2. Atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Atrial_tachycardia

   Atrial tachycardia is a type of heart rhythm problem in which the heart's electrical impulse comes from an ectopic pacemaker (that is, an abnormally located cardiac pacemaker) in the upper chambers of the heart, rather than from the sinoatrial node, the normal origin of the heart's electrical activity.

4. Rhythm interpretation - Wikipedia

   en.wikipedia.org/wiki/Rhythm_interpretation

   Sinus tachycardia is another regular rhythm however the ventricular rate is quicker, between 100 - 160 bpm, with a normal PR interval and normal QRS complex. Sinus arrhythmia is an irregular rhythm with a ventricular rate of 60 - 100 normally, however a slow rhythm can be distinguished when the rate is less than 60, the PR interval and QRS ...

6. Multifocal atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Multifocal_atrial_tachycardia

   Multifocal atrial tachycardia is characterized by an electrocardiogram (ECG) strip with three or more discrete P wave morphologies in the same lead, not including that originating from the sinoatrial node, plus tachycardia, which is a heart rate exceeding 100 beats per minute (although some suggest using a threshold of 90 beats per minute ...

7. Right axis deviation - Wikipedia

   en.wikipedia.org/wiki/Right_axis_deviation

   If lead I is positive (translating to 0° on the hexaxial reference system) and lead II is positive (translating to 60°), the electrical heart axis is estimated to fall in the left lower quadrant within the normal range. On the other hand, as shown in Figure 2, if lead I is negative (translating to 180°) and lead II is positive, the ...

8. Tachycardia - Wikipedia

   en.wikipedia.org/wiki/Tachycardia

   Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. [ 1 ]
