Model Description
3D model of scubaprincess
The models were repaired and checked for printability.

Objective: To picture the regions of the heart from which the bioelectrical signal...さらに表示 (wave of depolarisation) is originating and use this to better interpret an ECG readout.
Audiences: Medical students, AP biology students, anyone who has recently had an ECG and is interested in learning where each of the signals is coming from
Preparation: A basic understanding of heart anatomy and the conducting system of the heart
Steps: Print and look.
Results: This is meant to be used a tool during an introduction to ECG interpretation. The next step (and potential assessment of what they learned) would be for the students to look at a real trace and determine the electrical axis.

As a part of my training to become a medical doctor, I have been tasked with learning to read an Electrocardiogram (ECG). This is an essential part of every medical student's physiology exam and indeed, is one skill that you pretty much know that you will get to use once clinical training has begun. Therefore, it struck me as terribly strange and, quite frankly, irresponsible that it was taught so badly, as the ability to quickly diagnose and localise a heart attack or other pathological heart condition could mean the difference between life and death.

All of the standard textbooks use the same empty phrases, the same 2D images showing the chest from the exact same frontal view. There are a plethora a Youtube videos but who has the time to search through them all to find one that will actually be useful (watching one on the topic takes roughly 15 minutes and what med student has that kind of time to spare?).

An ECG is a non-invasive technique that provides graphical representation of the electrical activity of the heart.
The ECG is a 2D trace on a piece of paper. Okay. But, my professors kept repeating that we have to imagine the electrical activity moving in 3D in order to understand what the different traces are telling you. There are typically 12 (sometimes just 6, sometimes 15, there could just be one) different traces originating from 9 different electrodes and 3 leads (Electrode = a physical terminus placed on the patient (either + or -); Lead = an imaginary axis created between electrodes with both a positive and negative terminus). The way you read it is you compare the different heights and orientations of the PQRS waves and use that to decide the direction in which the wave of depolarisation is travelling.
