• Human induced pluripotent stem cells (iPSC) offer a novel source for creating human-specific disease models.

Purpose of the Study:

• To review current 2D and 3D in vitro arrhythmia models using iPSC-derived cardiomyocytes.
• To highlight the application of these models in drug development and disease modeling.
• To discuss the integration of gene editing, computational technologies, and machine learning in arrhythmia research.

Main Methods:

• Review of 2D and 3D in vitro models utilizing human iPSC-derived cardiomyocytes.
• Examples of drug development and gene editing applications in arrhythmia modeling.
• Discussion of emerging technologies like computational modeling and machine learning.

Main Results:

• Human iPSC-derived cardiomyocyte models show significant potential for disease modeling, drug discovery, and toxicity testing.
• Current models demonstrate initial success in replicating arrhythmias.
• The field is rapidly advancing, with ongoing efforts to improve maturation, cellular diversity, and readout accuracy.

Conclusions:

• iPSC-derived cardiomyocyte models represent a significant advancement over traditional animal models for studying arrhythmias.
