1. Normal Sinus Rate: 60-100 bpm, Rhythm: Regular, P wave: One before every QRS, PR: 0.12-0.20
Rhythm (NSR) sec, QRS: <0.12 sec

2. Sinus Tachycar- Rate: >100 bpm, regular, P waves present, narrow QRS. Causes: Pain, fever, anxiety,
dia exercise, hypovolemia, shock, sepsis.

3. Nursing for Sinus Treat the cause, oxygen if needed, IV fluids, beta blockers if ordered.
Tachycardia

4. Sinus Bradycar- Rate: <60 bpm, regular, P waves present, narrow QRS. Symptoms: Dizziness, syn-
dia cope, hypotension, fatigue.

5. Treatment for Si- Observe if asymptomatic; atropine if symptomatic; pacing if needed.
nus Bradycardia

6. Atrial Fibrillation Irregularly irregular rhythm, no identifiable P waves, narrow QRS. Risk: Stroke.
(A-Fib)

7. Treatment for Rate/rhythm control, anticoagulants, cardioversion if unstable.
Atrial Fibrillation

8. Supraventricular Rate: 150-250 bpm, regular, P waves hidden, narrow QRS.
Tachycardia (SVT)

9. Treatment for Vagal maneuvers, adenosine, synchronized cardioversion if unstable.
Supraventricular
Tachycardia

10. Ventricular Wide regular rhythm, no P waves. Always check for a pulse.
Tachycardia
(V-Tach)

11. Treatment for Antiarrhythmics or synchronized cardioversion if unstable.
V-Tach with Pulse
