Identifying normal sinus rhythm and common arrhythmias on a 12-lead EKG strip, one rhythm per card.
40 cards · basic cards · AI-written, checked twice. Edit anything.
- EKG shows regular rhythm, rate 60-100, normal P wave before each QRS, PR interval 0.12-0.20 seconds, QRS 0.06-0.10 seconds.
- Normal sinus rhythm
- Regular rhythm at rate below 60 bpm with normal P waves and PR intervals.
- Sinus bradycardia
- Regular rhythm at rate above 100 bpm with normal P waves and PR intervals.
- Sinus tachycardia
- Irregular rhythm with no visible P waves, irregular baseline, ventricular rate typically 100-150 bpm.
- Atrial fibrillation
- Regular ventricular rate with saw-tooth or flutter wave pattern between QRS complexes.
- Atrial flutter
- Sudden onset of rapid rhythm (150-250 bpm) with narrow QRS complexes and regular intervals.
- Paroxysmal supraventricular tachycardia (PSVT)
- Premature QRS complex with abnormal P wave preceding it, followed by normal sinus beat.
- Premature atrial contraction (PAC)
- Premature wide QRS (greater than 0.12 seconds) with no preceding P wave.
- Premature ventricular contraction (PVC)
- Rapid regular rhythm (150-250 bpm) with wide QRS complexes (greater than 0.12 seconds).
- Ventricular tachycardia
- Completely chaotic baseline with no discernible P waves, QRS complexes, or T waves.
- Ventricular fibrillation
- Rapid regular rhythm with visible abnormal P waves but normal QRS width.
- Atrial tachycardia
- Rhythm originates in AV junction; P wave buried within or immediately after QRS complex.
- Junctional escape rhythm
- PR interval consistently prolonged (greater than 0.20 seconds) but all P waves conduct to QRS.
- First-degree AV block
- Progressive lengthening of PR interval until one P wave fails to conduct, then pattern repeats.
- Second-degree AV block Type I (Wenckebach)
- Constant PR interval with occasional P waves that fail to conduct to ventricle.
- Second-degree AV block Type II
