A fetal heart rate tracing looks irregular on a routine scan, and now you have minutes, not days, to decide whether it is benign ectopy or a rhythm that threatens hydrops.

Maternal-fetal medicine specialists, fetal cardiologists, sonographers, and perinatal nurses are asked to make that call constantly, yet most general obstetric training never covers the M-mode and Doppler technique, the classification framework, or the drug-dosing detail that a real fetal arrhythmia case demands.

Without a structured approach, an ambiguous tracing turns into a delayed referral, an unnecessary maternal transfer, or a missed window for transplacental therapy before hydrops sets in.

This 2026 edition closes that gap with a complete, image-rich reference built for the labor and delivery unit, the fetal echocardiography lab, and the maternal-fetal medicine clinic.

Twenty-five chapters moving from conduction-system embryology and M-mode technique through every major tachyarrhythmia, bradyarrhythmia, and block pattern.

Clear diagnostic algorithms for distinguishing supraventricular tachycardia, atrial flutter, ventricular tachycardia, and antibody-mediated heart block at the bedside.

Practical transplacental and direct fetal pharmacotherapy protocols, including digoxin, flecainide, sotalol, and amiodarone dosing and monitoring.

Fifty detailed clinical illustrations covering cardiac anatomy, M-mode and Doppler tracings, and procedural technique, two per chapter.

Intrapartum planning, neonatal transition, and long-term counseling guidance for every major fetal rhythm diagnosis.

Every copy includes a QR-code link to a companion video course of more than fifty curated teaching videos, organized to mirror the book's chapters for rapid bedside review or structured self-study.

Written by a practicing maternal-fetal medicine physician for the clinicians who carry this responsibility every shift, this reference turns an intimidating rhythm strip into a confident, mechanism-based diagnosis and a clear management plan.
