ECG, taught with method and science.
Aprenda ECG was born in Brazil out of a real need: a place to study, practice and look up ECGs with clinical depth, up-to-date science and a focus on reasoning.
Here the ECG isn't a list of criteria to memorize. It's a tool for medical decision-making, approached with method, context and the best available evidence.
Aprenda ECG is a DoctorQuest product, a medical education platform.
Evidence over myth
We revisit old concepts in light of current literature and favor ECG interpretation grounded in pathophysiology, clinical context and evidence.
Reasoning before criteria
The goal isn't to memorize isolated findings, but to understand the tracing, recognize patterns and turn the ECG into a clinical decision.
For every stage of training
From your first ECG to advanced topics, the content grows with you, with clarity, depth and practical application.
Everything we've built to help you learn ECG
Matheus Kiszka Scheffer
Aprenda ECG is led by Dr. Matheus Kiszka Scheffer, a Brazilian cardiologist and arrhythmia specialist who works in Tele-electrocardiography at the Instituto Dante Pazzanese de Cardiologia in São Paulo and has experience training residents, students and physicians.
His career spans clinical practice, teaching and research. He sees the ECG as a decisive tool in patient care, and also as a field where many concepts are still taught in a fragmented, rote or outdated way.
He has written three books on the subject, including the well-regarded Eletrocardiograma de A a Z. At Aprenda ECG, his mission is to turn that knowledge into a clearer, more practical, evidence-based way to study.
