How hard is it to read an ECG? Can it be taught online? Do all doctors know how to read an ECG?

Learning to read an electrocardiogram (ECG) is not a simple task. It takes time and dedication to understand the complexities of each waveform. However, with the right resources and guidance it can be achievable for a motivated student.

There are several courses available online that can teach people how to read an ECG, including those provided by universities like Harvard Medical School, Johns Hopkins University, and WebMD. These courses usually include lectures on anatomy and physiology related to reading an ECG as well as practical experience interpreting diagrams or images of ECGs from real patients. While this type of education is beneficial in teaching someone the fundamentals of understanding ECGs, on-the-job training or personal mentorship from a doctor may be necessary before one becomes truly proficient in its interpretation.

Not all doctors necessarily know how to interpret an ECG with ease; depending on their specialty (such as internal medicine versus cardiology), some may have more familiarity than others when reading these results. Generally speaking though, most medical professionals have knowledge about basic heart rhythms so they can quickly identify any abnormality seen on an ECG report without having extensive expertise in its interpretation beyond that point.
