Fitbit, or Samsung smartwatch is that the former uses 12 leads while the latter uses a single lead. In the simplest terms, the 12-lead device takes multiple readings of your heart, while the single lead takes just one.

To start with we will cover the basics of the ECG, how it is recorded and the basic physiology. The 12-lead ECG misleadingly only has 10 electrodes (sometimes also called leads but to avoid confusion we will refer to them as electrodes). The leads can be thought of as taking a picture...

... and clear understanding leads to mastery of key ECG skills. Yes, you can avoid those dreaded feelings of ECG information overload! HOW IS THE COURSE LAID OUT? You'll enjoy a series of concise videos, quizzes, and practice ECGs as you move towards mastery. It has never been easier...
Abnormal R-wave progression is a common finding which may be explained by any of the following conditions: Myocardial infarction: necrotic myocardium does not generate electrical potentials and therefore there is a loss of R-wave amplitude in the ECG leads reflecting the necrotic area (Figure 10,...
EASI provides a good approximation to the conventional 12-lead ECG. However, EASI may also generate ECG waveforms with amplitudes and durations that differ from the 12-lead ECG. This lead system is generated by using electrodes I, E and A from Frank’s leads, and by adding electrode S to...
The interpretability mechanism successfully underscored the “saw-tooth” pattern of the inverted flutter waves in leads II, III, aVF, loss of the isoelectric baseline, and upright flutter waves in V1, resembling P waves. Figure 2c shows an example of sinus bradycardia, clinically diagnosed by ...
* Frontal plane axis is normal. Slightly early R wave transition in the precordial leads. * No ectopic beats or pauses. It is very important for students to become familiar with normal ECG characteristics before they learn abnormalities. The normal features become a "template" for the interprete...
