Question | Answer |

Heart rate and rhythm change, cardiac cycle stays normal | Sinus arrhythmia |
cardiac cycle is normal, along with heart rate 60 to 100, and rhythm | NSR. Normal Sinus Rhythm |
Cardiac cycle and rhythm is normal, just heart rate is < 60 | Sinus bradycardia cardiac cycle and rhythm is normal, just heart rate is > 100 but < 160 |
Fluctuating heart rate, no rhythm | Sinus arrhythmia |
slow her heart rate usually in the 60s or can turn Brady Missing 1 cardiac cycle | Sinus block |
Usually 15 big boxes of polarization Heart rate is usually normal until arrest occurs Missing 2 cardiac cycle is 3.52 sec. of polarization state = True sinus arrest | Sinus arrest |
Absent P-wave | Junctional |
Junctional heart rate | 40 to 60 bpm |
Must have regular cardiac cycle with a few ab normal cycles P-wave absent or inverted Can be LETS or GEMINEY premature contractions brakes rhythm Normal sinus rhythm with PJCs | PJC |
Entire rhythm strip should be absent or have inverted P waves If you cardiac cycle is missing SKIPPED HEART BEAT | Escape junctional rhythm EJR |
Entire rhythm strip should be absent or have inverted P waves HR should be 60 to 100 bpm | Accelerated junctional rhythm AJR |
Entire rhythm strip should be absent or have an inverted P waves HR should be 100 to 180 bpm | Junctional tachycardia JTR |
PRI are all abnormal, but the same rate on all cardiac cycles Not a true HB, just a delay | Atrial ventricular 1st° heart block |
Entire rhythm strip should be absent or have invited P waves HR should be 60 to 100 bpm | Accelerated junctional rhythm AJR |
Entire rhythm strip should be absent or have an inverted P waves HR should be 100 to 180 bpm | Junctional tachycardia JTR |
PRI are all abnormal, but the same rate on all cardiac cycles Not a true HB, just a delay | Atrial ventricular 1st° heart block |
PRI gradually gets longer and longer Eventually you should see a lonely P-wave, QRS drops so you don't see it | Atrioventricular 2nd° heart block Mobitz type 1 Wenckebach |
Same Characteristics of 1st° , however PRI can be normal or abnormal consistently the same rate in every cardiac cycle Lonely P waves and the rhythm | Atrioventricular 2nd° heart block Mobitz type 2 Classical |
PRI, chaotic.it's cardiac cycle's PRI is different. NO rhythm Lonely P waves present Only AVHB that can have PVCs, abnormal QRS complexes | Atrioventricular 3rd° heart block: Complete Heart Block |
P wave abnormal/hidden + 1:1 | Atrial |
Must have regular cardiac cycle with a few ab normal cycles P-wave abnormal Can be let's or Geminey Premature contraction brakes rhythm Normal sinus rhythm with PACs | Atrial PAC |
Heart rate 140 to 250 | Atrial tachycardia |
Heart rate must be > 200 or see if P wave T wave merger | For a SVT |
P waves are very small. They are now F with productions P waves quiver, or shake so you will see fine or coarse pattern | Atrial fibrillation |
P- waves are sharp. Sawtooth like Can be in ratio or pattern | Atrial flutter |
QRS abnormal shape and bazaar Complex bigger than three small boxes Heart rate 20 to 40 bpm | Ventricular |
Must have regular cardiac cycle with a few abnormal cycles QRS During PVC, P waves are absent, NSR with PVCs, ST segment can be nonexistent T-wave goes in the opposite direction Can be Lets or GEMINEY Premature contractions brakes | Ventricular PVC |
Peaked and symmetrical in shape, do not see P waves, or super Duper hard to see or catch them, T waves an opposite direction, bunny ears look | Ventricular tachycardia |
V Tach leads to V Fib Think of Jello like appearance, they are waves Non-symmetrical | Ventricular fibrillation |
HR should be 20 to 40 bpm All cycles are abnormal due to PVCs Rhythm should be aregular | Idoventricular rhythm I DVR |
HR should be 40-100 BPM Are cycles or abnormal did to PVC is Rhythm should be regular | Accelerated idioventricular rhythm AIDVR |
multifocal or change in morphology, sharp peaks | Torsades De Pontes |
4 or more PVCs together in the middle of a normal sinus rhythm | Run / salvo |
P-wave abnormally long | AV |
