered. Recovering from a pacemaker implantation (surgical insertion of a small device to regulate your heart rhythm) is rather quick. You may either go home the same day, or most patients spend one night in the hospital following the procedure. There may be some minor discomfort following the procedure. Tylenol or other over-the-counter pain relief medications can be used as needed. Most individuals feel fine within a few days.
