Steps

1. 1.
   Establish light-based cardiac actuationactuation modality

   Provide contactless, cell-selective control of cardiac electrophysiology.

   Actuation is required before a combined all-optical system can perturb cardiac electrophysiology.

2. 2.
   Acquire optical electrophysiology readoutsensing modality

   Measure cardiac activity, including electrical signals, calcium dynamics, and metabolism.

   Readout is needed so that the effects of optical actuation can be observed and analyzed.

3. 3.
   Combine optical actuation and sensingintegrated all-optical system

   Enable contactless actuation and sensing in one cardiac electrophysiology workflow.

   The review explicitly presents the merger of optogenetics and optical mapping as the key integrative advance after the individual modalities are established.

4. 4.
   Demonstrate ex vivo imaging and in vivo pacingtranslational validation

   Show that all-optical imaging works ex vivo and that optogenetic pacing can be reliable in vivo.

   The abstract uses these demonstrations as later-stage evidence that the field is moving toward clinical use.

5. 5.
   Improve analysis with motion tracking and computationanalysis enhancement

   Reduce dependence on motion uncoupling and improve analysis of complex optical data.

   These methods are described as enhancements that address practical bottlenecks after optical data acquisition is in place.

6. 6.
   Advance toward implantable closed-loop devicestherapeutic deployment platform

   Translate optical electrophysiology into implantable pacemaker and defibrillator systems.

   The review presents implantable closed-loop optoelectronics as a downstream therapeutic direction enabled by prior optical and computational advances.
