Hint: The sinoatrial node is also called the pacemaker of the heart. It is one of the crucial components in the cardiac conduction system, the technology that controls the heart rate.
Complete solution:
Pacemakers function only when your heartbeat is extremely slow, the pacemaker transmits electrical signals to your heart to rectify the beat.
Some modern pacemakers have detectors that observe body motion or breathing rate, which signal the pacemakers to boost heart rate during a workout, as desired.
Two tinier, leadless pacemakers, which can be seeded rapidly into the heart, have been authorized for use in the United States. Because a clue isn't needed, this equipment can underrate distinct threats and speed recovery. Although this kind of pacemaker seems to work well and safely, a longer-term analysis is desired.
The functions of pacemaker:
1. Pulse generator: This tiny metal container houses artillery and the electrical circuitry that governs the rate of electrical vibrations delivered to your heart.
2. Leads: One to three flexible, insulated cords are each positioned in a chamber, or chambers, of the heart and transmit the electrical vibrations to regulate your heart rate.
The real or synthetic pacemaker has a purpose to deliver electrical instincts from the atrium for contraction and pumping activity into the ventricles.
If in any case, the pacemaker comes to be non-functional then, cardiac muscles do not sustain the coordinated rhythmic motion.
So, the correct answer is an option ‘Cardiac muscles do not undergo coordinated rhythmic movements.’
Note:
A pacemaker is a tiny tool that's positioned under the skin in your chest to enable the management of your heartbeat. It's employed to enable your heart to beat more regularly if you have an unstable heartbeat, especially a slow one. Not every pacemaker is durable. Provisional pacemakers can regulate specific categories of situations. One may require a temporary pacemaker just after heart surgery.
