2. Atrial flutter - Wikipedia

   en.wikipedia.org/wiki/Atrial_flutter

   Type I atrial flutter, counterclockwise rotation with 3:1 and 4:1 AV nodal block. Atrial flutter with a two to one block. Note the P waves hiding in the T waves in leads V1 and V2. Type I atrial flutter, also known as common atrial flutter or typical atrial flutter, has an atrial rate of 240 to 340 beats/minute.

3. 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 ...

4. Sinus tachycardia - Wikipedia

   en.wikipedia.org/wiki/Sinus_tachycardia

   A 12 lead ECG showing sinus tachycardia. Sinus tachycardia is usually apparent on an ECG, but if the heart rate is above 140 bpm the P wave may be difficult to distinguish from the previous T wave and one may confuse it with a paroxysmal supraventricular tachycardia or atrial flutter with a 2:1 block.

5. Rhythm interpretation - Wikipedia

   en.wikipedia.org/wiki/Rhythm_interpretation

   [1] [2] Ventricular tachycardia is a regular rhythm with a rate of 140-250 bpm, there are no P waves and the main feature is a wide QRS complex (0.12 and greater) Ventricular fibrillation has no p waves or QRS complexes, there are only wavy irregular deflections throughout the heart rhythm, at this point the heart would have a rate of 0 and be ...

7. AV nodal reentrant tachycardia - Wikipedia

   en.wikipedia.org/wiki/AV_nodal_reentrant_tachycardia

   All these ECG-based technologies also enable the distinction between AVNRT and other abnormal fast heart rhythms such as atrial fibrillation, atrial flutter, sinus tachycardia, ventricular tachycardia and tachyarrhythmias related to Wolff-Parkinson-White syndrome, all of which may have symptoms that are similar to AVNRT.
