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 ...

Most ECG machines today are able to read the tracings to some degree (with varying accuracy), but it is still incumbent on cardiologists to understand and interpret the ECG tracings. The initial ...

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 ...

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 ...

ECG is a very common and very cheap test ... but to do something that a doctor cannot do from looking at heart tracing. 'What ...

Part of a tracing, using the standard lead, throat to abdomen, is shown in Fig. 1. While the general form of the electrocardiogram is similar to that of the normal human heart (Fig. 2), except ...

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.
