Key Points about Complete Heart Block:
- Definition: Complete heart block (third-degree AV block) is a condition where there is no conduction between the atria and ventricles, resulting in a complete disassociation of the heart’s electrical signals.
- Causes: Common causes include ischemic heart disease, fibrosis of the conduction system, myocarditis, medication effects (e.g., beta-blockers, calcium channel blockers), and congenital conditions.
- Symptoms: Symptoms include bradycardia, fatigue, dizziness, syncope (fainting), and signs of heart failure in severe cases.
- Diagnosis: Diagnosed using ECG, which shows complete atrioventricular dissociation with independent atrial and ventricular rhythms. Further assessment may involve echocardiography to evaluate cardiac structure.
- Management: Urgent pacing in symptomatic cases is essential. Permanent pacemaker implantation is the mainstay treatment for persistent complete heart block. Medication review and cessation of any causative drugs are also critical.
- Complications: If left untreated, complications include syncope, heart failure, and an increased risk of sudden cardiac death.
We hope you find these MSRA revision resources helpful and engaging as you prepare for the MSRA.
