Resting heart rate is controlled by pacemaker cells in the right atrium wall, which generate electrical impulses causing muscle contraction.
Le rythme cardiaque au repos est contrôlé par un groupe de cellules dans la paroi de l'oreillette droite, appelées stimulateur cardiaque, qui génèrent des impulsions électriques pour provoquer la contraction musculaire.
| Front | How is the resting heart rate controlled in our heart? |
|---|---|
| Back | It is controlled by a group of cells in the right atrium wall that act as a pacepaper. These cells produce a small electic impulse which spreads to the surrounding muscle cells, causing them to contract. |
