2. Automated ECG interpretation - Wikipedia

   en.wikipedia.org/wiki/Automated_ECG_interpretation

   Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.

3. Wiggers diagram - Wikipedia

   en.wikipedia.org/wiki/Wiggers_diagram

   Wiggers diagram with mechanical (echo), electrical (ECG), and aortic pressure (catheter) waveforms, together with an in-ear dynamic pressure waveform measured using a novel infrasonic hemodynography technology, for a patient with severe aortic stenosis.

4. Electrocardiography - Wikipedia

   en.wikipedia.org/wiki/Electrocardiography

   A standard 12-lead ECG report (an electrocardiograph) shows a 2.5 second tracing of each of the twelve leads. The tracings are most commonly arranged in a grid of four columns and three rows. The first column is the limb leads (I, II, and III), the second column is the augmented limb leads (aVR, aVL, and aVF), and the last two columns are the ...

5. Cardiac cycle - Wikipedia

   en.wikipedia.org/wiki/Cardiac_cycle

   The cycle also correlates to key electrocardiogram tracings: the T wave (which indicates ventricular diastole); the P wave (atrial systole); and the QRS 'spikes' complex (ventricular systole)—all shown as color purple-in-black segments. [1] [2] The Cardiac Cycle: Valve Positions, Blood Flow, and ECG The parts of a QRS complex and

6. Atrioventricular block - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_block

   An electrocardiogram, or ECG, is used to differentiate between the different types of AV block. In AV block, there is a disruption between the signal traveling from the atria to the ventricles. This results in abnormalities in the PR interval, as well as the relationship between P waves and QRS complexes on the ECG tracing.

7. P wave (electrocardiography) - Wikipedia

   en.wikipedia.org/wiki/P_wave_(electrocardiography)

   If at least three different shaped P waves can be seen in a given ECG lead tracing, this implies that even if one of them arises from the SA node, at least two others are arising elsewhere. This is taken as evidence of multiple (i.e. at least two) ectopic foci , and is called multifocal (or more correctly, multiform) atrial rhythm if the rate ...

8. PR interval - Wikipedia

   en.wikipedia.org/wiki/PR_interval

   Schematic representation of a normal sinus rhythm EKG wave. In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration.

9. ST segment - Wikipedia

   en.wikipedia.org/wiki/ST_segment

   Schematic representation of normal ECG In electrocardiography , the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms). It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave.
