Through the chords of life — whether it's moving adagio (slow and stately) or allegro (quickly) for you — your heart works in a four-part harmony.
Start at the top of the range:
The right atrium, the highest point — like a soprano — of the blood's movement into and through the heart.
Then moving down to the right ventricle, the alto.
Then the blood courses, vivace, through the pulmonary artery to the lungs — where it deepens with oxygenation, the tenor —Ìýand back to the left atrium.
From there, down to the left ventricle — the bass — the next contraction a boom of enriched blood heading out of the aorta and to the body, only to return da capo, hitting that high note at the top before starting the run all over again.
But when some part of the heart loses time, a conductor can restore form to its proper pace. We call that maestro a pacemaker.
But what if the maestro did not have his baton to deliver energy to the orchestra?
Would that not be like a pacemaker not having its cardiac leads?
Let us introduce you toÌý.Ìý
