Sinus Tachycardia (rhythm, rate, P waves, RR interval, QRS duration) |
Rhythm: regular Rate: >100 bpm (101-180) P waves: positive upright in lead II, one precedes each QRS complex, P waves look alike PR interval: 0.12-0.20 sec and constant from beat to beat QRS duration: 0.11 secs or less unless abnormally conducted |

Sinus Arrhythmia (rhythm, rate, P waves, RR interval, QRS duration) |
Rhythm: irregular and often phasic with breathing (shortens with inspiration lengthens with expiration) Rate: 60-100 bpm P waves: positive upright in lead II, one precedes each QRS complex, P waves look alike PR interval 0.12-0.20 and constant from beat to beat QRS duration: 0.11 or less unless abnormally conducted |
|
|
Sinoatrial (SA) Block (rhythm, rate, P waves, RR interval, QRS duration) |
Rhythym: irregular a a result of pauses caused by the SA block (the pause is the same as or an exact multiple of the distance between two P-P intervals) Rate: usually normal but varies because of pauses P waves: positive upright in lead II, P waves look alike, when present one precedes each QRS complex PR interval 0.12-0.20 and constant from beat to beat QRS duration: 0.11 seconds or less unless abnormally conducted |
|
|
Sinus Arrest (rhythm, rate, P waves, RR interval, QRS duration) |
Rhythm: irregular, the pause is of undetermined length, more than one PQRST complex is missing, and is not the same distance as other P-P intervals Rate: usually 60-100 but varies due to pause P waves: Positive (upright) in lead II, P waves look alike when present, one precedes each QRS complex QRS duration: 0.11 seconds or less unless abnormally conducted |
