I have spent thousands of hours (yes, thousands) looking at 12-lead ECG tracings, studying ECGs for the cardiology boards, interpreting ECGs for direct patient care, and developing ECG tutorials ...

Of course, such an approach requires more than a single ECG tracing. Incorporation of these ideas in one's "routine" is not cumbersome, necessary information derives from ubiquitously available ...

Note the R/S ratio in V1 is quite high. Now, here is the same patient with a posterior ECG tracing. Leads V7 to V9 were added. Leads V1 and V2 were moved a bit just to confuse us. There is not ...

And because it’s also quite simple to implement the required sensors, it makes sense that electrocardiogram (ECG) machines are a popular choice among introductory medical electronics projects.

Figure 18B shows the 12-lead ECG of the entrainment tracing of Figure 18A. The QRS morphology in all 12-lead ECGs during entrainment is identical to that of pacing in the absence of tachycardia as ...
