“…The MEA membrane provided multi-site ECG acquisition [ 17 ], with favorable spatial resolution as well as SNR, which other systems fail to provide [ 17 ]. The wireless feature under development will further enable real-time monitoring of intrinsic ECG with freely swimming fish [ 20 , 39 ]. Although full-feature ECG signals may not be acquired using the newly developed PDMS apparatus, it provides high-throughput screening of multiple fish simultaneously and would be suitable for those applications in which only heartrate and heartrate variability features are of interest.…”

“…In this context, our group has been developing the wired and wireless flexible MEA “ECG jacket” devices to be worn by the animal (zebrafish and neonatal mice) for real-time ECG monitoring and assessment [ 17 , 19 , 20 , 21 ]. Recently, we also developed a novel apparatus to house and record ECG signals of multiple awake fish simultaneously [ 19 ].…”

Heart disease is the leading cause of mortality in the U.S. with approximately 610,000 people dying every year. Effective therapies for many cardiac diseases are lacking, largely due to an incomplete understanding of their genetic basis and underlying molecular mechanisms. Zebrafish (Danio rerio) are an excellent model system for studying heart disease as they enable a forward genetic approach to tackle this unmet medical need. In recent years, our team has been employing electrocardiogram (ECG) as an efficient tool to study the zebrafish heart along with conventional approaches, such as immunohistochemistry, DNA and protein analyses. We have overcome various challenges in the small size and aquatic environment of zebrafish in order to obtain ECG signals with favorable signal-to-noise ratio (SNR), and high spatial and temporal resolution. In this paper, we highlight our recent efforts in zebrafish ECG acquisition with a cost-effective simplified microelectrode array (MEA) membrane providing multi-channel recording, a novel multi-chamber apparatus for simultaneous screening, and a LabVIEW program to facilitate recording and processing. We also demonstrate the use of machine learning-based programs to recognize specific ECG patterns, yielding promising results with our current limited amount of zebrafish data. Our solutions hold promise to carry out numerous studies of heart diseases, drug screening, stem cell-based therapy validation, and regenerative medicine.
