Study Notes
Cardiac Rhythms
- Sinus Bradycardia: Low heart rate; check for symptoms and potential treatment.
- Reentry Supraventricular Tachycardia: Rapid heart rate; regular rhythm; may cause palpitations.
- Second-degree AV Block (Mobitz II): Characterized by intermittent non-conduction of impulses; may lead to complete heart block.
- Agonal Rhythm/Asystole: Extremely low or absent electrical activity; immediate intervention required.
- Third-Degree AV Block: Complete block of impulse from atria to ventricles; requires pacing.
- Monomorphic Ventricular Tachycardia: Consistent QRS complexes; can lead to hemodynamic instability.
- Sinus Tachycardia: Elevated heart rate; typically responds to treating underlying conditions.
- Atrial Fibrillation: Irregularly irregular rhythm; may be rapid; anticoagulation considered.
- Course Ventricular Fibrillation: Chaotic heart rhythm; definitive treatment is defibrillation.
- Polymorphic Ventricular Tachycardia: Varying QRS morphology; associated with QT prolongation.
- Second-degree AV Block (Mobitz I/Wenckebach): Gradually increasing R-R intervals with a dropped beat.
- Normal Sinus Rhythm: Regular rhythm with a heart rate of 60-100 bpm; indicates optimal heart function.
- Pulseless Electrical Activity (PEA): Organized electrical activity without effective cardiac output; CPR necessary.
- Fine Ventricular Fibrillation: Subtle chaotic rhythm; requires immediate defibrillation.
- Atrial Flutter: Rapid atrial rate with identifiable "sawtooth" pattern; may lead to thromboembolism.
Clinical Interventions
- Immediate Electrical Cardioversion: Indicated for unstable patients with wide-complex tachycardia and hypotension.
- Fluid Bolus (Normal Saline 250-500 mL): Administered for hypotensive patients with acute coronary syndrome unresponsive to nitroglycerin.
- Amiodarone 300 mg: Next drug after two shocks in pulseless ventricular tachycardia; first-line for symptomatic VT.
- 150 mg IV Push Amiodarone: Recommended second dose for refractory ventricular fibrillation.
- Adenosine 6 mg: First-line treatment for stable narrow-complex tachycardia unresponsive to vagal maneuvers.
- Seeking Expert Consultation: Recommended for asymptomatic wide-complex tachycardia with history of angina.
- Avoid Nitrates: Contraindicated with recent use of phosphodiesterase inhibitors, particularly within 12 hours.
- Epinephrine 2 to 10: Essential in cases of cardiac arrest or severe bradycardia to optimize coronary perfusion.
