Cardiovascular scientists interested in recording and/or interpreting in vivo surface ECG for adult zebrafish.
Webinar Summary
- Describing the four major steps in recording in vivo surface ECG for adult zebrafish
- Defining single-lead vs dual-lead electrode positions
- Critiquing ECG recording quality
- Performing basic interpretation of adult zebrafish cardiac depolarization, repolarization, and heart rate variability from single-lead ECG
- Performing basic interpretation of adult zebrafish Einthoven triangle and cardiac axis from dual-lead ECG
- Diagnosing arrhythmias, conduction blocks, and drug effects/toxicities by distinguishing pathologic deviations from normal ECG patterns
Zebrafish is a popular high-throughput vertebrate model to study human cardiac electrophysiology, arrhythmias, and myopathies. One reason for this popularity is the purported striking similarities between zebrafish and human electrocardiograms (ECGs). While human ECG, discovered 120 years ago, remains a standard technique in routine clinical practice, establishing similar standards for routine adult zebrafish cardiac research faces unique challenges. Yet, in vivo surface ECG offers the single most practical, economical, if not unique, solution to study adult zebrafish in vivo cardiac electrophysiology and arrhythmias.
